I mix it with my other serums for extra vitamin C benefits.

I like the powder - I notice my skin is much brighter. Will repurchase.

Warning: I had big problem when used on my neck. Very raw, sore and bumpy skin. Didn't have the same problem with my face, and I am not even sensitive skin type. So be careful!

I noticed no difference to my skins brightness, this product caused my skin to get red burns maybe? Like patches of sore red skin. Very irritated. Very drying even on my super oily skin also smells gross if you don't wash hands straight away. Smells like meat. Also leaves an orange tinge on my fingers! Thought it was rust! Very sad as heard such good things!

Excellent product for it's pice and it does work as well.
