Pimples and blackheads are two types of acne lesions, which treatments such as benzoyl peroxide, topical or oral antibiotics, and retinoids may help to reduce, according to WebMD. Another common treatment is hormone therapy for women, particularly in the form of prescription birth control pills.
Pimples and blackheads form when dead skin cells and oil clog the pores of the skin, explains the University of California. Sulfur may help treat acne because it both removes skin cells and kills bacteria that cause acne. Nonprescription facial products containing salicylic acid, lactic acid and other active ingredients also reduce acne lesions by ridding the skin of dead cells and excess oil, suggests the Mayo Clinic. Professional procedures, such as microdermabrasion, may help treat blackheads as well, notes Huffington Post.
