Enlarged pores and blackheads are very common and entirely harmless. They happen when excess oil and dead skin cells clog your pores. To treat them, look for creams or serums containing these generic active ingredients: 1. Salicylic Acid (BHA): Penetrates deep into pores to clear out oil and debris. 2. Topical Retinoids (such as Adapalene or Tretinoin): Boosts skin cell turnover, preventing clogs and smoothing skin texture. 3. Niacinamide: Helps regulate oil production. Start these treatments slowly (2-3 times a week) to prevent irritation, and always apply sunscreen daily, as retinoids increase sun sensitivity. A dermatologist can provide a tailored plan if you need further guidance.
