First time try Hydrogel mask, it is cool and moisture, I would highly recommend this product to my friends. And to the LED mask, I believe it will give me skin positive effect since theoretically it should works. Then time will tell everything, I will keep using it. Sleeping mask is just fine, I give it to my BF, Actually, I regard it as the gift from CurrentBody, thus not expect it could have surprise for me. And in fact it is just a comfortable fabric sleeping mask, no more function. 😄Overall, this is a pleased shopping experience.
