The Science and Effectiveness of Cold Laser Facial Therapies

The Science

SkinPhD's Photo Bio-Stimulation is low level laser therapy otherwise known as cold laser therapy. Cold lasers supply energy to the body in the form of non-thermal photons of light. Light is transmitted through the skin’s layers (the dermis, epidermis, and the subcutaneous tissue or tissue fat under the skin) at all wavelengths in the visible range. However, light waves in the near infrared ranges penetrate the deepest of all light waves in the visible spectrum. Photo bio-stimulation is the process where a chain of chemical reaction is triggered by exposure to light. Primary photo-acceptors (which are activated by light) are located in the mitochondria and can convert light energy to electro-chemical energy. It is this energy that heals, repairs, builds collagen, increases cell turnover, and oxygenates the blood, and gives an overall appearance of healthy skin.

It is a scientific fact that light transmitted to the blood in this way has positive effects throughout the entire body, supplying vital oxygen and energy to every cell, increasing cell turnover, and improving collagen and elasticity.

What should you expect during our Photo Bio-Stimulation Facial?

The most noticeable sensation is the touch of the probe head of the device as it comes into contact with the skin. Some have noted that they are able to sense a slight feeling of warmth but most notice nothing at all. The key to skin health with our photo bio stimulation facial is to schedule a treatment every month or at least every other month.

Credibility and Clinical Studies

Our engineers worked on the Russian space program; they are among the most prominent physicists and engineers in the world.  Over 2500 published articles on light therapy exist with over 1200 references.  Over 170 randomized, double blind studies were conducted.  Positive studies use appropriate wavelength, energy density, dose, treatment technique and schedule of treatments.

How does our cold laser work?

The TerraQuant is designed with three specific radiances built into a cluster. The Standard probe combines the following wavelengths and light sources:

∞905nm super-pulsed laser
∞875nm non-coherent IREDs
∞660NM non-coherent LED

These wavelengths combine the most effective infrared wavelengths with a red light LED. The resulting photochemical reaction from these modalities produce: 1) an increase in the cellular metabolism rate that expedites cell repair and the stimulation of the immune, lymphatic and vascular systems, 2) an increase in collagen and elasticity in the skin, 3) an increase in oxygen flow and energy throughout the body, 4) a decrease in bacteria, 4) an improvement in tone and texture, and 5) a youthful glow which all lead to beautiful and healthy skin!
