Red Light Therapy and Skin Health.

Taking care of your skin has been a vital part of your overall health for many years, so why do we do it? We’ve been told to take care of ourselves and stay clean, but why? Skin plays a huge role in your body’s overall health. From temperature and hormone regulation to protection from outsides sources such as fluctuating weather and bacteria. Red Light Therapy uses high-quality devices to enhance your cellular function throughout your body. In turn, this provides support to healthier and more vibrant skin. In this article, we explain why your skin is so important, and how red light therapy can provide positive effects on the skin.

The Importance of Skin

Skin, even at its thickest point is only a few millimeters thick. It is still our largest organ, making up over one-seventh of our body weight. This just goes to show how important your skin is. So what does skin even do? The skin has a ton of different functions. It’s an outer layer that acts as a thin barrier, protecting your body from harmful things such as the cold, heat, germs, and toxic substances.

Just looking at someone’s skin can tell you a lot. For example, you can get a general sense of their age and health. Changes in skin color can also be a sign of a medical condition. People with too few red blood cells could look pale, as an example. Below are a few of the important functions that the skin provides.

  1. Protection: The skin is a barrier between us and the dangers of the outside world. It protects us from all of the invisible invaders that we can’t see. Skin is an essential part of a healthy immune system and is one of the first forces to protect you from toxins, allergens, and microbes at the surface of the skin.
  2. Circulation and repair: Skin is one of the most important supporters of a healthy circulatory system. Good blood flow means proper nutrient and oxygen circulation. Blood flow brings nutrients to the skin and removes waste products. When the skin gets injured or damaged, circulating blood delivers proper nutrients and oxygen for proper repair.
  3. Storage: The deepest layers of our skin provide essential storerooms for fat, water, and metabolic products. This is important for an efficient nutrient distribution. Our skin also provides Vitamin D, which is made when the skin is exposed to sunlight.
  4. Temperature regulation: The skin is your first defense when regulating your body temperature. Your skin protects you from the heat and the cold and helps prevent dehydration.
  5. Beauty: Skin is a very important feature when it comes to our self-perception. Every day we look in the mirror to see what we look like, sometimes this can affect our self-esteem and mental health.

What is Red Light Therapy?

Red Light Therapy, also known as Photobiomodulation (PBM) or Low-level laser therapy is the use of near-infrared and red light to stimulate healing, relieve pain, and reduce inflammation. Secondary effects include increases in ATP production. These effects produce factors that lead to improved cellular survival and migration. The term red light therapy refers to treatments stemming from LEDs that deliver specific wavelengths of Red and NIR light.

Red Light therapy works by enhancing cellular function and providing an optimal environment for cellular proliferation and migration, and also new protein synthesis. This means your cells are enhanced and are able to work properly. This can lead to reduced inflammatory markers and an overall reduction in inflammation, which plays a large part in joint pain, traumatic injuries and lung disorders.

So what is Red Light Therapy? Red light therapy is the use of devices with LEDs that provide a certain wavelength of light. This wavelength is the perfect level to provide cellular enhancement. This cellular change can cause many different types of benefits such as inflammation reduction, skin repair, and much more.

Skin health and Red Light Therapy

Inflammation is one of the top causes for pain in the human body. It can wreak havoc on spaces that need to move, and can cause even more problems with your skin health and appearance. In addition to supporting cellular function and migration, red light therapy also provides anti-inflammatory effects.

When certain dendritic cells were isolated and subsequently activated using toll-like receptors, they showed the un-regulation of cell-surface markers, which provided a reduction to all markers of activation.

  1. Inflammation and RLT: Photobiomodulation (PBM) therapy reduces levels of pro-inflammatory cytokines in activated inflammatory cells. These markers are active in murine DCs in vitro. Many studies have been conducted, and we recommend taking a look at specific protein chains here.

Why use RLT for Skin Health?

Ten years ago you would only hear, or even see red light therapy units in high-end spas and salons for skin treatment. Thanks to progress in technology and the affordability of production, the awareness of RLT has skyrocketed. Red Light therapy is accessible to everyone. Many of the world’s leading experts trust red light therapy as an addition to their routine, and support the studies revolving around RLT.

Skin is the largest organ, and it covers every part of your body. When you think of skincare you think of your face. Yet it’s a lot bigger than that. Your face is not the only place that needs tender love and care. Balance is an important factor in life and it’s important to understand your body works as one, full-body RLT provides a full-body effect that can improve your overall skin health.


Skin health is one of the most important and essential things for your overall health. Skin is important for blood and nutrient circulation, temperature regulation, and protection from microbes. It’s important for your physical and mental health, and it’s vital to take care of more than just your face, but getting a balanced treatment combined with a healthy lifestyle is the key to overall success. Red Light therapy can help support overall skin health, provide inflammation relief, and support proper cellular proliferation and migration.
