Having itchy blister-like bumps after venus viva laser resurfacing. What causes it? Will it scar? (Photo)

Having itchy bumps tht look like whiteheads on my forehead n blister like ones on my cheek after the laser. The forehead ones came the nxt day n the cheeks 2 days after. This is the first time i get those bumps. I had done fractional co2 with no such issues. May i know what causes it? Will it scar? I did not have any bumps before laser. Im using calming cream from doc and Im on antihistamine to ease the itch though. Can I get antibiotics to prevent those blisters like on my cheek?
