Vitamin A and Antiaging
In the study to evaluate the effectiveness of topical retinol (vitamin A) in improving the clinical signs of naturally aged skin, Dr. Kafi R, and the research team at the University of Michigan Medical School, showed that topical retinol improves fine wrinkles associated with natural aging. Significant induction of glycosaminoglycan, which is known to retain substantial water, and increased collagen production are most likely responsible for wrinkle effacement. With greater skin matrix synthesis, retinol-treated aged skin is more likely to withstand skin injury and ulcer formation along with improved appearance(3).
