How long should a product for pimples make you purge? how long is too long? i've been using a bha and aha and one of my cheeks is crystal clear while the other still has bumps. it's been two months. people reccomend to wait three. what should i do?

Toxins, bacteria and excess oil production can cause acne, and are made worse by hormones, environmental factors and diet. Since these factors all vary during a typical month, your acne can flare and recede. Using BHA and AHA can help acne, but may not completely clear it permanently. Eat a healthy diet, drink plenty of water, wash your face daily and avoid oil based makeup/lotions.
