If you have 
acne-prone 
skin, your first line of defense against breakouts should be a daily skincare regimen that decongests pores, exfoliates skin, and helps prevent future breakouts. Facial masks work to supplement your daily skincare regimen by delivering additional key ingredients to exfoliate, detoxify, and balance the skin.
When searching for a facial mask for acne-prone skin, it is especially important to look for ingredients that exfoliate dead skin cells to help prevent clogged pores from occurring. This includes formulas containing hydroxy acids such as lactic, citric, or 
glycolic acid. Facial masks formulated with natural earth clays such as kaolin and bentonite are also recommended, as they absorb excess oil and help decongest pores.
