Go from before to after 11x faster. The Medik8 Crystal Retinal revelation that leaves ordinary vitamin A behind.

Patented Stability Matters

The more stable the molecule, the more effective it can be on the skin. Crystal Retinal offers a level of retinal stability found only at Medik8. Our innovative stability system features our renowned crystal encapsulation and a patented formula. The dual-layered stability system comes together to protect the retinal molecule for unmatched potency and long-lasting effectiveness.

Renew your complexion with a science-backed biomimetic formulation that is clinically proven to provide incredible age-defying results. Internationally patented, the breakthrough formula promotes visibly brighter, firmer and smoother-looking skin in just one tube. 

Crystal Retinal yields potent results by harnessing our innovative encapsulated technology to isolate our retinoid from interacting with other ingredients. Its protective liposomal barrier helps to prevent diluting its efficacy or altering its pH balance and gives you results you can count on. 

Minimise Irritation For Maximum Results

High-active skincare doesn’t mean making compromises. As one of the strongest retinoids you can access without a prescription, Crystal Retinal is one step away from converting into retinoic acid in the skin. While it's stronger and works quicker to address the appearance of ageing skin, Crystal Retinal is more easily tolerated by most skin types.

With a time-release formula that’s aided by our unique, stabilised and encapsulated technology, Crystal Retinal works throughout the night to minimise the chances of irritation and ensure you can enjoy the strongest and gentlest high vitamin A cream available.

Ladder Up

Always peak, never plateau. Ladder up your results with 5 available strengths: 1, 3, 6, 10 and 20. 

Our Crystal Retinal 1 is the best introduction for people with sensitive skin types, but most customers start on Crystal Retinal 3 (for skincare beginners) or 6 (for experienced skincare users). Once you’ve acclimatised to its powerful formula, move up to 10. Find out which level of Crystal Retinal is right for you.

Top tip! Crystal Retinal is also the perfect vitamin A for those wanting to target the appearance of blemishes and congestion due to retinal’s unique antibacterial action on the skin.

More Benefits, Cumulative Results

Never a one-hit-wonder — Crystal Retinal offers a long lineup of benefits to reward your skin with consistent use. While most people reach for it to improve the firmness of their skin, it doubles as an age prevention tool as much as an age maintenance treatment to manage the look of fine lines and wrinkles.

While helping to increase the turnover of your skin cells, Crystal Retinal has been shown to decongest pores to improve skin texture and luminosity and help manage hyperpigmentation concerns to even out skin tone. By constantly replenishing your skin with newer cells, Crystal Retinal can help you manage open and closed comedones to improve the look of blemishes on your skin.

With multiple benefits in one product, Crystal Retinal has become a skincare cult favourite, winning countless awards.

  • ​​​ ​​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.

Hear from the experts

“After years of research and experimentation, we cracked the retinal code in 2018 with a unique stabilisation discovery. Our reinforced stability system involves two formulation techniques. First, we protected the powerful yet fragile molecule with a crystal encapsulation that works to both blanket the retinal and time-release it onto our skin gradually throughout the night to minimise any potential for irritation. We then fortified this with a patent-pending stabilisation formula complex, which is unique to Medik8, to ensure the retinal is stabilised throughout its whole life cycle - from raw material, all the way onto our skin. This means that your Crystal Retinal remains powerful from the first application, to the very last".
