Burn around nipple after laser hair removal, will it heal on its own or should I see a specialist?

i had laser hair removal around nipple area and when i got home i saw that skin got grayish-brown is some places. The largest burn is about 1 cm in diameter, and there are also two smaller ones. There was no blister and no pain. I am currently applying dexpantenolum on the area.I am worried that this may be 3 degree burn. Is the skin gonna heal on itself or do i need to see a specialist?
