Introducing Medik8's NEW Serum: Oxy-R Peptides

A new, exciting addition to Medik8's ever-growing peptide family has just landed!

Medik8's brand new Oxy-R Peptides is a CSR booster offering a targeted solution to hyperpigmentation.

With stabilised high strength Oxy-R technology, oxyresvertrol (Oxy-R) is a gold-standard hyperpigmentation ingredient, stabilised in Medik8 patented system, at their highest ever dose of 1% and a triple threat to Hyperpigmentation!

Plus, Oxy-R Peptides features two brightening twin peptides which boost the action of oxy-R.

What is Oxyresvertrol?

Oxy-R is a renowned brightening substance derived from the Mulberry plant family.

A powerful, effective, and fast-acting brightening agent to target dark spots, areas of hyperpigmentation, or post-inflammatory pigmentation.

Tyrosinase is the main enzyme responsible for creating melanin in the skin. Oxy-R helps to block its action, resulting in a visibly brighter skin, more even toned in areas of hyperpigmentation.

Oxy-R is also a Potent Antioxidant

Antioxidant oxyresveratrol can block the formation of free radicals to stop them from triggering the overproduction of melanin.


A peptide that works to interrupt the pathways that lead to discolouration and uneven skin tone.

Acetylglycyl Beta-alanine:

Works to stop the transport of melanin to the keratinocyte where the overproduction of pigment becomes visible on the skin.

Why are the Oxy-R Peptides different from others on the market?


  • Exceptionally powerful
  • One of a kind stability innovation to fight the fact that Oxy-R is an incredibly unstable ingredient
  • Patented system
  • Oxy-R stored in the lid
  • Click-activated packaging technology

More about Oxy-R Peptides

  • Oxy-R Peptides is a lightweight serum with a silky texture. It absorbs quickly into the skin, ready for the next steps of your regime.

  • It is suitable for all skin types, including sensitive skins.

  • Oxyresveratrol is naturally brown once active in water - so once the packaging has been "click activated" and the Oxy-R is plunged into the water-based solution, the serum will come to a deep brown colour.

  • Oxy-R Peptides will not make your skin more sensitive to the sun and is perfect for use in both morning and evening routines to boost your CSA routine. We always recommend using sunscreen during the day to protect your skin from sun damage.

  • Oxy-R Peptides is a booster product for CSA routines; it can work to enhance and accelerate the visible skin brightening results. Medik8 recommends vitamin C during the day for all-around skin radiance and antioxidant protection, and vitamin A at night to promote cellular turnover to result in a more visibly even tone.

  • Oxy-R Peptides can be used in both morning and evening routines, to target areas of hyperpigmentation and enhance the overall brightening benefits of vitamin C and A products.
