Eye Elasticity

Evaluating Fractional Laser Treatments to Improve Skin Elasticity

There are various methods used in cosmetic dermatology to improve skin elasticity and reduce wrinkling in the eye area and multiple ways to evaluate the effectiveness of each treatment. Some methods for evaluating treatments include measurements of skin elasticity (reviscometer), evaluation of mechanical skin properties (cutometer), tests based on computer images, and photographic documentation and posttreatment surveys.

A recent study used Cutometer (Courage+Khazaka electronic) to measure biomechanical properties of the skin after treatment with non-ablative fractional laser around the eye. The Cutometer is a noninvasive device that uses negative pressure to measure elasticity of the upper skin layer. Photographic documentation was used to compare changes after the series of treatment sessions, and the patients were surveyed to self-evaluate the procedure. This study included 24 patients (21 women, three men), aged 33–50 years (the average age was 44.6) with Fitzpatrick skin type II and III.

After five successive 1410-nm non-ablative fractional laser treatment sessions, given in 2-week intervals, a Cutometer was used to evaluate biomechanical skin properties. Based on the photographic documentation, the results showed a decrease in the quantity and depth of wrinkles and the survey indicated a significant improvement of tightness in the eye area. Cutometric analysis showed a significant improvement of skin elasticity. The authors note that because the photographic documentation is subjective, the cutometric measurement provides an objective evaluation of the changes occurring during and after the treatment sessions.

They concluded that 1410-nm non-ablative fractional laser treatment is an effective method for rejuvenating the skin in the eye area. It contributes to both the quantity and depth of wrinkles and improves skin tightness. The authors state that cutometric measurement can be used to effectively and objectively assess anti-aging treatments, while photographic documentation is an excellent addition to the clinical tests.
