Flutamide, a pure antagonist of the androgen receptor, is effective in the treatment of acne in women.[100][107] It has generally been found to reduce symptoms of acne by 80 or 90% even at low doses, with several studies showing complete acne clearance.[100][108][109] In one study, flutamide decreased acne scores by 80% within 3 months, whereas spironolactone decreased symptoms by only 40% in the same time period.[109][110][111] In a large long-term study, 97% of women reported satisfaction with the control of their acne with flutamide.[112] Although effective, flutamide has a risk of serious liver toxicity, and cases of death in women taking even low doses of the medication to treat androgen-dependent skin and hair conditions have occurred.[113] As such, the use of flutamide for acne has become increasingly limited,[112][114][115] and it has been argued that continued use of flutamide for such purposes is unethical.[113] Bicalutamide, a pure androgen receptor antagonist with the same mechanism as flutamide and with comparable or superior antiandrogenic efficacy but without its risk of liver toxicity, is a potential alternative to flutamide in the treatment of androgen-dependent skin and hair conditions in women.[105][116][117][118]
C. acnes also provokes skin inflammation by altering the fatty composition of oily sebum.[45] Oxidation of the lipid squalene by C. acnes is of particular importance. Squalene oxidation activates NF-κB (a protein complex) and consequently increases IL-1α levels.[45] Additionally, squalene oxidation leads to increased activity of the 5-lipoxygenase enzyme responsible for conversion of arachidonic acid to leukotriene B4 (LTB4).[45] LTB4 promotes skin inflammation by acting on the peroxisome proliferator-activated receptor alpha (PPARα) protein.[45] PPARα increases activity of activator protein 1 (AP-1) and NF-κB, thereby leading to the recruitment of inflammatory T cells.[45] The inflammatory properties of C. acnes can be further explained by the bacterium's ability to convert sebum triglycerides to pro-inflammatory free fatty acids via secretion of the enzyme lipase.[45] These free fatty acids spur production of cathelicidin, HBD1, and HBD2, thus leading to further inflammation.[45]

Atrophic acne scars have lost collagen from the healing response and are the most common type of acne scar (account for approximately 75% of all acne scars).[32][33] They may be further classified as ice-pick scars, boxcar scars, and rolling scars.[31] Ice-pick scars are narrow (less than 2 mm across), deep scars that extend into the dermis.[32] Boxcar scars are round or ovoid indented scars with sharp borders and vary in size from 1.5–4 mm across.[32] Rolling scars are wider than icepick and boxcar scars (4–5 mm across) and have a wave-like pattern of depth in the skin.[32]
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.[6]
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.[127] Hormone therapy is effective for acne even in women with normal androgen levels.[127]
Acne treatment that you apply to the skin: Most acne treatments are applied to the skin. Your dermatologist may call this topical treatment. There are many topical acne treatments. Some topicals help kill the bacteria. Others work on reducing the oil. The topical medicine may contain a retinoid, prescription-strength benzoyl peroxide, antibiotic, or even salicylic acid. Your dermatologist will determine what you need.

Salicylic acid is a topically applied beta-hydroxy acid that stops bacteria from reproducing and has keratolytic properties.[131][132] It opens obstructed skin pores and promotes shedding of epithelial skin cells.[131] Salicylic acid is known to be less effective than retinoid therapy.[20] Dry skin is the most commonly seen side effect with topical application, though darkening of the skin has been observed in individuals with darker skin types.[1]
Oral isotretinoin is very effective. But because of its potential side effects, doctors need to closely monitor anyone they treat with this drug. Potential side effects include ulcerative colitis, an increased risk of depression and suicide, and severe birth defects. In fact, isotretinoin carries such serious risk of side effects that all people receiving isotretinoin must participate in a Food and Drug Administration-approved risk management program.
