Retinoic acid, or clinical-grade vitamin A, is a potent ingredient widely recognised for its ability to combat signs of aging in skincare. While retinoic acid is only available by prescription, retinol products can be purchased over the counter. Crystal Retinal 6, containing retinaldehyde, requires just one conversion to retinoic acid, delivering results up to 11 times faster than traditional retinol products. This active ingredient is expertly encapsulated in a structure that is easily broken down by the skin's enzymes. Sleep with Medik8's Crystal Retinal 6 to experience maximum stability and absorption of vitamin A active, which will gradually release into the skin while minimising irritation. This powerful formula also contains hydrating hyaluronic acid and vitamin E to target fine lines and wrinkles, resulting in smooth and youthful skin. Experience its direct, antibacterial properties as it clears acne and promotes a visibly healthy complexion.

The best!

I bought this as a step up from the Medik8 3. It’s a nice increase in strength, still gentle enough that it won’t peel your whole face off but has great results. I love!
