Treatment for Acne
The goals of treatment are to help heal existing lesions, stop new lesions from forming, and prevent scarring. Medications can help stop some of the causes of acne from developing, such as abnormal clumping of cells in the follicles, high sebum levels, bacteria, and inflammation. Your doctor may recommend over-the-counter or prescription medications to take by mouth or apply to the skin.
Topical medications, which you apply to the skin, include:
- Over-the-counter products, such as benzoyl peroxide, which kills bacteria and may decrease the production of sebum.
- Antibiotics, which are usually used with other topical medications.
- Retinoids, which come from vitamin A and can help treat lesions and reduce inflammation. They can also help prevent the formation of acne and help with scarring.
- Salicylic acid, which helps break down blackheads and whiteheads and also helps reduce the shedding of cells lining the hair follicles.
- Sulfur, which helps break down blackheads and whiteheads.
Topical medicines come in many forms, including gels, lotions, creams, soaps, and pads. In some people, topical medicines may cause side effects such as skin irritation, burning, or redness. Talk to your doctor about any side effects that you experience.
For some people, the doctor may prescribe oral medications, such as:
- Antibiotics, which help slow or stop the growth of bacteria and reduce inflammation. Doctors usually prescribe antibioticsfor moderate to severe acne, such as severe nodular acne (also called cystic acne).
- Isotretinoin, an oral retinoid, which works through the blood stream to help treat acne and open up the pore. This allows other medications, such as antibiotics, to enter the follicles and treat the acne. Similar to topical retinoids, taking the medication by mouth can also help prevent the formation of acne and help with scarring.
- Hormone therapy, used primarily in women, which helps stop the effects of androgens on the sebaceous gland.
- Corticosteroids, which help lower inflammation in severe acne, including severe nodular acne.
Some people who have severe acne or acne scarring that does not respond to topical or oral medications may need additional treatments, such as:
- Laser and other light therapies. However, researchers are still studying the best types of light and the amount needed to treat acne.
- Injecting corticosteroids directly into affected areas of your skin.
- Superficial chemical peels that a doctor recommends and applies to the area.
- Filling acne scars with a substance to improve their appearance.
- Treating acne scars with tiny needles to help induce healing.
- Surgical procedures to help treat and repair scarring.
In addition to experiencing significant scarring, people of color can develop skin discoloration after acne heals. Your doctor can suggest a treatment approach that can fade existing dark spots. Using sunscreen when outdoors is especially important to help treat and prevent dark spots.
