When practical, Neosporin under a Band-Aid over night. It works awesome! and on the face it's great for discontinuing picking that spot. Plus Neosporin reduces scars and if you have existing ones, bio-oil is the best. I know it's oil, but it's gentle enough to use on your face. takes three months to work on existing scars and stretch marks...according to the bottle. But I have no stretch marks from my two kids because I used it.
