New Brand: Alpha-H
Alpha H skincare is known for high-performance formulas that target concerns like dullness, fine lines and uneven texture, helping you achieve clearer, smoother, and more radiant skin.
This groundbreaking cream-serum uses a powerful retinaldehyde formula to dramatically improve the visible signs of ageing.
Medik8 Crystal Retinal 1 is Medik8's entry-level gentle-strength vitamin A, ideal for those who have really sensitive skin or are looking to incorporate a low strength but highly effective vitamin A serum in their routine.
Revealing younger-looking skin with just one tube*, this ground-breaking cream-serum is formulated with 0.01% Retinaldehyde, a super-charged derivative of vitamin A, which works to promote the skin's natural collagen production, rebuild lost collagen and increase cell turnover, promoting a smoother, brighter and healthier complexion.
By requiring only one conversion to retinoic acid, the Crystal Retinal™ is clinically proven to work 11xfaster than other forms of retinol*, visibly smoothing, brightening, and firming to deliver results comparable to clinical-grade vitamin A.
Trials have shown that in as little as four weeks, 97% of users felt that their skin had a more youthful appearance* resulting in a 20% reduction in visible hyperpigmentation*, a 20% reduction in the appearance of wrinkles*, and an 11% increase in skin firmness* with continued use.
With the innovative crystal encapsulation system, the Retinaldehyde is slowly time-released, helping to reduce irritation, making this suitable for all skin types, including those who have previously been sensitive to Retinol.
Recommended by dermatologists and professionals worldwide, this retinal is part of a unique ladder of five progressive strengths, providing ever-improving benefits that combat even the most stubborn fine lines, wrinkles, and dark spots.
With other key ingredients including Hyaluronic Acid and Vitamin E, the skin is hydrated at every level, leading to a plumper and smoother complexion and the skin barrier is strengthened, helping to lock in moisture. With a lightweight, silk-like texture that absorbs quickly into the skin, this powerful serum renews and resurfaces the skin, visibly minimises fine lines and wrinkles, reduces blemishes and pigmentation and delivers a healthier, brighter and more even-toned complexion.
Clinically proven to deliver exceptional results, this dermatologist-recommended retinal is free from artificial fragrance, synthetic colours, parabens, and alcohol.

Benefits of Medik8 Crystal Retinal 1:
How to use:
Step 1: After cleansing in the evening, apply 2 pumps of Crystal Retinal to the face and neck. Allow to absorb then follow with a moisturiser. We recommend Advanced Night Restore which is specifically designed to be used after vitamin A.
Step 2: For new users of Crystal Retinal, phase application in gradually. Use twice a week for the first 2 weeks, every other night for the next 2 weeks, then every night. You should always use a sunscreen the next morning after using vitamin A.
Note: Ladder up your visible age-defying results over time with Crystal Retinal's 5 progressive strengths (0.01% - 0.1% retinaldehyde) - only available at Medik8. For those with very sensitive skin, we recommend starting with Crystal Retinal 1 (0.01%). However, most Crystal Retinal and vitamin A beginners start on Crystal Retinal 3 (0.03%). If you're an experienced vitamin A user already, start at Crystal Retinal 6 (0.06%) before working your way up to Crystal Retinal 10 (0.1%) & Crystal Retinal 20 (0.2%).
Always use a sunscreen during the day in conjuncture with this product.
Not to be used if pregnant or breastfeeding.
Size: 30ml
Please Note: This product cannot be shipped outside of the UK and Ireland.
