Tetra-isopalmitoyl ascorbic acid (VC-IP), an oil-soluble vitamin C derivative, is known to be effective for treating photoaging skin caused by oxidative stress.

In addition, it is known that morphological changes of the skin occur on the face with aging, and the main cause has been reported to be photoaging.

There have not been any published reports that examined the clinical effects of vitamin C derivatives on periorbital wrinkles.

The purpose of this study was to characterize the potential anti-wrinkle effect of VC-IP.

A double-blind, randomized, placebo-controlled, split face clinical trial was performed on 3 groups of 23 female subjects each who used 1%, 2%, or 3% VC-IP creams versus a placebo cream to treat their facial wrinkles.

VC-IP cream was applied on the periorbital area on one side of the face of each subject twice a day for 8 weeks and a placebo cream was applied on the other side.

Anti-wrinkle effects were evaluated by visual wrinkle grading and topographic assessments.
