With the rise of at-home skincare devices, this question is on the minds of many looking to improve their skin’s health and appearance. Join us as we delve into the world of LED light therapy, exploring its purported benefits, scientific evidence, and practical considerations.

From acne to wrinkles and hair loss, LED light therapy has gained traction as a non-invasive and potentially effective treatment. But does it live up to the hype? Let’s find out.


At-home LED light therapy is a non-invasive skincare treatment that uses light-emitting diodes (LEDs) to improve the appearance of the skin. LED light therapy is said to have a number of benefits, including reducing wrinkles, improving skin tone, and clearing acne.There

are a variety of different at-home LED light therapy devices available, each with its own unique set of features. Some devices use a single wavelength of light, while others use a combination of wavelengths. The wavelength of light used will determine the benefits of the treatment.

Types of LED Light Therapy Devices

There are two main types of at-home LED light therapy devices: handheld devices and panel devices. Handheld devices are small and portable, making them easy to use on the go. Panel devices are larger and more powerful, and they can be used to treat larger areas of skin.Handheld

LED light therapy devices are typically used for spot treatments, such as treating wrinkles or acne. Panel LED light therapy devices are typically used for full-face treatments.

Scientific Evidence

Clinical studies have investigated the efficacy of at-home LED light therapy for various conditions. While some studies have shown promising results, others have reported mixed or inconclusive findings. It’s important to note that the quality and design of these studies vary, and more research is needed to establish definitive conclusions.


  • Several studies have found that blue light therapy, specifically at wavelengths around 415nm, can effectively reduce acne lesions. Blue light targets the bacteria that cause acne, Porphyrin, and Propionibacterium acnes (P. acnes), and helps to kill them.
  • One study found that blue light therapy reduced the number of acne lesions by 70% after 12 weeks of treatment.
  • Another study found that a combination of blue and red light therapy was more effective than blue light therapy alone in reducing acne severity.


  • Red light therapy, typically using wavelengths around 633nm, has been shown to stimulate collagen production, which can help to reduce wrinkles.
  • One study found that red light therapy improved skin elasticity and reduced wrinkle depth by 35% after 12 weeks of treatment.
  • Another study found that a combination of red and infrared light therapy was more effective than red light therapy alone in reducing wrinkles.

Hair Loss

  • Low-level laser therapy (LLLT), which uses red or near-infrared light, has been shown to promote hair growth in some individuals.
  • One study found that LLLT increased hair density by 37% after 24 weeks of treatment.
  • Another study found that LLLT was more effective than minoxidil, a common hair loss treatment, in promoting hair growth.

Mechanisms of Action

LED light therapy works by emitting specific wavelengths of light that interact with cells in the skin. These wavelengths penetrate the skin to different depths, where they trigger various biological responses.

The different wavelengths of light have specific effects on the skin:

Red Light (620-750 nm)

  • Increases blood flow and collagen production.
  • Reduces inflammation and pain.
  • Promotes wound healing.

Blue Light (405-495 nm)

  • Kills acne-causing bacteria.
  • Reduces oil production.
  • Improves skin texture.

Green Light (520-560 nm)

  • Reduces hyperpigmentation.
  • Improves skin tone.
  • Promotes lymphatic drainage.

Yellow Light (560-590 nm)

  • Stimulates cell growth and repair.
  • Reduces inflammation.
  • Improves skin elasticity.
