"What you percieve as reduced healing time may be because, 1) Alcohol is a drying agent and the scab just seems dry and healing. 2) Peroxide, dissolves blood and some of the clot so you may see a dissappearance of the scab sooner but immature skin is underneath. 3) Neosporin, especially if used with an occlusive dressing keeps everything kind of greasy and wet." . . . .
