In the beginning, bp may cause some irritation and sensitization and just about any moisturizer may sting a bit. You may have better luck if you use our products, but if that isn't possible, try increasing the waiting time between steps and be sure you eased into the bp by just using a tiny amount once daily for the first week. Jumping in with too much too soon can leave the skin feeling quite irritated and sensitive to just about everything.
