Can red light therapy increase vitamin D levels, and how does it differ from UV light for skin health? Can it be a substitute for sunlight in producing vitamin D?

Red light therapy and ultraviolet light have different roles in the skin. Red light therapy works in the deeper layers of the skin, inducing collagen, which is essential in wound healing and lowering inflammation without inflicting harm, therefore, it is safer.

Excessive UV light exposure, on the other hand, serves the function of vitamin D synthesis. However, with more than enough exposure, people may have lighter skin, get wrinkled quickly, and even develop skin cancers. But red light therapy is contrary to these risks and is thus more suitable for skin rejuvenation.

That still does not help in elevating the levels of Vitamin D, as there is no ultraviolet B radiation, which the body requires for Vitamin D synthesis. This shows that those who want to take care of their skin while taking vitamin D will have to opt for a combination of light therapy and moderate exposure to the sun.

Red light therapy uses wavelengths outside the UV spectrum, so it does not stimulate vitamin D production or replace natural sunlight. However, red light may benefit skin health by increasing circulation and collagen production. At my company, we've found red light therapy helps reduce signs of aging like fine lines and age spots. For vitamin D, limited sun exposure or supplements are still needed.

While red light lacks UV, it is a safe option for those avoiding sun exposure. For some clients, combining red light therapy and UVB sun or supplements has provided the most benefits. But individuals should always consult their doctor before starting any light therapy regimen.

No, red light therapy does not increase vitamin D levels. Vitamin D production is triggered by UVB rays from the sun, not the red or infrared wavelengths used in red light therapy. Red light therapy has many benefits, including improving skin health and reducing inflammation, but it doesn't play a role in synthesizing vitamin D.

Red light therapy and UV light are different in their effects on the skin. Red light therapy is used for its healing properties, like skin rejuvenation and reducing inflammation. While UV light (particularly UVB) is what helps to stimulate vitamin D production but can also cause skin damage, like a sunburn or an increased risk of skin cancer if its not used cautiously.
