After years of careful development, Medik8 took the incredible yet widely undiscovered powers of retinaldehyde and crafted the finished product that reinvented vitamin A skincare forever: Crystal Retinal.

• The more stable the molecule, the more effective it can be on the skin. Crystal Retinal offers a level of retinal stability that is only found at Medik8: our innovative stability system features our renowned crystal encapsulation and a patented formula complex. The dual-layered stability system comes together to protect the retinal molecule for unmatched potency and long-lasting effectiveness.
• After years of careful development, Medik8 took the incredible yet widely undiscovered powers of retinaldehyde and crafted the finished product that reinvented vitamin A skincare forever: Crystal Retinal.
• Stabilised, encapsulated retinal is carefully delivered to the skin within a blend of multi-weight hyaluronic acid, glycerin and vitamin E, to continually infuse the skin with hydration whilst supporting the skin barrier. Our lightweight yet moisturising formula can be used every night of the week (once it has been gradually phased into your routine), as it has been formulated to keep skin comfortable and hydrated whilst reaping the benefits of the powerful retinal molecule.
• Unlike many other forms of vitamin A, including retinol, retinal boasts direct, powerful antibacterial properties, making it the perfect vitamin A molecule for blemish-prone skin.

• Use in the evening. First cleanse, then apply 2 pumps of Crystal Retinal over face and neck. Allow to absorb then follow with a moisturiser. We recommend Advanced Night Restore, designed to be used after vitamin A.
• 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 in the morning while using vitamin A.
• Patch testing prior to use is advised.
• Crystal Retinal 20 should only be used by those who have comfortably finished at least 2 tubes of Crystal Retinal 10, due to it containing a very high strength of retinaldehyde (0.2%).
• Crystal Retinal features in many of our carefully curated regime guides, including our Wrinkle Repair guide. Click the link for additional product recommendations and easy-to-follow layering advice.
• Up to 3 months supply from 1 tube when used daily (after phasing in).

Retinaldehyde

Proven to work up to 11 times faster than retinol[1], retinaldehyde is a revolutionary new form of vitamin A that targets the appearance of fine lines and wrinkles, hyperpigmentation and uneven skin texture.

Hyaluronic Acid

With the ability to attract and retain more than 1,000 times its own weight in water, hyaluronic acid draws moisture into the upper layers of the skin, leaving the complexion feeling hydrated

Glycerin

As a natural humectant, glycerin traps water within the skin to leave it hydrated and comfortable.

Vitamin E

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