Breakouts & acne
Acne comes from clogged pores, extra oil, bacteria and inflammation. Many cases improve with over-the-counter adapalene or benzoyl peroxide, but moderate or scarring acne deserves a dermatologist visit.
Actives that work
Benzoyl peroxide
strong evidence Typical: 2.5-5%
Kills acne-causing bacteria and reduces inflammation. A large review found about 75% median lesion reduction, with 2.5% and 5% about as effective as stronger strengths.
Adapalene (topical retinoid)
strong evidence Typical: 0.1-0.3%
Normalizes cell turnover so pores clog less. Adapalene 0.3% beat 0.1% and vehicle in a 653-patient, 12-week trial.
Salicylic acid
moderate evidence Typical: 0.5-2%
An oil-soluble acid that clears pores from inside. Guidelines make a conditional recommendation for it.
Azelaic acid
moderate evidence Typical: 10-20%
Reduces bacteria and inflammation and fades marks left by breakouts. Also conditionally recommended in guidelines.
