Every Mars-Heal product is built around bioceramic stone — a blend of natural minerals set into silicone, fabric, or bead form. These stones are used across the wellness industry for their ability to retain and gently radiate heat (far-infrared warmth) when combined with our corded heating units, or to simply hold gentle warmth in our non-electric pieces like the cervical pillow, knee support, and jewellery. We keep our language honest here: this is comfort and wellness technology, not a medical treatment — see our Disclaimers page for more.
