Causes

sebum. When the outer layers of skin shed (a natural and continuous process, normally), dead skin and oily sebum left behind may bond together and form a blockage of the sebaceous gland at the base of the skin. This is most common when the skin becomes thicker at puberty.[2] The sebaceous gland continues to produce sebum, which builds up behind the blockage, allowing bacteria to grow in the area, including the species Staphylococcus aureus and Cutibacterium acnes, which causes inflammation and infection. Other causes of pimples include family history, stress, fluctuations in hormone levels, hair and skincare products, medication side effects, and un-diagnosed or underlying medical conditions.[3] Pimples can be part of the presentation of rosacea.[4]

The American Academy of Dermatology recommends that adults with acne use products labeled as "non-comedogenic", "non-acnegenic", "oil-free" or "won’t clog pores", as they are "least likely" to cause skin irritation or acne.[3]

Over-the-counter medications

Common over-the-counter medications for pimples are benzoyl peroxide, salicylic acid, adapalene, and antibacterial agents such as triclosan. These topical medications, which can be found in many creams and gels used to treat acne (acne vulgaris), induce skin to slough off more easily, helping to remove bacteria faster. Before application, the face should be washed with warm water or a topical cleanser and then dried.

A regimen of keeping the affected skin area clean, plus the regular application of these topical medications is usually enough to keep acne under control, if not at bay altogether. The most common product is a topical treatment of benzoyl peroxide, which has minimal risk apart from minor skin irritation that may present similar as a mild allergy.[6] Recently, nicotinamide (vitamin B3), applied topically, has been shown to be more effective in treatment of pimples than antibiotics such as clindamycin.[7] Nicotinamide is not an antibiotic and has no side effects typically associated with antibiotics. It has the added advantage of reducing skin hyperpigmentation which results in pimple scars.[8]

Prescription medication

Severe acne usually indicates the necessity of prescription medication to treat the pimples. Prescription medications used to treat acne and pimples include

alpha hydroxy acid, azelaic acid, and keratolytic soaps.[9]

Historically,

tetracyclines and erythromycin were prescribed. While they were more effective than topical applications of benzoyl peroxide, the bacteria eventually grew resistant to the antibiotics and the treatments became less and less effective. Also, antibiotics had more side effects than topical applications, such as stomach cramps and severe discoloration of teeth. Common antibiotics prescribed as of 2001 by dermatologists included doxycycline and minocycline.[10]

estheticians in favour of allowing pimples to run through their natural lifespans.[16][17][18][19][20] Some dermatologists offer incision and drainage services to sterilely drain the pimple.[21]
