These two products were used as my last resort as I planned on going on Acutane if it didn't treat my acne (due to trying so many products and nothing working). However, this has been amazing, to the point where my acne has now disappeared. It removed the itchiness, the sebum and the infected spots that I had on my forehead. This took around 3 months. I also used this in combination with the COSRX salicylic acid cleanser. PLEASE GIVES THIS A GO IF YOU'RE SUFFERING FROM ACNE, IT WILL DO WONDERS TO YOUR SKIN!
