Query: Dumbest impulse buy ever

Sudden Change Eye Serum is a rip-off. You might as well stick rubber cement under your eyes for all the good it does. It's like a clear paste that doesn't dry clear. Not only does it do nothing for your under eye issues, it leaves a VISIBLE crusty streak on your skin as it dries. This is an impulse buy fueled by fear of getting older, and you don't need it. Learn from my mistake.
