How to heal a burn caused from microdermabrasion?

I have been using an at home personal microdermabrasion kit for my acne scars (my skin tone is slightly darker than a caramel color), which has helped drastically fade them. However, I graduated from the sensitive heads to the more aggressive ones and apparently burned the skin around my laugh lines. It's been about 3 1/2 weeks and I've seen some healing, but is there anyway to speed up this process. I'm not sure what to do. It's embarrassing and its hard to cover with makeup.
