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. The use of topical benzoyl peroxide and antibiotics together has been shown to be more effective than antibiotics alone. Similarly, using a topical retinoid with an antibiotic clears acne lesions faster than the use of antibiotics alone. Frequently used combinations include the following: antibiotic and benzoyl peroxide, antibiotic and topical retinoid, or topical retinoid and benzoyl peroxide. 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.
A nodule is an abnormal tissue growth which can either develop just below the skin or anywhere within the skin’s three layers (the epidermis, dermis, and subcutaneous tissue). Nodules commonly form in regions such as the face, neck, armpits, and groin, although they can also develop on internal organs such as the lungs, thyroid, and lymph nodes. They create solid, raised lumps that are more than 1 to 2 centimeters in diameter, with the potential to reach up to the size of a hazelnut. Nodules are hard and firm to the touch, unlike cysts whose pus makes them softer to the touch. This type of severe acne should be consulted by a doctor, as it might be indicative of a more serious condition.
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.”
A BHA product often cited includes salicylic acid, it must be between a pH between 3 and 4 to work. A BHA works to slough (to get rid of) off dead skin cells and encourage new skin growth. As a result, you may experience dry skin and scaliness around your acne, but this will dissipate over time as your skin begins to regenerate faster. Use this in a cleanser or spot treatment daily on the acne-affected areas of your skin.
Any acne treatment is a weeks-long experiment that you’re conducting with your skin. Acne is slow to heal, and in some cases, it can get worse before it gets better (nearly every benzoyl peroxide product we looked at emphasized the likeliness of irritating acne further, and starting off with a lighter application). April W. Armstrong, a doctor at the University of California Davis Health System, recommends waiting at least one month before you deem a product ineffective.
While you can certainly benefit from a great skin-care regimen, "in cystic acne, usually you need internal treatment," he says. "Topical medications usually don't work. Accutane is a great miracle cure for really bad cystic acne, but most people with cystic acne will improve with oral antibiotics — sometimes for two weeks, sometimes for three weeks."
Acne inversa (L. invertō, "upside down") and acne rosacea (rosa, "rose-colored" + -āceus, "forming") are not true forms of acne and respectively refer to the skin conditions hidradenitis suppurativa (HS) and rosacea. Although HS shares certain common features with acne vulgaris, such as a tendency to clog skin follicles with skin cell debris, the condition otherwise lacks the defining features of acne and is therefore considered a distinct skin disorder.
Cystic acne is the most severe form of acne vulgaris and can be caused by a variety of factors. This type of acne sees painful lesions develop deep within the skin, which could result in permanent scarring or hyperpigmentation. Cystic acne is easily diagnosed due it its pronounced, inflamed lesions. However, you should consult a dermatologist to rule out other skin conditions which might mimic acne such as rosacea, psoriasis or perioral dermatitis.

Dapsone has shown efficacy against inflammatory acne but is generally not a first-line topical antibiotic due to higher cost and lack of clear superiority over other antibiotics. It is sometimes a preferred therapy in women or for people with sensitive or darker toned skin. Topical dapsone is not recommended for use with benzoyl peroxide due to yellow-orange skin discoloration with this combination. While minocycline is shown to be an effective acne treatment, it is no longer recommended as a first-line antibiotic due to a lack of evidence that it is better than other treatments, and concerns of safety compared to other tetracyclines.
Fractional laser treatment is less invasive than ablative laser treatment, as it targets only a fraction of the skin at a time. Fractional lasers penetrate the top skin layers, where its light energy stimulates collagen production and resurfaces the top layer of the epidermis. Treatments typically last between 15 and 45 minutes and effects become visible in 1 to 3 weeks.
Clascoterone is a topical antiandrogen which has demonstrated effectiveness in the treatment of acne in both males and females and is currently in the late stages of clinical development. It has shown no systemic absorption or associated antiandrogenic side effects. In a direct head-to-head comparison, clascoterone showed greater effectiveness than topical isotretinoin. 5α-Reductase inhibitors such as finasteride and dutasteride may be useful for the treatment of acne in both males and females, but have not been thoroughly evaluated for this purpose. In addition, the high risk of birth defects with 5α-reductase inhibitors limits their use in women. However, 5α-reductase inhibitors can be combined with birth control pills to prevent pregnancy, and are frequently used to treat excessive hair in women. There is no evidence as of 2010 to support the use of cimetidine or ketoconazole in the treatment of acne.
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.
Sugar: For starters, sugar can use up your valuable acne-fighting minerals, particularly zinc because it’s used to process the sugar you consume. Sugar also causes a spike in blood sugar level, leading to high insulin levels, which creates increased sebum production and blocked pores. Additionally, studies show that sugar also has an inflammatory effect which can worsen existing acne. Steer clear of sweets like cookies and cakes, but don’t worry – chocolate is considered safe for skin.
Acne vulgaris and its resultant scars have been associated with significant social and academic difficulties that can last into adulthood, including difficulties obtaining employment. 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. 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.
In general, it is recommended that people with acne do not wash affected skin more than twice daily. 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. Cosmetic products that specifically say "non-comedogenic", "oil-free", and "won't clog pores" are recommended.
Acne medications work by reducing oil production, speeding up skin cell turnover, fighting bacterial infection or reducing inflammation — which helps prevent scarring. With most prescription acne drugs, you may not see results for four to eight weeks, and your skin may get worse before it gets better. It can take many months or years for your acne to clear up completely.
