Light Therapy

 Light therapy consists of exposure to daylight or to specific wavelengths of light using lasers, 

light-emitting diodes,  very bright, full-spectrum light. 

Light Therapy

history behind light therapy

 The year 1988 was the pivotal year for LEDs (Light Emitting Diodes), when Professor Harry Whelan and his team at the Space Medicine Laboratory of the National Aeronautic and Space Administration (NASA) developed the first of a new generation of LEDs, the so-called NASA LED.  

How does it work?

 Photons are discrete particles of pure light energy without mass. The first law of photobiology states that without absorption, there can be no reaction, so the incident photon must be absorbed by the target cells for any reaction to occur. When a photon is absorbed by a cell, it passes on its energy to the cell. The degree of the photon density determines what sort of energy transfer occurs.

Red light will stimulate the growth of collagen. Collagen is an essential protein that is used to repair damaged tissues and to repair the old tissues. It can remove fine lines and shrink pores.  promotes wound healing and tissue repair. improves hair growth in people with androgenic alopecia help for the short-term treatment of carpal tunnel syndrome stimulates healing of slow-healing wounds, like diabetic foot ulcers and can reduce psoriasis lesions

Blue light can help a host of skin disorders.   It can be used to improve skin texture and reduce sebaceous hyperplasia, or enlarged oil glands.  It can help with removing sun spots, acne, and even scars that were originally caused by acne.  Bacteria in acne contains Porphyrins; because of the high affinity with wavelength, the blue light is able to kill Porphyrins. In addition, the blue light has calming action which is very effective for hypersensitivity.

  The green light can balance the color pigment, and reduce fine lines, improve ageing skin, speed up the healing process of the wound, lightening the skin.  Nitrogen is Green, which is the largest component of the atmosphere; it builds muscles, bones and other tissue cells.  Green is considered useful for promoting general healing, restoration and internal balance.

 It can improve the exchange of oxygen in the cells, and to the skin cells to replenish their energy.  It is considered to be an ideal therapy for sensitive skin, as its therapy is calming and soothing. Yellow/Amber light therapy helps reduce the appearance of redness, swelling and inflammation on the surface. This color of light is beneficial for rosacea and the treatment of burns.

It is predominately used for its antibacterial benefits and therefore used in acne treatment.  It combines red light and blue light, which has two photo therapies effective.   Purple light is absorbed by a molecule called porphyrin. Acne bacteria contain an abundant amounts of porphyrin. The absorption of Purple light by porphyrin creates singlet oxygen (free radicals) which are released into the bacteria thus killing the bacteria. Purple is also anti-inflammatory.

  It can penetrate the skin deeply to accelerate the tissue metabolism, decomposition color spots, improve the appearance of fine lines and ageing skin.  Light therapy is a way to treat seasonal affective disorder (SAD) and certain other conditions by exposure to artificial light. SAD is a type of depression that occurs at a certain time each year, usually in the fall or winter.
