I Had IPL and There is a Blister on my Chin, Will this Scar?

It's been four days. Technician said it would go away within five days. Not a chance. Blistered area seems to be getting smaller, but am concerned it appeared in the first place. It's about the size of a pea. Sort of looks like a bad blemish. I've been putting neosporine cream on it and trying to get it to peel away. Is there anything else I should do to ensure no scarring and that it heals properly?
