High-Strength Oxyresveratrol Brightening Peptide Serum. Medik8’s targeted solution to hyperpigmentation.

The Medik8 Oxy-R Peptides serum targets hyperpigmentation with a high concentration of oxyresveratrol in a unique stabilisation system. Formulated for all skin types, including sensitive skin, this serum effectively improves the appearance of age spots, uneven skin tones, and post-inflammatory hyperpigmentation. Significant fading of dark spots is noticeable after only 4 weeks of use.

Medik8 Oxy-R Peptides is suitable for all skin types and tones, including those with sensitive skin types. Medik8 Oxy-R Peptides is best suited to those who are concerned with uneven skin tone or hyperpigmentation, including those with post-inflammatory pigmentation concerns (aka pigmentation scarring from blemishes, etc).

Medik8 Oxy-R Peptides is suitable for use during pregnancy or when breastfeeding.


Oxy-R Peptides effectively utilises the renowned brightening agent oxyresveratrol, at a concentrated 1% level. A potent but gentle antioxidant, Oxy-R specifically targets areas of hyperpigmentation, dark spots and post-inflammatory pigmentation. Studies have shown it to be 33x more efficient than kojic acid, working by blocking the function of tyrosinase - the primary enzyme that produces pigment in the skin.

Despite its impressive potency, Oxy-R is known for being a highly volatile ingredient. To address this, Medik8 has pioneered a patented system to preserve and harness the powerful benefits of ultra-high strength stabilised oxyresveratrol. By storing the 1% Oxy-R in a specially designed preservation serum within the lid, the innovative Click-Activated packaging technology ensures the formula maintains its stability from activation to the very last drop.

Oxy-R Peptides is a powerful solution for hyperpigmentation, utilising two brightening peptides and Oxy-R to enhance the skin's visible tone. Tetrapeptide-30 effectively prevents the overproduction of pigment, reducing the risk of discolourations and uneven skin tone, while acetyl glycyl beta-alanine prevents localised areas of pigmentation from developing.

Key Ingredients 

1% Oxyresveratrol (Oxy-R) one of the most powerful skin brightening agents available in skincare, which is naturally derived from the mulberry family. It helps to block the action of tyrosinase, to transform dull, uneven skin tones.
Tetrapeptide-30 an illuminating peptide that helps to minimise the production of tyrosinase, to block the overproduction of melanin.
 Acetyl Glycyl Beta-Alanine a brightening peptide solution that works to help block the transport of melanin to the skin cell, where the overproduction of pigment becomes visible on the skin.
Hyaluronic acid with a unique ability to attract and retain more than 1,000 times its own weight in water, hyaluronic acid draws moisture from the surrounding atmosphere into the skin, leaving the complexion feeling both nourished and supple.

Aqua (Water), Butylene Glycol, Artocarpus Lakoocha Wood Extract, Gluconolactone, Acetyl Glycyl Beta-Alanine, Glycerin, Lactic Acid, Sodium Benzoate, Disodium Edta, Sodium Hyaluronate, Xanthan Gum, Calcium Gluconate, Sodium Metabisulfite, Tetrapeptide-30, Hydroxyresveratrol.

We believe in the right product for the right person. We want our product information to be useful to you, so we have done our best to provide you with the most up to date ingredients list.

Before the first use, press down firmly on the bottle lid until it clicks and shake for 30 seconds to activate. Recycle the lid and replace with the dropper. After cleansing in the morning and evening, blend 6 drops across face, neck and décolletage, avoiding the eye area. Leave to absorb before applying additional products.

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 become a deep brown colour.

Oxy-R Peptides is provided in 2x10mL bottles. Each bottle will stay potent for 6 weeks after opening. Activate the second bottle after finishing the first bottle.
