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.
