In the world of cosmetic lasers, technology has finally caught up with people’s expectations. Laser therapy is one of the fastest expanding and most exciting fields in the cosmetic arena. In the past, those seeking to turn back the hands of time had to turn to Botox / Restylane injections, harmful chemicals or expensive medical procedures. But today, more and more are turning to the rejuvenating power of light therapy.
To understand how lasers work, we first have to understand what a laser is. “Laser” is an acronym for Light Amplification by Stimulated Emission of Radiation. The idea of a laser can be traced back to Albert Einstein’s theoretical work in the beginning of the 20th century. He predicted that it would be possible to stimulate electrons to emit light of a specific wavelength. Laser light is therefore light, but a very specific type of light.
For us, the most natural form of healing light is the sun. The beneficial light energy from the sun is a primary source of cellular energy for most life forms on earth. Sunlight is non-coherent light that encompasses light ranging from the ultraviolet range to the infrared range and everything in between (visible light range). The light energy emitted by laser devices is coherent monochrome light oscillating in harmony that falls into specific wavelengths already found in the spectrum of sunlight, but does not include skin-damaging ultraviolet A and B wavelengths. The different laser wavelengths dictate the depth of penetration through specific substances (such as human tissue). This form of light provides better penetration of the top layers of the skin and can stimulate the low layers of the skin where problems normally form. With cosmetic lasers the light energy is absorbed into the skin where the cells use it to product ATP or cellular energy. The light also helps stimulate collagen, blood flow and other healing regenerative mechanisms.
Low-level laser therapy has come a long way since Einstein’s theories, and devices that emit low-level laser light in a therapeutic fashion have left the hospital and doctor’s office and hit the shelves of stores. Skepticism still remains however, on the effectiveness and safety of such laser devices for cosmetic use. Let’s examine some basic essentials about low-level lasers and debunk some misconceptions.
Low-Level Lasers are Safe
Low-level lasers have been used as a therapeutic modality in the international medical field for over 30 years. In the 30+ years of low-level laser usage, no side effects or contraindications are known or have ever been reported.
Unlike high powered surgical lasers, low-level lasers are safe and painless. Most devices can be used on all skin types and cause no heat or sensation. Although the technology is the same, the safety standards and compliances that devices must adhere to make personal lasers less powerful and much gentler than lasers found in spas and skin care centers.
Naturally Stimulate the Skin
The true key to the benefits of laser light is found in its effects in the cell. And being that the human body is made up of approximately FIVE TRILLION cells, it is easy to understand how poor performance on a cellular level can affect the body. Laser light has been shown to affect the body on a biological and cellular level through more effective and faster cell renewal, absorption of vital nutrients, increased collagen production, stimulation of the mitochondria (cellular healing) and ATP (energy) production. In layman terms, low-level lasers feed cells energy and allow them to regenerate in a healthy fashion.
Effectiveness of Low-Level Lasers
Studies now confirm these biological and cellular processes. A recent study at the Department of Biomedical Engineering, Shanghai Jiao Tong University, Shanghai, China shows that “laser treatments led to marked improvements in dermal layer thickness and collagen fiber density”. Collagen is a key to anti-aging treatments. Collagen is a protein structure that is responsible for skin strength and elasticity, and its degradation leads to wrinkles that accompany aging.
Another study at the Laser and Skin Surgery Center of New York came to the conclusion that “nonablative (low-level laser) procedures are effective in the treatment of photoaging and acne scarring. As technology in nonablative therapies continues to evolve, future laser and light sources may yield even more favorable results.”
What to Expect
Doctors, professionals and users all agree that laser light can be beneficial for cosmetic use, but what kind of results can you expect?
First off, being that personal low-level lasers have to adhere to power restrictions to make them safe for home use, you can’t expect the same results as with professional treatments. A number of spas now sell personal low-level laser devices as a compliment to spa treatments like photofacials, Thermage and other laser services.
You also have to take into account that for improvements to occur, daily use is required (5-15 minutes, 2 times daily). The effects of such personal lasers are accumulative, meaning that the more often and consistent you are with treatments, the better the results. As one satisfied user of a personal cosmetic laser commented, “The improvement around my eyes was the first thing I noticed. I also have scar tissue that has vanished. I am extremely happy with my laser. Of course, if you don’t want to find the time to use it twice daily, the results won’t be as great. I am 61 years young and my skin looks great. “
As more people look to defy the aging process and begin to stray away from costly and potentially harmful methods, personal low-level lasers will continue to grow in popularity. Efficacy and safety of these lasers have been confirmed, but it’s still no magic pill. In the end, one has to expect realistic improvements with such devices and realize that aging is a part of life that there will never be a cure for. But at least now with emerging Low Level Laser technologies you can really age gracefully and with style.
Starlite is a personal use cosmetic laser recently released into the US market. Developed by highly proficient engineers (experienced with NASA and Medical Data Laboratory) and manufactured from only the highest quality components from Japan, US and Taiwan, this new home laser is the pinnacle of skin care devises. Starlite is currently the only product available to combine medical grade laser technology, a pulsed infrared LED as well as an optical lense for maximum efficacy. The specialized light produced by Starlite is absorbed deep into the skin to aid in the production of collagen and ATP (energy). This makes the small handheld unit excellent for wrinkles, fine lines and blemishes.
