Acne starts in the pilosebaceous unit when sebum and keratinocytes block a follicle. Bacterial growth (Cutibacterium acnes) and immune response cause inflammation and pimples. Modern treatment includes topical retinoids, benzoyl peroxide, antibiotics (used carefully), hormonal therapies, and isotretinoin for severe cases.
Blackheads (open comedones) form when sebum and shed cells clog a follicle and darken by oxidation. Current first-line treatments are topical retinoids and keratolytic agents; antibiotics are not primary therapy for noninflammatory blackheads.
Acne arises from interacting factors - hormones, sebum, clogged pores and inflammation - and lifestyle can influence flares. Diet (high-glycemic foods and some dairy have been associated in studies), stress, exercise habits, and true food allergies play different roles. Track patterns, simplify skincare, and consult a dermatologist for persistent or severe acne.
Acne arises from clogged pores, sebum, inflammation, hormones, bacteria, and sometimes diet or stress. Start with gentle skin care and OTC benzoyl peroxide or salicylic acid. See a clinician for persistent, severe, or scarring acne; treatments include topical retinoids, oral antibiotics, hormonal therapy, and isotretinoin.
Choose a gentle, non-comedogenic cleanser with acne-fighting ingredients (like salicylic acid or benzoyl peroxide). Cleanse twice daily, avoid harsh scrubs, patch-test new products, and see a dermatologist for persistent or severe acne.

Acne scars form when inflammation from clogged hair follicles damages skin structure. Types include atrophic (ice-pick, boxcar, rolling) and raised scars (hypertrophic, keloid). Early treatment and avoiding picking reduce risk; dermatologic procedures can improve existing scars.
Salicylic acid is a beta hydroxy acid that exfoliates oily pores to treat blackheads and mild acne. Use 0.5-2% products, start slowly, moisturize, and see a dermatologist for inflammatory or scarring acne.
