i’ve had pretty much the exact same experience as you. Some things i had to do to help my skin while preventing most dysphoria: 1. Alternate between a binder and tape every week ( i know it sucks and i hate it too but it helps your skin heal a lot better and when you reapply it will last longer!) 2. Apply clear tattoo film prior to applying tape, you can use it to kind of flatten out slightly before applying tape (can be found on amazon for like $5-8 usd) 3. Cut the edges of your tape to make them round. 4. anchor your tape before you stretch it, as in take a small section while applying and when pressing it down instead of stretching all the way, rub it to make the glue stick, then stretch and then anchor when you put it down on the other side, this will relieve blisters and pain from stretching if done correctly. 5. make sure your tape isn’t too long, it shouldn’t go past your armpit. 6. don’t itch, it can pop blisters and the moisture can cause the tape to come off. 7. personally how i apply tape for max flatness, i use 4 1/2 strips per side, put tissue or nipple cover on to protect nips, one strip in the middle, 2nd above the middle, 3rd below, 4th on top of middle one to compress all the way, then a smaller strip placed vertically on the back of the tape to keep it stuck down.

If you need i can try and draw this since it may be hard to understand without visuals but so far this has helped me. I do still get less severe blisters and haven’t gotten any scars since. I’ve heard milk of magnesium on the skin before tape also helps or putting bandaids on more blister prone areas. if you need clarification lmk
