GeneXC vs. ProHeal
This is a strong, excellent serum. The trick is to know when and how to use it. It took quite a bit of research to figure this out. I like the beautiful simplicity of iS, and was stumped until. I found an iS comment on a customer review about this. GeneXC is preventative. ProHeal is treatment for after the fact. That simple! I have been using GeneXC while waiting for my new ProHeal order. It works. Don't forget SPF! Love iS!
