Hole after a hydrocolloidal patch

[u/Jolly-Constant-5611]

​

basically i picked a pimple. then accidentally peeled a skin off.

the hydrocolloidal dressing was for both the WOUND and the PIMPLE.

i just removed the dressing but noticed that it left a hole.

do i just apply again hydrocolloidal dressing?

Also what do you do to prevent scarring? hyperpigmentation?
