LED Therapy- A Serious player in the anti-ageing game
LED therapy has been in the shadow of Fillers and neuromodulators (aka Botox) in aesthetic medicine for sometimes, but because more conclusive scientific publications are being released, it is gaining more attention. The diversity of its application and affordability are increasing a popularity of this treatment.
What is LED?
Led stands for Light Emitting Diode. A certain wavelength of light penetrates to deferent skin layers modulating various biological processes in the cells. Known for more than 40 years, LED become extensively researched by NASA which found that use of low levels of visible or near infrared light can be used to promote deep wound healing, reduce pain and inflammation and prevent deep tissue damage. This is how LED turn out to be a permanent “Resident “on space shuttles protecting astronauts from effects of low gravitation( osteoporosis, sarcopenia) and helping in deferent healing processes.
How does it work?
LED treatment works by using a selection of bright light-emitting diodes that send low- level light into the skin and deeper tissues. It usually combines yellow, blue, red, green and infrared light as they all have different properties and effect on biological systems.
- Yellow is a color of anti-aging! It triggers skin regeneration by stimulating the fibroblast to increase a production of collagen and elastin. It is a sufficient for reducing dilated pores and fading scars. This color is also effective for eczema.
- Red color has antiseptic, anti-inflammatory and analgesic properties. It stimulates the proliferation of fibroblasts and the production of growth factors and therefore has in an impact on inflammation and healing of any wound, post laser skin erythema etc. It can decrease any pain including burn’s pain (where also help with inflammation). It has a systemic effect by promoting blood circulation and stimulating the liver for detoxification.
- Blue color has antiseptic properties and has been used in treating acne by destroying Propionibacteria Acnes that was proven in many scientific publications. It has a good effect on Allergic rhinitis and systemic impact on regulating thyroid function.
- Infrared is a color with a deep penetration, up to 3 to 4 cm and has a good effect on adipose cells, bones, and joints. It has an effect on fibroblasts that stimulates collagen and elastin but also on ATP (energy molecule) production. Patients feel very energized after using this color. It can relieve the pain when treating sub-acute or chronic inflammatory musculoskeletal conditions and muscle pains (such as fibromyalgia)
- The green color is a refreshing and restorative color! It is absorbed by the melanin, and it can be used to reduce hyperpigmentation (melasma, postinflammatory hyperpigmentation, etc.) Systemically it can be used for depression, bulimia, psychosomatic trauma, irritability etc.
The most usual indications in aesthetic and dermatology practice for LED use are
- Photo-aging (face and body)
- Stretch marks
- Hair loss
- Pain (bone & muscle)
- Allergic rhinitis
- Burns and sunburn
Why do we trust LED?
Since The first Food and Drug Administration (FDA) approval for laser diode phototherapy that was granted in 2002, LED has undergone many studies to prove its efficacy.
One critical study demonstrated that blue and red light is an effective, safe and non-painful treatment for mild to moderately severe acne. Twenty-four patients with mild to moderately severe facial acne were treated during four weeks, showing 78 %, improvement of acne, melanin levels significantly decreased after treatment ( pigmentations ) and brightened skin tone with better skin texture were spontaneously reported by 70% of patients. Providing we identify the real cause of acne such insulin resistance, gut inflammation and dysbiosis, the presence of genetic SNPs that compromise liver detoxification, high cortisol, DHT receptor high activity, etc. LED can be used to complement medical treatment. Unfortunately, acne is always an internal problem manifesting on the skin. Similarly, Rosacea reacts very well to LED therapy, but for sustainable improvement, it needs to be combined with medical interventions such the on for a leaky gut.
Skin rejuvenation is an important indication that has been comprehensively researched. It is used for photodamaged skin in a safe and noninvasive manner. The study showed that good skin rejuvenation is firmly based on the wound healing process particularly neocollagenesis (new collagen production). Patents typically need series of treatments that simply entail laying under the LED light.
One other indication of a remarkable improvement that created LED a position of a serious participant in aesthetic medicine “game” is stretch marks. A recent study concluded that if used in the precise protocol with a designated wavelength LED can improve up to 80% of stretch marks, including very old one. Once again safe and non-invasive approach makes this treatment particularly accepted by teenagers suffering from stretch marks.
LED can be used for all types of hair loss: common alopecia, female pattern baldness-, male androgenic alopecia, Telogen Effluvium after a high fever, pregnancy, taking medications or severe diet, traction alopecia, Alopecia areata. Identifying and addressing the underlying cause of hair loss in combination with LED gives good results, providing one has the patience to wait 4-9 months for regrowth.
Postoperative scars and injury scars, Psoriasis, pigmentations, leg ulcers (diabetic, venous,), shingles pain, etc. are few to mention that have scientific studies, proving LED efficacy.
Fortunately, you don’t have to be an astronaut to experience full potential and efficacy of LED; it is commonly available in many reputable aesthetic and dermatology clinics for your use.
