@lia00372: 3 retinol mistakes I wish I knew sooner! ❗️Not medical advice, I am NOT a dermatologist.❗️1. Don’t use too much! Better to use about 3 dots ( the recommended amount for this serum specifically). 2. Do not start with daily usage. Retinol is an active which can cause irritation if used to frequently without the skin being used to it first. 3. Never skip sunscreen the day after, retinol can make your skin more sensitive to the sun. @celimax.global #celimax #yesstyle #TightenWithRetinol
