Sugar can also help you achieve clearer skin. The gentle abrasion of a sugar scrub removes damaged or dead skin cells and unclogs pores. This helps prevent many skin issues such as blackheads, skin blemishes, breakouts, and acne. Sugar can be one of the most effective ingredients when trying to lighten your skin; the granules help exfoliate and cleanse skin while opening pores for moisture. Mixed properly, sugar can lighten and soften your skin after just a few applications.
