There are a number of mild chemical peels available over the counter, but acne scar removal requires a stronger peel typically administered by a doctor or dermatologist. Trichloroacetic acid (TCA) peels are slightly stronger than alpha hydroxy acid (AHA) peels and may be used for acne scar treatment. The strongest type, phenol peels, may cause significant swelling and require up to two weeks of recovery time at home. Neither are recommended for people with active severe acne.
Acne vulgaris and its resultant scars have been associated with significant social and academic difficulties that can last into adulthood, including difficulties obtaining employment.[31][178] 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.[166] 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.[166]
Medical conditions that commonly cause a high-androgen state, such as polycystic ovary syndrome, congenital adrenal hyperplasia, and androgen-secreting tumors, can cause acne in affected individuals.[45][46] Conversely, people who lack androgenic hormones or are insensitive to the effects of androgens rarely have acne.[45] An increase in androgen and oily sebum synthesis may be seen during pregnancy.[46][47] Acne can be a side effect of testosterone replacement therapy or of anabolic steroid use.[1][48] Over-the-counter bodybuilding and dietary supplements are commonly found to contain illegally added anabolic steroids.[1][49]
Exercise not only helps you with fitness, but it can help reduce acne-prone skin irritations. That’s right, add its use on how to get rid of pimples to the list of exercise benefits. Exercise offers stress relief while getting the blood circulating. This blood-pumping activity sends oxygen to your skin cells, which helps remove dead cells from the body.
The Pore Normalizing Cleanser is designed just to cleanse, not treat, which is a good thing: The Nurse Practitioner study emphasizes the importance of washing with mild cleansers in conjunction with topical acne medications to combat or avoid excessive skin irritation. This one is water-based and fragrance-free, and uses sodium laureth sulfate (as opposed to its harsh cousin sodium lauryl sulfate) to eliminate any chance for irritation.
The recognition and characterization of acne progressed in 1776 when Josef Plenck (an Austrian physician) published a book that proposed the novel concept of classifying skin diseases by their elementary (initial) lesions.[164] In 1808 the English dermatologist Robert Willan refined Plenck's work by providing the first detailed descriptions of several skin disorders using a morphologic terminology that remains in use today.[164] Thomas Bateman continued and expanded on Robert Willan's work as his student and provided the first descriptions and illustrations of acne accepted as accurate by modern dermatologists.[164] Erasmus Wilson, in 1842, was the first to make the distinction between acne vulgaris and rosacea.[165] The first professional medical monograph dedicated entirely to acne was written by Lucius Duncan Bulkley and published in New York in 1885.[166][167]

If one of you is a night owl and the other an early riser, bedtime can become a source of conflict. It’s hard for a light sleeper to be jostled by their partner coming to bed four hours after them. Talk to your partner about negotiating some compromises. If you’re finding it difficult to agree on a bedtime, negotiate with your partner. Don’t come to bed before or after a certain time, giving the early bird a chance to fully fall asleep before the other comes in. Consider giving the night owl an eye mask to allow them to stay in bed while their partner gets up to start the day.

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]
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.”

Inflammatory Acne: Inflammatory acne is red bumps and pustules, not whiteheads, blackheads and comedones. It doesn't necessarily start as them, either. It arises on its own. Whiteheads, blackheads or comedones that become inflamed can be painful and unsightly. Persistent inflammatory acne may require treatment by a physician or dermatologist, in addition to over-the-counter acne remedies.


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]

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]
Light therapy is a treatment method that involves delivering certain specific wavelengths of light to an area of skin affected by acne. Both regular and laser light have been used. When regular light is used immediately following the application of a sensitizing substance to the skin such as aminolevulinic acid or methyl aminolevulinate, the treatment is referred to as photodynamic therapy (PDT).[10][129] PDT has the most supporting evidence of all light therapies.[78] Many different types of nonablative lasers (i.e., lasers that do not vaporize the top layer of the skin but rather induce a physiologic response in the skin from the light) have been used to treat acne, including those that use infrared wavelengths of light. Ablative lasers (such as CO2 and fractional types) have also been used to treat active acne and its scars. When ablative lasers are used, the treatment is often referred to as laser resurfacing because, as mentioned previously, the entire upper layers of the skin are vaporized.[140] Ablative lasers are associated with higher rates of adverse effects compared with nonablative lasers, with examples being postinflammatory hyperpigmentation, persistent facial redness, and persistent pain.[8][141][142] Physiologically, certain wavelengths of light, used with or without accompanying topical chemicals, are thought to kill bacteria and decrease the size and activity of the glands that produce sebum.[129] The evidence for light therapy as a treatment for acne is weak and inconclusive.[8][143] Disadvantages of light therapy can include its cost, the need for multiple visits, time required to complete the procedure(s), and pain associated with some of the treatment modalities.[10] Various light therapies appear to provide a short-term benefit, but data for long-term outcomes, and for outcomes in those with severe acne, are sparse;[144] it may have a role for individuals whose acne has been resistant to topical medications.[10] A 2016 meta-analysis was unable to conclude whether light therapies were more beneficial than placebo or no treatment, nor how long potential benefits lasted.[145] Typical side effects include skin peeling, temporary reddening of the skin, swelling, and postinflammatory hyperpigmentation.[10]

Contrary to the marketing promises of “blemish banishers” and “zit zappers,” immediate results are not the trademark of acne treatments — a frustrating truth to anyone suffering through a breakout. And while pimples are personal (your stress-induced spots will look and act differently than your best friend’s breakout), the best acne treatments will include a regimen of products to hit all of acne’s root causes. We tested 43 kits to find the most well-rounded breakout-fighting solutions on the market.


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.
