Color Changing Wand?

I lookup the data on Picky, this wand has vit C derivative in it, it’s actually pretty stable ingredient. Most of the times products with vit C tends to change to darker color as it oxidizes. If you’ve been using it for some time, it could be oxidized hence the color change. Yellow color is still safe to use, I wouldn’t use it if it’s orange or darker.

yellow is ok,but if this will be dark yellow cant use because its with Vitamin C

😍😍

Interesting product! Does it actually work for the dark spots?

Mine has always been light yellow-ish!
