Skincare glossary

Retinoids

An umbrella term for vitamin A derivatives (retinol, retinal, and prescription tretinoin) that work in the same direction but differ in strength.

Who it suits
Anyone building tolerance up from retinol toward something stronger.

Why are retinoids used?

If a product lists a “retinoid” rather than plain retinol, it's aiming for a stronger effect on cell turnover and collagen than retinol alone.

Worth knowing

The “best” retinoid isn't the strongest one. It's the one your skin can actually use consistently without irritation.
