Medik8 Crystal Retinal 20

Medik8 Crystal Retinal 20 is one of the strongest retinal serums you can buy without a prescription: a 0.2% retinaldehyde night serum for experienced vitamin A users who have completed Crystal Retinal 10 and want results closer to what a clinic would reach for. 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 0.2%, Medik8 Crystal Retinal 20 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.

• Professional-grade strength with Medik8's patented stability, so the retinal is as potent at the end of the tube as the start

• Vegan Society certified, alcohol-free and free from artificial fragrance and synthetic colours

Choose Medik8 Crystal Retinal 20 only once you have finished at least one tube of Crystal Retinal 10; Crystal Retinal 24 is the final step above it.

With more than two decades in specialist skincare and medical aesthetics, Becci - the registered aesthetics nurse behind Adore Your Skin - approaches Medik8 Crystal Retinal 20 the way she would a clinic-strength active: brilliant for the right skin, and only recommended once a client has worked up through the lower strengths. Clients trust her advice because she will say no as readily as yes.

Using your airless pump: Medik8 uses an airless tube system, which keeps the formula protected from air and light right to the last drop. Occasionally, small bubbles of air can become trapped within the product. If it stops dispensing, hold the pump pointing downwards and use your other hand to gently squeeze the bottom of the tube, like a toothpaste tube. Slowly move your hand up the tube while pressing the pump continuously, and the product should start to flow again.
