I do kryogenics and before I go in now I use these cups. They bring your cellulite to the surface and by doing so you lose weight faster, or I do. I feel like they are working better for me than taking something internally. They are easy to use, the smaller one around the face and the larger one for stomach and thighs. The bag is convenient to carry them in and easy to locate in my gym bag. They are durable and long lasting. Plyable plastic cups.
