No need to apply any cream by hand. Simply roll them to massage around the eyes. This not only avoids contaminating the product with hand bacteria, but also promotes the absorption of eye cream through physical massage. At the same time, it lifts and tightens the skin around the eyes. The balls fit the contours of the eye area and provide 360° non-stop massage. Rolling from the inner corner to the outer corner can effectively relax the muscles around the eyes, relieve eye fatigue, improve eye circulation, and accelerate the elimination of swelling. The cool metal balls also bring a soothing cooling effect. They are suitable for reducing puffiness in the morning and relaxing eye muscles before bedtime. Making skincare a pleasure, even the lazy can easily stick to it.
