Retinol, Explained Without the Fear

The most effective ingredient in skincare is also the most misunderstood. Here is what actually happens on your skin.

Retinol speeds up cell turnover and signals collagen production, which is why it helps with texture, fine lines and post-acne marks over time. The purging and irritation people associate with it almost always comes down to starting too strong, too often. Two nights a week, a pea-sized amount, moisturizer after. Build from there. Consistency at a low dose beats intensity you cannot sustain.
