When is it best to use Vitamin C serum?
Well, she’s sort of half right on this but here’s why you should still use in the morning. When you put in on it binds to your skin cells. When the UV rays hit the cells and create free radicals, the Vitamin C protects the DNA of your skin cells from damage by scavenging those radicals. So….. in a sense it is breaking down but you want it to!!!! That’s the way it protects the DNA of your skin cells. I recommend using it under your sunscreen and using your Vit A cousin creams at night. Dr. I
