Medik8 has long been considered royalty of the retinal world, and its supercharged Crystal Retinal 20 (30ml) takes the brand's reign to new, skin-smoothing heights...

This silky night serum for retinal regulars contains the strongest concentration of vitamin A to come out of the Crystal collection to date (that's a potent 2.0% retinaldehyde for all the skingredient buffs out there). Expect a complexion that appears smoother, brighter and oh-so-supple. That's not all though: the addition of hyaluronic acid, vitamin E and glycerin provides a soothing and hydrating pick-me-up to ensure that this super serum is gentle to even sensitive skin types.

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 moisturiser. We recommend Advanced Night Restore which is specifically designed to be used after vitamin A.

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%).

Making skin care simple, Medik8 takes the fuss out of caring for your complexion. Powered by three key ingredients: vitamin C, vitamin A and non-negotiable SPF, the brand's signature skin care saviours are famed for their potent potions. Meet: Crystal Retinal 20 (30ml). This vitamin A-packed serum is the key to a more radiant looking complexion.
