Hi I recently have been breaking out very badly and suffer from dark spots what can I do to lighten then and also get rid on acne?

Manage, not cure. Topical benzoyl peroxide and/or tretinoin are often enough to control your acne until it remits on its own. There's no telling when this will happen. Remember that acne's really not related in any obvious way to lifestyle, diet, or anything else we understand. I'd suggest you leave the pigmented areas alone; bleaches can disfigure you.
