Why does acne cause pimples?

Each follicle contains a hair and an oil gland. Acne can increase oil production and change the way cells leave the follicle. A plug forms when these materials collect. The immune response to the blocked follicle creates redness, swelling and sometimes pus. Pimples is a very common presentation of Acne, and lesions can range from small raised spots to deeper, tender lumps.

A pimple is not caused by poor cleanliness. Picking can rupture the follicle wall, spread inflammation into nearby tissue and raise the chance of lingering marks or scars.

Cleanse gently and avoid squeezing or scratching. Use products labelled non-comedogenic, and keep pillowcases, phones and hands reasonably clean without obsessing over them. A pharmacist or dermatologist can guide you toward topical options for blocked pores or inflammation. Apply one new active product at a time so irritation is easier to recognize.

Arrange medical advice when pimples are painful, deep, widespread, leaving scars, or continuing despite a careful routine. Seek prompt help for a rapidly spreading red, hot and swollen area, fever, or eye-area swelling, because those features need assessment beyond routine acne care.

Which type of acne lesions do I have? What treatment should I use first, and how should I protect my skin from irritation? What can reduce the risk of marks or scarring?
