Red & Blue Light Therapy: A Quick Guide

You’ve no doubt heard of the skincare benefits that come from light therapy, but what exactly is light therapy, and how can it help your skin?

What is Red Light Therapy?

Red light therapy is a form of phototherapy that uses low wavelengths of red light. It is suggested that red light therapy can help improve the appearance of the skin, reducing wrinkles, redness, scars, and even acne, along with other medical conditions. It’s showing great promise in the skincare world, though more research is needed to confirm its effectiveness.

How Does Red Light Therapy Work?

Red light can penetrate into the top layer of the skin and travel to the deep levels of the skin, known as the dermis. This is the area of skin where our collagen, elastin, and other essential proteins reside. It is thought that red light therapy interacts with the mitochondria, which are the powerhouse of the cell. Red light is absorbed by our cells and then converted into energy; with more energy, the cells can work efficiently and promote skin repair and new cell growth.

What Can Red Light Therapy Be Used to Treat?

Research and studies have shown that red light therapy is effective in treating:

  • Stretch Marks
  • Wrinkles, fine lines, age spots
  • Scars
  • Psoriasis, rosacea, eczema
  • Sun damaged skin

More research is underway to confirm that red light therapy can treat these conditions.


Red light therapy has been promoted to have positive potential benefits.

Acne Healing

The gentle red light decreases redness and minimizes the production of oil and bacteria, which ultimately contributes to acne.


Red light therapy increases the production of collagen, along with elastin and hyaluronic acid in the skin, helping it appear more youthful and elastic.

Wound Healing

The therapy improves circulation and brings more oxygen to the skin, which promotes tissue repair and can help diminish scarring.

Other benefits include how safe and non-invasive red light therapy is compared to other skin care treatments.

One of the major benefits of red light therapy is how affordable and convenient it can be. Consumers can use red light therapy wands from the comfort of their own homes and experience its long-term benefits.

What is Blue Light Therapy?

Blue light therapy uses natural violet or blue light to treat conditions on or just under the skin; unlike red light therapy, blue light can only reach the top layer, but it is just as useful.


There are many reasons to incorporate blue light therapy into a skincare routine, as it is thought to provide positive benefits.

  • Blue light therapy is chemical free
  • Treats acne by attacking acnes
  • Anti-inflammation
  • Reduce Oil gland size and minimizes sebum production
  • Diminish acne scar appearance
  • It is non-invasive
  • Does not damage the skin
  • Safe for all skin types and ages
  • Painless

Blue light therapy wands are available to apply at home, and they can be used to treat sun damage, acne, and premalignant skin.

Blue and red light therapy are innovative forms of phototherapy to help treat skin conditions, and portable devices available for them can help you achieve their benefits from anywhere.
