Benzoyl peroxide attacks the P. acnes bacteria. However, one of its main side effects is dryness: If you’re going to use anything with benzoyl peroxide, make sure to moisturize afterwards. Sulfur and azelaic acid are less common and less severe alternatives to benzoyl peroxide. Dr. Peter Lio, assistant professor of clinical dermatology at Northwestern University, says sulfur-based treatments are “a good fit for patients who can’t tolerate the side effects of benzoyl peroxide.”
If you have acne that's not responding to self-care and over-the-counter treatments, make an appointment with your doctor. Early, effective treatment of acne reduces the risk of scarring and of lasting damage to your self-esteem. After an initial examination, your doctor may refer you to a specialist in the diagnosis and treatment of skin conditions (dermatologist).
Acne inversa (L. invertō, "upside down") and acne rosacea (rosa, "rose-colored" + -āceus, "forming") are not true forms of acne and respectively refer to the skin conditions hidradenitis suppurativa (HS) and rosacea.[25][26][27] Although HS shares certain common features with acne vulgaris, such as a tendency to clog skin follicles with skin cell debris, the condition otherwise lacks the defining features of acne and is therefore considered a distinct skin disorder.[25]

Oral isotretinoin is very effective. But because of its potential side effects, doctors need to closely monitor anyone they treat with this drug. Potential side effects include ulcerative colitis, an increased risk of depression and suicide, and severe birth defects. In fact, isotretinoin carries such serious risk of side effects that all people receiving isotretinoin must participate in a Food and Drug Administration-approved risk management program.
Aside from adding bacteria to your skin, these forms of contact can irritate the skin, adding to the appearance of redness and causing increased inflammation. In the event that your pimples get ruptured during this process, the oil and bacteria that was trapped inside could spread to the surrounding skin on your face, which causes acne to spread. So, not only will rubbing, squeezing and scratching leave your acne-ridden skin further irritated, it will increase the amount of acne you will have to deal with.
If you’re looking for a hormonal solution to your acne but don’t want to take a combined oral contraceptive, spironolactone may be the answer. This oral medication is a potassium-sparing diuretic originally designed to treat high blood pressure, but is now also used to treat acne. It mainly functions by reducing sebum production, leading to less acne formation13. If you are able to get pregnant, you don’t necessarily need to take a combined oral contraceptive, but you will want to use some form of birth control since spironolactone, like Accutane, is a well-known teratogen and is known for causing birth defects.

Acne appears when a pore in our skin clogs. This clog begins with dead skin cells. Normally, dead skin cells rise to surface of the pore, and the body sheds the cells. When the body starts to make lots of sebum (see-bum), oil that keeps our skin from drying out, the dead skin cells can stick together inside the pore. Instead of rising to the surface, the cells become trapped inside the pore.
