Cold Lasers & Hot Lasers, What’s the Difference?

Hot Lasers can cut, burn and vaporize tissue. They are precise tools that are often used in surgery in place of standard surgical tools (scalpels), because they do less damage to normal tissues. Consequently, patients usually have less pain, bleeding, swelling, and scarring. With hot laser therapy, operations are usually shorter and recovery is faster. Hot lasers are also use in dentistry, and in tattoo and hair removal.

Cold Lasers are therapeutic lasers that produce an insignificant amount of heat and are extremely safe for use by home users and professionals. They biostimulate cells to increase cellular growth and regenerative activity, while simultaneously deactivating 7 or the 9 enzymes that cause inflammation by up to 70%. Cold Lasers  increase cellular energy by delivering photons, which are converted by the Mitochondria inside the cells into Adenosine Triphosphate  (ATP). This is the preferred fuel source of all cells in the human body.

Cold Lasers are commonly used for pain relief, skin and burn healing and facial rejuvenation. Cold Lasers are also commonly used in Laser acupuncture or Acu-Light Therapy, which is an off-shoot of acupuncture and is particularly well-suited for the treatment of carpal tunnel syndrome (CTS), back, neck and shoulder conditions and smoking cessation and weight management. There are protocols for treating over 4000 symptoms and conditions with acupuncture. While Acu-Light Therapy uses the same points as acupunctue, there are no needles involved, so it is completely painless and non-invasive. Acu-Light Therapy can be self administered if sufficient information is provided on how to precisely locate the correct points for a given condition. Many good books exist on this subject. Acupuncture has very few contraindications, and the side effects are few.

My favorite cold lasers are also known as therapeutic lasers. The most versatile cold laser is called the Scalar Wave Laser (SWL). The main unit utilizes a cluster of 16 lasers and a total of 36 diodes to cover 2.5” diameter surface area. It's an ultra-portable hand-held laser that is powered by a rechargable lithium ion battery or power cord. The unit has a built in frequency generator and scalar wave generator, which is capable of generating any combination of frequencies desired from 0-40,000 Hz. This system comes with preset frequency modes and 24 empty slots, which will allow user programming of an infinite combination of frequency combinations. It has three optional concentrated laser probes available that are ideal for using to treat individual acupoints, auricular points, trigger points and myofacial points. The probes are sturdy and well built, so that they can also be used as a laser massage tool over the key points and muscles.  For more information on cold lasers visit:
