A month ago I had a CO2 laser treatment on my face, on my both cheeks because of big brown pigments.It healed 10 days, I had no irritation and was using Avene zinc cream.My skin looked so nice after that! Brown spots almost gone.But I have it back now only after two weeks!I am devastated.:((( Has it happened to anyone here?I am thinking about second treatment.How long shall I wait?Thank you.
