Exposure to sunlight and artificial light sources containing ultraviolet (UV) radiation is known to accelerate the skin's aging process, resulting in unwanted wrinkles, irregular skin tone, and loss of elasticity. Ablative techniques, such as dermabrasion, deep chemical peels, and ablative laser resurfacing of various wavelengths, are well documented to alleviate the signs of photodamage. However, such techniques often require significant post-treatment care and have higher risk profiles than other treatments, with potential side effects including erythema, pigmentation issues, infection, and possible scarring. They may be poorly tolerated by patients who dislike the discomfort, wound care, and prolonged downtime involved.
Non-ablative skin rejuvenation procedures are also effective for improving the appearance of photodamaged skin and are becoming increasingly popular because of their minimal downtime and increased safety. These procedures include intense pulsed light systems, non-ablative lasers, and monochromatic light boxes, which can target facial rhytids, irregular pigmentation, telangiectasia, and skin laxity. Unfortunately, such techniques can be expensive and their use is primarily limited to clinical settings.
However, the light-emitting diode (LED) is a novel light source that is well-suited for non-ablative phototherapy that can be utilized at home for a relatively low price. This study will evaluate the efficacy and tolerance of an LED-based light therapy mask as compared to a sham mask in subjects seeking anti-aging benefits.
