1. Blackheads form when pores become clogged with dead skin cells and excess oil. Gentle exfoliation and products containing salicylic acid or retinoids can help unclog pores and prevent future blackheads by increasing cell turnover.
2. Long-term strategies for preventing blackheads include choosing oil-free products, avoiding blocking pores, managing stress, and watching dairy and high-glycemic food intake as these can increase oil production.
3. In-office procedures like chemical peels, microdermabrasion, or extractions can provide faster results for treating existing blackheads but require at-home skin care afterwards for maintenance.
