✓ 1% Oxyresveratrol | ✓ Visible Results in 7 Days | ✓ Proven on All Skin Tones

Medik8 Oxy-R Peptides – The professional-strength dark spot serum that delivers visible brightening results in just 7 days, powered by an exclusive concentration of oxyresveratrol you won't find anywhere else.

This breakthrough formula harnesses 1% oxyresveratrol – a gold-standard brightening ingredient that's 33x more effective than kojic acid at inhibiting tyrosinase, the enzyme responsible for melanin production. The problem? Oxyresveratrol is notoriously unstable and loses potency rapidly when exposed to light, heat and air. Most brands can't even formulate with it. Medik8 solved this with their patented click-activated stabilisation system, storing the active ingredient in the bottle lid until you're ready to use it.

The result is a triple-threat approach to hyperpigmentation: oxyresveratrol blocks melanin formation, while twin brightening peptides (Tetrapeptide-30 and Acetyl Glycyl Beta-Alanine) work synergistically to prevent pigment transport to the skin's surface. Clinically proven on all skin tones including Fitzpatrick 5-6, this lightweight serum absorbs instantly and slots seamlessly into any existing routine – morning, evening, or both.

No hydroquinone = effective brightening without controversial ingredients
Non-photosensitising = safe to use morning and evening without increased sun sensitivity
Proven on deeper skin tones = specifically tested where hyperpigmentation concerns are most prevalent

Best For

Anyone struggling with dark spots, age spots or sun damage

FAQS

What makes Oxy-R Peptides different from other brightening serums? +

Three key differentiators set this apart:

The 1% oxyresveratrol concentration is exclusive to Medik8 – most brands can't stabilise this ingredient at all, let alone at this strength
The patented click-activated packaging keeps the formula potent until you're ready to use it, then maintains stability for 6 weeks
The triple-action approach (oxyresveratrol + twin peptides) attacks pigmentation at multiple stages of the melanin production pathway

Independent research published in The Journal of Biological Chemistry found oxyresveratrol to be 33x more effective as a tyrosinase inhibitor than kojic acid.

Will this work on my skin tone? +

Yes – Oxy-R Peptides has been clinically proven on all skin tones, with 33% of test panels specifically including Fitzpatrick 5-6 (deeper complexions) where dark spots are often more prevalent and visible.

The formula is designed to target excess melanin production without affecting your natural skin colour, making it suitable for anyone dealing with hyperpigmentation regardless of their baseline tone.

When will I see results? +

Based on independent clinical studies:

7 days: Skin appears visibly brighter
4 weeks: Dark spots appear faded
8 weeks: Significantly improved even tone

Results vary depending on the depth and age of pigmentation. Surface-level spots (like recent post-acne marks) typically respond faster than deep-set age spots or melasma.

Can I use this with my vitamin C and retinol? +

Absolutely – in fact, Medik8 recommends it. Oxy-R Peptides is designed as a CSA booster that enhances your existing routine:

Morning: Apply Oxy-R Peptides, then vitamin C serum, then SPF
Evening: Apply Oxy-R Peptides, then vitamin A (retinal/retinol), then moisturiser

As antioxidants, oxyresveratrol and vitamin C work synergistically to block melanin production. Vitamin A promotes cellular turnover, helping to shed pigmented cells faster.

Is it suitable for sensitive skin? +

Yes – oxyresveratrol is known to be non-irritating and non-sensitising. In clinical testing, 92% of participants agreed Oxy-R Peptides was gentle on their skin, including those with sensitive skin types.

The formula also won't make your skin more sensitive to the sun (unlike some brightening acids), though you should always use SPF to prevent new pigmentation from forming.

Why does my serum turn brown after activation? +

This is completely normal. Oxyresveratrol is naturally brown when dissolved in water, so once you click-activate the packaging and the active ingredient combines with the water-based solution, the serum takes on a deep brown colour.

This colour change actually confirms the formula is properly activated and at full strength.
