What it is
Retinol is converted in the skin to retinoic acid, which tells cells to renew faster. Over weeks, that can smooth rough texture, soften the look of fine lines and help keep pores clear. It is strong, so most people need to build up slowly.
Benefits
- Smoother texture and more even tone over time
- Softens the look of fine lines
- Helps keep pores from clogging
Watch-outs
- Dryness, flaking and stinging are common in the first weeks ("retinization")
- Makes skin more sensitive to sun, so daily SPF matters
- Usually avoided during pregnancy; ask your doctor
How to use it
Use at night, 2–3 times a week at first, on dry skin. A pea-sized amount covers the whole face. Follow with moisturizer, and wear sunscreen every morning.

- Retinol + Benzoyl PeroxideUse at different timesBenzoyl peroxide can break down some retinoids, and both are drying.
