The truth is, being gentle is a major key to clear skin. The goal is to balance the skin to produce just enough oil, and keep bacteria off of your face.
Most times when people struggle with acne they are too harsh with their skin. So many times we are taught to think more equals better, and naturally it is easy to think that more scrubbing, more topical treatments and more washing will make the acne go away faster.
Clearing away bacteria gently from pores is the first step, the second is to find ways to balance the skin from the inside and out. Try to treat your skin like you did before you had acne, but remember to keep it clean.
