What Is Retinol? (Beginner-Friendly Explanation)

Retinol is a vitamin A derivative that boosts cell turnover and increases collagen production. This is why it’s effective for wrinkles, acne, pigmentation, and texture.

Beginners often experience irritation because the skin barrier needs time to adapt to the increased turnover. That’s why it’s essential to start slowly and use the correct strength.

Which Retinol Should Beginners Use?

Best beginner strengths (0.1%–0.3%)

0.1% for sensitive skin
0.2%–0.3% for normal/combination skin

Recommended beginner retinols:

Gel vs Cream vs Serum — which is safest?

Cream = best for beginners (more hydrating)

Products mixed with AHAs/BHAs

The 1-2-3 Retinol Rule (Beginner Routine)

How to Use Retinol Step-by-Step
