I have a fever blister on chin, started Acyclovir tabs day of, I get those if I am in sun, wind, etc and forget sunscreen?

I had Deka dot fractional CO2 five days ago is it normal to still have some under eye swelling? Just worried because about a year and three months ago a plastic surgeon injected some sort of filler in my tear troughs, I always thought it looked a little puffy/saggy after that. So now I am worried that this is going to exacerbate that? The swelling is getting better, but it has been five days. I also have a fever blister on my chin, treated with Acyclovir the day of treatment and onward, normal?
