How to Reverse Skin Aging (2025)

[RapAdmin]

And the research and clinical validation on this Sodium Silicate gel:

I searched the scientific literature and patents; the verdict is: the evidence for sodium silicate (or related silicates) as a skin-health or tightening agent is very limited and mostly speculative, with more support in patents than in peer-reviewed clinical trials. Below is a breakdown of what is known, what’s claimed, and where the gaps lie.

---

What is Sodium Silicate, and How It Might Be Proposed to Work in Skin

• Sodium silicate is a soluble silicate salt (often “water glass”) with chemical formula Na₂SiO₃ (or mixtures of silicates). It forms silicate networks, gels, and can act as a film former when dried.
• In topical cosmetic patents and formulations, sodium silicate is sometimes used in film-forming, contractile gels: after application and drying, the silicate film is proposed to contract, pulling the skin temporarily tight like a “second skin.” (Film contraction = mechanical tightening) (Justia Patents)
• Some patents (e.g. WO / US skin-tightening composition patents) include 0.5–4% sodium silicate by silica content in water gels or emulsions, and claim that their compositions contract 0.2–0.9 inches, smooth skin, form stable films, etc. (Google Patents)
• The patent literature also suggests that sodium silicate (or silicate + polyvalent silicate) film formers can transiently tighten the skin by adhesion + contraction, smoothing surface irregularities immediately upon drying. (Justia Patents)
• One U.S. patent notes sodium silicate has “dramatic, instant results” as a contractile film former, but also warns that films lose elasticity, whiten, crack, or peel over time. (Justia Patents)
• Another patent (US20170189298A1) describes formulations with sodium silicate that form persistent, elastic skin films when the pH is ~10–12. (Google Patents)

So the main mechanistic hypothesis is mechanical / film contraction — not deep remodeling of dermal collagen.

What Clinical / Scientific Evidence Exists

I found very sparse peer-reviewed or clinical evidence supporting meaningful long-term skin-health or tightening benefits of sodium silicate.

Supporting/Indirect Evidence

• A review titled “Three clinical studies showing the anti-aging benefits of SS (sodium silicate)” is listed in PubMed (PMID 20883290). The summary says:

  “All three studies demonstrate the significant anti-aging effects of SS … benefits may derive from its intrinsic stratum corneum exfoliation effects.” (PubMed)
  But digging deeper:

  • The article is old and not well indexed; I could not locate the original full texts or strong randomized controls.
  • It suggests SS may exfoliate stratum corneum and produce visible smoothing, rather than deep dermal change.

• A 2025 clinical trial (cosmoderma.org) of Mesoporosil® (a silicate-containing supplement) reports improved skin firmness, hydration, elasticity over 12 weeks, with high satisfaction and safety. (Cosmoderma)

  • This is oral or nutritional silicate, not topical sodium silicate gel.
  • It doesn’t prove topical sodium silicate interacts with the skin in the same way.

• The CIR (Cosmetic Ingredient Review) “Amended Safety Assessment of Silica and Silicates” addresses safety of silicate and silica compounds in cosmetics. It notes that at high concentrations, some silicates (e.g. sodium metasilicate) can be irritating or corrosive, so concentrations must be managed. (CIR Safety)

• A patent for sodium silicate in skin-smoothing gels claims smoothing and contraction effects in vitro, but these are patent claims, not clinical trials. (Google Patents)

• In cosmetic industry reporting, sodium silicate is flagged as a “sneaky tightener” ingredient used in creams to create temporary tightening via film contraction (like “saran wrap”) — i.e. instant but transient tightening. (Cosmopolitan)

Limitations & Gaps

• No solid double-blind randomized controlled trials comparing sodium silicate gel vs placebo for improvements in elasticity, wrinkle depth, collagen density etc., were found in the literature search.
• The existing patents, while detailed, are not peer-reviewed evidence and often describe hypothetical or idealized contraction metrics, not long-term biological endpoints.
• The contraction effect is likely superficial and transient (as suggested in patents: films lose elasticity, crack, whiten over time) rather than sustained structural remodeling. (Justia Patents)
• Potential for skin irritation or adverse effects at higher concentrations: the safety review warns that sodium metasilicate is corrosive undiluted; silicates have dose-dependent irritation potential. (CIR Safety)

Interpretation: What You Can Reasonably Expect

Given what we know:

Claim	Likelihood / Strength	Mechanism
Instant tightening / “pull” of skin	Moderate likelihood (short-term)	Film contraction: the gel dries and shrinks slightly, pulling superficial skin taut
Smoothing of fine lines	Low-moderate (visual smoothing)	The taut film hides micro-reliefs by flattening the surface; superficial effect
Long-term skin tightening / remodeling	Very low (no solid evidence)	No data supporting deep collagen induction or persistent dermal change
Hydration / barrier improvement	Low	Silicates do not inherently hold water like humectants; film may reduce TEWL modestly

Hence, sodium silicate gel may offer instant, superficial “tightening” or smoothing effect (a cosmetic effect), but there’s no strong clinical evidence it improves skin health (collagen, firmness) in a sustained way.

If you like, I can try to dig further — locate obscure or non-English clinical trials of sodium silicate gels in dermatology, translate them, and report whether any show durable tightening beyond the film effect. Do you want me to dig that deeper?

https://bellafill.com/bellafill-cosmetic/

I was curious if anyone here has experience with BellaFill to share?

[AlexKChen]

does anyone know how to “fill up” nasolabial folds?

2) Devices that thicken and tighten (no volume added)

Good for microscopic descent and laxity when you’re not ready for filler.

• RF microneedling (Genius, Morpheus8, Potenza): stimulates collagen/elastin in dermis; improves texture and firmness. Expect 2–3 sessions, 4–6 weeks apart.
• Micro-focused ultrasound (Sofwave/Ultherapy light passes): collagen tightening in the SMAS/dermis. One session, results over 3–6 months.
• Monopolar RF (Thermage FLX): global tightening; subtle but camera-visible.

These won’t “lift” 0.3 mm like a car jack, but they reduce sag signal by firming the “fabric” over the frame.

3) Add or restore volume where it actually helps

Tiny, targeted, and not in the crease itself.

• Hyaluronic acid filler (e.g., Voluma/Volux/Restylane Contour) placed deep:
  • Planes: supraperiosteal lateral zygoma and deep medial cheek fat to re-support the ogee curve.
  • Amounts: often 0.3–0.8 mL per side to correct a subtle change. Micro-aliquots with a cannula. Goal is light redirection, not chipmunk cosplay.
  • Longevity: ~9–18 months.
• Biostimulators if you want “volume via collagen”:
  • PLLA (Sculptra): 2–3 sessions, 6–8 weeks apart; builds your own collagen over months for a gentle, durable lift.
  • Hyperdilute CaHA (Radiesse): more collagen stimulation than bulk; improves firmness and skin quality.

4) When to consider fat

• Micro-fat/nano-fat grafting if you’re already very lean or want a longer-term solution. Overkill for 0.3 mm unless you’re doing other work.

5) Things that sound smart but don’t help much

• “Cheek exercises,” gum marathons, facial yoga. You’ll carve dynamic lines and stress ligaments. Hard pass.
• Slapping filler directly into the nasolabial crease as a first move. Modern approach supports the midface above and lateral so the fold softens naturally.

Safety notes, especially important for Asian faces

• Preserve the ogee curve and midface balance; avoid medial overfill that widens the midface or blunts delicate contours.
• Demand an injector who uses cannula in high-risk zones and understands the angular/infraorbital vessels. Vascular occlusion is not a cute plot twist.

I was thinking about aged skin, and how to tighten it (not change the 3d structure – add or remove volume – just firm it up). This is not advice for something to try. It could be dangerous if you did. Instead, think of it as stuff to search for – I.e. look for products that are shown to be SAFE, that use similar mechanisms.

Ok, it all started when I watched this video about how to make bioplastics in your kitchen (very cool video!):

Radiative Cooling Aerogel from Potatoes (and other DIY bioplastics)

It got me to thinking that if you could somehow increase the cross-linking of collagen fibers just below the surface of the skin, then it should tighten things up (I think, anyhow). Plasticizers like glycerin and honey work opposite a cross-linking agent; so, it might be bad for firming skin if honey were to penetrate too deeply into skin.

Tannins are apparently a good cross-linking agent. They can be found in black teas in high amounts. But they are large molecules, so won’t penetrate skin easily without a carrier agent. Urea is one such agent, DMSO is a more potent one.

If one could get tannins (in very small amounts) into skin, it probably wouldn’t work to cross-link passively; you’'d need to shake or massage the skin with like a massage gun or something. And you’d probably need to repeat it several times before you start to see an effect.

Now here’s the dangerous part: tea is “dirty”, and you don’t want all the stuff in it deep into your skin. If you want something like this to work, it would have to be medical-grade, and tested in clinical trials to be safe. I don’t happen to know of any procedures where something like this has been tried; but they may exist for all I know.

Once again, please don’t try this!

[LaraPo]

You could try Thermage which is a non-invasive skin tightening treatment that uses radiofrequency (RF) energy to stimulate collagen production deep within the skin.

[starspawn0]

I don’t think that actually works – maybe very mild. Increasing collagen doesn’t address the cross-linking problem. I guess the hope is that the body would fix this on its own, if you increase the supply of collagen; but it’s not a given.

Anyways, I personally don’t have much to worry about at the moment; but in 5 to 10 years… I’m not so sure (given what I see the typical skin of people in their 60s looks like).

Addendum; A paper on the effects of Tannic acid on cross-linking in sheep skin:

https://www.sciencedirect.com/science/article/abs/pii/S0142961296002025

The degree of cross-linking was proportional to the uptake of tannic acid, which varied between 6 and 35 wt%.

Also, I asked Google’s Gemini 2.5 Pro to confirm my suspicions about the necessity of cross-linking for firm skin:

‎Gemini - Collagen Crosslinking and Skin Laxity

You are correct. A lack of normal, healthy collagen crosslinking is a key reason for skin becoming loose, fragile, and overly stretchy.

This process is central to the structure and integrity of your skin. Here’s a detailed breakdown of why this happens.

What Are Exosomes, The Lastest Skincare Ingredient Exciting Dermatologists?

Experts are whispering that this could be skincare’s newest fountain of youth.

Dermatologists Are Buzzing About A New Ingredient That Can Reverse Nearly...

The long and the short of it is…no. We don’t yet have enough scientific evidence to say with confidence that exosomes can significantly benefit the appearance of the skin. And there’s not yet a consensus on which sources of exosomes are best for which cosmetic outcomes, Dr. Eber says.

Here’s why there’s still lots of uncertainty: For one, a majority of the research investigating exosomes in cosmetics are animal studies or studies that involve human cells in a petri dish, not real humans. And while the results of those studies are indeed helpful, they’re not enough to confirm how safe and effective exosomes are when people use them, according to that 2025 review. And when it comes to the human studies that do exist, many of them include a small number of participants, which makes it difficult to draw any hard and fast conclusions. “There’s still a lot of work to be done,” Dr. Kaminer says.

There’s also a major lack of standardization when it comes to how, exactly, exosomes are harvested and used in research and cosmetics, Dr. Garibyan says. For instance, in the lab, there’s no singular gold-standard way to isolate exosomes from other “debris” that cells can release, Dr. Wyles explains. This can make it difficult to differentiate between exosomes and other materials of a similar size such as viruses, Dr. Eber adds. It also makes it difficult to differentiate between exosomes containing helpful information and ones containing potentially harmful messages. “It’s really hard to filter out just the exosomes” that you want, Dr. Wyles says.

[relaxedmeatball]

As someone on the Editorial board of an EV journal, I highly advise against using any sort of “exosome” treatments on yourself. The cosmetic products do not have cGMP manufacture, they don’t have defined critical quality attributes. You simply don’t know the safety. For anything topical (serums to go on the skin) they likely don’t penetrate. If you disrupt the skin barrier (micro needling, or injection) there are plenty of case reports and news articles out there of things going horribly wrong with exosome treatments. I won’t dig up the pictures here, but there are people who ended up with permanent scarring, a few people who have died from sepsis etc. It’s not worth it.

Abstract of a paper from South Korea (not in a great journal, but might lead somewhere; and it’s probably not even that original as far as skin applications are concerned):

https://www.mdpi.com/1996-1944/14/19/5788

(Note that it’s a porcine model, not human-tested.)

This study aimed to prove that RFP [riboflavin phosphate] combined with blue light (BL) can increase collagen crosslinking density, improving its mechanical properties in skin tissue and enhancing skin elasticity. We confirmed the RFP-induced photo-crosslinking in pure collagen by studying changes in its dynamic modulus and matrix morphology using collagen hydrogels. We also measured the changes in the mechanical properties after applying photo-crosslinking on porcine skin. The Young’s modulus (1.07 ± 0.12 MPa) and tensile strength (11.04 ± 1.06 MPa) of the porcine skin after photo-crosslinking were 2.8 and 3.5 times better compared to those of normal porcine skin, respectively.

Stimulation of Cytoglobin Expression and Improvement in ROS-Related Aging Markers in Skin Cells with Tropaeolum majus Extract

Reactive oxygen species (ROS) and mitochondrial dysfunction play a major role in skin aging. Due to Tropaeolum majus’ suggested protective actions against ROS, a link between T. majus extract and increased cytoglobin (CYGB) expression was evaluated for cultured skin cells. Human dermal fibroblasts and keratinocytes were treated with 0.5% v/v T. majus extract and the effect of this treatment on the expression of CYGB and on a range of cellular markers of aging were evaluated. In fibroblasts, the treatment with the extract was associated with an increase in CYGB levels. It also decreased ROS concentrations, improved the function of mitochondria, and stimulated the synthesis of collagen and elastin. Moreover, it downregulated a set of genes controlling the terminal differentiation of keratinocytes. T. majus extract activates oxygen transport within natural killer cells and thus enhances their activity, suggesting a potential senolytic effect. This extract seemed to exert a protective effect on various aging pathways such as ROS production, mitochondrial dysfunction, and collagen homeostasis, playing a promising role against skin aging.

Open access paper: https://www.mdpi.com/2079-9284/12/5/230

Brief AI Summary:

Here’s a summary of the paper “Stimulation of Cytoglobin Expression and Improvement in ROS-Related Aging Markers in Skin Cells with Tropaeolum majus Extract” (Cosmetics 2025) and details on the dosing/frequency and effect sizes they observed.

Summary

The study investigates how an extract of Tropaeolum majus (nasturtium) enriched in arabinogalactans (prepared by the company SILAB) acts on skin-cells (human dermal fibroblasts and keratinocytes) in vitro with respect to aging-related pathways. MDPI

Key points:

• Aging of skin is associated with increased reactive oxygen species (ROS), mitochondrial dysfunction, and breakdown of extracellular matrix (ECM: collagen & elastin) in fibroblasts and keratinocytes. MDPI+2MDPI+2
• The protein cytoglobin (CYGB) is up-regulated by the extract, and CYGB is proposed to help reduce ROS, support oxygen delivery and protect mitochondria. MDPI
• The extract treatment reduced ROS levels (both cytosolic and mitochondrial), improved mitochondrial respiration and ATP production, increased cell proliferation, and significantly boosted collagen and elastin synthesis in fibroblasts. In keratinocytes, it also modulated gene expression—down-regulating genes involved in terminal differentiation/cornified envelope formation. MDPI
• They also evaluated immune cells (NK cells) under hypoxic conditions: the extract restored NK cell activity (which declines under hypoxia) by 84 %. MDPI
• The authors conclude that T. majus extract may help protect against skin aging by reducing ROS, improving mitochondrial function, boosting ECM synthesis and promoting more regenerative keratinocyte states. MDPI

Please provide an analysis and summary of this patent from Silab: patent FR2965483

Response:

Here’s a crisp, practical read-out of FR2965483 (SILAB) — “Cosmetic use of a Tropaeolum majus (nasturtium) extract as an active for promoting oxygenation of skin tissue.”

What the patent claims (in plain English)

• Purpose / use-claim: Using a nasturtium extract as a cosmetic active to improve skin oxygenation. The mechanism emphasized is (a) restoring hypoxic stress response (via HIF-1α induction) and/or (b) facilitating intracellular oxygen diffusion (via upregulating cytoglobin). Google Patents
• Composition range: Topical compositions containing the active at 0.01–20 wt% of the finished product. Patent Images
• Nature of the active: An extract enriched in arabinogalactans (low DP 2–6), and depleted in polyphenols (< 0.2% of dry matter). The extract is preferably obtained by aqueous extraction of aerial parts. Typical analytics: dry matter 10–55 g/L; total sugars 2–16 g/L (≈14–46% of dry matter); uronic acids 3–5% of dry matter. Google Patents

How they make it (extraction outline)

• Process (example):
  1. Solubilize powder of aerial parts of T. majus in water (e.g., 100 g/kg);
  2. Separate soluble/insoluble phases;
  3. Remove polyphenols by adsorption to get < 0.2% polyphenols;
  4. Filter, optionally decolorize/deodorize, then sterile filtration. Google Patents+1

Evidence provided in the patent

• In vitro (aging fibroblasts): Fractions tested at 0.25% under hypoxia show induction of HIF-1α (restored hypoxic response) and support for cytoglobin synthesis (oxygen trafficking). The active fraction is the neutral carbohydrate (arabinogalactan-rich) fraction. Patent Images
• In vivo (cosmetic study): 28-day, twice-daily facial application of an emulsion with 3% nasturtium extract (vs placebo). The a* colorimetric parameter (redness/rosiness linked to oxygenation) increased by +9.5% versus placebo, interpreted as improved oxygenation/complexion radiance.

Practical formulation guidance inferred from the text

• Dosage in finished products: 0.01–20% (the human in-vivo example used 3% in an emulsion, bid x 28 days).

Sources

Short answer: I couldn’t find any commercially sold, consumer-facing products that publicly state their formula is an emulsion containing exactly 3% nasturtium (Tropaeolum majus) extract. Brands virtually never disclose the exact % of a single botanical—SILAB’s OXYGESKIN® has a recommended use level of 1–3% in finished formulas, but the specific % used by any brand is typically undisclosed. (SILAB)

That said, here are products that explicitly claim to use OXYGESKIN® / Tropaeolum majus Flower/Leaf/Stem Extract (so they’re plausible candidates to be in the 1–3% window), with current pricing and size. I’m flagging the concentration as “% not disclosed” because none of these pages publish an exact percentage:

Negative results on Collagen for skin:

Effects of Collagen Supplements on Skin Aging: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Results

A total of 23 RCTs with 1474 participants were analyzed. In a meta-analysis of all 23 RCTs, collagen supplements significantly improved skin hydration, elasticity, and wrinkles. However, in the subgroup meta-analysis by funding source, studies not receiving funding from pharmaceutical companies revealed no effect of collagen supplements for improving skin hydration, elasticity, and wrinkles, while those receiving funding from pharmaceutical companies did show significant effects. Similarly, high-quality studies revealed no significant effect in all categories, while low-quality studies revealed a significant improvement in elasticity.

Conclusions

There is currently no clinical evidence to support the use of collagen supplements to prevent or treat skin aging.

[LukeMV]

I think Brad Stanfield, Siim Land, and Physionic debunked this quite well. In fact, it only made collagen sound more compelling for skin.

[relaxedmeatball]

I am very sceptical. You can also tell things are a shitshow when there is absolutely no consensus in the study design or results. For example, looking at Table 1 of the paper, you have collagen doses ranging from 0.5g per day to 50g per day, (and both of those studies claim improvements). That’s a 100-fold dose range. We wouldn’t do that with any other intervention, would we? That’s a first warning sign that you’re in a “field” of research where people are just making things up.

And if we’re talking about oral supplementation, I find it a bit baffled how/why it could work. Collagen is a pretty damn big triple helix protein. How much going to get through your stomach acid, digestive enzymes, then be absorbed, travel around the blood stream, then integrate into your skin?

The theory is that we lose dermis collagen as we age, so replacing it will slow skin aging. Apparently, people lose collagen at around 1% per year. So if you think about it, is it really possible that supplementing for 8-12 weeks going to reverse that to a degree that can be measured? Even if you completely halted all age-related collagen degradation over 12 weeks, you’d have an eventual difference of 0.23% between the groups. To get anything bigger than that, you’d be actually building collagen back into your skin.

Lastly, consider that an 8oz steak contains ~3-5g of collagen. If you enjoy the tougher parts (brisket, shank, or the edge of your sirloins etc), you could have 6-10g in one serving. If you cook things like chicken soups, you release out gelatin, which is better absorbed. So basically, if you have a decent diet, you’re already getting collagen in the range of the doses used in those studies.

It’s theoretically possible that something else is going on, such as modulating enzymes which remodel the extracellular matrix. Or maybe affecting the fibroblasts in the skin. But none of that has been convincingly shown IMO.

from a group called “LongevityDocs”

If you’re seeing more patients interested in “anti-aging skincare,” you’re not alone — but as Dr. Saranya Wyles, Mayo Clinic, reminded us at Peptide Mastermind in NYC, the real story starts inside the cell.

Skin is the first place longevity shows up — and its dysfunction can be a biomarker for what’s happening in the vascular, metabolic, and immune systems.

The problem?

Most doctors aren’t trained to read those skin signals or understand what to do about them. And patients get funneled into short-term aesthetic fixes instead of long-term protocols that actually protect healthspan.

4 Thoughts from Dr. Wyles

1. Senescent cell accumulation shows up visibly in skin as thinning, inflammation, and fragility — especially postmenopause.
2. mTOR inhibition (via topical or oral rapamycin) is one of the most promising areas for reducing these visible and internal signs of aging.
3. Skin is a “window into tissue regeneration” — and optimizing NAD+ levels can help restore repair cycles.
4. Barrier dysfunction and immune dysregulation go hand in hand — and skincare alone won’t fix it.

If you’re seeing these signs in your patients — you’re already treating longevity, whether you call it that or not.

Our role is to give you the clinical, operational, and peer-based structure to turn that intuition into confident practice.

Catch Dr. Wyles’ full talk — plus protocols from Dr. Yurth, Dr. Koniver, and more.

Following having a PICC line removed from my arm about 2 days ago, the nurses put a band-aid over the little hole in my arm – only, it was no ordinary band-aid, and it gave me the idea for better delivery mechanisms for skin topicals. Basically, they used a Tegaderm dressing, which has a large, transparent, very sticky covering, and then a little square gauze in the middle. I had had those before when seeing a doctor years back, but never knew what they were called; this time, however, they wrote it down on the instructions for when to take it off (they said “24 hours”). I think this can be purchased over-the-counter. I could imagine putting some topicals on that gauze, and then sticking it to the skin. It would really hold in the water, far better than an occlusive. I bet it would make some topicals work 2x better. Many topicals have poor skin permeability; however, if you can keep them dry, long enough, they eventually do at least partially penetrate the skin. (Though, it’s really hard to get the Tegaderm band-aid off! – it’s almost like it’s super-glued onto your skin!)

Another use might be to tighten skin, by putting the sticky part (which you can cut off) on skin and then pulling it in some direction. I’d guess it would stay stuck on your skin for about a week or more before degrading; and it would be mostly transparent, with the only giveaway being the slight glossiness in just the right lighting.
