Chemical peel, laser resurfacing and dermabrasion can give you instant glow, but it actually poses more damage to your skin in the long-run, well I think.
Good skin is largely hereditary, so if your parents don't have good skin, just forget it. However there are ways to improve skin condidtions from OK to fair:
-get away from sun exposure
-a balanced diet with regular multi-vitamin intake
-rest well
-use a good moisturizer
