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.

Good to Know:
CLINICALLY PROVEN FORMULA
DERMATOLOGICALLY TESTED

Directions

STEP 1

STEP 2

NOTE
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.

Rated 5 out of 5 by from Great Serum [This review was collected as part of a promotion.] Lovely serum, been using along with other serums to challenge my skin. I love this and found it is helping. It is not a miracle serum but it has made my skin look softer and more alive.

Rated 5 out of 5 by from Absorbs into my skin well. [This review was collected as part of a promotion.] Arrived well packaged and with very clear instructions on how to activate. I have been using for about 4 weeks and it fitted into my Medik 8 routine. It is easy to activate and to apply. It absorbs well into my skin and although having sensitive skin, I have had no reaction to it at all. I bought this to help with pigmentation on my face and I haven’t noticed much difference from this. Maybe I haven’t been using it for long enough. Saying that it is a lovely product and happy to continue with it.

Rated 5 out of 5 by from Amazing [This review was collected as part of a promotion.] My newest holy grail product. 4 weeks in and I'm watching my hyperpigmentation and dark spots fade gently away. Combined with Crystal Retinal my 70 year old skin is brighter, clearer and firmer than ever. I can't be without it now.
