HALOTHERAPY

In certain studies, red light therapy has been shown to help reduce inflammation by decreasing levels of inflammation-causing molecules called pro-inflammatory cytokines. 

Light-based and laser therapies are often used to treat acne because the light can penetrate deep within the skin. 

Red light targets your sebaceous glands — small ducts that release a pore-clogging, acne-causing oil called sebum. The effect of the light helps reduce inflammation within those sebaceous glands, which may improve the appearance of acne.

Your skin is primarily made of collagen, a protein that prevents it from sagging and keeps it looking and feeling plump. While the body naturally produces collagen, sun exposure, smoking, pollution exposure, and aging decrease production, causing skin to lose elasticity and appear to sag and wrinkle.

A 2014 study found that full-body exposure to red light over the course of 30 twice-a-week sessions increased collagen density on participants' faces and caused visible improvements in wrinkles and skin roughness. 

Red light therapy could help reduce pain from a couple of types of arthritis. Recent human studies are limited. One small study from 1992 found that red light therapy led to a more than 50% reduction in arthritis pain in patients with degenerative osteoarthritis in both knees.

Red light therapy boosts metabolism. When the body is starved of oxygen and nutrients, it increases metabolism to compensate for the deficit. Since red light therapy improves circulation, it also activates the body’s metabolic system. It improves oxygen delivery to the muscles and thus stimulates muscle movement.
