The Vitamin C + PHA Serum from Neostrata pairs vitamin C with gentle exfoliation to restore a more even skin tone. The exfoliator, polyhydroxy acid (PHA), helps the vitamin C to let it work more effectively, for a brighter and more radiant appearance, in as little as one week.
 
This serum is precisely formulated at an optimised pH and concentration level for effective results and is clinically proven to visibly target dark spots, uneven skin tone and texture.
