The only thing I like about this the cooling metal tear shape applicator. It’s really nice once it touches the skin. It’s metal, thus cooling. Other than that, the serum doesn’t seems to do much for me. I will still wake up with black eyes and puffiness. Granted I always sleep late and wake up early, but I really do want to see a slight improvement. I guess this is more brightening as illuminating is the same meaning? So not a good eye cream for me.
