How does this mask compare to other vitamin c products? Is it possible to leave it on instead of washing it off?

I wouldn't leave it on instead of washing it off. I forgot to rinse it within the 15 minutes the directions recommend and it just left a sort of sticky residue on my face. As far as how it compares to other products with vitamin C I'm not real sure because this is the first vitamin C facial product I have used but this mask is amazing!
