Personal Laser L400 softlaser (LLLT)

A Personal Laser L400 is a modern, medically certified medical device that operates 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.

Application Areas

The Personal Laser L400 is widely used to treat various musculoskeletal problems and painful conditions.

Common application areas of the softlaser include, without limitation:

• Musculoskeletal problems: joint inflammation, tendon inflammation, 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 nerve palsy, facial paralysis and gum inflammation.

The beneficial effects of 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 actual healing processes.

It is excellently suitable for the most common musculoskeletal complaints such as chronic back pain, neck pain and joint inflammations. It assists in the treatment of knee joint wear, shoulder problems, and temporomandibular joint inflammation. Additionally, it is ideal for promoting wound healing (for example scars, ulcers, stretch marks, acne) and postoperative rehabilitation.

Simple and Safe Use

The Personal Laser L400 is designed to be user-friendly. The device is compact, measuring only 76 mm long and 27 mm in diameter, with a weight of just 42 grams. Thanks to its ergonomic design, it is easy to handle and accurately position on the treatment area.

Safe use 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 informs about the operating status. Green light indicates active treatment, yellow shows standby, and red warns of possible errors.

The device operates with a rechargeable Li-Ion battery, which fully charged provides 2 hours of continuous treatment. Charging is done through a simple USB connection and takes only 1.5 hours. The battery charge level is also shown on the LED display.

Treatment Protocol and Dosage

For effective treatment, following the proper protocol is important. For chronic problems, one treatment daily is recommended in the first week, which can be reduced to 2-3 times per week in the second to third weeks, and then 1-2 times per week from the fourth week.

For a treatment point, usually 3-4 beeps (30-40 seconds) of treatment time is recommended, delivering 12-16 joules of energy to the tissues. The device emits a beep every 10 seconds, indicating when to change position. This helps avoid excessive local warming and ensures optimal energy delivery.

Different areas require different treatment times:

• Wounds and skin surfaces: 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. In case of open wounds, keep the device about 5 cm away. For larger areas, proceed point by point, treating each point for the recommended time.

Quality and Warranty

The Personal Laser L400 is manufactured according to the strict EU medical device regulations. The device has CE certification (CE 2274) and complies with the ISO 13485:2016 quality management system requirements.

The device is covered by a 3-year warranty. The laser diode is designed for 10,000 operating hours, ensuring years of trouble-free operation under average use.

Safety Information and Precautions

Although the device is designed for home use, it is important to follow some basic safety precautions. Never direct the laser light into or near the eyes. Do not use over the abdomen during pregnancy. Treatment of cancerous areas is also contraindicated.

Consult a doctor or healthcare professional before use, especially if you have epilepsy, bleeding disorders, or other chronic diseases. Always follow the recommended protocol and do not exceed the suggested treatment times.

Scientific Background and Efficiency

The therapeutic application of laser light has a history of several decades. Numerous clinical studies have proven its effectiveness in treating various musculoskeletal problems. The 808 nm wavelength is particularly suitable for treating deeper tissues due to its optimal penetration depth.

The 400 mW power delivered by the Personal Laser L400 is an ideal compromise between efficiency and safety. It provides enough energy to induce therapeutic effects while not causing undesired side effects when used properly.

Maintenance and Hygiene

The device requires minimal maintenance. Clean the laser optics after each use with a 70% alcohol solution. Ensure the device is turned off during lens cleaning. The housing can be wiped with a slightly damp cloth or disinfectant wipe.

For hygienic use, the treatment head must be disinfected after each patient. Using a transparent film can be a practical solution to prevent direct skin contact.

Comparison

The Personal Laser L400 offers several advantages compared to Safelaser 500 or B-Cure devices:

Higher laser class: The Personal Laser L400 belongs to laser class 3, which means higher performance and effectiveness compared to class 1 devices like B-Cure or Safelaser 500. Although class 3 lasers require protective glasses, the increased power allows faster and more efficient treatment.

Higher power and shorter treatment time: The Personal Laser L400 emits continuous laser light at 400 mW. Safelaser 500 and B-Cure use prisms and thus have lower power.
Due to the higher power, the L400 delivers the required energy to tissues faster. It provides both significantly shorter treatment time and higher treatment efficacy.
For example, delivering 5 joules of energy takes only 12.5 seconds with the Personal Laser L400, while B-Cure requires 5-8 minutes and Safelaser 500 takes 2-3 minutes.

Deeper tissue penetration: Due to higher energy density, the Personal Laser L400’s laser beam penetrates deeper into tissues. This enables more effective treatment of larger joints, cartilage and ligaments.

More precise treatment: The L400 laser beam covers 1 cm², which is smaller than B-Cure (4.5 cm²) and Safelaser 150 (2.5 cm²) beam areas. The smaller beam diameter allows more targeted treatment, especially on smaller areas or specific points like trigger points, nerve injuries or polyneuropathy.

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