Use in the evening after cleansing, toner and compatible treatment serums.

Apply 2 pumps evenly over the face and neck and allow to absorb before following with moisturiser. Medik8 recommends following Crystal Retinal with a moisturiser such as Advanced Night Restore.

Crystal Retinal 24 should only be introduced after completing at least one full tube of Crystal Retinal 20. During the first two weeks, closely monitor skin tolerance. If sensitivity develops, reduce the quantity applied or begin using the product every other evening.

Apply a high-protection broad-spectrum sunscreen every morning. Do not apply directly around the eye area; use a dedicated eye-area Vitamin A formula instead.

The higher retinal concentration gives Crystal Retinal 24 a noticeable peach colour. Allow the product to fully absorb before contact with light-coloured bedding or clothing and follow with moisturiser to help seal the formula into the skin.

Medik8 generally recommends avoiding Vitamin A during pregnancy and breastfeeding and discussing skincare ingredients with a GP or midwife where appropriate.
