Just have a anti-acne regimen and be consistent with it. IDK how your skin looks like or if it's severe. I am going to assume it's a recent breakout. Maybe you can use a 10% Benzoyl Peroxide cleanser, a anti bacterial gel that contains Tea Tree Oil or Salicylic Acid in the AM with a non-comedogenic SPF lotion. At night, use the same cleanser and apply a gel or lotion that has salicylic acid or benzoyl peroxide. If your skin is tough, add a sulfur based mask. And spot treat pimples with 2% Salicylic Acid spot treatment from Neutrogena or Clinique;I tried both of their spot treatments and they do work fast to reduce or nearly eliminate the pimple the next day. The clinique spot treatment itches/burns a little though. Or spot treat with organic 100& tea tree oil, that works too. You can also try to eat SUPER clean for a few days, more focus on veggies, fruits and less processed foods to get various nutrients in you. Or even exercise to get rid of some toxins.
