What is used for surgeries is known as a high-powered surgical laser. What is used for cosmetic purposes is known as a low-level laser or soft light laser. Industry standards dictate that the lasers used for anti-aging treatment be painless and perfectly safe. They have to be suitable for all skin types; the patient should not experience any uncomfortable sensation or excess heat.

Laser works on the principle of light, the same way the sun does. While sunlight emits non-coherent light, the laser device gives out coherent monochrome light. The sun has a spectrum ranging from ultraviolet to infrared, with a visible light range in between. UV rays can cause great harm to the skin. In contrast, the laser device also provides specific wavelengths of light that oscillate in harmony, but omits ultraviolet A and ultraviolet B wavelengths. Naturally, all the light rays coming from the laser device are beneficial to your skin.

The advantage to these varied wavelengths is their capacity to go deep into the dermal layers of the skin. Even the cells at the bottom get stimulated into action then. The cells release their stored energy from mitochondria, or what is known in scientific circles as ATP (Adenosine tri-phosphate). Considering that your body is said to possess around five trillion cells, you can well imagine the total energy that is generated. The damaged cells get repaired as collagen production is stimulated; even new cells are produced at a much faster rate than before. The cells are able to get access to essential nutrients much more easily because the circulatory system or transport system is forced to function more effectively. To put it in very simple terms, laser therapy is responsible for energizing the cells and prompting rejuvenation and regeneration.

This is not mere heresy; it is fact. The Laser and Skin Surgery Center at New York tested low-level laser therapy on scars left behind by acne, and photo aging. This non-ablative procedure threw up excellent results. Even Chinese researchers have observed that laser therapy enhances the density of depleted collagen fibers, as well as increases the thickness of dermal layers. Thus, lasers do improve cellular and biological processes within the human body.

Now, laser treatments are offered at skin care clinics or spas, but you can go in for a personal laser device too. There are certain differences between a professional laser device and a personal laser device, however. Your personal device has to follow much more stringent safety regulations, especially where power is concerned. Nobody wants you to get into any kind of danger or problem. Pamper yourself twice daily, anywhere between 5 and 15 minutes each time. The key to your youthful appearance is consistency and regularity.

Unlike in professional centers, your personal laser device will afford slower results; you need to be patient. Do not overdo it just to see quick results. If you are not confident, however, it is advisable to continue with an expert at treatment centers.
