Acne appears to be strongly inherited with 81% of the variation in the population explained by genetics.[15] Studies performed in affected twins and first-degree relatives further demonstrate the strongly inherited nature of acne.[2][15] Acne susceptibility is likely due to the influence of multiple genes, as the disease does not follow a classic (Mendelian) inheritance pattern. Several gene candidates have been proposed including certain variations in tumor necrosis factor-alpha (TNF-alpha), IL-1 alpha, and CYP1A1 genes, among others.[19] The 308 G/A single nucleotide polymorphism variation in the gene for TNF is associated with an increased risk for acne.[40] Acne can be a feature of rare genetic disorders such as Apert's syndrome.[15] Severe acne may be associated with XYY syndrome.[41]
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.

The Daily Skin Clearing Treatment is an all-over 2.5 percent benzoyl peroxide cream that also touts calming bisabolol and allantoin to alleviate the dryness and irritation that can crop up mid-treatment. Anyone frustrated with oil-slick skin will also love this part of the regimen — it creates a satin mattifying effect, instantly transforming shininess into a glow.

Blemishes on your new baby's face aren't necessarily acne, however. Tiny white bumps that are there at birth and disappear within a few weeks are called milia, and they're not related to acne. If the irritation looks more rashy or scaly than pimply, or it appears elsewhere on your baby's body, he may have another condition, such as cradle cap or eczema.

Tea tree oil is renowned for being good for your skin. In addition to this, it also contains anti-bacterial and anti-fungal properties, which makes it highly beneficial for acne treatment. In fact, studies that compare tea tree oil to the acne medication benzoyl peroxide shows it to be just as effective. But please remember to dilute tea tree oil before you use it; otherwise, your skin may get irritated.
Misperceptions about acne's causative and aggravating factors are common, and those affected by it are often blamed for their condition.[176] Such blame can worsen the affected person's sense of self-esteem.[176] Until the 20th century, even among dermatologists, the list of causes was believed to include excessive sexual thoughts and masturbation.[165] Dermatology's association with sexually transmitted infections, especially syphilis, contributed to the stigma.[165]
Cystic-acne sufferers know that a cyst is not the same beast as a standard pimple. While whitehead pimples sit on the surface of the skin (which, though unsightly, means they’re easier to treat and conceal), cysts can linger under the surface of the skin like oil-filled balloons, growing bigger and more inflamed over time. The scarring can be severe, too, making skin appear pockmarked and fissured, which is why dermatologists approach it with a powerful combination of topical treatments and antibiotics, moving on to scorched-earth methods like Accutane or a hormonal drug like Spironolactone if those fail.
Post-inflammatory hyperpigmentation is not an acne scar, but a red, pink, brown or tan skin discoloration where acne has previously flared up. It'll usually disappear on its own in a year or so. Many skin lightening products claim to help reduce the visibility of these acne "scars." Their active ingredient, hydroquinone, works to slow melanin production and can reduce dark brown marks, but melanin isn't the cause of red and pink acne discolorations. A better option is to use the best foundation for acne prone skin you can find to hide the marks until they naturally fade away.
How to Handle It: Pair two of the best-known acne-fighting ingredients, salicylic acid and benzoyl peroxide, in the week leading up to your period. (If you're feeling bloated, now's the time to do it.) The combo can help prevent hormonal acne from happening in the first place. Zeichner suggests following a salicylic acid wash, like fan-favorite Neutrogena Oil-Free Acne Wash Pink Grapefruit Facial Cleanser ($7), with a benzoyl peroxide spot treatment, such as Murad Acne Spot Fast Fix ($22). If you're still seeing zits, "visit your dermatologist to discuss prescription options, like birth control pills, oral spironolactone — which blocks oil — or topical Aczone 7.5 percent gel," says Zeichner. "It's shown to be particularly effective in adult women without causing irritation." Oral contraceptives level out those hormone fluctuations, keeping your oil production normal and your skin clear.

And a retinoid, which we’ve touched on before, is beneficial for exfoliating the skin and purging your pores of dirt and oil, which is why Zeichner says they’re helpful for cysts, too. He recommends Differin, the only prescription-strength retinoid that’s available over the counter, and which many derms here have suggested to us before for acne-prone skin. He says you can use a pea-size amount and start applying it every other night as your skin gets adjusted to it (or combine it with benzoyl peroxide and salicylic acid for a stronger mixture).

Many skin conditions can mimic acne vulgaris, and these are collectively known as acneiform eruptions.[28] Such conditions include angiofibromas, epidermal cysts, flat warts, folliculitis, keratosis pilaris, milia, perioral dermatitis, and rosacea, among others.[20][72] Age is one factor which may help distinguish between these disorders. Skin disorders such as perioral dermatitis and keratosis pilaris can appear similar to acne but tend to occur more frequently in childhood, whereas rosacea tends to occur more frequently in older adults.[20] Facial redness triggered by heat or the consumption of alcohol or spicy food is suggestive of rosacea.[73] The presence of comedones helps health professionals differentiate acne from skin disorders that are similar in appearance.[8] Chloracne, due to exposure to certain chemicals, may look very similar to acne vulgaris.[74]
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.[127] Hormone therapy is effective for acne even in women with normal androgen levels.[127]
If your acne is severe, painful, or refusing to get lost, you may just be beyond what an over-the-counter treatment can do. Not only can a professional set you up with the really powerful stuff, but also Fitz Patrick explains that “working closely with an aesthetician or dermatologist means you can keep tweaking a routine to make it work best for you.”
The Anti-Redness Exfoliating Solution is mostly water, but its 2 percent salicylic acid is enough to eat through oil and remove the dead skin cells clogging your pores — and it boasts a higher concentration than nearly every other kit we looked at. Sodium hyaluronate, the super-moisturizing humectant we fell in love with in our review on the Best Face Moisturizer, also caught our eye sitting smack dab in the middle of the ingredients list.

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.”
