Add the Medik8 Oxy-R Peptides into a morning or evening skincare routine to help target the look of hyperpigmentation and age spots for a brighter, more even tone.

This potent skincare treatment is powered by patented brightening technology. Stabilised oxyresveratrol (oxy-r) works to minimise the appearance of hyperpigmentation in the skin, while a click-activated system maximises the stability of the oxy-r for optimum results.

Halfway through but would already recommend

I am a longtime acne sufferer so a product designed to improve the appearance of marks speaks to me. I only finished one bottle - the package comes with 2 bottles, each to be used in max 6 weeks; there is only one dropper, so don't throw it away with the first bottle :) I noticed an overall brightening of my skin, so I would definitely recommend this.

I have used EVERYTHING to try and get rid of my post-inflammatory hyperpigmentation and this was it. I use it day and night as my first step. It made a HUGE difference. Not only did it get rid of marks I already had but it also prevented new ones from appearing during the summertime and during the purge part of the Retinal I was using. I recommend it if you are starting Retinal and know it's going to upset your skin but don't want to give up. Amazing, one month in the difference was incredible. ABSOLUTELY recommend it.

About to finish first set and I will keep going…

I’m a few applications away from finishing the second bottle of my first purchase. I’ve used it religiously morning and night. I bought as an attempt to reduce some pigmentation/possibly melisma across my checks (like a mask under eyes) and on my forehead. Now I know that nothing was going to entirely remove it but I do think this product has definitely prevented it growing in size during summer and has faded the marks. The tone of my overall skin is improved and I am pretty sure I will repurchase to give it long enough to work more.

Has made a noticeable dent in my post inflammatory hyperpigmentation (every time I get a breakout, it leaves a coloured mark). I saw a difference overnight - no joke. I also took before and after photos. After 2 weeks I could see the purple-redish marks almost disappear as I swiped between the two photos. I am now on my second bottle (one box comes with 2 small bottles. Once you open a bottle it must be used within 6 weeks. The package comes with instructions - be sure to read them!). Bottom line? The Oxy-R peptides work, and, for me, cause NO irritation in the process (no breakouts, no rash, no itching, etc.). I am so grateful for this product.

I have had a couple of stubborn pigmentation spots for quite a few years now. My targeted skincare product I was using for it was Skinceuticals Discolouration Defence Serum. It did help to improve them but after a couple of years use it hit a plateau. I decided to give this ago and I am so glad I did! It is very reasonably priced and the results are impressive - it picked up where Skinceuticals had finished. I’m on my third box of these now and still noticing improvements. My pigmentation hasn’t fully disappeared but there is a definite, noticeable improvement - my facialist noticed and wanted to know what I had been using! In addition to improving my pigmentation it has also firmed my skin. The results are surprising considering it feels like putting water on your skin. In the box you have two bottles, you use one bottle first which stays potent for six weeks. You then activate the second bottle. It absorbs pretty much immediately and has never caused any sensitivity issues for me. It fits in effortlessly with the rest of my skincare products and is a permanent serum for me now.
