Abstract Purpose This cases report introduces new technique of lip rejuvenation, we studied the non-ablative photorejuvenation effect on lip, which keep the superficial layer intact and patient can resume their lifestyle after photorejuvenation, with totally painless procedure. Methods The procedure was done on lips of two female patients, with 660nm diode laser, the sessions were repeated four times for each patient, photographs were taken before and after, then measurements of overall lip index were obtained for upper and lower lips. Results The overall volume of lips was increased, the lip’s texture was improved. Conclusion This case report shows that 660nm wavelength with our protocol was successful to rejuvenate and augment the lips. Keywords Photobiomodulation . Photorejuvenation . Non-ablative .

Introduction The popularity of non-invasive cosmetic adjustment of the lips and face is growing amongst patients and practitioners alike, specially the most photoaged parts of the body are the face and lips due to exposure to sun daily. Additionally, the shape of the lips contributes to the noticeable signs of aging. Therefore, understanding skin aging mechanism is the key point in order to correctly and effectively counteract effects on the skin using proper and safe intervention modalities. Photoaged skin or lips was characterized by progressive disorientation of dermal collagen and elastic fibers bundles, as well as increase in space between fiber bundles, thinning of fibers, and increased disorganization of fiber proteins. From here, many techniques were developed to give lips the volume, smooth texture, and homogenous color. From topical pharmacological agents, to more invasive methods by resurfacing the epidermis to promote collagen formation

either by chemical peel or laser resurfacing or by injectable skin rejuvenation or dermal fillers [1]. Due to aggressive methods in some modalities, which ablate the epidermal layer, scarring or permanent pigmentary alterations may result, also healing or infectious complications can occur, as healing period extend from 1 to 2 weeks. Other method as injectable filler is a very painful procedure, and post-injection edema can occur in the healing period. Alternatively, it was concluded [2] that laser therapy speeds up the process of tissue repair for photoaged skin, which lost mature collagen, despite the divergences in application parameters, which used by included studies in the review. Moreover, different wavelengths were discussed in Weiss et al. review [3], which was done clinically on patients and showed good results in collagen f
