I purchased some oxy pads, 2%. After about 3 days I noticed a little clearing but I also noticed a few more whiteheads pop up. Is this normal? Is this part of the "cleansing" process? I've made an apointment to ses a dermatologist, but can't see him for a few weeks. When using a medication like this how long before I should expect to see results? I know it doesn't happen over night, but any insight would be helpful.
