How to Use

First-time use: If you're new to Oxy-R Peptides, we recommend a patch test at least 24 hours before first use.

  1. To activate for first use, press down firmly on the bottle lid until it clicks and shake for 30 seconds. Recycle the lid and replace with the dropper.
  2. After cleansing in the morning and evening, blend 6 drops of Oxy-R Peptides across the face, neck and décolletage - avoiding the eye area. Leave to absorb before applying your moisturiser.

Before application: 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. Store both bottles at room temperature and away from windows after activation.

Key Ingredients

  • 1% Oxyresveratrol (Oxy-R) – Naturally derived from the mulberry family, oxyresveratrol (pronounced 'ox-ee-ress-vera-trol') is one of the most powerful skin-brightening agents available in skincare. It helps to block the action of tyrosinase (the key enzyme responsible for forming pigment in the skin) to transform the look of dull, uneven skin tones.
  • Tetrapeptide-30 – An illuminating peptide that helps to minimise the production of tyrosinase, to block the overproduction of melanin that leads to visible dark spots.
  • 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 the ability to attract and retain more than 1,000 times its own weight in water, hyaluronic acid draws moisture into the upper layers of the skin; leaving the complexion hydrated and visibly supple.

Before you buy

Using this with microneedling

Microneedling opens channels for a few hours. What you apply afterwards, and when, changes the result.
