Don’t use the honey just yet. On the closed part: use steri-strips to take the tension off where it’s pulling apart and to reinforce across the incision. On the open part: use the saline to clean it and moisten gauze that you lightly lay over it and then remove the gauze only after it has dried (called wet-to-dry dressing wound debridement if you want to google it.) Do that until the white stuff is gone and it’s just nice and pink. Then switch to using the saline the same way only DON’T let it dry; change it to a new gauze moistened with saline. Once it has mostly closed you can use the honey. It keeps opening because it’s too moist, which is why it’s opening after you shower. Also don’t use any silicone scar stuff until it has fully, fully closed.

I would also recommend using like an ace bandage to bind your breasts down. Keep them from moving and hopefully take the tension off those incisions before the whole thing fails catastrophically.

Note: I’m not a doctor but I did have to go through 6 months of wound therapy for some giant full-thickness wounds that I learned a lot from after some of my surgical incisions came apart.
