Postinflammatory hyperpigmentation (PIH) is usually the result of nodular acne lesions. These lesions often leave behind an inflamed darkened mark after the original acne lesion has resolved. This inflammation stimulates specialized pigment-producing skin cells (known as melanocytes) to produce more melanin pigment which leads to the skin's darkened appearance.[35] People with darker skin color are more frequently affected by this condition.[36] Pigmented scar is a common term used for PIH, but is misleading as it suggests the color change is permanent. Often, PIH can be prevented by avoiding any aggravation of the nodule, and can fade with time. However, untreated PIH can last for months, years, or even be permanent if deeper layers of skin are affected.[37] Even minimal skin exposure to the sun's ultraviolet rays can sustain hyperpigmentation.[35] Daily use of SPF 15 or higher sunscreen can minimize such a risk.[37]
Spironolactone is an androgen blocker. It can be used to treat hormonal acne in women (only) by reducing the production of androgens (male hormones) in a woman's body, which can then reduce oil production in the skin. If you're wondering how to get rid of acne overnight, keep in mind that aldactone can take up to three months to start taking effect.
But the side effects of targeted breakout cream treatments aren’t always worth it. “So many products instruct consumers to use benzoyl peroxide spot treat red bumps and pustules. I don’t recommend it,” says Dr. Lawrence Green, board-certified dermatologist and assistant clinical professor of dermatology at George Washington University. Such high concentrations of benzoyl peroxide cause added irritation and inflammation to already sensitive skin, so with this in mind, we cut kits that included spot treatments.

Dermal or subcutaneous fillers are substances injected into the skin to improve the appearance of acne scars. Fillers are used to increase natural collagen production in the skin and to increase skin volume and decrease the depth of acne scars.[146] Examples of fillers used for this purpose include hyaluronic acid; poly(methyl methacrylate) microspheres with collagen; human and bovine collagen derivatives, and fat harvested from the person's own body (autologous fat transfer).[146]
Medical conditions that commonly cause a high-androgen state, such as polycystic ovary syndrome, congenital adrenal hyperplasia, and androgen-secreting tumors, can cause acne in affected individuals.[45][46] Conversely, people who lack androgenic hormones or are insensitive to the effects of androgens rarely have acne.[45] An increase in androgen and oily sebum synthesis may be seen during pregnancy.[46][47] Acne can be a side effect of testosterone replacement therapy or of anabolic steroid use.[1][48] Over-the-counter bodybuilding and dietary supplements are commonly found to contain illegally added anabolic steroids.[1][49]
Dermatologists aren’t sure why azelaic acid is so effective at clearing up inflammation, but it’s often used as an option for sensitive skin or pregnant patients. Linkner says the ingredient is good at treating malasma, acne, and rosacea. Your dermatologist can prescribe a foam product with azelaic acid, and you can also find beauty products with very small amounts of this active ingredient.
1. Topical Treatment: This refers to acne medications which are applied directly onto the skin, such as creams, gels, serums and ointments. Topical treatments can be found over-the-counter (OTC) or at a pharmacy when prescribed by a doctor. If you’re shopping for topical treatment solutions, look for products that contain acne-fighting ingredients such as salicylic acid, benzoyl peroxide, and glycolic acid that can penetrate pores to loosen and dissolve debris. Topical solutions are generally best suited to treat mild to moderate acne. 2. Systematic Treatment: Systemic acne medications are consumed orally, such as antibiotics or hormone pills, and work from the inside out to help clear your complexion. Antibiotics can help kill the bacteria lodged within infected pores to reduce inflammation, redness and swelling. Hormones pills such as birth control are frequently used to regulate androgen levels and treat hormonal acne. You won’t be able to purchase systemic treatments OTC and will need a doctor’s recommendation for these medications. 
The Pore Normalizing Cleanser is designed just to cleanse, not treat, which is a good thing: The Nurse Practitioner study emphasizes the importance of washing with mild cleansers in conjunction with topical acne medications to combat or avoid excessive skin irritation. This one is water-based and fragrance-free, and uses sodium laureth sulfate (as opposed to its harsh cousin sodium lauryl sulfate) to eliminate any chance for irritation.
Acne removal: Your dermatologist may perform a procedure called “drainage and extraction” to remove a large acne cyst. This procedure helps when the cyst does not respond to medicine. It also helps ease the pain and the chance that the cyst will leave a scar. If you absolutely have to get rid of a cyst quickly, your dermatologist may inject the cyst with medicine.
