Topical application of palmitoyl-RGD reduces human facial wrinkle formation in Korean women.

Maintaining a youthful appearance is a common desire among the aging population. Loss of elasticity and dermal density constitutes major causes of wrinkle formation during skin aging. In particular, periorbital wrinkles comprise the critical assessment point of skin aging.

Effects of palmitoyl-KVK-L-ascorbic acid on skin wrinkles and pigmentation.

Wrinkle formation and abnormal pigmentation are major clinical alterations associated with skin aging. As the aim of our study was to investigate the effects of palmitoyl-KVK-L-ascorbic acid on skin aging, the anti-wrinkle and depigmentation effects of palmitoyl-KVK-L-ascorbic acid were evaluated by measuring collagen expression in dermal fibroblast cells and inhibition of melanogenesis in B16F1 cells, respectively. The anti-aging effect of palmitoyl-KVK-L-ascorbic acid cream was also evaluated against a placebo cream in a clinical trial.
