Eliminate debilitating knee pain & stiffness at home
Years of wear down, inflammation, and joint strain cause the soft tissues around your knee to tighten, swell, and lose flexibility — resulting in constant pain and limited movement.
Regen™ combines heat, red light, and massage therapy to target all three causes of discomfort. It soothes inflammation, improves circulation, and relieves tension in surrounding muscles, allowing your knees to move freely again without pain or stiffness.
Improve circulation & relax tight muscles with soothing heat + massage
Poor circulation and tense muscles around the knee worsen inflammation and joint strain. Regen™’s heat therapy expands blood vessels to deliver oxygen and nutrients to the joint, while massage therapy releases tension and boosts lymphatic flow.
Together, they reduce swelling, lubricate the joint, and restore mobility, giving your knees the comfort and strength they’ve been missing.
What is relief like with Regen? Better sleep, more energy, comfortable movement, & happier & more peaceful days
Repair cartilage & slow arthritis progression with red light therapy
Regen™’s 660nm red light therapy penetrates deep into the knee to stimulate cellular energy (ATP), accelerating repair of cartilage, ligaments, and connective tissue.
This rejuvenates damaged joint structures, improves shock absorption, and reduces stiffness caused by osteoarthritis — helping you move freely again without grinding, clicking, or pain.
Affordable, safe, & non-invasive solution to treating knee pain for good
