HOW TO USE

First-time use

If you're new to Crystal Retinal we recommend a patch test at least 24 hours before first use. Learn how to patch test here.

Phase application in gradually. Use twice a week for the first 2 weeks, every other night for the next 2 weeks, then every night.

Step 1

After cleansing in the evening, apply 2 pumps of Crystal Retinal to the face and neck. Allow to absorb.

Step 2

Follow with a moisturiser. We recommend Advanced Night Restore which is engineered to be used after vitamin A (retinoids).

Step 3

Always use a sunscreen the next morning after using vitamin A. We recommend Advanced Day Ultimate Protect.

NOTE

We recommend using at least 1 tube of your current Crystal Retinal strength before moving up the ladder to the next strength.
