Keratolytic products such as salicylic acid, glycolic acid, and benzoyl peroxide all dissolve blackheads, writes Dr. Bailey Skin Care. These products work by loosening the dead skin cells in pores and on the skin's surface.
Comedones, or blackheads, are tiny plugs made of skin germs, dead skin cells and other debris that clog pores, states Dr. Bailey Skin Care. These plugs are naturally occurring and normal, but if they stick together and form a clump they can get stuck in pores, causing blackheads.
Some skin care products can increase blackhead production, particularly products that contain oils such as petrolatum and mineral oil, according to Dr. Bailey Skin Care.
