I'm orange...
When I first started using this I was like, “great, a vitamin C that doesn’t burn”. So I began using it frequently. Slowly, I noticed my skin was turning orange, but just on my face. Turns out this product was oxidizing ON MY SKIN. The serum itself was still pretty clear, so I wasn’t applying an old or bad product, but when exposed to oxygen while on my face it began to STAIN it as if I had applied self tanner only to my face.
Now to be fair— I am fair. As in I am very very pale. Honestly even if this product was oxidizing on other people I don’t think the majority of skin tones would even notice it. But if you are like me just be warned! Vitamin C can stain your skin and it’ll take like a week for the effects to go away.
Let’s just say I’ve given up on finding a vitamin C serum and I’ll be sticking to other brightening ingredients.
