Hydrocolloid bandages may be my favorite non-prescription medical supply.  They are basically bandaids* on steroids.  Normal adhesive bandages have some kind of fabric pad stuck to a larger strip of adhesive tape.  Hydrocolloid bandages are a uniform, soft, thick, adhesive polymer and protein matrix, but I don’t really care what they are made of, I care how they work: like magic.
These bandages can be cut to size (even for very small areas, like 1 square centimeter). Â They are latex-free (yes!). Â They keep the wound fully covered, keep edges in place, and keep things moist but not wet – perfect for speeding up healing. Â You can leave them on in the shower. Â If you use larger pieces they maintain pressure, so they are good for areas which might scar (the pressure can help reduce scarring and soften existing scars); they’re not as good for this as scar treatment bandages, but they do in a pinch. Â I use them for cuts, scrapes, small wounds, and acne lesions, but they are also good at keeping nasogastric tubes (and presumably other tubes) in place without irritating the skin like a lot of medical tapes do, and they are used to treat bedsores. Â Don’t use them for very serious, deep wounds, or burns, or anything you wouldn’t use a regular bandaid on.
Most bandage/first-aid brands, including store brands, carry hydrocolloid bandages, in stores they are always in the bandaid section (and are sometimes sold as blister bandages). Â I always have some on hand.
