It is widely suspected that the anaerobic bacterial species Cutibacterium acnes (formerly Propionibacterium. acnes) contributes to the development of acne, but its exact role is not well understood.[2] There are specific sub-strains of C. acnes associated with normal skin, and moderate or severe inflammatory acne.[50] It is unclear whether these undesirable strains evolve on-site or are acquired, or possibly both depending on the person. These strains have the capability of changing, perpetuating, or adapting to the abnormal cycle of inflammation, oil production, and inadequate sloughing of dead skin cells from acne pores. Infection with the parasitic mite Demodex is associated with the development of acne.[30][51] It is unclear whether eradication of the mite improves acne.[51]
Wear sunscreen everyday and do not tan. Ultraviolet Radiation is the number one cause of premature aging. It also leads to skin cancer in high enough doses. Treat the sun like the death ray that it is. Exposing your skin to harmful UVA and UVB rays damages skin and prolongs post inflammatory erythema(PIE)--red acne marks, as the sunlight stimulates pigment-producing cells.

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][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]

In general, it is recommended that people with acne do not wash affected skin more than twice daily.[15] For people with acne and sensitive skin, a fragrance free moisturizer may be used to reduce irritation. Skin irritation from acne medications typically peaks at two weeks after onset of use and tends to improve with continued use.[15] Cosmetic products that specifically say "non-comedogenic", "oil-free", and "won't clog pores" are recommended.[15]
Pharaohs are recorded as having had acne, which may be the earliest known reference to the disease. Since at least the reign of Cleopatra (69–30 BC), the application of sulfur to the skin has been recognized as a useful treatment for acne.[162] The sixth-century Greek physician Aëtius of Amida is credited with coining the term "ionthos" (ίονθωξ,) or "acnae", which is believed to have been a reference to facial skin lesions that occur during "the 'acme' of life" (puberty).[163]
Sometimes birth control alone isn’t enough to really make a difference in hormonal acne. That’s when your doctor might recommend adding in an androgen blocker such as Spironalactone. Spiro (as it’s called) minimizes the amount of androgen hormones in circulation by blocking the receptors that bind with testosterone. When these pills are taken at the same time as an oral contraceptive, 90 percent of women see an improvement in breakouts, according to Linkner. The drug is sometimes prescribed to women with PCOS (polycystic ovarian syndrome) to relieve androgen-related symptoms like excessive hair growth, hypertension, oily skin, and acne.
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]
The three-piece set doesn’t come with a sun protection treatment, but Paula’s Choice has one in the line, the Clear Ultra-Light Daily Fluid SPF 30+. “Sun protection is really important, especially with acneic skin,” says Townsend. “In many cases, stronger acne products can make the skin photosensitive to the sun.” This isn’t your normal gloppy white sunscreen. Its fluid formula slips over tender skin, doesn’t need a ton of rubbing in, and also leaves a mattifying finish.

Alternative and integrative medicine approaches used in the treatment of acne include fish oil, brewer's yeast, probiotics, oral zinc and topical tea tree oil. More research is needed to establish the potential effectiveness and long-term safety of these and other integrative approaches, such as biofeedback and traditional Chinese medicine. Talk with your doctor about the pros and cons of specific treatments before you try them.
Retinoids are medications which reduce inflammation, normalize the follicle cell life cycle, and reduce sebum production.[45][82] They are structurally related to vitamin A.[82] Studies show they are underprescribed by primary care doctors and dermatologists.[15] The retinoids appear to influence the cell life cycle in the follicle lining. This helps prevent the accumulation of skin cells within the hair follicle that can create a blockage. They are a first-line acne treatment,[1] especially for people with dark-colored skin, and are known to lead to faster improvement of postinflammatory hyperpigmentation.[36]
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.
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]

Complementary therapies have been investigated for treating people with acne.[150] Low-quality evidence suggests topical application of tea tree oil or bee venom may reduce the total number of skin lesions in those with acne.[150] Tea tree oil is thought to be approximately as effective as benzoyl peroxide or salicylic acid, but has been associated with allergic contact dermatitis.[1] Proposed mechanisms for tea tree oil's anti-acne effects include antibacterial action against C. acnes, and anti-inflammatory properties.[65] Numerous other plant-derived therapies have been observed to have positive effects against acne (e.g., basil oil and oligosaccharides from seaweed); however, few studies have been performed, and most have been of lower methodological quality.[151] There is a lack of high-quality evidence for the use of acupuncture, herbal medicine, or cupping therapy for acne.[150]

Many treatment options for acne are available, including lifestyle changes, medications, and medical procedures. Eating fewer simple carbohydrates such as sugar may help.[7] Treatments applied directly to the affected skin, such as azelaic acid, benzoyl peroxide, and salicylic acid, are commonly used.[8] Antibiotics and retinoids are available in formulations that are applied to the skin and taken by mouth for the treatment of acne.[8] However, resistance to antibiotics may develop as a result of antibiotic therapy.[16] Several types of birth control pills help against acne in women.[8] Isotretinoin pills are usually reserved for severe acne due to greater potential side effects.[8][17] Early and aggressive treatment of acne is advocated by some in the medical community to decrease the overall long-term impact to individuals.[4]
Shah often recommends over-the-counter retinols or prescription retinoids to her acne-prone patients. “I find that compared to other treatments they are beneficial for not just treating acne but also preventing new acne from forming as they help prevent that initial stage of the follicle getting clogged,” she says. “They can also help with some of the post acne [problems] such as hyperpigmentation.” But keep in mind if you have sensitive skin (or eczema or rosacea), a prescription retinoid might be too strong an option. However, your dermatologist can recommend an over-the-counter retinol with a low concentration (0.1 to 0.25 percent), which might be better tolerated. Retinol also isn’t a quick fix. It takes time to see results, and it’s something you’ll have to keep using to maintain its benefits. Shah also mentions that retinol plays well with other acne treatments on the list. "Retinol can be combined with other over-the-counter or prescription medications such as benzoyl peroxide, topical antibiotics, and oral medications. The right combination depends on the severity of the acne and your skin type."
Doxycycline is another of the tetracyclines that's equally effective in treating acne. It comes in generic versions and also as the branded Doryx and Acticlate which are easier on the stomach. Originally FDA approved for the treatment of rosacea, Oracea is a non antibiotic dose of doxycycline that is often used as an acne treatment, as well. Taken orally, it can be used as solo therapy or in combination with a topical acne treatment regimen. More severe cases of acne might need higher doses of doxycycline, but since Oracea is not an antibiotic, many patients can be "down-graded" to Oracea after improvement and it's suitable for longterm use as it doesn't cause antibiotic resistance.
Every expert we spoke with said the most critical part of combating acne is combating it every day. “The only way to make any medication work is to use it on a daily basis,” says Dr. Green. Aesthetician and Rodan + Fields Consultant, Jessica Fitz Patrick emphasizes that it really comes down to what you can maintain for the long term: “Kits are great because they take out all the guesswork -- you just follow the instructions. But if four steps is going to be too many for you to keep up week after week, you’ll be better off finding one that has fewer treatments.”
Antibiotics. These work by killing excess skin bacteria and reducing redness. For the first few months of treatment, you may use both a retinoid and an antibiotic, with the antibiotic applied in the morning and the retinoid in the evening. The antibiotics are often combined with benzoyl peroxide to reduce the likelihood of developing antibiotic resistance. Examples include clindamycin with benzoyl peroxide (Benzaclin, Duac, Acanya) and erythromycin with benzoyl peroxide (Benzamycin). Topical antibiotics alone aren't recommended.
