Really happy with this product, noticeably brightens my skin

Fantastic. I love this serum. It's easy to use and leaves my skin so dewy and moist.

I’ve just finished the 2 weeks using this serum and my skin is definitely brighter , clearer and the pigmentation spots on my cheekbones softened. I was initially worried about the drying side effect I read in the other customer reviews, so I made sure I layered 2 moisturisers on top morning and night (Neo Bright Cream and Hydra Cream) ...problem solved .

I love this product I have used it before and will use it again. It’s the perfect pick me up for my skin

As I have some pigmentation concern after my pregnancy, my salon recommended me to try the NeoBright Radiance C Ampoule which is a concentrated Vitamin C treatment. This set contains a powder and a serum initially stored in separate vials. Once the powder and the serum is mixed, it has to be used within 14 days. This is because the powder contains L-Ascorbic Acid (the most potent form of Vitamin C) and other extracts high in antioxidants, all of which will start deteriorating once it is in aqueous solution. Since both heat and light will speed up the oxidation process, I wrapped the bottle in foil and stored it in the fridge once it is mixed. The instructions on the website say to use one dropper each time, twice a day. One dropper is way too much for me, even when I brought the serum all the way down to my chest. I reduced this amount and started with 5 drops instead. There was a significant amount of sediment in the vial, so I had to shake it each time before use. The scent smelt a little "rusty" to me, but it was certainly not offensive. Initially I used 5 drops at a time for my face, neck and décollete. There was a slight tingling sensation after the first few applications but it went away. However, I could significantly noticed that my skin became quite dehydrated, and possibly also quite dry within a few days' time. I was not surprised given the high ethanol content (second ingredient in the serum). In order to keep going I reduced my usage to only 3 drops each time. My skin felt less tight, but at the same time I was not using anywhere close to the recommended dosage. After 14 days, my skin felt both tight and oily, which was a sign that my skin's hydration level had been thrown off-balance. I have also experienced small pimples and blocked pores in unusual places (again, this was a sign that my skin was over-producing oil to compensate for the dryness). That said, I think that there was a small reduction in my pigmentation. I gave the salon my feedback. The salon told me that some dryness is normal as it is an active product. However, the level of dehydration and dryness that I was experiencing (together with the breakout) certainly outweighed any benefit of the small level of pigment reduction. It is a shame that the ampoule contains so much ethanol in it, because I'd say the ingredients are otherwise A-List. The product is not suitable for my skin, but may suit oilier skin which is less prone to dryness and dehydration.
