VIDI Skin Care launches vitamin C serum with Alpha and Beta Hydroxy Acids which work as dark area corrector and fades age and dark spots in time.
The alpha and beta hydroxy acids are really moderate skin exfoliators so they take off the upper dead skin then the vitamin c serum goes much deeper and works much better than other serums
