The anti-inflammatory, antioxidant, stem cell maintenance, and metabolic activities of calorie restriction contribute to its beneficial effects on the skin. Calorie restriction mimetics, including metformin, rapamycin, and peroxisome proliferator-activated receptor agonists, show similar prevention to calorie restriction against skin aging [17].

Conclusion

It was concluded that although calorie restriction is the most effective intervention to prolong the life of organisms and prevent age-related diseases, its effects on aging and skin diseases can be significant. Dietary lifestyles can affect epithelial lineages such as the skin and intestine. The impact of Ramadan fasting on skin health can be compared with the effect of other types of fasting, including periodic dieting, calorie restriction, dietary restriction, dietary manipulation, and intermittent, short-term, and prolonged fasting. However, despite the scarcity of studies on the topic, no serious health risks have been reported and, therefore, patients who wish to fast should be warned about the importance of continuing their treatment and the administration of transdermal/topical medications.

Research Progress in Skin Aging, Metabolism, and Related Products

Abstract

In recent years, skin aging has received increasing attention. Many factors affect skin aging, and research has shown that metabolism plays a vital role in skin aging, but there needs to be a more systematic review. This article reviews the interaction between skin metabolism and aging from the perspectives of glucose, protein, and lipid metabolism and explores relevant strategies for skin metabolism regulation. We found that skin aging affects the metabolism of three major substances, which are glucose, protein, and lipids, and the metabolism of the three major substances in the skin also affects the process of skin aging. Some drugs or compounds can regulate the metabolic disorders mentioned above to exert anti-aging effects. Currently, there are a variety of products, but most of them focus on improving skin collagen levels. Skin aging is closely related to metabolism, and they interact with each other. Regulating specific metabolic disorders in the skin is an important anti-aging strategy. Research and development have focused on improving collagen levels, while the regulation of other skin glycosylation and lipid disorders including key membrane or cytoskeleton proteins is relatively rare. Further research and development are expected.

That first sentence in the conclusion is odd. The “although” seems out of place.

Maybe English is not your first language, but to me it sounds 100% correct. Maybe it’s better to stick to the content itself as opposed to editing (especially if it is not your strong suit LOL) :rofl: :smile:

English is my first language. And I edit. “Although” is defined as “in spite of the fact that”, and therefore requires a contradiction in the sentence. Ex. Although we left late, we still arrived on time. Although they had known one another for a long time, they didn’t particularly like each other. In this case we have “although calorie restriction is the most effective” followed by “its effects… can be significant”, but structurally it suggests something like “its effects are not actually very large” or “it has some potential risks” would be more appropriate. Grammatically, not factually.
