Crystal Retinal 20 contains a very high strength of retinaldehyde (0.2%) and should only be used if you have comfortably finished at least two tubes of Crystal Retinal 10.
Formulated with Medik8’s highest-ever strength of 0.2% encapsulated retinaldehyde – a powerful derivative of Vitamin A – Medik8 Crystal Retinal 20 is the ideal solution for those with skin suited to stronger Vitamin A formulations, revealing younger-looking skin with just one tube.
Medik8 Crystal Retinal 20 is a high-performance night serum for those looking to boost the results of Crystal Retinal 10. Before purchasing Crystal Retinal 20, users should be comfortably applying Crystal Retinal 10 every night for 3 months or completed 2 full tubes before considering moving up to Crystal Retinal 20.
Formulated with a globally patented system that ensures maximum potency and efficacy, this serum provides gentle yet effective results even on the most sensitive skin.
Recommended by dermatologists and professionals worldwide, this clinically proven serum has a host of skincare benefits, tackling even the most stubborn lines and deep-set wrinkles to reveal radiant, youthful skin.
Smoothing stubborn lines in just seven days*, this serum is revered by its users, providing a 20% reduction in the appearance of wrinkles*, a 20% reduction in visible hyperpigmentation, and an 11% increase in skin firmness.
Medik8’s innovative Crystal Retinal technology works 11 x faster than other forms of retinol*, delivering results comparable to clinical-grade Vitamin A. Retinaldehyde has also been proven to be 2.8 x more biologically active than retinol. In addition, retinaldehyde delivers powerful antibacterial properties, ideal for targeting blemish-causing bacteria for visibly clearer skin.
With double the concentration comes double the results. More retinal equals more power, thanks to Medik8’s innovative Double-Layered Stabilisation System. In addition to the active 0.2% Retinaldehyde, Medik8 Crystal Retinal 20 also contains hydrating Hyaluronic Acid, antioxidant Vitamin E and natural humectant, Glycerin.

Benefits of Medik8 Crystal Retinal 20:
How to use:
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.
Note: Ladder up your visible age-defying results over time with Crystal Retinal's 5 progressive strengths (0.01% - 0.1% retinaldehyde) - only available at Medik8. For those with very sensitive skin, we recommend starting with Crystal Retinal 1 (0.01%). However, most Crystal Retinal and vitamin A beginners start on Crystal Retinal 3 (0.03%). If you're an experienced vitamin A user already, start at Crystal Retinal 6 (0.06%) before working your way up to Crystal Retinal 10 (0.1%) & Crystal Retinal 20 (0.2%).
Size: 30ml
Please Note: This product cannot be shipped outside of the UK or Ireland.
