Blister or tape has ripped off skin after BA/BL/BR. What treatment should I do? (Photo)

I am 7wekks post op. I am still fully taped. 52yrs old. Watching TV tonight I felt an ouch. Touched my left boob and thought oh that's wet.... had a look and thought my tape has come off and taken skin or I have had something rubbing on it today and it was a blister that popped. Not quite sure what sort of creams, dressings I should use. Any ideas? I hope someone reads this. Thanks.
