How Oxy-r Peptides works
  1. Oxy-R Peptides harnesses the powers of the benchmark brightening agent, oxyresveratrol, in an unprecedented 1% concentration. A gentle yet potent antioxidant, Oxy-R is used in skin care to treat areas of hyperpigmentation, dark spots, and post-inflammatory pigmentation. It has been proven to be 33 times more effective than kojic acid[1], and works by helping to block the functioning of the enzyme tyrosinase, the key enzyme responsible for the formation of pigments in the skin.
  2. Although exceptionally potent, Oxy-R is an incredibly unstable ingredient. With another unique stability innovation, Medik8 has carefully crafted a patented system to obtain the unique benefits of high potency stabilized oxyresveratrol. Keeping the 1% Oxy-R stored in a preservative serum in the cap to protect its potency, Oxy-R Peptides uses Click-Activated packaging technology to ensure the formula remains stable from activation to the last drop.
  3. "Oxy-R Peptides" offers a triple threat against hyperpigmentation, with two brightening peptides that work together with Oxy-R to improve visible skin tone. Tetrapeptide 30 helps block the overproduction of pigment that can lead to visible discolorations and uneven skin tone, while acetylglycine beta-alanine helps stop localized patches of pigment from appearing on the skin.

How to use

  1. Surface cleaning
  2. Recycle the cap and replace it with the dropper.
  3. After cleansing in the morning and evening, apply 6 drops of Oxy-R Peptides to the face, neck and décolleté, avoiding the eye area.

  4. Let it absorb before applying moisturizer.

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