Sorry for my very delayed response.

A hydracolloid dressing is similar to a blister patch. I find that they don’t irritate my skin as much as normal bandaids.

What is a hydrocolloid dressing? Where do you get it? My pits just drain continously and I break out from the glue in the tough bandaids.

Mine open and I’d almost rather they stay open because at least they don’t hurt. I hold a swab of apple cider vinegar on the area twice a day to prevent infection and draw out any left over pus. Then I cover it with a hydrocolloid dressing which acts as a second skin. I change it twice a day. I find that if I use a plaster (band aid) it closes and then just fills us again.
