It abit sticky but works on me. But it also makes me feel itchy at the same time.

Honestly i feel a really big difference whenever i'm running out of this serum. This makes my skin so much better. Even for my "wrinkles" (i'm on my 20's so this is small wrinkles tho) after some use it really dissapear. But when i'm running out of this product then it appears again. It makes your face brighter... Anyway yeah, i recommand it.  

Love that it arrives sealed separately from the dropper. Has helped with hyper pigmentation. 

Good serum. My skin is a little bit brighter. Maybe using in long time will have better effect. 

This product has been talked about a lot in the beauty community and I see why. It is an excellent vitamin C serum. My advice is to use this right away. I bought a back up of this and left it stored for a while, when I opened it sadly it has gone bad so you have to be careful and follow the storage instructions.

I've been using this for more than a month now, and I did notice a bit of lightening. Maybe if I will continue it, (or if I try the C.21 one?) I'd see more visible results. I was afraid it'd be harsh on my skin, but other than some heat, I didn't feel any stinging at all.

i love this serum, but not good smell i dont like the smell

It is a  good product. Does its job :)

very good, recommended!

A  lightweight and fast absorbing serum. 

this is by far the best serum I've tried. it helps brighten up, alms my acne and make
my skin look so much healthier.  

first i love how it's smell like fresh orange ! i like it but after i use it it's feel sticky on my face i don't know why 

This serum is the best for me. It helps me to reduce scars.   

I really brighten my skin well! But i have a sensitive skin so it is a bit irritating to me when i put it on.

Doesn't seem to be working.. if it is, it should be a very slow, gradual help because my acne scars are lightening up no faster than it normally does..

Its a nice serum, leaves a little bit of a sticky residue. 

To be honest I haven't seen a big difference in the brightening effect, but I need to use it a bit more diligently to see results. 

I'm in love with this serum. I suffered because of acne scar for years and it was like my savior now.
