Would you describe your skin as sensitive? I have very sensitive skin and my face couldn't take 10% or even 5% so I started with 2.5% and it has been really effective. Enough to keep my acne at bay with only the slightest amount of dryness. I might go up to 5% later on. Maybe you could try a lower percentage if the side effects are bothering you but they are relatively normal for a high percentage of BP.
