¿Cómo funciona? ¿Contiene algún fármaco?

No — it doesn’t contain any drugs or chemicals.
It works through WaveWear’s AlignX™ technology, a waved silicone design mapped to the body that recreates up to 80% of the support of kinesiology tape — simply by wearing it.
Reusable, washable, and residue-free.
