Will Putting Polysporin on a Chest Blister Prevent Keloids or Create Them by Overhealing?

Our treatments use combination therapy to improve the epidermis and dermis for most deep scars. The options available for acne scars depend on the character of your scars, in terms of topography and contour. We see atrophic and hypertrophic acne scars, as well as scars that have hypo and hyperpigmentation. We begin each scar evaluation with an assessment of scar quality and subtype. Our main concern is rebuilding collagen and that is why we use a HIDEF protocol that includes combination therapy. Morpheus 8, scar subcision, fibrous release, fractional laser, CO2 laser, Thulium laser, PDL Vbeam laser, and fractional resurfacing can be used in addition to TCA Cross and chemical peels to further improve skin. Patients should start Melarase AM and Melarase PM for active hyperpigmentation. Always begin with a consultation to decide whether early subcision should be started.

Usually blisters form if there is damage to the junction between the top two layers of the skin.  If the damage goes below this junction, there is a possibility of a keloid.

Polysporin, if you are not allergic to it, will coat the wound and help it heal more rapidly.  The sooner the wound heals the better its appearance.  If the blister is just at the junction, the skin should heal without a keloid.
