Red light therapy (RLT) is a non-invasive treatment that uses red low-level light wavelengths to treat a variety of skin and health disorders. This blog provides an in-depth look at its benefits, procedures, applications, and considerations.
Understanding Red Light Therapy: Fundamentals and Mechanism
Red light therapy (RLT) is a procedure that supposedly improves the appearance of your skin by reducing wrinkles, scars, redness, and acne. It is also said to treat other medical ailments. To date, there has been a lot of continuing research, the publication of tiny studies, and significant internet discussion about the effectiveness of red light therapy for a variety of health purposes. Some studies have shown promising results, but the overall efficacy of red light treatment is unknown. Other names used to describe red light therapy include:
-
Laser light therapy is used at low levels.
-
Low-powered laser therapy.
-
Non-thermal LED lighting.
-
Soft laser treatment.
-
Cold laser treatment.
-
Biostimulation and photonic stimulation.
-
Photobiomodulation and phototherapy.
The Science Behind Red Light Therapy
Pain relief without medication or surgery may sound too good to be true, but red light therapy provides just that. Red light therapy employs photobiomodulation, a low-level laser therapy that directs red and near-infrared light to specific areas of your body. This helps regenerate (or grow back) cells, restore cell function, and stimulate blood flow. As a result, it promotes healing and alleviates pain. Photobiomodulation was discovered approximately half a century ago. It is now used to treat a wide range of ailments, some of which occur concurrently. It relaxes muscles, thereby relieving spasms, pain, and stiffness. It has a similar effect on the joints, reducing aches, pains, and stiffness.
How Red Light Therapy Works at the Cellular Level
This red light exposure may have a good biochemical effect on your cells, strengthening the mitochondria, which is where the cell's energy is generated. RLT may achieve this by boosting electron transport, oxygen consumption, and ATP levels. Cells can perform more efficiently, regenerate, and repair themselves by increasing their mitochondrial energy. LEDs are replacing lasers as the preferred RLT light source since they are nonablative and nonthermal. Furthermore, according to the study, they may help:
-
Increase blood flow.
-
Reduce inflammation.
-
Increase collagen levels.
-
Increase the production of fibroblast
Key Benefits of Red Light Therapy
Red light therapy is now being used to treat athletes at all levels, from major league baseball to elite athletes. However, its advantages go well beyond the court, pool, and track. Its primary advantages include improved joint mobility and less muscle discomfort. More specifically, red light therapy can help with:
-
Enhance wound healing and tissue repair.
-
minimize the side effects of some cancer treatments, like lymphedema, radiation dermatitis, and oral mucositis
-
Improve hair growth in people with androgenic alopecia.
-
Treat carpal tunnel syndrome in the short term.
-
Reduce the progression of myopia.
-
Reduce psoriasis lesions and burn scars.
-
Reduce neuropathic pain.
-
Improve neural function and protection to improve cognition and memory in people with Alzheimer's disease
-
Improve skin complexion and build collagen to reduce wrinkles.
-
Relieve pain and inflammation in people experiencing Achilles tendon pain.
RLT can also be combined with photosensitizing medications to help treat certain types of cancer. This is referred to as photodynamic therapy. In this type of therapy, the light only acts as an activator for the medication.
Practical Uses of Red Light Therapy in Skincare
Red light therapy (RLT) is a new treatment that shows promise for healing wrinkles, redness, acne, scars, and other indications of aging. Many researchers believe more clinical trials are required to demonstrate its efficacy as a treatment.
Anti-Aging and Skin Rejuvenation
-
Anti-Aging: The aging process of the skin is unavoidable, but it can be mitigated, especially in cases where environmental factors contribute to changes in the skin. A key component of any skincare regimen should be the regular application of broad-spectrum photoprotection to prevent UVR-induced accelerated skin aging. Topical antioxidant products can be used in addition to this to offer extra photoprotection and possibly counteract other oxidative stressors like air pollution. Optimizing barrier function through the use of simple emollients can also help: a healthy stratum corneum is the first line of defense against environmental assaults. Topical retinoids and some peptides, in addition to epidermal effects, show dermal repair with a more profound clinical impact on deeper cutaneous wrinkles, though cellular changes will take months rather than days.
-
Skin Rejuvenation: Red light therapy for scars and other skin conditions is based on the cellular revitalization process. This novel treatment uses the power of specific wavelengths of light to penetrate the skin and target the mitochondria, the energy powerhouse within cells. Red light therapy improves mitochondrial function, particularly in the production of ATP (adenosine triphosphate). ATP is the primary energy carrier in all living organisms, so increased production results in more energized and efficient skin cells. As these cells rejuvenate, they improve the overall health and appearance of the skin, making it appear more vibrant and youthful. This process not only helps to repair damaged skin cells but also promotes the growth of new cells, which improves skin texture and reduces the visibility of scars and imperfections. The therapy is non-invasive, requires no downtime, and can be an easy and effective addition to skincare routines, especially for those with aging or scarred skin.
Red Light Therapy for Acne Treatment
Red light therapy includes exposing the skin to low-level red light wavelengths, which are commonly delivered via LED devices. Light enters the skin and affects biological processes, which may aid in the following ways:
-
Red light can help reduce inflammation, which is a major cause of acne. By reducing inflammation, it can help to reduce the severity of acne lesions.
-
Acne-causing bacteria (Propionibacterium acnes) can be killed by certain wavelengths of light.
-
Red light therapy can help heal acne lesions by increasing blood circulation and stimulating collagen production.
Improving Skin Texture and Tone
Red light therapy does more than only reduce wrinkles; it also improves skin texture. This treatment enhances even skin tone and reduces the appearance of pores, resulting in a smoother, more refined complexion. As a result, blood flow increases and pore size decreases, improving the smoothness of the skin's surface. Furthermore, the light promotes the replacement of damaged cells with new ones, resulting in improved skin texture and clarity.
