Key Ingredients:
1% Oxyresveratrol (Oxy-R)
One of the most powerful skin-brightening agents available in skincare, oxyresveratrol is naturally derived from the mulberry family. It helps to block the action of tyrosinase, an enzyme that is responsible for forming pigment in the skin. As a result, it transforms the appearance of uneven, dull skin tones.

Tetrapeptide-30
This illuminating peptide helps to minimise tyrosinase production and blocks the overproduction of melanin that causes visible dark spots.

Acetyl Glycyl Beta-Alanine
A brightening peptide solution that works by helping to block the transport of melanin to the skin cell. Therefore, helping to prevent visible pigment on the skin.

Hyaluronic Acid
An incredibly hydrating ingredient, hyaluronic acid attracts and retains more than 1,000 times its own weight in water and draws moisture in the upper layers of the skin; leaving it looking visibly supple and deeply hydrated.

STEP 1

Rated 5 out of 5 by from Oxy-R peptides [This review was collected as part of a promotion.] I purchased this to help even my skin tone and reduce pigmentation . I am a week into my second bottle and after using it twice daily have not seen any improvement . My skin does feel hydrated and no irritation . I will be returning to my vitamin c serum from the medika8 range .

Rated 4 out of 5 by from Yet to see results, too soon! [This review was collected as part of a promotion.] I am consistently using this serum. Love the way it sits on my skin. A little goes a long way too. Too soon to tell results yet.

Rated 5 out of 5 by from Useful I have age spots on cheeks and after 4 weeks of Oxy-R peptides colour looks softer/lighter, edges look more diffused, overall contrast is reduced. It blends more naturally into the cheeks. I'm going to use longer and looking forward for result. Also I have small size of post- pigmentation after PDL laser test so used as well on cheek. It's too early for result but pigment is much more lighter with Oxy-R peptides.

Rated 5 out of 5 by from Excellent post-detox skin clearing support Evens the skin tone from post-acne pigmentation very effectively. I only use on the areas needed and smooth the excess all over. I use it only in the evenings, on occasion, when I really need help post-detox and my skin has done it's clearing. I use it alone, maximum twice a week during such periods. It complements Crystal Retinal, Sleep Glycolic and Clarity peptides well - and as I don't use it in combination on any one evening, I know it is effective on its own.
