I was looking for a stable way to get Vit C in my routine, and I think this is a good best. It's easily absorbed into my moisturizer and doesn't take much at all - just a shake or two. No clear results, but Vit C is a long-term product. I liked that I don't have to add yet another product to my line up and get to add this Vit C to my current moisturizing product. Four stars since results are not yet proven.

My skin has had major sensitivity to other vitamin C products I've tried (Skinceuticals CE Ferulic, Drunk Elephant etc), and I had given up on Vitamin C for my skin. However, I have had no sensitivity issues with this powder product. I also like the powder form should have a longer shelf life. I put a little sunscreen on my palm, add a bit of powder, and mix before putting it on my face each morning.

I really love the price point and the fact that it's in a powder form to maintain its stability/ potency. My skin looks great and my wallet is happy

This is a great vitamin c product. It tingles a little and has a brightening fact. The powder is kind of fun to use and hopefully helps the product not degrade.
