Winner Of Best Retinol Product - Marie Claire Awards 2022!

Ultimate Overnight Vitamin A Serum with 0.1% Stabilised Retinaldehyde

Crystal Retinal™ speeds up cellular turnover and increases the skin’s natural mechanisms for collagen production.

Unlike other forms of retinol, it's formulated with a supercharged derivative of Vitamin A, retinaldehyde. This high-performance, retinaldehyde is an encapsulated active that only requires one conversion to retinoic acid, giving results comparable to clinical grade, and is up to 11x faster in the skin than classic forms of retinol.

Medik8’s crystal encapsulation acts as a time-release mechanism as well as a stability enhancer. Retinaldehyde is encased within a crystal-shaped molecular vehicle that is gradually broken down by the skin’s natural enzymes as the serum is massaged into the skin. This unique action controls the release of the active ingredients to ensure the formula remains stable, absorption is optimised and the highly-potent formula is distributed evenly and consistently throughout the night.

It features a multi-weight hyaluronic acid and vitamin E to hydrate the skin whilst strengthening the skin’s barrier to keep moisture locked in tight. Designed to firm, plump, and resurface skin to visibly minimising fine lines and wrinkles and deliver a healthy, youthful, more even-toned complexion.

Lightweight and luxurious, Crystal Retinal™’s silk-like texture sinks effortlessly into the skin to nurture and restore the complexion.

Great for all skin types including dull, uneven, ageing skin as well as oily, acne skins as it also diminishes P. acnes bacteria which is the bacteria responsible for breakouts.

Key Ingredients:

0.1% Encapsulated Retinaldehyde – Proven to work up to 11 times faster than retinol, retinaldehyde is a revolutionary new form of vitamin A that targets fine lines and wrinkles, pigmentation, and uneven skin texture.

Hyaluronic Acid – With a unique ability to attract and retain more than 1000 times its own weight in water, hyaluronic acid draws moisture from the surrounding atmosphere into the skin, leaving the complexion feeling both nourished and supple.

Vitamin E – An oil-soluble antioxidant, vitamin E can quench free radicals on the skin while stabilising retinaldehyde for optimal power.

Size: 30ml

Directions: After cleansing in the evening, blend a small amount over the face and neck before your regular Medik8 hydrator. Crystal Retinal application should be phased in gradually. Use twice a week for the first 2 weeks, every other day for the next 2 weeks, then every day. Always wear sunscreen during the day.

Precaution: Don't use if pregnant, breast feeding, undergoing skin peeling procedures, on any other vitamin A product, or taking prescription medication for acne.

Start low (application amount) and go slow (frequency of use). On any sign of irritation reduce the frequency of use until the skin acclimates.
