Yes, place a hot towel/ washcloth on the left over scar. You will not get it to go all the way down, but it will help alot. Another thing is when you feel the pimple coming place ice on it to reduce the swelling. Also after you pop one, and try to do this only at night, place neosporen on the remaining red, with a small bandaid, in the morning there will be a scar but not as bad as normal. I always do this and my scars seem to get better faster.
I have two suggestions and it depends on the zit which will work best. First, the neosporin on a zit. after you pop, neosporin can get in the skin to help prevent infection, which helps prevent scarring and the skin being red, inflamed more than necessary. If you pop, but think the zit could still have more in there or need drying out., like if you pop and then there's pus still in there... don't try to squeeze pus out of a zit. it will just make the skin irritated. use something to dry out the zit, but not too harsh. i read in glamour-type magazine a while back that J.Lo makes an asprin and water paste and applies to zit at night to dry it out. i'm dying to knw if it works. i haven't had that type of zit lately to try it out on. i've unfortunately had the type zits that I mess with and then they look like open sores. uuugggh! good luck.
