great for your skin [SEP] omg these are wonderful i used to rub ice over my face in the morning years ago this is much better it s nice to have to keto cold but i have not had to use more than one at a time they stay cold for with a while when it feels like it isn t cold i roll it a little with my finger and then it s fine this is a fantastic tool to use in the morning especially if you have puffy eyes i like using it before i put on make up at night i will sometimes use it after i put my serums and moisturizer on it s very relaxing
