It seems everyone agrees on the St Ives and yes its a good exfoliator. But be careful to use only once or twice a week on your face.....
Another chemical exfoliator is Glycolic peel and its really effective to remove the acne marks. Do NOT use it on active acne......Benzoyl peroxide 5% is very good for removing acne.......
Teenagers and young people should always talk to good skin specialist before using any product on Acne coz it might backfire.....
People in India may go to Kaya skin clinic. They are good but they have tendency to squeeze money out of you......If you are in a a big city like Mumbai and Banglore, try going to good hospitals. They also give all skin treatments, peels etc at reasonable rates.,.....
