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]
For adult women, spironolactone is preferred over oral antibiotics since women with adult acne will likely have this condition at least until menopause, and starting and stopping an oral antibiotic over many years could potentially contribute to drug resistance and decreased microbial response. Spironolactone is completely safe to use on an ongoing basis once the correct dose is determined by the treating physician. It is advisable to check a potassium level at the 150mg dosing.

Its formula is glycerin-based for a gentle cleanser that won’t provoke even the most sensitive of skin types.
A major mechanism of acne-related skin inflammation is mediated by P. acnes's ability to bind and activate a class of immune system receptors known as toll-like receptors (TLRs), especially TLR2 and TLR4.[44][64][65] Activation of TLR2 and TLR4 by P. acnes leads to increased secretion of IL-1α, IL-8, and TNF-α.[44] Release of these inflammatory signals attracts various immune cells to the hair follicle including neutrophils, macrophages, and Th1 cells.[44] IL-1α stimulates increased skin cell activity and reproduction, which in turn fuels comedo development.[44] Furthermore, sebaceous gland cells produce more antimicrobial peptides, such as HBD1 and HBD2, in response to binding of TLR2 and TLR4.[44]

Some people use natural treatments like tea tree oil (works like benzoyl peroxide, but slower) or alpha hydroxy acids (remove dead skin and unclog pores) for their acne care. Not much is known about how well many of these treatments work and their long-term safety. Many natural ingredients are added to acne lotions and creams. Talk to your doctor to see if they’re right for you.
Active Ingredients Check the product label for key active ingredients like salicylic acid or benzoyl peroxide, advises dermatologist Sandy Skotnicki, MD, founder of Toronto's Bay Dermatology Centre and author of the skincare book Beyond Soap. Other ingredients to look for include oils that can help to moisturize skin — just make sure the package says non-comedogenic, which means that it won’t clog pores.

The key is patience — don’t pick up a new cleanser and expect to see dramatic results right away. While you may be able to spot-treat a pimple or two overnight, it can take weeks before you really see a difference from switching cleansers. “It’s about trying different brands with different strengths and giving it sufficient time to work,” says Anna Avaliani, MD, a cosmetic and laser skin care specialist in NYC.
