After cleansing in the evening, apply 2 pumps of Crystal Retinal to the face and neck. Allow to absorb then follow with a moisturiser. It is recommended to use Advanced Night Restore which is specifically designed to be used after vitamin A.
 
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.
 
It is recommendes to use at least 1 tube of your current Crystal Retinal strength before moving up the ladder to the next strength.
