What's Going On: Do you tend to get these at the same time every month — say, just before you get your period? Because these are the work of fluctuating hormones, says Joshua Zeichner, a dermatologist and the director of cosmetic and clinical research in dermatology at Mount Sinai Hospital in New York City. Hormones can put oil production into overdrive, and having an excess of it means that it’s more likely to settle in your pores and cause zits.

Some people swear by the disinfecting power of tea tree oil for acne treatment. It can be applied either full strength or slightly diluted with water directly onto pimples. Use a small amount on a clean cotton swab or cotton pad and dab on the affected areas immediately after cleansing. Because tea tree oil can be drying, you might choose to use both tea tree oil and coconut oil for acne as part of your clear skin regimen.

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]


Therefore, it is very important that you wear sunscreen everyday, with an SPF of 30.Of note, after SPF 30, there are decreasing marginal returns in UVB protection. The % of UVB protection as a function of SPF Value is a log graph and plateaus after SPF 30. Therefore, there is not much difference in protection between SPF 40 and 50. Sunscreens with an SPF 100 are banned in some countries.

Bacteria. Excess sebum clogs the openings to hair follicles -- especially those on the face, neck, chest, and back. Bacteria grow in these clogged follicles. This makes blackheads or whiteheads, also known as ''comedones,'' form on the skin's surface. Sometimes, this clogging causes the follicle wall to break under the pressure of this buildup. When this happens, sebum leaks into nearby tissues and forms a pustule or a papule -- this is called inflammatory acne. Larger, tender pustules are called nodules.

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]
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 C. acnes, and normalizing skin cell shedding and sebum production in the pore to prevent blockage.[15] Common treatments include topical therapies such as antibiotics, benzoyl peroxide, and retinoids, and systemic therapies including antibiotics, hormonal agents, and oral retinoids.[20][76]

Warning: Sulfur smells like rotten eggs. But it is an effective ingredient at drying up pus-filled pimples and whiteheads (you’ve gotta take the good with the bad). It works by sucking up the oil. Sulfur is typically mixed with other active ingredients to get the most efficacy and fragrances to mask the strong scent. You can often find it in masks and spot treatments.

Back acne (sometimes called "bacne") is a potentially embarrassing and sometimes painful condition where clogged hair follicles on the back cause pimples and blackheads. Back acne can be caused by the same factors as other types of acne: diet, hormones, certain medications, genetics or any combination thereof. But when you're considering how to get rid of back acne, also remember that most people have their back covered the majority of the day. The clothing we wear matters, and the way in which we wash the skin on our back is key for clear skin, the whole body over. Learn more about common back acne causes, the best acne products for your body, and how to prevent acne on the back from returning in this section.


Decreased levels of retinoic acid in the skin may contribute to comedo formation. To address this deficiency, methods to increase the skin's production of retinoid acid are being explored.[10] A vaccine against inflammatory acne has shown promising results in mice and humans.[50][180] Some have voiced concerns about creating a vaccine designed to neutralize a stable community of normal skin bacteria that is known to protect the skin from colonization by more harmful microorganisms.[181]

The main hormonal driver of oily sebum production in the skin is dihydrotestosterone.[1] Another androgenic hormone responsible for increased sebaceous gland activity is DHEA-S. Higher amounts of DHEA-S are secreted during adrenarche (a stage of puberty), and this leads to an increase in sebum production. In a sebum-rich skin environment, the naturally occurring and largely commensal skin bacterium C. acnes readily grows and can cause inflammation within and around the follicle due to activation of the innate immune system.[10] C. acnes triggers skin inflammation in acne by increasing the production of several pro-inflammatory chemical signals (such as IL-1α, IL-8, TNF-α, and LTB4); IL-1α is known to be essential to comedo formation.[45]


Side effects include increased skin photosensitivity, dryness, redness and occasional peeling.[80] Sunscreen use is often advised during treatment, to prevent sunburn. Lower concentrations of benzoyl peroxide are just as effective as higher concentrations in treating acne but are associated with fewer side effects.[79][81] Unlike antibiotics, benzoyl peroxide does not appear to generate bacterial antibiotic resistance.[80]
Combination therapy—using medications of different classes together, each with a different mechanism of action—has been demonstrated to be a more efficacious approach to acne treatment than monotherapy.[10][47] The use of topical benzoyl peroxide and antibiotics together has been shown to be more effective than antibiotics alone.[10] Similarly, using a topical retinoid with an antibiotic clears acne lesions faster than the use of antibiotics alone.[10] Frequently used combinations include the following: antibiotic and benzoyl peroxide, antibiotic and topical retinoid, or topical retinoid and benzoyl peroxide.[47] The pairing of benzoyl peroxide with a retinoid is preferred over the combination of a topical antibiotic with a retinoid since both regimens are effective but benzoyl peroxide does not lead to antibiotic resistance.[10]
Like baby acne, eczema is very common in newborns, but it’s usually caused by dry (not oily) skin. Mild eczema can cause lots of small bumps, similar to baby acne. Since it often starts on the cheeks, it’s easy to confuse with baby acne. But, if it spreads into a rash that covers the skin or develops in other areas of your baby’s body, such as the folds of his elbows and knees, then it’s probably eczema, not acne. Eczema isn’t usually serious. You can treat it by using a gentle hydrating lotion on your baby’s skin after bathtime.
The two laser treatment options above are great for acne scar removal, but aren't generally recommended as acne treatment. If you're still experiencing active acne breakouts and wondering how to get rid of acne with laser treatments, check out photodynamic therapy. It combats active moderate to severe acne while also diminishing older acne scars by using light energy to activate a powerful acne-fighting solution. Patients may require 2 or 3 treatments over several weeks and should expect some redness, peeling and sun sensitivity. This treatment will cost between $2000 to $3500 per series.

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]

Recommended therapies for first-line use in acne vulgaris treatment include topical retinoids, benzoyl peroxide, and topical or oral antibiotics.[77] Procedures such as light therapy and laser therapy are not considered to be first-line treatments and typically have an adjunctive role due to their high cost and limited evidence of efficacy.[76] Medications for acne work by targeting the early stages of comedo formation and are generally ineffective for visible skin lesions; improvement in the appearance of acne is typically expected between eight and twelve weeks after starting therapy.[15]
Acne vulgaris is a chronic skin disease of the pilosebaceous unit and develops due to blockages in the skin's hair follicles. These blockages are thought to occur as a result of the following four abnormal processes: a higher than normal amount of oily sebum production (influenced by androgens), excessive deposition of the protein keratin leading to comedo formation, colonization of the follicle by Cutibacterium acnes (C. acnes) bacteria, and the local release of pro-inflammatory chemicals in the skin.[50]

Use oil-free makeup. If you wear makeup, you may be stuck in a vicious cycle of covering up acne while simultaneously causing it with your cover-up usage. Find acne-fighting oil-free mineral makeup to help prevent worsening your acne while simply trying to hide it. Power foundations are also recommended. When possible, avoid wearing make-up at all though as it clogs your pores over the course of the day.

The birth control pill is another option for women suffering hormonal acne. Four types of birth control pills have been approved by the FDA for use as acne treatment, and all four are combination pills that contain both estrogen and progesterone. Talk to your doctor about how to get rid of acne using birth control and keep in mind that Ortho Tri-cyclen, Estrostep YAZ and Beyaz are the only four brands specifically FDA approved as acne remedies.

Acne mechanica is caused by heat, friction, and pressure against the skin, often the result of wearing sports gear such as a helmet or baseball cap. It is sometimes called "sports-induced acne" because it occurs frequently in athletes. Preventive measures include wearing an absorbent material under sports equipment and showering immediately after activity.
