What is Tretinoin?
Tretinoin (all-trans retinoic acid or ATRA) is a powerful Vitamin A derivative that’s stronger and more effective than retinol. It encourages skin cell turnover, stimulates collagen and elastin production, and helps skin look brighter and more youthful. It’s also effective for treating mild to moderate acne.
If you have sensitive skin, start with lower concentrations to avoid irritation. Defy Medical offers access to three formulas based on skin sensitivity: sensitive, mild, and strong.
