Medik8 Crystal Retinal 6

Medik8 Crystal Retinal 6 is the strength Medik8 put through independent clinical testing: a 0.06% retinaldehyde night serum for regular vitamin A users that was shown to reduce the appearance of wrinkles by 20% in 12 weeks, with 100% of participants finding it gentle on their skin. Crystal Retinal is the No.1 retinal serum worldwide, and every strength shares the same patented stability system, so the retinal stays potent until the last pump.

Retinaldehyde is the form of vitamin A one step closer to retinoic acid than retinol, which is why it works up to 11 times faster. At 0.06%, Medik8 Crystal Retinal 6 targets the appearance of fine lines and wrinkles, dark spots, uneven texture and loss of firmness, while hyaluronic acid, glycerin and squalane keep skin comfortable and vitamin E adds antioxidant support. Medik8 reports visible improvement in wrinkles, smoothness and brightness in as little as 7 days, and the range's clinical study on Crystal Retinal 6 found a 20% reduction in the appearance of wrinkles over 12 weeks.

Choose Medik8 Crystal Retinal 6 if you already use vitamin A comfortably or have finished a tube of Crystal Retinal 3; once a full tube has gone well, Crystal Retinal 10 is the next step.

After more than two decades in specialist skincare and medical aesthetics, Becci - the aesthetics nurse who founded Adore Your Skin - still recommends more tubes of Medik8 Crystal Retinal 6 than any other retinal. It is the strength with the clinical numbers behind it, and the one she suggests to clients who want honest, measurable change rather than a marketing promise.
