"This product is genius. I feel like I haven't talked about it enough and it deserves more attention. So this has 1% oxyresveratrol which is a very potent yet gentle antioxidant that has all of the beneficial antioxidant effects but it also has the ability to inhibit tyrosinase which is an enzyme in our skin that produces melanin that produces pigment. So when you block that enzyme from functioning you reduce that excess pigment formation. In addition to the oxyresveratrol this also has tetrapeptide 30 which is a peptide that also blocks tyrosinase. So, specifically for people who have hyperpigmentation and especially for those who are too sensitive to use vitamin C, which is also great for hyperpigmentation, I highly, highly recommend you try this. I also feel like I should say since this bottle looks incredibly small, that one package of this comes with two bottles and you activate them separately so that you go through one entire bottle and then you activate the second bottle because the big issue with antioxidants is they can be quite unstable. Medik8 has done a very smart thing here and they have you go through half the product at once and then you can activate the other half of the product so that what you're using is always going to be in its most efficacious form."

"This is a product I hear nobody speak about. It's just gone totally under the radar, but I think it's a true holy grail for certain people. What this does is it uses oxyresveratrol, which is a patented antioxidant known for being able to really brighten and lift the tonality of the skin, but it also is fantastic at fading hyperpigmentation, particularly stubborn hyperpigmentation. I gave it to my mom who has much more stubborn hyperpigmentation and melasma. She used both bottles and she absolutely loves it because it's helped lift the hyperpigmentation and the melasma in a way that a lot of things haven't. Melasma is particularly tricky to treat. You can reach for prescription things like hydroquinone but they come with a lot of side effects and you have to get the prescription. I would say this is like the next best thing when it comes to fading stubborn hyperpigmentation, lifting the skin, and just giving a really nice overall boost to radiance. It's also not super expensive."
