Bests & Worsts Reviews from Amazon

I bought this product because I was searching for a Vit C powder without GMO. My Dermatologist suggested I make a Vit. C serum for damage skin on my face & chest. I've had very good results. I returned to my Dr. after using it only 2 1/2 months & she saw remarkable changes/healing. She wanted me to up it a little for my nose but the rest of my face & my chest had dramatic healthy skin changes. I did not expect to find these changes at my age. I highly recommend this if you want to make a Vit. C serum for rejuvenating your skin & heal or prevent aging skin issues.
