Medik8's Crystal Retinal 1 Serum is an innovative overnight treatment that contains a specialist crystal-encapsulated form of 0.01% Retinaldehyde, which is quicker and easier for the skin to convert into Retinoic Acid, getting to work up to 11 times faster than standard Retinol. This very mild concentration is perfect for those new to the ingredient and anyone with sensitive skin. It effectively boosts collagen production, smoothes uneven texture, and contains natural antibacterial properties to help minimise breakouts. Added Hyaluronic Acid and Vitamin E hydrate and repair the skin, while specialist time-release technology ensures skin experiences minimal irritation.

After cleansing in the evening, massage a small amount into the face and neck. Follow with your usual moisturiser. To being with, use twice a week for around two weeks then gradually increase the frequency of application.

The Crystal Retinal range is ideal for those wanting to step up from standard Retinol but who aren't ready for the r-Retinoate range.

PATCH TEST

If you are new to this product or any of its ingredients, we recommend completing a patch test first.

USE OF RETINOL

When using Retinol for the first time, it is important to allow the skin time to acclimatise to the active ingredient. Apply a small amount in the evening no more than twice a week, never on consecutive evenings, for at least two weeks. If the skin hasn’t suffered any extreme irritation or redness, start to increase the number of applications gradually over a period of weeks until you reach a number your skin is comfortable with. This could range from three nights to seven nights a week.

As Retinol can make the skin sensitive to sunlight, always apply a sunscreen to the skin every morning to prevent sun-induced inflammation and damage.
