    Have you tried any product with this ingredient before? Any visible result?

    nicole: I’ve used Vitamin C many years ago once but I’m not sure what was the ingredient. Now, I’m using TDF C Scape Serum and it’s pretty good but it’s just a derivative of this ingredient. Check my latest post for the details.
