One secret that always works for me is Auquaphor its designed to help irritated or cracked or dry skin! Just dab a bit on leave it over night and it should be soft enough to fall off!! Hope it helps!
Put a hydrocolloidal bandage over it, and leave it there until the scab heals - it should heal over fast. Check out some of the blister bandages that look like jelly stickers - those are hydrocolloids. 3M also makes little acne patches made of hydrocolloids, but they are not marketed in the US.
Oh man, I am so bad about this too. I can't not pop/pick at pimples. I have an all consuming compulsion, I get like nervous bubblies in my tummy if I don't. Apparently that's an anxiety issue. I have scars on my legs because as soon as I see a little mark or blemish I have to mess with it. >_>
Here's what I do for face scabbies. Put a dab of neosporin, or better yet, raw unfiltered honey; then cover it up with a band and and go to sleep. It'll really help clear it up.
