Rediscover more youthful skin with Medik8 Crystal Retinal 6.

This serum delivers next-generation results using encapsulated Retinal so that it releases slowly into the skin.

This serum targets lines and wrinkles, uneven tone, hyperpigmentation and rough texture. It may also reduce buildup and associated bacteria in the pores.

Why Medik8 Crystal Retinal 6?

Retinal is a superior type of topical Vitamin A. It only requires one conversion step in the skin to become Retinoic Acid, the active form recognised and utilised by the skin. Retinol requires two conversion steps.

Medik8 Crystal Retinal 6 is a high-strength formulation that delivers results while minimising side effects.

Put simply, Retinal sits somewhere between Retinol and prescription Tretinoin.

Retinal has been clinically shown to work faster and deliver enhanced results, without being any more irritating than Retinol.

Medik8 Crystal Retinal 6 ingredients

The key ingredients in Medik8 Crystal Retinal 6 are:

Retinal (Retinaldehyde) is  used in an encapsulated form at a concentration of 0.06%. Retinal is an advanced form of Retinal that’s proven to work  up to 11 times faster than Retinol. It’s been found to be effective in improving the look of fine lines and wrinkles, pigmentation, uneven tone and rough texture. Retinal has direct antibacterial properties, which also makes it helpful for those prone to breakouts.

Hyaluronic Acid has a unique ability to attract and retain up to 1000 times its own weight in water. This ingredient draws moisture from the surrounding atmosphere and draws it into the skin. Skin feels and looks more plump and supple.

Vitamin E is a remarkable and reliable antioxidant that counters free radicals and reduces their ability to damage the skin. It also helps stabilise the Retinal so that it retains its potency longer.

Tetrahexyldecyl Ascorbate is a new generation of Vitamin C that has exceptional stability and better penetration than L’Ascorbic Acid. It provides antioxidant protection against UVB and UVA rays, increases collagen synthesis and reduces  melanogenesis in skin cell cultures by more than 80%, meaning it brightens the skin’s appearance.

Glycerin is a natural humectant that traps water in the skin. It helps to hydrate and keep the skin feeling comfortable.

Squalane provides skin-identical hydration and creates a softer, smoother complexion. It  also helps reduce blemish-causing bacteria and keep it clearer.


  • Skin appears younger and fine lines and wrinkles are less visible.
  • Look of uneven tone and pigmentation is improved.
  • Skin feels softer and smoother.
  • Complexion looks more radiant.

Perfect pairs

Pair at night with the Medik8 Hydr8 B5 Intense. Hyaluronic Acid soothes the skin and helps offset any dryness and irritation caused by retinoids. Apply the Medik8 B5 Hydra Intense before the Retinal.

In the morning, use the BioBare Vitamin C B E & Ferulic Serum to enhance your results.

Medik8 Crystal Retinal Review

The difference between using Medik8 on my skin has been astounding. This retinol is .. wow. Genuinely noticing improvements in my skin texture and appearance. Word of caution, though, do not overuse it and introduce it gently otherwise it will sensitise the skin. Patience is very much key with this product. I’m still only using it max twice a week, and happy to continue for the foreseeable future because that’s what my skin can tolerate — and it’s still working!


How to use

Apply Medik8 Crystal Retinal 6 after cleansing at night. Massage a small amount across the face, neck and décolletage. Allow to absorb before applying your moisturiser.

The application of Crystal Retinal 6 should be phased in gradually. Use twice a week for the first 2 weeks, every second  night for the next 2 weeks and then every night, or according to your skin’s tolerance.

This is a potent Retinal. Do not push the limits of your skin. You will still get results, even if you’re not using it nightly.

Always wear a high SPF broad-spectrum sunscreen during the day when using this product and for one week after.

Warning: Do not use if pregnant or breast-feeding.
