Clinical Trial Summary

The purpose of this study is to asses the impact of topically applying a form of vitamin C known as tetrahexyldecyl Ascorbate (THDA) along with a novel anti-aging ingredient, acetyl zingerone, compared against applying THDA alone.

Description:

In this study, we examine the effects of adding acetyl zingerone to vitamin-C derived ester THDA on its effects on the signs of photoaging (redness, uneven skin tone, and the appearance of fine lines) and compare it to the effects of applying THDA alone.

Acetyl zingerone is derived from ginger and has anti-oxidant properties

In this study, participants will be randomized to either receiving a THDA + acetyl zingerone product or a THDA only product.

This means that you will have an equal chance of receiving either product. You and the research team will not know which product you have been randomized to received because the products will be labelled with a code. The research team will only know which product contained THDA + acetyl zingerone and which product contained only THDA at the end of the study.
