Y Qu, W-Y Ma, Q Sun
OBJECTIVE: The fractional laser and topical retinoic acid treatment have been applied for skin rejuvenation; however, the possible molecular mechanism of promoting remodeling of dermis is not clearly. Here we aimed to compare the effects of 10600 nm CO2 fractional laser and topical retinoic acid formulation on the skin collagen proliferation of Wistar rats, and to further explore the possible molecular mechanism of promoting remodeling of dermis. MATERIALS AND METHODS: The hair on the back of Wistar rats was removed, and the back was divided equally into four regions with the cross-streaking method: A (the control group), B (the retinoic acid group), C (retinoic acid and fractional laser combination treatment group), and D (the fractional laser group)...

Facial aging is a complex process individualized by interaction with exogenous and endogenous factors. The upper lip is one of the facial components by which facial attractiveness is defined. Upper lip aging is significantly influenced by maxillary bone and teeth. Aging of the cutaneous part can be aggravated by solar radiation and smoking. We provide a review about minimally invasive techniques for correction of aging signs of the upper lip with a tailored approach to patient's characteristics. The treatment is based upon use of fillers, laser, and minor surgery...

Beina Azadgoli, Regina Y Baker
In modern medicine, lasers are increasingly utilized for treatment of a variety of pathologies as interest in less invasive treatment modalities intensifies. The physics behind lasers allows the same basic principles to be applied to a multitude of tissue types using slight modifications of the system. Multiple laser systems have been studied within each field of medicine. The term "laser" was combined with "surgery," "ablation," "lithotripsy," "cancer treatment," "tumor ablation," "dermatology," "skin rejuvenation," "lipolysis," "cardiology," "atrial fibrillation (AF)," and "epilepsy" during separate searches in the PubMed database...

BACKGROUND AND OBJECTIVE: Hyperpigmentation is a common concern in Asian patients. Few published studies address overall skin rejuvenation in this group using long-pulse (LP) laser to target pigmentation and stimulate dermal remodeling. The LP KTP 532-nm laser (LP 532-nm) is used primarily to remove epidermal lesions, while the LP Nd: YAG 1064-nm laser (LP 1064-nm) is used to stimulate dermal remodeling in Asian patients with varying efficacy. The LP 532-nm used alone and in combination with LP 1064-nm to reduce pigmentation and rejuvenate skin was previously evaluated in lighter skin, but not in Asian skin...
