After cleansing in the evening, apply 2 pumps of Medik8 Crystal Retinal 1 Night Serum 30ml to the skin of the face and neck, avoiding the eye contour area. Then, gently massage the skin and allow the product to absorb. Finally, follow with a moisturizer, preferably the brand's Advanced Night Restore. In the morning, always wear sunscreen.
For new users of Crystal Retinal, start with the appropriate strength and gradually build up the application frequency. This helps your skin build up tolerance while avoiding any potential irritation. So, use the product twice a week for the first 2 weeks, every other night for the next 2 weeks, and then every night. Once your skin has adjusted and built tolerance, if you desire, you can move on to the next strength. When moving up within the Crystal Retinal ladder, there’s no need to phase in, but it's recommended to complete at least 1 tube of the previous strength before advancing to the next strength.
