Effective over-the-counter medicine for acne bumps?

AHA, BHA, BPO. Glycolic acid (aha, Alpha hydroxy acid), salicylic acid (bha, beta salicylic acid), lactic acid, urea, tea tree oil, benzoyl peroxide can all help with acne bumps.
Let me if I could he. Tiny under the skin bumps, some where we had pimples before, and some at the base of some facial hairs. They could be dormant pimples? Trapped puss. Use the salicylic product, and benzoyl peroxide product, to help with condition, i would advice to use it under the supervision of the dermatologist.
