Personal Laser L400 softlaser (LLLT)

The Personal Laser L400 is a modern, medically certified medical device operating on the principle of low-level laser therapy (LLLT) and photobiomodulation (PBM). The device uses an 808 nm infrared laser light with 400 mW power, effectively relieving pain and accelerating tissue regeneration.

Applications

The Personal Laser L400 is widely used for treating various musculoskeletal problems and painful conditions.

Typical areas of use for the softlaser include, but are not limited to:

• Musculoskeletal problems: arthritis, tendinitis, bursitis, muscle strains, and joint pain.
• Skin problems: acne, ulcers, scars, and stretch marks.
• ENT problems: tinnitus and ear canal inflammation.
• Dental problems: jaw inflammation, facial neuralgia, facial paralysis, and gingivitis.

The beneficial effects of the laser light are scientifically proven. During treatment, the light energy penetrating the tissues stimulates cell function, improves blood circulation, and reduces inflammatory processes. Regular use not only provides symptomatic relief but also promotes genuine healing processes.

It is excellent for the most common musculoskeletal complaints such as chronic back pain, neck pain, and arthritis. It supports treatment of knee joint wear, shoulder problems, and jaw joint inflammation. It is also highly effective in promoting wound healing (e.g., scars, ulcers, stretch marks, acne) and postoperative rehabilitation.

Simple and safe use

The Personal Laser L400 is designed with user-friendliness in mind. The device is compact, measuring just 76 mm in length and 27 mm in diameter, with a weight of only 42 grams. Its ergonomic design allows easy handling and precise positioning on the treatment area.

Safety is ensured by multiple built-in protections. The device automatically switches off after 5 minutes of use or in case of overheating. The built-in LED display continuously indicates operational status. Green light means active treatment, yellow indicates standby, and red warns of any errors.

The device runs on a rechargeable Li-Ion battery, providing up to 2 hours of continuous treatment when fully charged. Charging is via a simple USB connector and takes only 1.5 hours. The battery charge level is also shown on the LED display.

Treatment protocol and dosage

Effective treatment requires following the proper protocol. For chronic issues, daily treatment is recommended during the first week, then 2-3 times per week in weeks two and three, then 1-2 times per week from the fourth week onward.

For one treatment point, a typical duration is 3-4 beeps (30-40 seconds), delivering 12-16 joules of energy to the tissues. The device beeps every 10 seconds to indicate when to reposition. This helps avoid excessive local heating and ensures optimal energy delivery.

Treatment times vary by area:

• Wounds and skin areas: 2-5 joule/cm²
• Tendons, joints, muscles: 5-10 joule/cm²
• Pain points: 10-150 joule or until pain relief

During treatment, the device should be placed directly on the skin. For open wounds, maintain approx. 5 cm distance. For larger areas, treat point by point, each for the recommended duration.

Quality and warranty

The Personal Laser L400 complies with the EU's stringent medical device regulations. The device holds CE certification (CE 2274) and meets ISO 13485:2016 quality management system standards.

The device comes with a 3-year warranty. Its laser diode is rated for 10,000 operating hours, ensuring several years of trouble-free use with average usage.

Safety information and precautions

Though designed for home use, basic safety rules must be followed. Never direct the laser beam into eyes or surrounding areas. Do not use on the abdomen during pregnancy. Treating cancerous areas is contraindicated.

Consult a physician or healthcare professional before use, especially if you have epilepsy, blood clotting disorders, or chronic diseases. Always adhere to the recommended protocol and never exceed suggested treatment times.

Scientific background and effectiveness

Laser therapy has decades of clinical evidence supporting its effectiveness in managing musculoskeletal problems. The 808 nm wavelength is especially suitable for deeper tissue treatment due to its optimal penetration.

The 400 mW power output of the Personal Laser L400 strikes an ideal balance between efficacy and safety. It delivers sufficient energy for therapeutic effect without unintended side effects when used properly.

Maintenance and hygiene

The device requires minimal maintenance. After each use, clean the laser optics with 70% alcohol solution. Ensure the device is off while cleaning the lens. Wipe the housing with a slightly damp cloth or disinfectant wipe.

For hygiene, disinfect the treatment head after each patient. Using a transparent foil covering to prevent direct skin contact is recommended.

Comparison

The Personal Laser L400 offers some advantages over the Safelaser 500 and B-Cure devices:

Higher laser class: The Personal Laser L400 is a class 3 laser device, meaning higher power and effectiveness than class 1 devices like the B-Cure or Safelaser 500. Although class 3 lasers require protective goggles, their increased power enables faster and more effective treatment.

Higher performance and shorter treatment time: The Personal Laser L400 outputs a continuous 400 mW laser beam. Both Safelaser 500 and B-Cure use prism technology and have lower power. The L400 delivers the required energy into tissues faster, resulting in significantly shorter treatment durations with higher effectiveness. For example, delivering 5 joules takes only 12.5 seconds with the Personal Laser L400, compared to 5–8 minutes for B-Cure and 2–3 minutes for Safelaser 500.

Deeper tissue penetration: Due to higher energy density, the laser beam of the Personal Laser L400 penetrates more deeply into tissues, allowing more effective treatment of large joints, cartilage, and ligaments.

More precise treatment: The L400 laser beam covers 1 cm² area, smaller than B-Cure's 4.5 cm² or Safelaser 150's 2.5 cm² beam. This smaller beam diameter enables more targeted treatment, especially on small areas or specific points such as trigger points, nerve injuries, or polyneuropathy.

Overall, the Personal Laser L400 can provide more efficient and faster treatment than the other two devices, especially for deeper tissue problems.
