What is Retinoids and Renewal?
An educational overview of retinoids, one of the most studied skincare ingredient families.
They Work
Retinoids influence skin cell turnover and are studied for their effects on texture, tone, and the appearance of fine lines. They work gradually over weeks to months and are among the most researched topical ingredients in cosmetic dermatology.
Using Them Safely
Start with a low concentration, apply a pea-sized amount in the evening, and use every other night initially. Always pair with daily SPF, as retinoids can increase sensitivity. Reduce frequency if irritation occurs.
