OBJECTIVE To determine the efficacy of an over-the-counter topical skin adhesive pad for reducing central forehead and glabellar rhytids over a 4-week period. DESIGN Prospective series involving 30 healthy volunteers with central forehead and glabellar rhytids at a tertiary care academic medical center. The participants used topical skin adhesive pads over the central forehead area and the gl...
BACKGROUND Several laser technologies exist for improving rhytides, pigmentation, and skin texture. Recent advances in technology introduced a new wavelength, 2,790 nm, erbium:yttrium-scandium-galium-garnet (Er:YSGG) for treatment of photoaging. 2,790 nm Er:YSGG has a water absorption coefficient between CO(2) laser and Er:YAG laser and has both ablative and fractional-ablative capabilities. ...
With the increase in life expectancy, there is also growing interest in anti-aging treatments and technologies. The development of anti-aging functional drugs for the skin, and foods from natural sources, may offer solutions to this global matter. Aging involves structural, functional and biochemical changes that occur throughout cells and bodily tissues; the amount of hormones secreted from of...
Ultraviolet B (UVB; 290~320nm) irradiation-induced lipid peroxidation induces inflammatory responses that lead to skin wrinkle formation and epidermal thickening. Peroxisome proliferator-activated receptor (PPAR) α/γ dual agonists have the potential to be used as anti-wrinkle agents because they inhibit inflammatory response and lipid peroxidation. In this study, we evaluated the function of 2-...
A compressed elastic film on a compliant substrate can form wrinkles. On an elastic substrate, equilibrium and energetics set the critical condition and select the wrinkle wavelength and amplitude. On a viscous substrate, wrinkle grows over time and the kinetics selects the fastest growing wavelength. More generally, on a viscoelastic substrate, both energetics and kinetics play important roles...
OBJECTIVE To compare the efficacy, adverse effects, and histological findings of erbium:YAG (Er:YAG) and carbon dioxide (CO2) laser treatment in removing facial rhytides. DESIGN An intervention study of 21 subjects with facial rhytides. All participants were followed up for 6 months. The end points of the study were wrinkle improvement and duration of adverse effects. SETTING Academic refer...
BACKGROUND Tretinoin is considered the benchmark prescription topical therapy for improving fine facial wrinkles, but skin tolerance issues can affect patient compliance. In contrast, cosmetic antiwrinkle products are well tolerated but are generally presumed to be less efficacious than tretinoin. OBJECTIVES To compare the efficacy of a cosmetic moisturizer regimen vs. a prescription regimen ...
