Today, it appears that people are ready to go to any lengths to get glowing skin and a beautiful face. From gua shua massages to wrinkle patches, there are countless fascinating ways to solve every skin and wellness issue.

Apart from conventional serums and moisturizers, one of the latest trends in skincare is red light therapy. Besides red light, there is blue, yellow, green, and near-infrared light therapy. Out of all, red light with longer wavelengths is capable of going deep into the skin and triggering collagen and elastin production, which are vital proteins for skin health. 

Red light therapy can be used in the form of portable wands, lamps, masks, and so on, and it is a new favorite ritual among dermatologists and celebrities. Popular in professional estheticians' offices for years, red light therapy devices are now available for home use. JOVS beauty technologies, for instance, 4D red laser masks, offer a world of possibilities.


What Is Red Light Therapy?

Red light therapy (RLT) is a form of photomedicine that involves exposure to red light, which can help improve skin quality and reduce inflammation. It is a non-invasive treatment performed with low-intensity red light to effectively eliminate fine lines, scars, redness, and acne. It is also believed to have the ability to cure other diseases. However, more needs to be done to assess the validity of the treatment.

Interestingly, red light therapy has 60 other names; a few are listed here. 

  • Low-level laser light therapy (LLLT)
  • Low-power laser therapy (LPLT)
  • Non-thermal LED light.
  • Soft laser therapy
  • Cold laser therapy
  • Biostimulation, photonic stimulation
  • Photobiomodulation


    How Does Red Light Therapy Work? 

    Red light therapy involves irradiating your skin with red and near-infrared light at a low intensity for a given period. This exposure may have a biochemical effect on your cells, making the cell's powerhouse, the mitochondria, more robust. RLT might achieve this by enhancing the flow of electrons, oxygen uptake, and ATP (adenosine triphosphate) levels.

    When the cell's energy center gets a boost, it means that the cells can function optimally, as they are designed to do, such as repairing and growing.

    To explain the effectiveness of the procedure, compare red light therapy to skin devices, including lasers and intense pulsed light (IPL). Lasers work by deliberately wounding the skin to induce an inflammatory response in order to decrease wrinkles and redness. On the other hand, red light therapies do not break the skin, so positive outcomes are observed with no pain, inflammation, or redness associated with laser treatments.

    In other words, red light therapy penetrates the deepest below the skin without hurting cells to stimulate them. (Learn more about tissue penetration depths of different wavelengths)

    Types Of Red Light Therapy Devices

    • LED Therapy Devices:

    Uses light-emitting diodes to boost collagen and improve overall skin texture. 

    • Laser Therapy Devices

    Targets specific skin issues, such as reducing fine lines or scars, with a concentrated beam of light. For example, the JOVS Slimax anti-aging device uses 25 beads of 660 nm red light, along with micronutrient technology, to offer stronger penetration.

    • Infrared Light Therapy Devices:

    Has a wavelength range in 950-1200 nm and penetrates the deepest into the skin. It enhances rejuvenating experience by promoting cell healing inside out.

    If you need treatment for the skin surface and the deeper tissues, then a combo of red light and infrared light in a single device is the best option to buy for various treatment needs. JOVS 4D red light mask has both red and infrared light, outperforming any other facial mask with the deepest penetration. Save your bucks from clinical RLT and get the desired results at home. 


    Benefits of Red Light Therapy

    When applied deep into the dermis, RLT has been proven to rejuvenate aging skin by stimulating fibroblasts, regulating inflammation, and even controlling sebum secretions. Let's explore the other benefits.

    Increases Collagen Production

    The anti-aging properties of active ingredients, such as collagen, can help remove fine lines and wrinkles, making the skin appear younger.

    Enhanced Sports Performance In Athletes

    RLT has been shown to heal and regenerate damaged muscle tissues and increase muscle mass after training. This can help increase sports performance

    Treat Acne

    RLT increases the turnover of skin cells that make up the top layer of skin and reduces inflammation. Thus, it helps improve acne.

    Enhanced Absorption Of Skincare Products

    RLT can enhance the efficiency of topical skincare products because more blood flow and cell activities mean better absorption.

    Reduces Body Fat

    Laser-based therapy devices are useful for body contouring treatments and reducing fat deposits. However, some studies show no significant changes. 

    Reduces Inflammation

    Red light also has anti-inflammatory effects, so it can reduce inflammation and redness. This makes it useful for people with skin issues such as acne, rosacea, or eczema, for example.

    Tightens The Scalp And Increases Hair Thickness

    RLT may be used to treat alopecia as it promotes more blood flow to the scalp. This increases cell activity, which in turn gives hair follicles more nutrients. 


    Applications Of Red Light Therapy

    Red light therapy devices are particularly useful for a wide spectrum of medical and aesthetic dermatological concerns. The JOVS 4D Laser Mask has helped many people achieve their skin goals. It reduces redness and brightens the skin while treating blemishes and dark circles in less than four weeks.

    Since RLT reduces inflammation and repairs tissue, it can be used for multiple conditions, such as:

    • Eczema and psoriasis
    • Acne and breakouts
    • Fine lines and wrinkles
    • Androgenetic alopecia 
    • Skin fibrosis/scarring
    • Treat chronic conditions, i.e., fibromyalgia
    • Fat loss
    • Sports injuries

    It is to be noted that most of the research is limited and has yet to be deeply studied.



    Red Light Therapy, Aka photobiomodulation or low-level light therapy (LLLT), is a therapeutic procedure that has been proven to be effective in treating acne, fine lines and wrinkles, alopecia, and some other skin and health issues. It is important to understand how JOVS red laser masks work if one is to take full advantage of the technology behind them.
