I have the same thing, like 15-20 small red bumps on my chin that occassionally turn into whiteheads. I have a few posts about it. Ive tried the Pan Oxyl and it helps to an extent but doesnt clear the bumps for me. My entire face is smooth and nice with the exception of my chin. And I'm already using a lot including topical/oral atibiotics, retin-a AND bp. And hp, triclosan, vitamin A, and ACV. And the bumps remain.. Its very embarassing, i know. Of all im using, i think the bp has helped the most, but not cleared me.
My doc says its just acne, deep acne.. : ( Accutane's probably the only thing that'll make mine completely go away. DOnt squeeze em.. I exfoliate the area, and that helps.
My best advice is be gentle to these bumps, or you'll end up with more bumps and really bad scarring... Ive had these for about 5 years now.
I know there so annoying , Unfortuantely BP doesnt agree with my skin whatsoever , so Im using a neutrogena Cleanser atm It helps the rest of my skin exept my chin , Also It doesnt dry them Up either so they just stay there for ages and they only go if I get the white stuff out

Thanks anyway
