We suggest avoiding spot treatments. “Benzoyl peroxide, when placed on red spots, can actually cause more irritation and inflammation to the area. It’s best used to prevent red bumps and pustules, and applied all over the area you want to treat,” said Townsend, who was also quick to naysay a spot-treat-only approach: “Acne affects all of the pores. If someone is going to spot treat against my advice, I still suggest they spot treat one day and treat the whole face the next.”
Frequently used topical retinoids include adapalene, isotretinoin, retinol, tazarotene, and tretinoin.[47] They often cause an initial flare-up of acne and facial flushing, and can cause significant skin irritation. Generally speaking, retinoids increase the skin's sensitivity to sunlight and are therefore recommended for use at night.[1] Tretinoin is the least expensive of the topical retinoids and is the most irritating to the skin, whereas adapalene is the least irritating to the skin but costs significantly more.[1][84] Most formulations of tretinoin cannot be applied at the same time as benzoyl peroxide.[15] Tazarotene is the most effective and expensive topical retinoid, but is not as well-tolerated.[1][84] Retinol is a form of vitamin A that has similar but milder effects, and is used in many over-the-counter moisturizers and other topical products.
Accutane is especially good for cystic acne in women and body acne in men. “Oral vitamin A basically shuts down your sebaceous glands. If you suppress [them] for a long enough period, you can cure someone of their acne, and about 50 percent do hit that cure rate,” says Linkner. A course of Accutane can take about six to nine months. Sometimes patients need to repeat the course at a higher dosage in order to truly eliminate acne.
Kathyrn Bowling’s son Gus was only two weeks old when she first noticed red bumps spreading on his face: newborn acne. At the time, the Atlanta mom wasn’t concerned about something so common (and harmless) as baby acne. I was worried about so many other things, like how much he was eating and whether I would get enough sleep,” she says. “In the grand scheme of things, a few bumps on his face didn’t seem too bad.”

The costs and social impact of acne are substantial. In the United States, acne vulgaris is responsible for more than 5 million doctor visits and costs over US$2.5 billion each year in direct costs.[13] Similarly, acne vulgaris is responsible for 3.5 million doctor visits each year in the United Kingdom.[20] Sales for the top ten leading acne treatment brands in the US in 2015, have been reported as amounting to $352 million.[176]
Dermal or subcutaneous fillers are substances injected into the skin to improve the appearance of acne scars. Fillers are used to increase natural collagen production in the skin and to increase skin volume and decrease the depth of acne scars.[146] Examples of fillers used for this purpose include hyaluronic acid; poly(methyl methacrylate) microspheres with collagen; human and bovine collagen derivatives, and fat harvested from the person's own body (autologous fat transfer).[146]

Most studies of acne drugs have involved people 12 years of age or older. Increasingly, younger children are getting acne as well. In one study of 365 girls ages 9 to 10, 78 percent of them had acne lesions. If your child has acne, consider consulting a pediatric dermatologist. Ask about drugs to avoid in children, appropriate doses, drug interactions, side effects, and how treatment may affect a child's growth and development.
Chemical peels can be used to reduce the appearance of acne scars.[32] Mild peels include those using glycolic acid, lactic acid, salicylic acid, Jessner's solution, or a lower concentrations (20%) of trichloroacetic acid. These peels only affect the epidermal layer of the skin and can be useful in the treatment of superficial acne scars as well as skin pigmentation changes from inflammatory acne.[32] Higher concentrations of trichloroacetic acid (30–40%) are considered to be medium-strength peels and affect skin as deep as the papillary dermis.[32] Formulations of trichloroacetic acid concentrated to 50% or more are considered to be deep chemical peels.[32] Medium-strength and deep-strength chemical peels are more effective for deeper atrophic scars, but are more likely to cause side effects such as skin pigmentation changes, infection, and small white superficial cysts known as milia.[32]

Hormonal treatments for acne such as combined birth control pills and antiandrogens may be considered a first-line therapy for acne under a number of circumstances, including when contraception is desired, when known or suspected hyperandrogenism is present, when acne occurs in adulthood, when acne flares premenstrually, and when symptoms of significant sebum production (seborrhea) are co-present.[128] Hormone therapy is effective for acne even in women with normal androgen levels.[128]
Coconut oil is all the rage, with uses ranging from hair conditioning to cooking. But some swear by it as a natural acne treatment. To use coconut oil as an acne treatment, you can include it as part of a healthy diet. The fatty acids like lauric acid and caprylic acid are metabolized into antibacterial agents in the body. Or, you can apply a very small amount and rub directly onto your skin after cleansing for an extra hydrating boost.
If you notice that you’re breaking out right around your period every month, your acne might be linked to hormones. “A sensitivity to the hormones called androgens manifests in the form of cystic acne,” says Linkner. Androgens, namely testosterone, cause the skin to produce more sebum. More sebum equals more acne. Birth control, which has estrogen and progestin, helps keep hormones balanced and skin clear. Ortho Tri-Cyclen, Estrostep, and YAZ are all FDA-approved as acne treatments.
Isotretinoin is a standard prescription that you can get from your doctor. You may have heard of the brand names Absorica®, Accutane®, Amnesteem®, Claravis®, Myorisan®, Sotret® and Zenatane™. CBS News reports that Accutane has some pretty serious side effects, possibly even death. One man reported severe inflammatory bowel disorder that required removal of his colon. It’s been noted that it can cause miscarriage, birth defects, increased internal skull pressure, bone mineral density problems, depression, psychosis, suicide, aggressive or violent behaviors, acute pancreatitis, cardiovascular issues, deafness, hepatitis, bowel disease, excessive bone growth, night blindness and sight loss.

Many different treatments exist for acne. These include alpha hydroxy acid, anti-androgen medications, antibiotics, antiseborrheic medications, azelaic acid, benzoyl peroxide, hormonal treatments, keratolytic soaps, nicotinamide, retinoids, and salicylic acid.[75] They are believed to work in at least four different ways, including the following: reducing inflammation, hormonal manipulation, killing P. acnes, and normalizing skin cell shedding and sebum production in the pore to prevent blockage.[76] Common treatments include topical therapies such as antibiotics, benzoyl peroxide, and retinoids, and systemic therapies including antibiotics, hormonal agents, and oral retinoids.[20][77]
The approach to acne treatment underwent significant changes during the twentieth century. Retinoids were introduced as a medical treatment for acne in 1943.[83] Benzoyl peroxide was first proposed as a treatment in 1958 and has been routinely used for this purpose since the 1960s.[168] Acne treatment was modified in the 1950s with the introduction of oral tetracycline antibiotics (such as minocycline). These reinforced the idea amongst dermatologists that bacterial growth on the skin plays an important role in causing acne.[164] Subsequently, in the 1970s tretinoin (original trade name Retin A) was found to be an effective treatment.[169] The development of oral isotretinoin (sold as Accutane and Roaccutane) followed in 1980.[170] After its introduction in the United States it was recognized as a medication highly likely to cause birth defects if taken during pregnancy. In the United States, more than 2,000 women became pregnant while taking isotretinoin between 1982 and 2003, with most pregnancies ending in abortion or miscarriage. About 160 babies were born with birth defects.[171][172]

How to Handle It: Speaking of touching, don't! Picking it, squeezing it, or poking at it will only worsen the situation. These may disappear on their own after a few days. Otherwise, Zeichner suggests visiting your dermatologist for a shot of cortisone, which will reduce inflammation and shrink it in just 24 to 48 hours. But if a last-minute appointment isn't in the cards, play mad scientist. First, ice the area, and then apply salicylic acid gel, benzoyl peroxide gel, and 1 percent hydrocortisone cream. The combo will calm skin, kill bacteria, and draw out excess oil from the pimple — all things necessary to take this down, says Zeichner.
