A major cause of skin aging is a chronic micro-inflammation triggered by UV radiation and external pollutants. It has been demonstrated that blue light diminishes inflammatory conditions and near infrared light enhances circulation.
To assess the effectiveness of a non thermal dual wavelength -- blue (405 - 420 nm) and near infrared (850 - 900 nm) -- light source in skin rejuvenation, in the reduction of the duration of post skin resurfacing erythema and in the acceleration of healing of post surgical conditions (face lift and breast augmentation).
We have utilized a non contact, hand free dual wavelength light source (iClearXL and Clear100XL, Curelight Ltd) to treat over 60 patients and perform three controlled studies in four centers. Follow up duration was three months. Control group for photo-rejuvenation consisted of patients treated with Glycolic peeling and daily appliance of vitamin C Control group for post skin resurfacing erythema duration consisted of patients untreated by the light source and control group for post surgical healing consisted of patients untreated by the light source or treated by the light source on one side only.
Post skin resurfacing erythema duration is reduced by 90%. The healing of post surgical conditions is substantially accelerated and discomfort is reduced. The anti aging effect of the light source includes: reduction of pore size in 90% of patients with stable results at three months follow up, enhanced skin radiance in 90% of patients with stable results at three months follow up and smoothing of fine wrinkles in 45% of patients with stable results at three months follow up. The control group showed poor results which were stable for a duration of less than one month.
A non thermal, non contact / hand free light source emitting at 405-420 nm and 850-900 nm considerably enhances aesthetic and surgical aesthetic procedures without consuming user time.
皮肤老化的一个主要原因是由紫外线辐射和外部污染物引发的慢性微炎症。已经证明蓝光可减轻炎症状况，近红外光可促进血液循环。
评估非热双波长（蓝光405 - 420纳米和近红外光850 - 900纳米）光源在皮肤年轻化、减少皮肤磨削术后红斑持续时间以及加速外科手术（面部提升和隆胸）后愈合方面的有效性。
我们使用了一种非接触、无需手持的双波长光源（iClearXL和Clear100XL，Curelight有限公司）治疗60多名患者，并在四个中心进行了三项对照研究。随访期为三个月。光嫩肤对照组由接受乙醇酸焕肤治疗并每日涂抹维生素C的患者组成。皮肤磨削术后红斑持续时间对照组由未接受光源治疗的患者组成，外科手术后愈合对照组由未接受光源治疗或仅一侧接受光源治疗的患者组成。
皮肤磨削术后红斑持续时间减少了90%。外科手术后的愈合得到显著加速，不适感减轻。光源的抗老化效果包括：90%的患者毛孔大小减小，在三个月随访时效果稳定；90%的患者皮肤光泽增强，在三个月随访时效果稳定；45%的患者细纹变平滑，在三个月随访时效果稳定。对照组效果不佳，且在不到一个月的时间内保持稳定。
发射405 - 420纳米和850 - 900纳米的非热、非接触/无需手持的光源可显著增强美容和外科美容手术效果，且不占用用户时间。
