After applying an eye serum or eye cream, gently slide the tool on the under eye area, starting from the inner corner of the eye to the temple. Repeat a few times and follow by gently gliding the tool above the eyelid to reduce puffiness. Due to natural variations in stone, every eye tool is unique in color and pattern. The stones + crystals we use are authentic and natural. We do not artificially dye or treat the stones to let their true beauty shine through.
