Red light therapy seems too good to be true, doesn’t it?
It can take years off your face, it can relieve your pain without medication, and it can greatly help with any skin problem you have – From redness to scars and hyperpigmentation.
But is red light therapy safe? Can it cause any side effects? Long term damage?
The answers are here.
What Is Red Light Therapy?
Red light therapy treatment involves exposing the skin to relatively high intensity light in the red spectrum. The precise wavelength of the light used can range from 600 nm (orange/red) to 850 nm (infra-red).
The majority of the research on this suggests that red light activates processes that lead to a decrease in inflammation, improved healing of skin tissue and collagen production (yay!).
Red light easily penetrates the skin, boosts circulation and brings more blood and nutrients to where ever uou point it.
It also stimulates production of our anti-aging friends – Collagen and elastin. Collagen helps plump the skin, while elastin firms the skin.
Is Red Light Therapy Safe?
Studies so far has found no adverse side effects or risks from using red light therapy, in short or long-term use.
In fact, at the LLLT Symposium, held in 2009, one of the scientists chose to put it like this:
The only way a (low-level) laser is going to hurt somebody is if they drop it on their foot.”
But, if you are pregnant, have skin cancer, or take immune-suppressant drugs – Do not use red light therapy. Also, do not point red light towards your thyroid gland.
Is Red Light Therapy Safe for The Eyes?
According to the FDA, red light at 633nm has a “non-significant risk” status and is completely safe for the eyes. But, to be on the safe side, never look directly at the light source, and use safety goggles when doing a facial treatment with red light therapy.
Red/infrared light itself are not damaging to your eyes, but the best red light home devices can produce high glare, which is best avoided looking directly at.
Can Red Light Therapy Damage Your Skin?
Too much sunlight can affect the skin due to the emission of broad spectrum ultraviolet energy through the atmosphere. Red Light treatment lamps utilize the visible spectra of light at 633nm (red), but contain no UVA or UVB rays.
What’s the Difference Between Red Light Therapy and Laser Treatments?
Red light therapy does not cut, burn or break the skin as with laser treatments. It produces no vaporization or burning of the tissue, and therefore no inflammation or erythema.
Does Red Light Therapy Work for ALL Skin Types?
The Collagen Red Light Therapy is safe and effective for all skin types and colors. The main prerequisite is that skin be clean for effective light transmission.
What About Short-Term Side Effects?
Some users experienced skin redness after treatments. This side effect is usually caused by improper use of red light therapy, especially over-use.
Any side effect can be avoided by following the manufacturer’s instructions and not being tempted to speed up results by over-use.
