Portable 633nm Red Light Therapy Devices

Introduction for Portable 633nm Red Light Therapy Devices

Effective treatment delivery in photodynamic therapy (PDT) requires coordination of the light source, the photosensitizer, and the delivery device appropriate to the target tissue. Lasers, light-emitting diodes (LEDs), and lamps are the main types of light sources utilized for PDT applications. The optical properties of tissue also affect the distribution of the treatment light. Treatment light undergoes scattering and absorption in tissue. FonyMed uses the best LED lights source which is imported from Japan. 5 times higher quality and longer lifespan than others.

Working Theory for Portable 633nm Red Light Therapy Devices

PDT requires accumulation of a photosensitizer in the treatment target tissue. Route of administration depends on the treatment site and photosensitizer. Photodynamic interactions start with the activation of the photosensitizer by the treatment light of the appropriate photosensitizer-specific wavelength. The absorption wavelength of the photosensitizer must be matched by the wavelength of the light source. Most commonly used photosensitizers have multiple absorption peaks (several Q-bands in the red (600–700 nm) and the Sorbet band in the blue (~400 nm)); however, a longer wavelength light source is preferred due to the deeper penetration of the light in tissue which allows treatment of a greater target tissue.

Functions for Portable 633nm Red Light Therapy Devices

• 1.Blue Light Therapy for Acne & Blemishes & Eczema – Blue light (415nm) in this wavelength has proven to have highly powerful bacteria fighting properties. Moreover, this light can kill P. acnes, one of the primary acne causing bacteria, meaning that it can be a very effective treatment for mild to moderate acne conditions. Blue light LED can also help to stabilize oil glands, ease inflammation, and purify the skin.

• 2.Green Light Therapy – Hyperpigmentation, Freckles & Age Spots. Green light (530 nm) is absorbed by the melanin producing cells of the skin, slowing melanin production, and gradually breaking up excess melanin collections which are then reabsorbed by the body. Green light is known to have a highly calming effect on the skin.  It can also brighten the complexion by helping to lighten areas of hyperpigmentation, freckles and age spots.  At the same time, green light photo facials can soothe the skin’s surface with its anti-inflammatory properties.

• 3.Amber Light Therapy for Spider Veins & Red Spots – Amber red light (640 nm) is used for its reduction in inflammation, swelling, and redness on the face including broken capillaries and spider veins.  It is often chosen for the treatment of sunburns and other types of burns, as well as conditions such as rosacea. Amber light therapy can help to bring vitality back to complexions that have become dull looking. It can bring back a more youthful “glow”.

• 4.Red & Infrared Light for Collagen Production & Elimination of Fine Lines & Wrinkles

• Red Light Therapy – (620 nm to 700 nm) Red light has the unique ability to penetrate deeply into the skin, where it can stimulate collagen production, rejuvenate the face, encourage cellular repair, and boost the circulation to the face so that the complexion appears more youthful and vibrant.  Red light photo facials are used for reducing scarring, wrinkles, deep lines, and evening out the skin tone.

Advantages for Portable 633nm Red Light Therapy Devices

Phototherapy (light, lasers, and photodynamic therapy) has been proposed as an alternative therapeutic modality to treat acne vulgaris and was proposed to have less side effects compared to other treatment options. Exposure of sunlight was reported to be highly effective for treatment of acne with efficacy up to 70%. The sunlight decreases the androgenic hormones in the sebaceous gland, but the unwanted effect of exposure to UVA and UVB limits sunlight for the treatment of acne. Recently, phototherapy with visible light (mainly blue light, red light or combination of both) started being used in the treatment of acne. Acnes as a part of its normal metabolism, and that act as endogenous photosensitizers.

This process causes a photochemical reaction and forms reactive free radicals and Singlet oxygen species which in turn lead to bacterial destruction. Red light is known to penetrate deeper in tissues when compared to blue light.50 It has been demonstrated that red light can affect the sebum secretion of sebaceous glands and change keratinocyte behavior.54 Furthermore, red light might also exert its effects by modulating cytokines from macrophages and other cells, which in turn could reduce inflammation.

Benefits for Portable 633nm Red Light Therapy Devices

Among patients who received LED photorejuvenation alone, 90% reported that they observed a softening of skin texture and a reduction in roughness and fine lines ranging from a significant reduction to sometimes subtle changes. Moreover, patients receiving a thermal photorejuvenation laser with or without additional LED photomodulation reported a prominent reduction in post-treatment erythema and an overall impression of increased efficacy with the additional LED treatment. This reduction in post-treatment erythema could be attributed to anti-inflammatory effects of LLLT. Using different pulse sequence parameters, a multicenter clinical trial was conducted, with 90 patients receiving 8 LED treatments over 4 weeks. The outcome of this study showed very favorable results, with over 90% of patients improving by at least one Fitzpatrick photoaging category and 65% of patients demonstrating global improvement in facial texture, fine lines, background erythema, and pigmentation. The results peaked at 4 to 6 months following completion of 8 treatments.
