I get little red bumps under the adhesive part of certain brand of band aids. The bumps form a pattern roughly equal to the breathing holes in the bandaid, or the non-holes, not sure which, but it is a pattern. The bumps appear usually after about
1 day, and if I don't remove the bandage soon the bumps start to puss up and merge. Some itching. The reaction goes away and gradually heals as soon as the adhesive bandaid is removed.
I don't recall the brand, but it was not Band Aids by Johnson and Johnson. It seems that only the waterproof bandages give this reaction. Also, never had a problem until about
10 years ago, and now I avoid waterproof adhesive strips, and seem to have no problems with J&J or Rite Aid brands. Never did figure out what the cause is, latex or adhesive. Most products don't list the ingredients of the adhesive.
I read an interesting WebMed post about
an investigation that pointed to the adhesive containing Acrylates, causing similar reaction, but seemed to indicate that it was primarily a mechanical effect on the skin, rather than an allergic reaction, although some had a reaction that included allergic reaction plus the mechanical reaction. I didn't really understand what the mechanical reaction means, but it seemed to match my symptoms. The post also stated that the researcher was frustrated with not being able to obtain ingredients for various adhesive "band-aides".
