as a preface, ive been using this serum for about 4-ish months now. this is the only thing in my routine that has active ingredients (other than an acne spot-treatment which I only use at different times with reasonable wait/rest times) i also had a huge breakout about 3 months ago from a bad product which left me with a dozen cystic pimples and had a huge part of my face irritated the whole time. This product got rid of the cystic acne and it makes my face pretty smooth since I never actually exfoliated prior to using this product. (Because for some reason this product doesn't actually have vitamin c in it, no ascorbic acid or anything, rather it has salicylic acid which just makes it a salicylic acid serum basically lol) now im left with acne scars which ive noticed it doesnt do much to them. even though is has salicylic acid and panthenol in it, ive started to use the ordinary niacinamide serum with this and it seems to help the scars quite a bit. Its a great product and would recommend for oily, sensitive, acne-prone skin.

I had purchased three bottles of this serum. For months, i thought my skin will be as good as it used to be. I used this serum with the other light complete series even the compact powder. But, It never gets any better.
I know for sure that this serum is very hydrating.
