The presence of dark melanin (eumelanin) within human epidermis represents one of the strongest predictors of low skin cancer risk. Topical rescue of eumelanin synthesis, previously achieved in "redhaired" Mc1r-deficient mice, demonstrated significant protection against UV damage. However, application of a topical strategy for human skin pigmentation has not been achieved, largely due to the gr...
OBJECTIVE To determine the efficacy of topical anti-ischemic drug therapy in the salvage of failing, random-pattern skin flaps. DESIGN Prospective, randomized, placebo-controlled, therapeutic trial. SETTING Academic medical center. SUBJECTS Sixty-one adult male Sprague-Dawley rats. INTERVENTION Each experimental rat underwent a caudally based random-pattern skin flap using the modified ...
Topical administration permits targeted, sustained delivery of therapeutics to human skin. Delivery to the skin, however, is typically limited to lipophilic molecules with molecular weight of < 500 Da, capable of crossing the stratum corneum. Nevertheless, there are indications protein delivery may be possible in barrier deficient skin, a condition found in several inflammatory skin diseases su...
The development of topical anesthetics has provided the family physician with multiple options in anesthetizing open and intact skin. The combination of tetracaine, adrenaline (epinephrine), and cocaine, better known as TAC, was the first topical agent available for analgesia of lacerations to the face and scalp. Cocaine has been replaced with lidocaine in a newer formulation called LET (lidoca...

There are many) topical therapies availablte/for managingp ruritus. Emergin;g therapies include dominant ceramide moisturizers, topical immunomodulators, low pH moisturizers, topical aspirin, and combinations of moisturizers w...
Nanostructured lipid carriers (NLC) exhibit high skin targeting efficiency and good safety. They are promising vehicles for topical drug delivery. This study aims to increase the skin distribution of podophyllotoxin (POD) by incorporating it into NLCs. Two kinds of POD-loaded NLCs (POD-NLCs)-POD-NLCformulation 1 and POD-NLCformulation 2-were prepared and characterized. Their skin targeting effi...
UNLABELLED Abstract Background: Skin laxity and cellulite on the buttocks and thighs are two common cosmetic concerns. Skin tightening with radiofrequency (RF) devices has become increasingly popular. OBJECTIVE The purpose of this study is to evaluate the efficacy and safety of a topical skin laxity tightening agent when used in combination with an RF device. METHODS A double-blinded, rando...
Production of type I collagen (COL1), the major structural protein of the skin, declines during aging, leading to skin thinning and becoming fragile, which increases the risk of bruising and wound healing disorders in the elderly. Topical treatments that can restore COL1 synthesis and ultimately COL1 content in aged skin hold promise to improve skin health. Much effort has been spent on develop...
