Most of the phototherapy devices on the market use LED light. This is not some low-end technology, but a serious skin phototherapy technology used in clinical practice.
The principle is to use high-purity, specific wavelength light for beneficial photobiological regulation.
The energy and wavelength of light are different, and the biological reactions that can occur after entering the skin are also different. It is often used in hospitals to improve acne, damaged skin barrier, facial pigmentation, etc.
So what requirements does a good LED Phototherapy Facial device need to meet?
It needs to meet the following criteria:
- High energy: within the range of skin tolerance and no eye damage, the higher the energy, the better.
- High light purity: no light harmful to the skin can be mixed in.
- The energy distribution of the light beam is uniform enough: the skin can also receive light uniformly.
- The light decay period should be long: that is, the lower the effectiveness decay rate of various skin care lights, the better, which means that the life cycle of the spectrometer is also longer.
What is LED Phototherapy Facial Device?
LED light therapy machine is a therapeutic operation that uses the sterilization and anti-inflammatory effects of light radiation, accelerates blood circulation, promotes tissue regeneration, improves metabolism, etc. to assist in the treatment of diseases. It is an external treatment method, and through a certain period of irradiation, it can achieve the purpose of treating related diseases. It is commonly used in clinical practice for the auxiliary treatment of soft tissue injuries, soft tissue inflammation, chronic skin ulcers, burns, pityriasis rosea, psoriasis and other diseases.
LED phototherapy facial device has the advantages of short treatment time, quick effect, gentle and safe process, and zero burden on the skin. Through the red, blue, yellow, green and other lights in the narrow spectrum light source, it penetrates the skin and improves problematic skin. Such as spots, aging skin, oily skin, sensitive skin, acne skin, etc.
LED light types theory and applications.
Red light promotes repair.
The red light has a wavelength of 633nm and has strong tissue penetration ability. It is known for its high purity, strong light source and uniform energy density. It mainly promotes the dissipation of inflammation, and its depth of action can reach the hair follicle sebaceous gland unit. It is more used to treat acne. The red and blue light we often hear about is the 633nm red light and the 415nm blue light. The 415nm has an advantage in sterilization but cannot solve the inflammation, while the 633nm can supplement and solve the inflammation of the hair follicle sebaceous gland unit, and at the same time promote healing and repair.
Effect: Anti-inflammatory and repair skin barrier.
Principle: Penetrates the skin deeply, promotes the synthesis of glycogen and protein, thereby promoting cell metabolism, improving blood circulation, promoting inflammation absorption and wound healing.
Clinical application scope: Treatment of skin diseases such as skin infection, skin ulcer, folliculitis, furuncle, erysipelas, alopecia areata and postherpetic neuralgia.
Blue light anti-inflammation and sterilization.
The wavelength of blue light is 415nm, which has short wavelength, high frequency and high energy, but relatively weak penetration ability. It is mainly used to improve inflammatory acne, papules and pustules. Some patients with seborrheic dermatitis occasionally use this wavelength for treatment.
Effect: Antibacterial and anti-inflammatory, inhibit sebaceous gland oil secretion, purify skin, activate cells, and promote protein synthesis.
Principle: It has the effect of quickly inhibiting inflammation. In the formation process of acne, Propionibacterium is mainly at work, and blue light can efficiently destroy this bacteria without damaging the skin, minimizing the formation of acne.
Clinical application range: acne.
Yellow light soothes and reduces spots.
The wavelength of yellow light is 590nm, which can promote blood circulation, promote skin cell metabolism, and brighten skin tone. It mainly regulates some immune cells in the epidermis, reduces the release of inflammatory mediators, and promotes the dissipation of superficial inflammation. It is more suitable for patients with allergies and dermatitis.
Function: Promote cell metabolism and reduce the excitability of peripheral nerve fibers.
Principle: It can be quickly introduced into subcutaneous tissue to produce a highly efficient photochemical reaction – enzymatic reaction, increase cell activity, promote cell metabolism, and improve skin immunity.
Clinical application range: capillary dilation, desensitization, relaxation, dark yellow complexion.
Infrared light relieves pain and stops bleeding.
Infrared light: 830nm
Effects: promote exudate discharge, reduce swelling, relieve pain, reduce inflammation, etc.
Principle: Irradiation promotes intermolecular vibration to produce photothermal effect, which plays the role of exudate discharge, reduce swelling, relieve pain, reduce inflammation and improve local nutrition.
Clinical application range: eczema, neurodermatitis, skin ulcers, soft tissue trauma, bedsores, etc.
LED light therapy machine facial beauty projects:
1. Whitening management.
Whitening products + yellow light from LED spectrometer: In whitening management, skin care products containing whitening ingredients are generally used with the yellow light of LED spectrometer to promote the absorption of whitening ingredients. At the same time, the yellow light penetrates the skin to effectively relieve skin redness and swelling, fade spots, and further whiten the skin.
2. Anti-aging management.
Anti-aging products + red light from LED spectrometer: Aging skin lacks collagen and cell growth slows down. Use anti-aging products to replenish the moisture needed by the skin. The red light from the LED spectrometer speeds up skin metabolism, promotes cell self-regeneration and repair, reduces wrinkles, and delays aging.
3. Oil control & acne management.
Products containing salicylic acid or other acidic ingredients + alternating red and blue light from LED phototherapy:
Apply acidic skin care products to the face, cover with plastic wrap, and use the blue light of LED spectrometer to inhibit bacteria, reduce inflammation and calm the skin.
Apply a moisturizing mask and use the red and blue light of LED phototherapy to alternately irradiate the skin to promote skin growth, repair acne skin and wounds, and restore skin health.
4. Sensitive skin management.
Calming functional mask + green light of LED light therapy device: Using a skin care mask with good calming, anti-inflammatory and skin repairing effects, combined with the green light of an LED light therapy device, can further calm the skin, reduce skin sensitivity and restore skin health.
Notes on LED Phototherapy Facial Treatment:
Before treatment:
LED light therapy is widely applicable, but not for all people. The following types of patients should consult a doctor in detail before treatment and decide whether to undergo treatment based on their own situation.
- For pregnant women, red, blue, and yellow light should be used with caution.
- People with photosensitivity, porphyria, and albinism should not use it.
- Patients who are taking photosensitivity drugs should not use it either.
During treatment:
During LED light therapy, patients need to take the following safety and comfort measures:
- Patients will be given an eye mask to protect their eyes and must wear it during treatment.
- The doctor will adjust the treatment plan according to the condition (mainly: treatment wavelength, intensity, power density, output method, treatment mode).
- Patients should maintain a comfortable position during treatment and cannot move at will.
After treatment:
After LED light treatment, patients should pay attention to the following care measures:
Moisturizing and sun protection: Moisturizing is required after treatment. It is recommended to apply sunscreen or wear a sun hat when going out to protect the skin from long-term exposure to ultraviolet rays and reduce the risk of pigmentation.
Dietary adjustment: Avoid eating spicy and irritating foods to avoid affecting the normal recovery of the skin. At the same time, the intake of fresh vegetables and fruits should be increased to supplement the necessary vitamins, which will help the repair and healing of the skin.
FAQs about LED Phototherapy Facial device.
Q: Why do we use LED phototherapy for treatment?
A: The narrow spectrum light irradiated by the phototherapy device will produce a chemical reaction of light when it comes into contact with the skin, thereby improving the skin quality.
For example: the enzymatic reaction increases the activity of catalase (Catalase) and superoxide dismutase (SOD) which serve as the “guard” and “cleaner” of cells, promotes cell metabolism and accelerates differentiation and proliferation, stimulates the secretion of alkaline fibroblast growth factor and epidermal growth factor in our body, promotes the regeneration and rearrangement of collagen fibers and elastic fibers, and can improve skin roughness, promote wound healing, remove wrinkles and rejuvenate the skin.
It can also reduce the formation of melanin, kill Propionibacterium acnes, eliminate inflammation, increase the content of vitamin D in the human body, and achieve the effects of whitening, removing spots and removing acne.
Q: What functions does the LED phototherapy device have?
A: [Calcium supplement function] (its wavelength is 320nm), increases the body’s vitamin D3 content, improves the metabolic balance of calcium and phosphorus ions, and increases bone density.
Orange light (610nm) promotes blood circulation and accelerates metabolism;
Purple light (308nm) can stimulate the secretion system, smooth lymph nodes, repair skin, mucosal ulcers and acne.
Red light (635nm) Red light improves fine lines and acne, and heals wounds!!
Blue light (415nm) improves allergies, acne, and skin oil, improves the effect of acne and acne, and relieves pain.
Yellow light (590nm) improves dullness, dark yellowness, and spots!!
Green light (560nm) improves red blood and redness!
When using the LED phototherapy machine for facial treatment, you need to cover with cotton pads and wear an eye mask.
Q: What do you need to use with LED light therapy?
