Oftentimes, our first instinct when we encounter bumps, pimples and other blemishes on our skin is to touch it. But if you’ve been dealing with acne for a while, you’ve probably learned by now that these practices only make acne and skin problems worse. For starters, our hands come into contact with more bacteria, pathogens and contaminants than any other part of our bodies. Even when we try to wash our hands often, there is only so much of that we can avoid putting on our faces every time we reach out to touch it. So, there’s the fact that we could be adding harmful bacteria our facial skin to begin with. But it doesn’t end there.
If a pore is open, it’s called a blackhead or “open comedo”. Because of the opening, contact with the air oxidizes the dead skin cells inside the pore. The air contact turns the melanin inside them darker in color, similar to the way a peeled banana left exposed to the air will darken. This is how the blackhead forms. The color of a blackhead is not because of dirt. It’s a mixture of air and the skin pigment called melanin.

The best acne treatment system will include a cleanser, exfoliant and a treatment product that can be used daily. The idea is to have a product that cleans and clears clogged pores, kills bacteria, exfoliates to remove dead cells and spot treats trouble spots to combat stubborn blemishes and reduces inflammation and redness. For those with oily skin, a toner may be useful. For those with black heads, deep cleansing pore strips will help. If you have dry skin, foaming face wash would be something you want to avoid. The point is, a carefully tailored system is the best approach to an effective acne treatment.
Acne vulgaris and its resultant scars have been associated with significant social and academic difficulties that can last into adulthood, including difficulties obtaining employment.[30][177] Until the 1930s, it was largely seen as a trivial problem among middle-class girls – a trivial problem, because, unlike smallpox and tuberculosis, no one died from it, and a feminine problem, because boys were much less likely to seek medical assistance for it.[165] During the Great Depression, dermatologists discovered that young men with acne had difficulty obtaining jobs, and during World War II, some soldiers in tropical climates developed such severe and widespread tropical acne on their bodies that they were declared medically unfit for duty.[165]
The predisposition to acne for specific individuals is likely explained by a genetic component, a theory which is supported by studies examining the rates of acne among twins and first-degree relatives.[2] Severe acne may be associated with XYY syndrome.[39] Acne susceptibility is likely due to the influence of multiple genes, as the disease does not follow a classic (Mendelian) inheritance pattern. Multiple gene candidates have been proposed including certain variations in tumor necrosis factor-alpha (TNF-alpha), IL-1 alpha, and CYP1A1 genes, among others.[18] Increased risk is associated with the 308 G/A single nucleotide polymorphism variation in the gene for TNF.[40]
Cortisone is a quick fix for acne emergencies. We mean got a big board meeting tomorrow kind of quick. Go into the dermatologist’s office for a shot of this corticosteroid, and acne will disappear in 24 to 48 hours. The treatment works to curb inflammation, which makes it best for cystic breakouts and can be really good at combatting hormonal flare-ups. If done incorrectly, a cortisone shot can leave a small depression in the skin that lasts about eight weeks. “It’s a rare side effect that happens if dosage of cortisone is too high,” explains Linkner. “You want to go to someone who knows what they’re doing.”

Considerations: Because tazarotene is a retinoid (vitamin A derivative), like Accutane, it should not be used by women who are pregnant because of potential harm to the fetus. Exposure to sunlight should be avoided. Wind or cold may be more irritating when taking tazarotene. Side effects occured in 10-30% of patients and included dry peeling skin, burning, stinging, dry skin, redness, and itchiness.

“Acne cleansers with these ingredients will gradually unclog pores, reduce the size of existing blackheads and slow or stop the formation of new ones,” she says. “Benzoyl peroxide is also the best ingredient for treating the acne-causing bacteria called p. acnes. In fact, study after study continues to show that benzoyl peroxide is more effective than prescription topical antibiotics at treating p. acnes.”
Postinflammatory hyperpigmentation (PIH) is usually the result of nodular acne lesions. These lesions often leave behind an inflamed darkened mark after the original acne lesion has resolved. This inflammation stimulates specialized pigment-producing skin cells (known as melanocytes) to produce more melanin pigment which leads to the skin's darkened appearance.[34] People with darker skin color are more frequently affected by this condition.[35] Pigmented scar is a common term used for PIH, but is misleading as it suggests the color change is permanent. Often, PIH can be prevented by avoiding any aggravation of the nodule, and can fade with time. However, untreated PIH can last for months, years, or even be permanent if deeper layers of skin are affected.[36] Even minimal skin exposure to the sun's ultraviolet rays can sustain hyperpigmentation.[34] Daily use of SPF 15 or higher sunscreen can minimize such a risk.[36]

The dermatologist Dr. Dennis Gross did a major study on water and its effect on skin and he found that the heavy metals in tap water can actually ruin the benefits expensive lotions and serums do for skin. Some cities (New York and L.A., for example) have worse water than others (Seattle, for example). While some dermatologists aren't buying his claims, (Patricia Wexler for one), you can fight the drying effects of water on skin by cleansing with cold cream, a practice common with European women.
Antibiotics for acne, both topical and oral, used to be the top prescriptions for getting clear skin, but research has revealed that they aren’t the best option for most people today due to something called antibacterial resistance. This is where bacteria mutate, become immune to certain antibiotics, then reproduce offspring that are also immune, creating entire colonies of bacteria that can’t be killed by certain antibiotics.
Several scales exist to grade the severity of acne vulgaris, but no single technique has been universally accepted as the diagnostic standard.[68][69] Cook's acne grading scale uses photographs to grade severity from 0 to 8 (0 being the least severe and 8 being the most severe). This scale was the first to use a standardized photographic protocol to assess acne severity; since its creation in 1979, the scale has undergone several revisions.[69] The Leeds acne grading technique counts acne lesions on the face, back, and chest and categorizes them as inflammatory or non-inflammatory. Leeds scores range from 0 (least severe) to 10 (most severe) though modified scales have a maximum score of 12.[69][70] The Pillsbury acne grading scale simply classifies the severity of the acne from grade 1 (least severe) to grade 4 (most severe).[68][71]
According to Dr. Bailey, the best facial cleansers for acne should have at least one of these key ingredients: salicylic acid, glycolic acid or benzoyl peroxide. Cleansers with these ingredients can penetrate your pores and eliminate pore-clogging impurities—like dead skin cells, makeup, excess oil and bacteria—that irritate skin and make acne worse.

For example, if you have acne on dry skin, you need something gentle enough to cleanse and exfoliate but not dehydrate, like a Neutrogena cleanser. If you have oily skin, you’re looking to exfoliate and combat oil production with a product like Cetaphil. If you have combination skin, you need something that can treat your unique skin and balance it out, like Exposed Skin Care.


Atrophic acne scars have lost collagen from the healing response and are the most common type of acne scar (account for approximately 75% of all acne scars).[31][32] They may be further classified as ice-pick scars, boxcar scars, and rolling scars.[30] Ice-pick scars are narrow (less than 2 mm across), deep scars that extend into the dermis.[31] Boxcar scars are round or ovoid indented scars with sharp borders and vary in size from 1.5–4 mm across.[31] Rolling scars are wider than icepick and boxcar scars (4–5 mm across) and have a wave-like pattern of depth in the skin.[31]

Some people use natural treatments like tea tree oil (works like benzoyl peroxide, but slower) or alpha hydroxy acids (remove dead skin and unclog pores) for their acne care. Not much is known about how well many of these treatments work and their long-term safety. Many natural ingredients are added to acne lotions and creams. Talk to your doctor to see if they’re right for you.
There are two big guns used to take down acne, and they're both great at doing entirely different things. Salicylic acid is a beta hydroxy acid that comes from willow bark and works primarily as an exfoliator, breaking down fatty acids like sebum so your pores don’t clog. (Glycolic acid works similarly but is less effective.) These acids do their thing on comedones — whiteheads, blackheads, and other non-red bumps.
Antibiotics for acne, both topical and oral, used to be the top prescriptions for getting clear skin, but research has revealed that they aren’t the best option for most people today due to something called antibacterial resistance. This is where bacteria mutate, become immune to certain antibiotics, then reproduce offspring that are also immune, creating entire colonies of bacteria that can’t be killed by certain antibiotics.
What's Going On: You might be all too familiar with these, which tend to make their debut when you’re in high school. "Blackheads, like whiteheads, are blocked pores," says Zeichner. What gives them their namesake color, though, is the oil. It's already dark, but blackheads also have a larger opening at the surface than whiteheads do, meaning air can enter and oxidize that oil sitting inside the pore, turning it even darker.
A big acne myth is that you can wash it away. Although you should wash your face in the morning to rid it of any bacteria and saliva that might be lingering from your pillow, and you should wash it at night to clean away the sweat and grime that accumulated, twice a day is plenty. You also shouldn’t spend more than 30 seconds on this part of your skin care routine. Begin with warm water that is not too hot. When you are finished, you can splash your face with cold water to close the pores or use an astringent. Make sure you get a clean towel each time you wash so that you aren’t patting more bacteria onto your clean face. If you use a washcloth to clean your face, make sure you don’t reuse it.
Have you tried treating your acne with no luck? You might simply be using the wrong product for the type you have. Whether you have periodic breakouts or more stubborn cystic acne, there's a solution. We asked Dr. Neal Schultz, an NYC dermatologist, to share the best treatments for every type of acne. Read on for his expert product recommendations, along with some editor favorites, that'll give you clear skin in no time.
One of the most gentle face cleansers we selected is this one from Paula’s Choice. It won’t dehydrate sensitive skin because it has just 0.5% salicylic acid. But it still contains enough to unclog pores and exfoliate dead skin. You’ll hardly know that it’s working because it’s so pleasant to use. The silky texture glides on and lathers away oil and grime. Furthermore, there are no parabens or artificial fragrances in the formula.
One of the best face washes for sensitive skin, this soap-free, fragrance-free, non-comedogenic cleanser works to remove excess oil from your skin without irritation. It’s great for oily and combination skin types, as it cleans and purifies without making the skin taut and dry. Its formula is glycerin-based for a gentle cleanser that won’t provoke even the most sensitive of skin types.

Accutane (isotretinoin) has a mixed reputation, but among dermatologists it’s the finisher for patients with severe acne. “If you have an acne patient that doesn’t respond to anything, [Accutane] can really be a game changer,” board-certified dermatologist Adam Friedman tells SELF. Accutane is an oral retinoid, and it has all the same benefits of a topical retinol but is even more effective.


The third phase of the life cycle of acne is inflammation. At this point, your body’s immune system may deal with the problem, but if it doesn’t, different bacteria can move into the pore. Detecting an enemy bacterial invader, your body responds by emitting white blood cells to the infected area. In some cases, the white blood cells have a difficult time fighting the bacteria, and some die, contributing to the oily buildup and creating pus.
Low concentrations of salicylic acid, like 0.5 percent, are perfect for people who have both acne and sensitive skin. If you have sensitive skin, you know that most of the “best” acne medications just don’t work for you because they are too strong. Products that are too strong for you can cause increased inflammation, which can actually lead to more acne rather than less. Because of this, salicylic acid is our number one recommendation for sensitive skin.
I've been using it now for quite some time (along with a few other Tracie Martyn products and the hyaluronic acid product my dermatologist recommended) and it's my new obsession. My drying, aging skin problems have cleared up. No more flaky skin. No more grease face from Pond's (my long-time love), no more tight skin feeling from the other cleansers I've tried that are really not for dry skin.
Efforts to better understand the mechanisms of sebum production are underway. The aim of this research is to develop medications that target and interfere with the hormones that are known to increase sebum production (e.g., IGF-1 and alpha-melanocyte-stimulating hormone).[10] Additional sebum-lowering medications being researched include topical antiandrogens and peroxisome proliferator-activated receptor modulators.[10] Another avenue of early-stage research has focused on how to best use laser and light therapy to selectively destroy sebum-producing glands in the skin's hair follicles in order to reduce sebum production and improve acne appearance.[10]
Diet. Studies indicate that certain dietary factors, including skim milk and carbohydrate-rich foods — such as bread, bagels and chips — may worsen acne. Chocolate has long been suspected of making acne worse. A small study of 14 men with acne showed that eating chocolate was related to a worsening of symptoms. Further study is needed to examine why this happens and whether people with acne would benefit from following specific dietary restrictions.
Harsh soaps have ingredients that strip your skin of oil will put anyone at risk of pimples and clogged pores due to dry, tightened skin. Almost all body washes, no matter how gentle they claim to be, are designed to remove excess oils from your body quickly and easily. That includes removing dirt and oil from around tougher bodily hairs and pores. But the skin and hair on your face is nothing like the rest of your body. Facial skin is thinner than body skin, even though it has more sebaceous glands (glands that secrete sebum). This makes it more tender, more prone to acne and even more susceptible to aging. Thus, it has to be treated differently than the rest of your body.
Perhaps one of the most popular cleansers for combination skin care on the market today, Boscia's purifying cleansing gel works best for oily to normal skin types. It works by gently cleansing skin without stripping it and adding harsh elements to the skin. It can be a tad drying, so it works best on women with more oily spots than dry spots. You can also use it to cleanse your oily T-zone, but keep it away from your dry spots, where you may want to moisturize more.
“You unfortunately cannot determine the strength of a product strictly by the percentage of its active ingredients because how well a product works depends on how well its inactive ingredients help it penetrate the skin,” explains Dr. Green. “In other words, a 2 percent benzoyl peroxide may be more effective than another brand’s 5 percent benzoyl peroxide because there are other ingredients helping out.”

What it is: You may have heard of tretinoin in reference to "Retin-A" wrinkle treatments. Tretinoin is retinoic acid and vitamin A acid combined, and comes in various strengths in creams, gels, and liquids for topical use on the skin. It is used to treat acne and also to treat sun damaged skin or wrinkles and is usually applied once per day.1Learn more from the U.S. National Library of Medicine.
Considerations: Despite the frequent referencing of an initial flare of acne when starting is tretinoin, there is no scientific evidence to back this up. You should not expect an initial worsening of acne.3-4 Exposure to sunlight should be minimized as you may be more sensitive to its rays. Ask your doctor before using other medication on the skin, especially anything containing sulfur, resorcinol, or salicylic acid, as the combination may be too irritating. Abrasive soaps and cleansers should be used with caution for the same reason. Side effects can include skin irritation, swelling, lightening or darkening of the skin, an increase in acne sores, excessive redness, and crusted or blistered skin.
Acne, also known as acne vulgaris, is a long-term skin disease that occurs when hair follicles are clogged with dead skin cells and oil from the skin.[10] It is characterized by blackheads or whiteheads, pimples, oily skin, and possible scarring.[1][2][11] It primarily affects areas of the skin with a relatively high number of oil glands, including the face, upper part of the chest, and back.[12] The resulting appearance can lead to anxiety, reduced self-esteem and, in extreme cases, depression or thoughts of suicide.[3][4]
