Red light, it turns out, may do a lot more than set a sensual mood or help photographs develop properly in a darkroom. According to some researchers, the amber-hued lightwaves may potentially speed the growth of good cells, including the human variety. This claim is further backed by NASA’s use of red light to grow vegetables in outer space and quicken the healing of astronauts' wounds outside of Earth’s atmosphere.

At Red Light Kailua, guests have the chance to put those assertions to the test themselves in state-of-the-art chambers that look and feel very similar to lay-down tanning beds. Inside those state-of-the-art apparatuses, rose-colored light absorbs into the skin—3–4mm into the skin, to be precise—to stimulate the production of white blood cells for quick healing, incite natural collagen production for better looking skin and nails, and kill off bacteria that causes the likes of acne. Other potential benefits of regular visits may include increased circulation, reduced inflammation, and even a reduction in scar tissue.
