What it is
Retinol is a form of vitamin A. In the skin it is converted, step by step, into retinoic acid, the active form that tells skin cells how to behave. Retinoids as a group have the deepest body of research for treating sun-related aging. Prescription retinoids are the strongest; retinol and retinal are the gentler cosmetic options.
What it does for skin
- Softens fine lines and improves texture over months of steady use.
- Helps even tone and fade sun spots.
- Encourages healthier cell turnover, which can help with clogged pores.
How to use it
