CO2 Laser skin tag removal complications on neck? Early sign of hypertrophic scarring? (Photo)

I had several benign skin tags/moles removed from my face, and a small cluster on my neck. I noticed that the ones on my face are healing, but the small cluster on my neck look rather irritated. The borders of where the skin tags used to be are red. Almost like a red ring. The center appears to be white. The red rings are not flush with the skin when you feel the area. It's been about 4 days post OP. Very worried these are early signs of hypertrophic scars. Chances of CO2 causing this? :(
