We aimed to investigate the efficacy and safety of using the 1064-nm Q-switched neodymium-doped yttrium aluminum garnet (Nd:YAG) laser (QSNYL) for skin rejuvenation in patients with Nevus of Ota. A retrospective, randomized, split-faced, clinical study was conducted. Twenty-nine patients with unilateral moderate to severe Nevus of Ota were enrolled. The participants completed 3-13 sessions of QSNYL treatments 3-6 months apart. Two independent physicians compared the treated and untreated sides of the face to evaluate the clearance of Nevus of Ota, the wrinkle severity rating scale (WSRS), the global aesthetic improvement scale (GAIS), and adverse event reporting...

The growing incidence of non-melanoma skin cancer (NMSC) necessitates a thorough understanding of its primary risk factors, which include exposure to ultraviolet (UV) wavelengths of sunlight and age. Whereas UV radiation (UVR) has long been known to generate photoproducts in genomic DNA that promote genetic mutations that drive skin carcinogenesis, the mechanism by which age contributes to disease pathogenesis is less understood and has not been sufficiently studied. In this review, we highlight studies that have considered age as a variable in examining DNA damage responses in UV-irradiated skin and then discuss emerging evidence that the reduced production of insulin-like growth factor-1 (IGF-1) by senescent fibroblasts in the dermis of geriatric skin creates an environment that negatively impacts how epidermal keratinocytes respond to UVR-induced DNA damage...

Pueraria candollei var. mirifica or White Kwao Krua (WKK) is a phytoestrogen-rich plant widely used among women to improve climacteric symptoms. Additionally, the tuberous roots of this plant have been added as an active ingredient for skin rejuvenation and breast enlargement effects in various functional foods. However, most of the products on the market containing WKK have not been sufficiently standardized with respect to the active compound or identical marker. To control the quality of these plant materials, an enzyme-linked immunosorbent assay (ELISA) using anti-isomiroestrol antibodies was established for the determination of isomiroestrol, an identical marker in WKK...

BACKGROUND: Ultrasound is a mechanical wave that transmitted in a straight line and it can be focused at frequencies of 1-7 MHz with a high degree of precision. An important aspect of HIFU is that damaging focal point is located several millimeters below the surface of the skin and tissue above and below the focal point remains unaffected. Due to absorption of this energy, temperature of tissue rises to more than 60°C and this stimulates the cells for collagen production and tissue rejuvenation...

BACKGROUND: A high rate of recurrence of anterior platysma bands and anterior skin laxity was reported at the 1-year follow-up of 150 patients who underwent complete neck undermining and full-width platysma transection for neck rejuvenation. The authors propose a new technique-lateral skin-platysma displacement-to treat these two aesthetic problems using only a lateral approach to avoid "opening" the anterior neck. The authors' objective was to compare outcomes following full-width platysma transection technique and lateral skin-platysma displacement technique in terms of patient satisfaction, complications, and long-term effectiveness in the treatment of bands and anterior skin laxity...

Operating at multiple levels of control, mesenchymal stem cells from adipose tissue (ADSCs) communicate with organ systems to adjust immune response, provide signals for differentiation, migration, enzymatic reactions, and to equilibrate the regenerative demands of balanced tissue homeostasis. The identification of the mechanisms by which ADSCs accomplish these functions for dermatological rejuvenation and wound healing has great potential to identify novel targets for the treatment of disorders and combat aging...

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...

Highly proliferative tissues such as the gut, skin, and bone marrow lose millions of cells each day to normal attrition and challenge from different biological adversities. To achieve a lifespan beyond the longevity of individual cell types, tissue-specific stem cells sustain these tissues throughout the life of a human. For example, the lifespan of erythrocytes is about 100 days and adults make about two million new erythrocytes every second. A small pool of hematopoietic stem cells (HSCs) in the bone marrow is responsible for the lifetime maintenance of these populations...
