However, unlike the previously discussed treatment options, gender plays a role in how effective dapsone will be. Research has shown11 that female patients who use it get a much better response than male patients. It’s also a slow-working treatment. Studies among adolescents have shown that it is very effective, but it may take up to 12 weeks for improvements to show up, with more improvements taking place with continued use.

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]

Microneedling is a procedure in which an instrument with multiple rows of tiny needles is rolled over the skin to elicit a wound healing response and stimulate collagen production to reduce the appearance of atrophic acne scars in people with darker skin color.[140] Notable adverse effects of microneedling include postinflammatory hyperpigmentation and tram track scarring (described as discrete slightly raised scars in a linear distribution similar to a tram track). The latter is thought to be primarily attributable to improper technique by the practitioner, including the use of excessive pressure or inappropriately large needles.[140][146]
Retinoids are medications which reduce inflammation, normalize the follicle cell life cycle, and reduce sebum production.[44][83] They are structurally related to vitamin A.[83] 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.[35]

Benzoyl peroxide is an antibacterial ingredient, and it’s very effective at killing the P. acnes bacteria that causes breakouts. But benzoyl isn’t without its downsides. The leave-on creams and cleansing treatments can dry out sensitive skin types and bleach clothing if you aren’t careful. Board-certified dermatologist Eric Meinhardt, M.D., previously told SELF that it's best to stick to formulations that have no more than 2 percent of benzoyl peroxide listed on the active ingredients chart; stronger concentrations are harder on your skin without being any tougher on bacteria.

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]

Retinol: Retinol is simply another word for vitamin A, sort of like how we call vitamin B7 “biotin.” It’s important that our bodies get systemic vitamin A through our diet for good vision, a strong immune system, and general organ function, but some research suggests that vitamin A could have a positive impact on the skin when applied to it directly. The problem is, regular retinol doesn’t actually do much for acne. That’s because the retinoic acid found in retinol isn’t always activated when left to its own devices. We typically have to activate the retinoic acid synthetically through the creation of various medications.
Hormonal treatments for acne such as combined birth control pills and antiandrogens may be considered a first-line therapy for acne under a number of circumstances, including when contraception is desired, when known or suspected hyperandrogenism is present, when acne occurs in adulthood, when acne flares premenstrually, and when symptoms of significant sebum production (seborrhea) are co-present.[128] Hormone therapy is effective for acne even in women with normal androgen levels.[128]

The earliest pathologic change is the formation of a plug (a microcomedone), which is driven primarily by excessive growth, reproduction, and accumulation of skin cells in the hair follicle.[1] In normal skin, the skin cells that have died come up to the surface and exit the pore of the hair follicle.[10] However, increased production of oily sebum in those with acne causes the dead skin cells to stick together.[10] The accumulation of dead skin cell debris and oily sebum blocks the pore of the hair follicle, thus forming the microcomedone.[10] This is further exacerbated by the biofilm created by P. acnes within the hair follicle.[44] If the microcomedone is superficial within the hair follicle, the skin pigment melanin is exposed to air, resulting in its oxidation and dark appearance (known as a blackhead or open comedo).[1][10][19] In contrast, if the microcomedone occurs deep within the hair follicle, this causes the formation of a whitehead (known as a closed comedo).[1][10]
