Because of the tumeric root extract, it's yellow in colour and light weight. It is alcohol, fragrance, and essential oil-free.
It absorbs fast into the skin, and after cleansing, I normally use 3 to 4 drops to cover my face before slapping on other hydrating products.
This serum is love. It fades PIH very quickly, almost in a week's time. It's also efficient, in my opinion, because it contains other exfoliating acids like Mandelic and Salicylic, which increase its potency. I've been using it for about a month and a half and I think it's helped my melasma a bit. It's not a huge change, but I haven't used it long enough .I also prefer to use it twice a day on occasion to really tackle my pigmentation and get rid of it asap.
If you have PIH, I highly recommend it
