Red light therapy: What you should know

Red light therapy: What you should know

Red light treatment (RLT) is a therapy that can help rebuild the skin, muscle tissue, and other areas of the body. It exposes you to low red or near-infrared light levels. Infrared light is a form of energy that can not be seen by your eyes, but can be felt as heat by your body. Red light is infrared-like, so you can see it.

Anyone who is unsure whether RLT is right for them or not should speak to their doctor.

How Does it Work?

To fight signs of aging, Red Light Therapy is a 100 percent safe, chemical-free and drug-free medium. The natural red light used in the LED lamp penetrates into the skin to cause cellular activity, unlike chemical solutions or toners that you add to your skin. You don’t have to let your skin see through all those chemicals that can be toxic to you in the long run.

It is a treatment that is painless, non-ablative and non-invasive. To correct signs of skin aging, all you need is to bask under the light and let it help develop fibroblasts and collagen. No need to go under the knife or use needles to torment yourself. It does not cause skin damage and needs zero downtime. Without having to worry that your skin will look bad, all you need is 5 minutes and you can go about your day, apply makeup, go to work or go out with your friends.

The mitochondria in the skin cells can absorb these light particles, as a report in the journal Seminars in Cutaneous Medicine and Surgery reports. This will help to generate more adenosine triphosphate from the cells, which is the source of energy for all cells.

For all skin types, this light therapy is effective and has no reported adverse side effects. To treat full facial wrinkles, this well-researched at-home red light therapy system is FDA-approved. For all ages, it is safe. In operating the system, individuals with a restricted range of motion or physical disability and the elderly may need support.

What Does It Treat?

For a while, researchers have known about red light therapy. They don’t know if it’s better than other forms of medication used to help you recover, but there aren’t a lot of research on it. Red light therapy could assist with:

  • Acne and Inflamed Acne Marks: While Red Light is not used to destroy bacteria that cause acne, it can help to decrease the inflammation caused by acne. At various stages, Red and Infrared lights penetrate the skin and power up the cells to rebuild the skin from inside. This replaces the tissues of the skin that acne has ruined. This leads to quicker acne healing and prevents more damage to the tissue that can lead to acne scars. In the other hand, it is scientifically proven that Blue Light Treatment starves from P. acnes bacteria, which is the most common cause of acne.
  • Bites: Because of the ability of red light to speed up healing, bite wounds or skin punctures can heal more rapidly due to increased blood flow to the region.
  • Bruises: Bruises are caused by either direct damage or damaged capillaries by leaking blood into the skin tissues. And without any break to the skin, the blood will not go out of the body, it gives off a bluish hue that is what we sometimes call a bruise. Red light therapy will be able to supply the region with nutrient-rich blood quicker, which will restore and help in the creation of new capillaries.
  • Minor Burns: Red Light Therapy does not emit heat, so it does not contribute to the damage caused by the burns. What it will do is improve the blood flow to the region so that the normal defenses and repair mechanism of our body will be able to do its job more quickly.
  • Cuts, Scrapes and Treatment for Wounds: Increased blood flow to the region, as described, helps speed up the ability of the body to naturally repair itself.
  • The Red Light penetrates the thickened skin and energizes the skin cells. Dry Skin and Psoriasis: More nutrients are distributed to the region because of the increased blood flow to the surface of the skin being treated. That means it quenches the skin’s thirst to be nurtured. Blood flows rich in oxygen to the treated areas, even increasing the hydration induced by good blood supply.
  • Scars and Stretch marks: Stretch marks are caused by either weight loss or ageing due to saggy skin. The loss of collagen from the body results in loose, stretchy and saggy skin. Red light therapy helps to promote the development of collagen, thereby stopping stretch marks from forming further. It also tends to lighten and lessen scars and also the overall color of the skin.
  • Sun Damage: Red light is a superstar in sun damage correction. UV-free LED bulbs are used to provide red light therapy safely and efficiently. To help reverse sun damage, the red light wavelength spurs cellular activity. It can lighten spots with age.
  • Wrinkles: The wrinkles begin to creep up on our face due to collagen loss (or neck). To help correct these unsightly tell-tale signs of aging, red light therapy helps improve the development of collagen and fibroblasts.

Side effects

RLT is a mechanism that is totally normal. It exposes the skin to light levels that, unlike UV light coming from the sun, are not harmful.

There is practically no chance of side effects from undergoing RLT due to this. However, tissue and cell damage can be caused by a doctor with little experience or someone who exposes themselves to too much of the procedure.

Home-use products can also result in misuse, harm to the skin, burns, or damage to exposed eyes.


In general, RLT is safe and can be a very useful treatment choice for people who are looking for smaller skin changes or for keeping the skin healthy and reducing inflammation.

Other RLT applications have promising early evidence, but in every case, there is insufficient reliable evidence in humans to call it successful.

RLT is only one component of a full routine of skin care, and it should not be the only way a person takes care of their skin. For a person to begin noticing the changes in their skin, it may take many RLT treatments.

To explore the possible benefits, anyone unsure if the practice is right for them should speak to a doctor.
