Summary

Tretinoin, a potent Vitamin A derivative, has historically been prescribed as a medical treatment for skin conditions like acne due to its ability to increase cellular turnover. This same mechanism is now increasingly utilized for healthspan optimization, specifically to reverse the structural damage caused by sun exposure, known as photoaging. By stimulating new collagen production and preventing the breakdown of existing stores, it effectively reduces fine lines and preserves the skin's long-term structural integrity and function.

Purpose

Stimulates skin cell turnover and collagen production to reverse photoaging.
