Led light - photobiomodulation
What is photobiomodulation using LED light?
An aesthetic medicine technique called photobiomodulation by LED light uses cold light to stimulate cell regeneration and improve the appearance of the skin. LED photobiomodulation, also known as LED therapy or LED biophotomodulation, allows you to deeply rehydrate and tone the skin, repair skin damaged by the sun, laser, peels and treat large areas of the skin in all seasons, such as the face, neck, décolleté, scalp, hands and even the entire body. There are many indications for hydration, complexion radiance, tightening pores, sagging skin, early scarring such as stretch marks, burns, sunburn, acne and slowing down baldness .
In dermatology, LEDs applied to the face are increasingly used to treat fine lines and wrinkles, rosacea, eczema and inflammation after a peeling treatment. The ability of cells, via mitochondria, to respond to pulsed and chromatic light is the basis of photobiomodulation. In non-thermal doses, this therapy uses non-ionizing light sources such as laser, light-emitting diodes (LED), and broadband visible light in the visible and near-infrared spectrum.
How does photobiomodulation using LED light work?
LED light photobiomodulation works by using different specific wavelengths for synergistic action, such as blue, yellow, red and infrared (IR) for multispectral phototherapy. LEDs emit cool light that penetrates the deeper layers of the skin and encourages the cells' mitochondria to produce energy and stimulate cell regeneration. In biomedical research, photochemical reactions are well known, and photobiomodulation uses the first law of photochemistry (Grotthuss-Draper law) which states that a chemical substance must absorb light for a photochemical reaction to occur. For photobiomodulation, the generally accepted theory is that this chemical is the respiratory enzyme cytochrome C-oxidase which participates in the electron transport chain in the mitochondria.
What are the benefits of LED light therapy?
LED light therapy has many benefits for the skin and overall health. Here are some of the most important benefits:
Cell regeneration: LED light increases the production of collagen and elastin, which which improves the firmness and elasticity of the skin.
Hydration: LED light therapy deeply rehydrates the skin, improving the appearance of dry skin and lips.
Repair of skin lesions: By stimulating cell regeneration, LED light helps heal wounds wrinkles, fine lines and stretch marks.
Acne Treatment: Light-emitting diode (LED) light therapy can help reduce inflammation and clean pores, which can improve the appearance of acne.
Slowing down baldness: LED light can slow down hair loss by increasing the hair growth and strengthening the skin of the head.
Improved microcirculation: Cellular detoxification, or LED light, can eliminate free radicals, which can be toxic to Propionibacterium acnes and improve the appearance of acne.
Elimination of free radicals: The microcirculation of the dermis is improved by LED light, this which improves healing and intra/extra-cellular exchanges.
Sleep: Light therapy can improve sleep quality by reducing restlessness and reducing episodes of sleepiness during the day.
Are there any side effects of photobiomodulation?
Photobiomodulation, also called low energy laser therapy (LLLT), is a non-invasive method that is generally considered safe and has no side effects identified so far, according to the sources consulted.
How many light therapy sessions are needed for visible results?
The effects of light therapy are generally felt after several days of use. Normally, one or two sessions are scheduled per week for four to six weeks. From the third or fourth session, the results of the LED treatment are visible. However, the number of sessions and frequency should be determined with your beautician based on your individual needs and depend on the desired goal.
Which areas of the face can benefit from LED light?
LED light can be used to illuminate different parts of the face. The following areas can benefit from LED light:
The upper third of the face: LED light can be used to reduce fine lines and forehead and eye wrinkles.
Cheekbones: LED light can correct redness and improve the appearance of your blush .
Neck: LED light can improve the texture and smoothness of the skin in the neck.
Dark circles under the eyes: LED light can reduce dark circles under the eyes.
Lips: LED light can improve the appearance of lips, increase their volume and reduce fine lines and wrinkles.
How long does a photobiomodulation session last in Tunisia?
In Tunisia, the duration of a photobiomodulation session generally varies between 15 and 45 minutes, depending on the nature of the treatment and the targeted areas. For example, an LED phototherapy session for the face can last around 15 minutes, while an LED photomodulation session for the face can last from one minute to half an hour, depending on the nature of the skin. patient.
Can light therapy be combined with other aesthetic treatments?
Light therapy, also called photobiomodulation, can be used with other aesthetic treatments to improve the results and reinforce the effect of each of them. Here are some examples of treatments that can be combined with light therapy:
Injections: Light therapy can be combined with injections of filler, medium glass or of PRP to improve the appearance of lines and fine lines.
Peelings: Skin peels can be combined with light therapy to stimulate regeneration cellular and reduce inflammation caused by peels.
Mesotherapy: Light therapy and mesotherapy, which consists of injecting hyaluronate into the tissues , can be combined to improve skin hydration and reduce the appearance of wrinkles.
PRP injections: Light therapy and platelet-rich plasma (PRP) injections can be combined to stimulate cell regeneration and improve the appearance of the skin.
Are the results of LED therapy lasting?
When used regularly and combined with maintenance treatment, LED light therapy can provide long-lasting results. To ensure the results last, 5 to 10 sessions, spaced one to two weeks apart, are recommended, followed by a maintenance treatment once a month.
