We have just the solution.
Meet Oxy-R Peptides, a potent serum that targets visible hyperpigmentation and works effortlessly to promote a more even skin tone.
Formulated with ultra-high concentration (1%) oxyresveratrol in a patented stabilisation system; this powerful brightening technology is one that can only be found at Medik8. Oxyresveratrol (Oxy-R) is an incredibly effective tyrosinase inhibitor - the key enzyme within the skin that produces melanin. Oxyresveratrol works to block the overactivity of tyrosinase, therefore, blocking the overproduction of melanin, which can result in areas of uneven skin tone and dark spots.
A study by The Journal of Biological Chemistry showed Oxy-R to be 33x times more effective tyrosinase-inhibitor than well known hyperpigmentation solution kojic acid.
Uneven Skin Tone? We've Got You
Introducing our targeted solution to hyperpigmentation, new to the peptide family. Oxyresveratrol (Oxy-R) is a gold-standard hyperpigmentation ingredient, stabilised in a Medik8 patented system, at our highest ever dose of 1%.
Incredible Brightening Results
The silky formula is designed to address uneven skin tone, improve the appearance of visible age spots and visibly minimise anti-inflammatory hyperpigmentation from blemishes.
Oxy-R Peptides can be used both morning and night, to further enhance the overall brightening benefits of your CSA regime. CSA = vitamin C + sunscreen by day, vitamin A by night.
While it’s exceptionally powerful, Oxy-R is notoriously difficult to formulate as it is an incredibly unstable ingredient to work with. However, with yet another one-of-a-kind stability innovation, Medik8 have carefully curated a patented system to captivate the unique benefits of ultra-high strength stabilised oxyresveratrol.
Our skincare scientists discovered the perfect solution to bottling Oxy-R’s powers, ensuring that it remains effective from the first drop to the last. Housed in a patented preserversation serum in the lid until it is plunged into the rest of the formula, it uses Click-Activated packaging technology on the first use. Keeping the Oxy-R fresh for 6 weeks, additional patented stabilisers are used, ensuring the formula remains potent until the bottle is finished.
Our Triple Threat To Hyperpigmentation
Oxy-R Peptides offers a triple-threat to hyperpigmentation - combining twin brightening peptides alongside the hero ingredient; Oxyresveratrol.
Works to help block the overproduction of pigment that can lead to visible discolourations and uneven skin tone.
Acetyl glycyl beta-alanine
Works to help stop localised areas of pigment from appearing on the skin.
A gold-standard brightening agent at a previously untouched concentration of 1%, it targets areas of hyperpigmentation, dark spots and improves skin tone.
So, we have our final formula: our star ingredient Oxy-R, two brightening twin-peptides and hyaluronic acid - all combined into a hydrating cocktail that’s ready to target an uneven complexion. Let’s put it to the test.
An independent study with Oxy-R Peptides was conducted on a diverse panel of target customers - all with hyperpigmentation skin concerns. This includes sensitive skins and all skin tones. Participants used Oxy-R Peptides twice a day for 4 weeks, and were asked not to introduce any other new products into their skincare routine during this trial period. Take a look at the remarkable powers of Oxy-R Peptides confirmed by the study…
Clinically proven to significantly improve the look of even tone in 8 weeks*
Skin appears visibly brighter after using Oxy-R Peptides for just 7 days*
The appearance of dark spots are faded after just one month*
92% found Oxy-R Peptides to be gentle on their skin
*Proven via independent consumer study conducted over 4 weeks on 52 participants with sensitive skin.
Post-inflammatory hyperpigmentation is particularly common in deeper skin tones, fitzpatricks 4-6. All fitzpatrick skin types have similar numbers of melanin-making melanocyte cells, however these cells are more active and produce more melanin in deeper fitzpatricks.
Therefore, we specifically tested the serum on a larger sample of fitzpatricks 3-6, due to the larger concern of hyperpigmentation within these skin tones. With gentle power, we found that Oxy-R Peptides has the ability to visibly brighten the appearance of deeper skin tones; improving the overall appearance of hyperpigmentation across the complexion.***
Oxy-R Peptides can be used in both morning and evening skincare routines, to target areas of hyperpigmentation and enhance the overall brightening benefits of vitamin C and A products. Oxy-R Peptides is suitable for all skin types, including sensitive skins.**
A CSA-booster, Oxy-R Peptides is an integral part of any Medik8 CSA routine for an optimal targeted treatment for hyperpigmentation.
Sunscreen is the most important factor in helping to prevent the development of hyperpigmentation. It works to block our skin from the damaging UV rays that trigger the overproduction of melanin, and it must be used with Oxy-R Peptides to help improve the appearance of hyperpigmentation.
Avoiding the sun, wearing a high-protection SPF and vitamin C while using Oxy-R Peptides is key to helping to prevent hyperpigmentation in your daily routine. As both ingredients are antioxidants, oxyresveratrol and vitamin C work in synergy to prevent oxidation via free radicals, therefore helping to block melanin production. We also recommend using vitamin A at night to promote cellular turnover, which helps to disperse areas of localised hyperpigmentation and sheds away cells with extra melanin; returning skin shade to baseline.
Complementary to Even Peel
You can enjoy Oxy-R Peptides at home, or as part of an Even Peel course in clinic for accelerated hyperpigmentation results.
A perfect pair. Ask your Medik8 professional today.
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.
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 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 suitable for all skin types, including sensitive skins. Oxyresveratrol is known to be non-irritating and non-sensitising on skin.
Oxy-R Peptides is a booster product for CSA routines; it can work to enhance and accelerate the visible skin brightening results. We recommend vitamin C during the day for all-round 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 really target areas of hyperpigmentation and enhance the overall brightening benefits of vitamin C and A products.
Yes, our Peptides Family can be used together. They are perfect additions to CSA routines, to enhance skin benefits. They are also ideal to target specific skin concerns, for example, Oxy-R Peptides for hyperpigmentation, Clarity Peptides for congested skin types or Liquid Peptides for visible signs of skin ageing. They can be used in conjunction with one another to address multiple skin concerns at once.
Unfortunately, as a cosmetic brand we are unable to provide specific medical advice relating to our products.
