Celimax The VITA-A Retinal Shot Tightening Booster 15ml

A concentrated retinal booster in a small 15ml bottle, for firmness and the look of fine lines. Retinal is a retinoid: start with two nights a week, always at night, always with sunscreen the next morning, and build up only if your skin stays comfortable.

If your skin is melanin-rich, go slower rather than stronger. Irritation is what triggers dark marks, so a product bought to smooth and firm can leave pigmentation behind if it is pushed too hard, too fast. A higher percentage is not an upgrade.
