What retinol does
Retinol speeds up skin-cell turnover, which can help with texture, fine lines and breakouts over time.
How to start
Low strength, once or twice a week at night, buffered with moisturiser if needed. Increase slowly.
Safety
Wear SPF daily, and avoid layering with strong acids until your skin is used to it.
