Oxy-r Peptides™ Medik8

The power of peptides at an unprecedented concentration

Oxy-r Peptides™ is a professional peptide serum by Medik8, specifically formulated for skin prone to hyperpigmentation and dark spots. It contains 1% oxyresveratrol—a concentration exclusive to Medik8, previously unattainable in this formula.

It visibly brightens the appearance of dark spots and hyperpigmentation in as little as 7 days*, delivering clinically proven results across all skin tones.

Medik8 is a British cosmeceutical brand that centers its entire philosophy around one core principle: CSA. Vitamin C plus sunscreen by day, vitamin A by night. All other skincare steps are designed to complement this framework, rather than being a collection of random products.

Ingredients and Technology

At the heart of the formula is 1% oxyresveratrol—a concentration found exclusively in Medik8 products. It is responsible for visibly brightening hyperpigmentation and evening out skin tone.

Unlike other formulas, Oxy-r Peptides™ utilizes a Medik8-patented click-activated stabilization system, ensuring full peptide potency until the very last drop of the serum.

Clinically Proven

The brightening effect within 7 days was proven in an independent consumer study conducted over 4 weeks on 50 participants with skin hyperpigmentation.

Place in the CSA routine

In practice, this means a simple routine: in the morning, an antioxidant protects the skin from damage, a sunscreen blocks the radiation that causes this damage, and at night, vitamin A drives repair. Products from other categories—cleansing, hydration, eye care—are chosen to ensure they do not interfere with this rhythm.

How to use

• 1Before first use, press firmly on the bottle cap to release the oxyresveratrol into the serum, then shake vigorously for 30 seconds to thoroughly mix the ingredients.
• 2Replace the cap with the included pipette.
• 3After cleansing in the morning and evening, apply 6 drops of the serum to the face, neck, and décolletage, avoiding the eye area.
• 4Allow to absorb before applying your moisturizer.
• 5For optimal results, use regularly and finish each bottle within 6 weeks of activation.

Vitamin A products should be used only in the evening and introduced gradually—starting with two or three applications per week. Sunscreen is mandatory in the morning, regardless of the season.
