I have very sensitive skin and was told this would be perfect for my skin. So I tried the NutriminC RE9 I gave it about 2 months and it was awful. I scratched my face till it would bleed. Within a week of stopping the product my skin was back to normal. I consulted my dermatologist who said I had an allergic reaction to it. When I bought the product I was told it was hypoallergenic and that I would have now problems.
