Jul 9, 2024

 

How does red light therapy work?

Red light therapy, also known as low-level laser therapy (LLLT) or photobiomodulation, works by exposing the skin to low levels of red or near-infrared light. This light penetrates the skin's surface and is absorbed by cells, where it stimulates cellular energy production (ATP), promotes collagen synthesis, and reduces inflammation. These effects can lead to various benefits for the skin and body.

What are the benefits?

Red light therapy can help reduce wrinkles, fine lines, and acne by promoting collagen production and increasing blood flow to the skin. It may alleviate muscle and joint pain, stiffness, and inflammation, making it beneficial for athletes and individuals with chronic pain conditions. Red light therapy accelerates wound healing by stimulating tissue repair and regeneration. There’s some evidence that it may promote hair growth and prevent hair loss by increasing blood circulation and stimulating follicle activity.

Who would you recommend red light therapy for?

Red light therapy can be beneficial for a wide range of individuals, including those looking to improve skin health, athletes seeking faster recovery from workouts, individuals with chronic pain conditions, and anyone experiencing hair loss or thinning.

Is there anyone who shouldn't try red light therapy?

While red light therapy is generally safe for most people, it may not be suitable for individuals with certain medical conditions, such as epilepsy or thyroid disorders, or those taking photosensitizing medications. Pregnant women should consult with their healthcare provider before undergoing red light therapy.

Are there any risks to know about?

Red light therapy is considered safe when used as directed. However, some individuals may experience mild side effects such as temporary skin redness, irritation, or headache, although these are quite rare. You’ll want to follow the manufacturer's instructions, and consult with a healthcare professional if you have any concerns or underlying medical conditions.

There are versatile red light therapy devices designed for various applications, including skincare, pain management, and wound healing. Look for one that is FDA-cleared for safety and efficacy if you are interested in using at home.  As with any treatment, it is important to consult with a healthcare professional before incorporating red light therapy into your wellness routine.
