I have been only using Paula's Choice skin-care products for about a year and I love the results! Even though my skin looks and feels great, I still get acne due to my lovely genetics. I use this product as a spot-treatment at night on my acne. It's not too drying, but be careful with using it to often because it has a high percentage (9%) of BHA. Normally, you should regularly apply only 2% or 1% BHA to your entire face. It does slightly sting once applied, but it quickly goes away. This is probably because I have very sensitive skin and also because of the high percentage of BHA.
This product dries up my pimples very fast. Sometimes they even disappear overnight! Give it a try! Paula's Choice has a 100% satisfaction guarantee if ordered from their website.
