Contribution of Light Therapy to Acne Treatment

The treatment of acne vulgaris is advancing rapidly thanks to laser therapies and high-intensity light sources.

Several varieties of lasers can be used to treat acne and address the skin damage and scarring that is commonly associated with acne. New research has revealed that red and blue light therapies can inhibit bacterial growth and encourage healthy tissue to regenerate.

High intensity light within the red spectrum can reduce inflammation and promote the healing process. It encourages cells to proliferate and collagen to re-form. The research suggests that particular wavelengths of red light may be absorbed by important molecules that, once stimulated, induce cell growth and contribute to wound healing.

The same high intensity light in the blue spectrum is effective at killing the main bacteria that causes acne. According to clinical research, when blue light therapy is administered bi-weekly or daily, it can markedly reduce both the number and severity of acne lesions.

Light emitting diodes (LEDs) are commonly used to administer both light therapies, but lasers are used occasionally. Blue and red light therapy can be combined in photodynamic therapy (PDT) or intense pulsed light (IPL) treatment.


New Technology Reduces Laser Hair Removal Risks

The popularity of laser hair removal has grown in the last two years to become the third most requested non-surgical treatment. However, the quality of laser hair removal treatments has not caught up with the demand.

Sabrina Kozak, spa director of New York’s Sensitive Touch Medical Spa, warned that most laser treatment centres are not investing in the latest technology, which could result in less effective treatment and a higher risk of side-effects. Clients blinded by competitive online deals are not taking their time to research the best treatment options available with the latest advances in laser hair removal technology, she said.

Some of the undesirable side effects of laser hair removal include pigmentation, burns, and scars.

However, the Elite MPX laser by Cynosure is completely revolutionising the laser hair removal industry by reducing side-effects and delivering better results for many skin types. The technology makes it possible for an operator to fire multiple wavelengths at one time.

For the most effective treatment, Kozak recommends that clients search for providers who use this kind of cutting-edge laser technology.


Medical Laser Systems Market Remains Strong

A new report published by a US market research firm has revealed that the global market for medical laser systems is projected to reach an estimated value of US$ 2.0 billion by 2018.

The meteoric growth of the global medical laser systems market is largely due to an aging global population and a rise in age-related eye disorders. However, it can also be attributed to broader social and economic factors.

Advanced laser treatments are now more accessible to patients around the world and there is a growing emphasis on aesthetics. People living in countries with emerging economies, including Brazil, Russia, India, and China, have higher levels of disposable income and can more easily afford costly laser treatments.

The diode lasers market held the largest share of the market in 2011 and this is expected to continue throughout the forecast period. These lasers are widely used by medical practitioners in photodynamic therapy and a range of aesthetic treatments.

The solid state laser segment is predicted to experience the strongest growth between now and 2018. This segment has several variants and each has specific applications relating to medical treatments, including tattoo removal, periodontology, vein removal, and skin treatment.


Software Reduces Risks of Permanent Skin Damage from Laser Therapy

Australian James Bartholomeusz is spearheading the design of new software that minimizes the risk of permanent damage from skin laser therapy performed by dermatologists and plastic surgeons.

30-year-old Bartholomeusz is the global vice-president of product development for US medical device maker Syneron Candela, an organisation that manufactures laser, light, and radio frequency technology used for aesthetic purposes. He attributes the breakthrough development of his software to a ‘wildcard’ strategy, designed to encourage innovation.

The new software provides feedback to the operators of lasers already purchased from the company, via a simple upload. A feedback system of bright lights and beeps provides information about the precise amount of energy being delivered and its impact on the skin.

The algorithm of the software samples the skin at a rate of 1000 times per second. Information is taken from millions of data points and then cross-referenced in real time against records of patients from around the world.

Although the feedback system is mainly used for the treatment of acne scars and wrinkles, it has also proven to be an effective treatment for stretch marks. According to Bartholomeusz, his software can be used for anything to do with improving the skin.
