Origins of Scars - The Story Behind Red Light Infrared Therapy

Create on January 7, 2023

Scarring is a natural process that happens as the body heals itself following skin damage, such as from a wound or skin cancer treatment. The skin naturally produces new cells to replace those that have been damaged or destroyed, which leads to scar formation. Red light therapy infrared is an effective treatment for scars that helps promote healing and reduce inflammation, two important factors for scar healing. Are you one of the sufferers of scars? Here, we’re talking about the origins of scars and how near infrared light therapy device helps scar removal effectively.

The origins and formation of scars

Tissue healing following injury is a complex phenomenon requiring intricate and coordinated systems. The healing process begins as soon as a wound is created, leading to the (partial) restoration of the wounded tissue. Three dynamic, connected, and temporally overlapping phases make up wound healing. These phases are categorized as the inflammatory phase, the proliferative phase (with the development of the granulation tissue and reepithelialization phase), and the remodeling phase, which includes maturation and scar formation.

These phases are based on morphological changes seen in the wound tissue during the course of the healing process. The third stage of healing, scar formation, entails gradual modification of the granulation tissue. Proteolytic enzymes, particularly the family of matrix metalloproteinases (MMPs) and their inhibitors (tissue inhibitors of metalloproteinases [TIMPs]), play a significant role in this process.

Sometimes the healing of wounds takes a pathological course, leaving behind pathological scarring. Such improper healing processes could be the result of poor granulation tissue remodeling, which could lead to, for instance, faulty skin repair that results in hypertrophic or keloid scars as well as fibrosis in internal organs. In the case of excessive scarring in the skin, such as hypertrophic scars, normal healing fails and the granulation tissue continues to expand. This is most likely because of abnormal and excessive growth factor secretion and/or a lack of molecules necessary for inducing apoptosis or remodeling of the extracellular matrix during normal healing. The excessive extracellular matrix is deposited when the stimulus triggering the reaction to damage remains in the internal organs. Organ fibrosis results from the excess buildup of extracellular matrix. The formation of fibrosis and its chronic nature may be a result of an imbalance between matrix deposition and matrix breakdown, as is seen in pathological healing in the skin.

How effective is professional red light therapy in treating scars?

The mechanism behind red light panels is photobiomodulation (PBM light therapy), which has become a lot clearer in recent years. The primary influence of red light therapy at home for skin and body originates from the modulation of mitochondrial, intracellular, and nuclear processes, which alter downstream cellular processes involved in skin fibroblast proliferation. For example, fibroblast proliferation is critical for the development and maintenance of dermal fibrosis, and controlling fibroblast proliferation is an important therapeutic strategy for treating skin fibrosis. This study has verified that red light therapy lamps can inhibit fibroblast proliferation in a dose-dependent manner.

According to the vitro data of this study, red light therapy lights at high fluences, defined as greater than 160 J/cm^2, inhibits human skin proliferation, collagen production, and translocation rate, resulting in an anti-fibrotic skin effect.

The downstream pathways from best red light therapy panels have been illustrated in the following picture, as well as described in this research.

SMAD7 activation acts as a negative feedback loop and inhibits TGF-B1 signaling. 8SMAD signaling alters COL1A1 gene expression, resulting in altered extracellular collagen deposition and altered fibroblast proliferation. Furthermore, SMAD signaling contributes to collagen deposition and the pathogenesis of dermal fibrosis.

It is proposed that these alterations in proliferation may be the result of changes in the redox state of fibroblasts treated with laser red and near infrared LED light therapy.

Bestqool：best home red light therapy near me

Red laser light therapy is a relatively new form of scar treatment that uses red and NIR light therapy to stimulate the natural healing process. Bestqool therapy devices include everything you need for getting the most from red light therapy benefits. To find the best red light therapy at home device for your needs, the following tips will help you identify the right medical-grade red light therapy device for you.

1. Targeted or systematic treatment: Bestqool devices provide both half or full-body LED light therapy devices and targeted devices for specific medical conditions. Full-body devices are designed for significantly broader coverage, allowing for the treatment of a larger area in a short period of time, whereas targeted devices treat a relatively limited area of the body. This is determined by the area of treatment—the place affected by scars.
2. Specific wavelengths proven by clinical studies: In several peer-reviewed studies, experts in phototherapy and scientists of photomedicine have discovered that a small band of red and near infrared light is the optimal wavelength for safety and health benefits. Ideal wavelengths for red light are in the mid-600 nm range, and for near-infrared light, in the mid-800s. Bestqool red light devices are designed based on scientific evidence to provide the most effective wavelengths in the optical window of human skin (660 nm red light and 830 nm near-infrared light). The higher the concentration of the wavelength band and the greater the coherence of the light source, the better the therapy's performance. It is not necessary to have a wide combination of wavelengths, but in fact, this results in the deterioration of the therapeutic properties of light.
3. Safety standards and design: any medical-grade at home infrared light therapy that are meant for human use should be designed in accordance with Good Manufacturing Practice (GMP) under quality management systems like ISO 13485 or MDSAP. Infrared therapy devices devices should be certified for safety in accordance with the medical standard IEC 60601-1 as well as any additional or specific standards that are deemed relevant by the regulatory body where the device is sold. Bestqool FDA approved red light therapy abide by these standards, and with the support of FDA clearance and ETL certification, Bestqool professional led light therapy machine are able to ensure both safety and effectiveness for the positive experience of red light home therapy. As one of infrared therapy lamp, the claims of effectiveness and safety of Bestqool devices have passed the guarantee of the authoritative body. With a 3-year warranty, it is Bestqool’s promise to safeguard customers against any shopping risk.
