Can barely get out of bed in the morning because of pain? Does every movement during the day remind you something is wrong? The Personal Laser L400 brings clinical-level soft-laser therapy into your home – medical-clinic effectiveness in a pocket-sized device Why choose the Personal Laser L400? 400 mW true laser power Not LED, not prism-scattered — this is a real Class 3B diode laser. The continuous 400 mW output reaches 3–8 cm deep into tissues, reaching areas that lower-power devices cannot. Done in minutes — not half an hour It takes only 10 seconds to deliver 4 Joules of energy. A full knee treatment can be completed in 3–5 minutes — whereas other devices may require 30–40 minutes. Precise, targeted therapy The 1 cm² beam area allows precise treatment of individual pain points, tendons and nerves — you can aim exactly where it hurts without spreading the energy unnecessarily. Pocket-sized, use at home Only 42 grams, 76 mm long — almost smaller than a ballpoint pen. Rechargeable battery provides 2 hours of continuous treatment. You can use it at the office or while traveling. What to use it for? Stiff in the morning,does your knee hurt during the day? Sound familiar? You need 10 minutes of moving your knee in the morning before you can go down the stairs. Every squat or stair reminds you. Knee osteoarthritis and joint inflammation are the most common causes — and unfortunately may worsen over time. Research suggests soft-laser therapy can help reduce knee pain. A meta-analysis of 22 trials (BMJ Open, 2019) found that 785–860 nm wavelength lasers at 4–8 J/point significantly reduced pain compared with placebo. The Personal Laser L400 operates within this therapeutic window. Treatment suggestion: Treat around the knee in 6–8 points, 30–40 seconds per point (3–4 beeps). Daily in the first week, then 2–3 times weekly. Detailed knee pain treatment guide → By afternoon can you barely straighten your lower back? Sound familiar? After getting up from your office chair your lower back protests. Herniated discs, degeneration and muscle overload may all contribute. The 808 nm wavelength penetrates deeply into tissues, so energy can reach deeper spinal structures. Photobiomodulation may help reduce inflammation and support tissue regeneration in the muscles and joints around the spine. Treatment suggestion: Treat along the painful spinal segment in 4–6 points, 30–40 seconds per point. Herniated disc treatment guide → Does the first step out of bed shoot pain into your heel? Sound familiar? You step out of bed and sharp pain stabs your heel. Plantar fasciitis and heel spurs cause daily suffering for millions. A 2022 systematic review and meta-analysis (BMJ Open) confirmed soft-laser therapy can significantly reduce pain and functional impairment in lower-extremity tendinopathies and plantar fasciitis, both at end of treatment and 4–12 weeks later. Treatment suggestion: Treat the heel and plantar fascia in 4–6 points. Heel pain treatment guide → Pulled again? Another two weeks off? Sound familiar? You train hard — then one wrong move and two weeks of rest again. Muscle strains, tendonitis, ligament sprains are athletes’ common enemies. Research on photobiomodulation suggests it may support tissue regeneration, reduce inflammation and boost mitochondrial energy production. The 400 mW power quickly delivers energy to injured tissue — the treatment can be added before or after daily training. Treatment suggestion: Directly on the injured area in 3–5 points, 30–40 seconds per point. For acute injuries, it can be used twice daily in the first 48 hours. Sports injury treatment guide → Herpes again?Always at the worst time? Sound familiar? Stress, sun exposure, a cold — and the unpleasant tingling appears on your lip. Herpes (HSV) affects much of the population and is often recurrent. A 2022 two-year randomized controlled trial showed photobiomodulation can significantly reduce the recurrence frequency and severity of herpes labialis compared with placebo. The treatment was side-effect free. Treatment suggestion: Apply direct contact along the tingling area for 30 seconds, covering each point. For prevention: treat the previous outbreak site 1–2 times weekly. Herpes laser treatment guide → Numbness, stabbing in your hand? Pain waking you at night? Sound familiar? Your wrist goes numb at the mouse, you wake up at night from stabbing pain in your fingers. Carpal tunnel syndrome and peripheral neuropathy are increasingly common among office workers and people with diabetes. A systematic review found soft-laser therapy may be beneficial in reducing painful diabetic peripheral neuropathy and improving nerve conduction. The 1 cm² beam area is especially suitable for precise, targeted treatment of nerve pathways. Treatment suggestion: Treat along the nerve path in 3–5 points. Carpal tunnel treatment guide → Is your dog slow to get up? Is your cat limping? Sound familiar? Your aging dog struggles to stand in the morning, your cat is limping and you feel helpless. Soft-laser therapy can also be used on animals — photobiomodulation similarly supports tissue regeneration and pain relief. The 400 mW power delivers sufficient energy even to joints of larger animals. The treatment is stress-free — most animals visibly relax during treatment. Important: Never direct the laser beam into an animal's eyes! Laser therapy for animals → How to use? It's that simple: 1 Put on the protective goggles The device is a Class 3B laser — wearing the supplied protective goggles during treatment is mandatory. Make sure no one else looks into the laser beam. 2 Switch on and place on the skin Press the power button — the green LED indicates active status. Place the treatment head directly on the skin at the painful spot. For open wounds keep about 5 cm distance. 3 Treat each point for 30–40 seconds The device beeps every 10 seconds — this indicates that 4 Joules of energy have been delivered. Typically 2–4 beeps (8–16 Joules) per point is recommended. Treat larger areas point by point. 4 Repeat regularly During the first week treat the affected area daily. From the second week reduce to 2–3 times weekly, then for maintenance 1–2 times weekly is sufficient. The device automatically switches off after 5 minutes. What's in the package?

Buy accessories here: Soft-laser accessories → Frequently asked questions Is protective eyewear required? Yes, mandatory! The Personal Laser L400 belongs to laser class 3B, therefore wearing protective goggles during treatment is mandatory. A professional protective laser goggle is included and complies with safety regulations. Directing the laser beam into the eyes is forbidden — it can cause permanent eye damage! How long is one treatment? Treating a single point takes only 10–40 seconds. A full treatment (e.g. knee — 6–8 points) usually takes 3–5 minutes. This is significantly shorter than lower-power devices, where the same treatment can require 20–40 minutes. The device automatically switches off after 5 minutes — preventing overuse. Does the laser treatment hurt? No, soft-laser treatment is painless. The 808 nm infrared light is not visible to the eye, but a slight warming sensation may occur on the treated area. This is a normal reaction and indicates tissue energy absorption. How many times a day can I use the device? For chronic issues, one treatment daily is recommended in the first week. From the second–third week reduce to 2–3 times weekly, then from the fourth week reduce to 1–2 times weekly. For acute complaints 1–2 treatments per day may be used. A treatment point is recommended 30–40 seconds (3–4 beeps). How is the Personal Laser L400 better than the Safe Laser 500 or B-Cure? The Personal Laser L400 is a true 400 mW continuous-output diode laser, while B-Cure and Safe Laser use prism-scattering technology that results in lower energy density. The L400 achieves the same energy dose in a much shorter time: delivering 5 Joules takes 12.5 seconds versus 3 minutes for Safe Laser and 5–8 minutes for B-Cure. It also allows deeper tissue penetration and more precise, targeted treatment. Can I use it on animals? Yes, soft-laser therapy can be applied to animals. The Personal Laser L400 can effectively aid musculoskeletal complaints and wound healing in pets. It is important never to point the laser into the animal's eyes.

Personal-Laser L400 ⭐ – Class 3B home soft-laser at an affordable price. The 400 mW focused diode laser delivers 5 Joules to tissues every 12.5 seconds — an excellent entry-level choice as adjunct therapy for joint pain, minor injuries and superficial inflammations. Energy-Laser L500 Pro – If you want slightly faster treatments. The 500 mW power reduces treatment time by about 25% compared to the Personal-Laser L400. Effective as adjunct therapy for deeper joint or spinal problems, in a compact size. Safe Laser 500 Infra – The main market competitor. Prism-scattered beam, Class 1 device that can be used without protective goggles. However, due to the scattered beam the actual power density is much lower: to reach the same therapeutic dose requires about 5–6× more treatment time than the Personal-Laser L400. The two-class difference (1 vs. 3B) is also felt in therapeutic efficacy. Nevertheless, the Safe Laser 500 is positioned at a higher price point than the Personal-Laser L400 — so the value-for-money ratio clearly favors the Personal-Laser L400. When NOT to use the device?
