15. Use benzoyl peroxide, salicylic acid and Concentrated vitamin A derivatives
Two ingredients used in many acne treatments are called benzoyl peroxide and salicylic acid. Concentrated vitamin A derivatives are also sometimes used, in addition to sulfur or zinc compounds.
Benzoyl peroxide helps kill bacteria found inside pores, which helps prevent pore clogging. This can reduce infections, redness and inflammation, but sometimes causes negative reactions like dryness, burning and peeling. Always start with a lower concentration to test your reaction, such as a lotion with 2.5 percent benzoyl peroxide.
