Match the treatment to the breakout
Acne is not one condition. Blackheads and whiteheads are clogged pores. Red, painful papules and pustules are inflammatory. Deep, tender cysts sit far below the surface and can scar. Treating all three the same way is why so many routines stall, and why people conclude nothing works when the problem is simply the wrong active ingredient.
Broadly: salicylic acid clears clogged pores, benzoyl peroxide targets the bacteria driving inflammation, and retinoids keep pores from blocking in the first place. Persistent cystic acne genuinely needs a dermatologist rather than another product. Stripping your skin with harsh cleansers backfires by damaging the barrier and provoking more oil. The reviews below flag which type of acne each product is actually formulated for.
