This eye roller does feel refreshing and cool to the under eye area. I like its non-greasy, light and oil-free formula. In terms of reducing puffiness underneath the eye, I can't tell because I never had puffy eyes. But I have always used under eye treatment, be it this brand or another. May be these eye treatments are indeed effective in preventing puffiness under the eye. I can only say that the skin condition underneath my eye area has remained the same, no better and no worse. I guess when it's not getting worse, that means this eye roller is working? Overall I like this product. ( 0.5 fl oz at $12.99 ).
