@donasmrs-- After your comment, I went and checked the eye cream box for ingredients. It doesn't list the percentage of vitamin K. I actually couldn't locate vitamin K in the ingredients list at all! No wonder it doesn't work! I also checked reviews and it has awful reviews.
I'm going to buy another eye cream with vitamin K, but this time, I'm going to do lots of research. I'm reading reviews of creams right now and I'll even call manufacturers to find out the percentage of vitamin K if I have to. Thanks so much for your comment! I'm definitely wiser now.
