Safe and effective usage guidelines and precautions
With the increasing popularity of home-use red and blue light therapy devices, many people hope to use them to assist in treating minor wounds at home. Correct use is key.
Applicable Wound Types (Heimgebrauch):
Small abrasions and cuts (after bleeding has stopped)
First-degree or superficial second-degree burns
Late recovery period for healed wounds with scarring
Pimples with broken skin (pay attention to device cleanliness)
Operating Steps and Suggestions:
Cleanliness First: Always clean and disinfect the wound according to standard wound care procedures.
Geräteauswahl: Choose a device with a wavelength of 630-660nm (Rotlicht) or 800-850nm (Leinesblattlicht), and ensure the output power is within a safe range (usually low for home-use devices).
Irradiation Method: Maintain an appropriate distance between the device and the skin (normalerweise 5-15 cm according to the instructions), directly irradiating the wound area.
Time and Frequency: It is recommended to irradiate for 5-10 Minuten jedes Mal, 1-2 times a day. More is not necessarily better; follow the principle of “low dose, high frequency.”
Observe the response: The wound should feel comfortable after treatment. Discontinue use immediately if increased redness, Schwellung, or discomfort occurs.
Important Warning: Do not use on undiagnosed infected wounds, malignant tumor wounds, active bleeding wounds, or severe third-degree burns. Chronic, complex wounds (such as severe diabetic ulcers) must be used under the guidance of a physician.
Appendix: FAQ (Häufig gestellte Fragen)
Q1: Is red and blue light therapy really effective for treating wounds? Is there scientific evidence?
A: Ja, it is effective. Numerous clinical studies published in authoritative journals such as Wound Repair and Regeneration Und Laser in Chirurgie und Medizin support its positive effects on various acute and chronic wounds. It has been approved by the FDA for the treatment of muscle and joint pain and some wound care.
Q2: Was ist der Unterschied zwischen rotem Licht und nahezu Infrarotlicht? Which is better for wounds?
A: Rotlicht (630-700nm) penetrates shallower, effectively targeting the skin’s surface and collagen synthesis; Leinesblattlicht (800-900nm) penetrates deeper, reaching subcutaneous tissue and muscles, providing better relief for deep inflammation and pain. Many devices combine both wavelengths for a more comprehensive effect.
Q3: What are the risks or side effects of using red and blue light therapy to treat wounds?
A: Side effects are minimal when used correctly. Possible risks include: overuse leading to dry or red skin; direct eye contact with the light source may cause discomfort or damage (wearing protective goggles is recommended); use on unsuitable wounds (such as malignant wounds) may delay treatment.
Q4: At what stage can red and blue light therapy be started on a wound?
A: It is recommended to start using it during the inflammatory and proliferative phases after the acute bleeding phase for the most significant results. This can begin once the wound is clean and there is no active bleeding. Use during the later remodeling phase of healing also helps improve scarring.
F5: Are home-use and medical-use devices equally effective?
A: Medical devices typically have higher power, more precise parameters, and clinically validated protocols, resulting in more significant effects. Home-use devices, as daily care and auxiliary methods, are convenient and easy to use, and effective for superficial and minor wounds. Jedoch, they cannot replace professional medical treatment for severe or chronic wounds.
F6: How long does one irradiation session take? Wie lange dauert es, bis Ergebnisse sichtbar sind??
A: A single irradiation session usually lasts 5-15 Minuten, 1-2 times daily. Results vary depending on the type and severity of the wound. Chronic wounds may require several weeks to observe significant improvement, while minor abrasions may show accelerated healing within days.
