Acne is often considered a teenagers' problem but it can happen to adults, too. Most cases can be treated effectively with products purchased in a store, the American Academy of Dermatology (AAD) states. There are several different over-the-counter product types. Each has certain active ingredients that work in different ways. A person who does not have any luck with one store-bought product may find that another resolves his acne problem.
Benzoyl Peroxide
Many acne products sold in stores contain benzoyl peroxide, an acne-fighting agent the Mayo Clinic calls the most effective over-the-counter ingredient. It kills bacteria, gets rid of deal skin cells so they cannot clog pores and cuts down on excess oil. It is sold in concentrations ranging from 2.5 percent to 10 percent. It can dry out skin and cause swelling, redness and scaling, especially when used at the highest strength. It also makes skin more sensitive to ultraviolet rays. The AAD warns it can also bleach hair, clothes and towels.
Salicylic Acid
Many stores sell acne treatment products containing salicylic acid in concentrations ranging from 0.5 percent to 2 percent, and in many forms including pads, creams and lotions. These products slow down skin cell shedding inside follicles, the Mayo Clinic says. This prevents pore clogging. Salicylic acid can also break down blackheads and whiteheads. It might sting and irritate the skin, especially at stronger concentrations.
Resorcinol and Sulfur
Resorcinol and sulfur are used together in some store-bought acne products. They cut down on excessive oil and get rid of dead skin cells. They can also break down blackheads and whiteheads. They can cause redness and peeling, which the Mayo Clinic states can happen several days after product application.
Astringents
Acetone, alcohol and other astringents are often sold in stores as acne treatments. They are used to wash the affected skin thoroughly, removing dirt and oil. This deep cleaning helps to prevent pimples by killing bacteria and keeping the oil level down, the AAD explains. The Mayo Clinic states that some astringent users feel stinging or a mild burning sensation on the skin.
