this really helps lighten my pimple marks and heals my pimple really fast whenever I'm having a breakout. I will definitely repurchase this and will be sending one to my cousin too.

Works for fresh scars

Been using this almost nightly for close to a month, in conjunction with the OST Vitamin Sleep 9 to 5 cream, and I have noticed a gradual fading of fresh pimple scars.  Cannot yet see other claims of blackhead removal, whitening etc... Although Vit C as an antioxidant should fight the effects of aging over long periods of use.  I find the serum quite sticky and stinging on the face, so I'm not sure if I will keep using it as I do not have much pimple/acne problems to begin with.

Love hate relationship
Maybe this serum dont suit on me. Everytime i used at night routine, i got white and small bump on cheek. It also made my skin looks darker. I only use 1-2 week aprox.
