HOW TO USE
Circular Chevron Icon
how to use Zoom In Icon

Step 1

After cleansing in the evening, apply 2 pumps of Crystal Retinal to the face and neck. Allow to absorb then follow with a moisturizer. We recommend Advanced Night Ceramide which is specifically designed to be used after vitamin A (retinoids).

Step 2

For new users of Crystal Retinal, phase application in gradually. Use twice a week for the first 2 weeks, every other night for the next 2 weeks, then every night. You should always use a sunscreen the next morning after using vitamin A.

Crystal Retinal 20 should only be used by those who have comfortably finished at least 2 tubes of Crystal Retinal 10, due to it containing a very high strength of retinal (0.2%).
