According to the Grand View Research: Light Therapy Market Report, with the growing demand for non-invasive and non-drug treatments such as seasonal affective disorder (SAD), insomnia, skin diseases, and medical beauty, more and more countries are beginning to adopt light therapy equipment to treat diseases. The global light therapy market size in 2020 is US$1 billion, and it is expected to grow at a rate of 4.7% from 2022 to 2030, reaching US$1.44 billion by 2030. With the market outlook looking good, many medical institutions and beauty clinics have introduced LED light therapy beds. However, the quality of LED light therapy beds on the market varies, and choosing the most suitable device is crucial. This article will deeply analyze the scientific principles and actual effects of four mainstream light therapy beds to help you make a more informed choice.
LED light therapy beds usually use different wavelengths of light for treatment, and each light has its unique biological effect. The following are the main differences and effects of red light, blue light, green light, and yellow light:
|
Types of wavelength |
Wavelength range (nm) | Main effect | Target group |
| Red light | 630-850 | Promote cell regeneration, stimulate collagen synthesis, reduce inflammation, relieve pain, and accelerate wound healing | Skin anti-aging, beauty repair, arthritis, sports recovery |
| Blue light | 415-470 | Kill bacteria and reduce inflammation, reduce acne, and inhibit sebum secretion | Acne skin, oily skin, inflammatory skin diseasesGreenlight |
| Greenlight | 520-550 | Relieve stress, improve pigmentation, even out skin tone | People with pigmentation, dull skin, and high-stress levels |
| Yellow light | 570-590 | Strengthen the skin barrier, promote blood circulation, and improve red blood streaks. | People with sensitive skin, skin inflammation, and poor circulation |
Detailed Guide to Different Light Therapy Beds
Low-intensity laser therapy (LLLT): This treatment uses a red cold laser with a wavelength of 633-635 nm. It penetrates the skin to the dermis (a depth of about 2-3 mm), stimulates mitochondria to produce more ATP energy, and accelerates cell repair and regeneration.
Photobiomodulation: Red light achieves the dual effects of anti-inflammatory and tissue repair by regulating inflammatory factors (such as reducing IL-6, and TNF-α) and promoting collagen synthesis.
High safety: non-invasive, non-invasive operation, clinical studies show that the incidence of adverse reactions is less than 2%.
Wide applicability: It can be used alone or in combination with drugs/other phototherapy (such as blue light) to shorten the course of treatment (such as the acne treatment cycle is reduced by 30%-50% compared with traditional methods).
Good tolerance: It is suitable for children, the elderly, and sensitive skin groups, is painless, and does not require a recovery period.
Patients in the recovery period of postoperative wounds (such as laser surgery, or surgical incisions).
Patients with inflammatory skin diseases such as acne and dermatitis.
People with aging skin, pigmentation, and scar hyperplasia.
People with chronic pain or muscle strain (such as arthritis, shoulder and neck pain).
Skin diseases: acne (especially inflammatory papules), postoperative wound healing, herpes zoster neuralgia, eczema.
Anti-aging repair: improve photoaging (fine lines, relaxation), fade pigmentation and acne marks.
Chronic inflammation: relief of local inflammation such as arthritis and tendonitis.
Nerve damage: pain or numbness caused by peripheral neuropathy.
Photodynamic effect: Blue light wavelength (417nm±10nm) can activate endogenous porphyrins in Propionibacterium acnes, produce reactive oxygen species (ROS), destroy the bacterial structure, and kill pathogens.
Regulate sebum secretion: inhibit sebaceous gland cell activity and reduce oil secretion (clinical data show that oil secretion decreases by about 20%-30%).
Anti-inflammatory repair: relieves redness and inflammatory response by reducing inflammatory factors (such as IL-1α, TNF-α) and regulating immune response.
pH regulation: changes the pH value of the skin microenvironment and inhibits bacterial reproduction.
Non-invasive: non-invasive operation, painless, no anesthesia or recovery period required.
Precise antibacterial: the killing rate of Propionibacterium acnes can reach more than 70%, and it has a significant effect on mild to moderate acne.
High safety: no systemic side effects, suitable for people who are intolerant or allergic to antibiotics.
Combined synergy: The efficacy is increased to 35.7% when combined with red light (only 8.3% for blue light alone), and it can be combined with Chinese medicine molding to enhance the efficacy.
Controllable course of treatment: Standardized treatment cycle (4 weeks/12 times), the effect can be quantitatively evaluated.
Patients with mild to moderate acne: mainly inflammatory papules and pustules, and those with oily skin (cysts and nodules have limited effect).
Oily/mixed skin: people with vigorous sebum secretion and prone to acne.
Those with antibiotic intolerance: the preferred option to replace oral antibiotics for the treatment of acne.
Those who need combined treatment: such as complex acne cases with red light, DRr, UGS, or external treatment of traditional Chinese medicine (such as molding).
Mild to moderate acne: inflammatory papules and pustules (especially superficial lesions).
Folliculitis: redness, swelling, and suppuration caused by bacterial hair follicle infection.
Seborrheic dermatitis: local inflammation accompanied by excessive oil secretion.
Postoperative adjuvant: combined with other therapies to promote postoperative repair of acne (such as reducing wound infection).
Selective light absorption: Green light wavelength (520-560 nm, commonly used 525/532 nm) can be preferentially absorbed by hemoglobin and melanin, and can act precisely on blood vessels or pigment target tissues through photothermal effects.
Photobiomodulation: Regulates the sensitivity of skin nerve endings (such as inhibiting TRPV1 channels), reduces pain transmission, promotes lymphatic circulation, and reduces tissue edema.
Vascular regulation: For capillary dilation (such as rosacea), redness is reduced by contracting the smooth muscle of the vascular wall.
High precision: Abnormal retinal blood vessels can be accurately closed in ophthalmic applications (error <50 μm), and surrounding healthy tissues are not damaged during skin treatment.
Low invasiveness: Non-thermal damage mechanism, fast postoperative recovery (skin treatment does not require downtime).
Multi-scenario application: Compatible with ophthalmology, dermat, ology, and pain management, combined with yellow light/red light to enhance the efficacy.
Safety: No ultraviolet radiation, sensitive skin tolerance is better than blue light/red light.
Ophthalmology patients: patients with diabetic retinopathy, macular edema, retinal holes, etc. who need photocoagulation treatment.
Sensitive skin group: patients with rosacea, red blood streaks, postoperative r, redness, or damaged skin barrier.
Chronic pain patients: patients with neuropathic pain, muscle, strain, or postoperative edema.
Pigment abnormalities: epidermal pigmentation (such as freckles) or superficial capillary dilation.
Ophthalmology diseases:
Diabetic retinopathy (photocoagulation to seal leaking blood vessels)
Retinal vein occlusion, macular edema
Skin problems:
Rose acne (erythema stage)
Sensitive skin and redness, and darkening after laser surgery
Superficial pigmentation (combined with Q-switched laser for synergistic effect)
Pain management:
Postherpetic neuralgia
Chronic muscle soreness (such as shoulder and neck strain)
Photobiomodulation: Yellow light with a wavelength of 577-597 nm (commonly 590 nm) penetrates the epidermis, acts on the cell membrane, mitochondrial membrane, and nuclear membrane, triggers photobiostimulation response, promotes cell self-repair and collagen deposition (MMP-1 levels decrease within 24 hours after treatment, and collagen synthesis increases).
Vascular regulation: Targeting the peak of hemoglobin absorption (590 nm), contracting and dilating capillaries, inhibiting vascular nerve hyperreactivity, and reducing redness and burning sensation.
Anti-inflammatory and barrier repair: Reduce the activity of inflammatory factors, reduce tissue edema, and enhance skin barrier function (such as promoting sebum membrane reconstruction).
High safety: low-energy cold light source (energy density 30 mW/cm²), non-invasive and painless, excellent tolerance for sensitive skin (adverse reaction rate <2%).
Quick relief: A single treatment of 15 minutes can relieve acute inflammation (such as sunburn redness and swelling), and clinical studies have shown that MMP-1 levels significantly decrease within 24 hours.
Lasting effect: When combined with cold spray, moisturizing mas, k, and other therapies, the total effective rate can reach 81.25% (53.13% in the control group) after 8 weeks, and the recurrence rate is reduced to 13.64% (45.45% in the control group).
Versatility: compatible with postoperative repair (such as anti-blackening after laser), anti-aging (reducing wrinkles), and inflammation control, and can be synergistic with other phototherapy (red light) or topical therapy.
Sensitive skin group: manifested as redness, burning, stinging, or intolerance to cosmetics (such as abuse of skin care products, or excessive barrier damage after medical beauty).
Vascular hyperreactive skin: patients with rosacea (erythema stage) and capillary dilation (red blood).
Those who need postoperative repair: people who need to reduce inflammation and promote healing after medical beauty such as laser and skin resurfacing.
Chronic dermatitis patients: inflammatory states accompanied by redness, swelling, and desquamation such as facial allergic dermatitis and contact dermatitis.
Inflammatory skin diseases:
Facial allergic dermatitis (studies show that the effective rate is 71.87% after 4 weeks of treatment)
Rose acne (erythema stage), seborrheic dermatitis
Vascular abnormalities:
Capillary dilation (red blood streaks), skin flushing
Postoperative repair:
Blackening after laser surgery, skin barrier damage
Sunburn (accelerates the disappearance of redness and swelling, reduces pigmentation)
Anti-aging assistance:
Fine lines improvement (by inhibiting MMP-1 and promoting collagen deposition)
