BACKGROUND The use of visible or near infrared spectral light alone for the purpose of skin rejuvenation has been previously reported. A method of light emitting diode (LED) photo rejuvenation incorporating a combination of these wavelengths and thus compounding their distinct stimulation of cellular components is proposed.Objective. To assess the efficacy and local tolerability of combination ...

BACKGROUND Rejuvenation of the aging chest is important to prevent noticeable disparities between the treated skin of the face and that of the untreated chest. OBJECTIVE To compare a high-density thulium fiber laser (TFL)-based protocol for the rejuvenation of the aging chest with intense pulsed light (IPL). METHODS AND MATERIALS We conducted a retrospective chart review comparing patients ...

BACKGROUND There is a move toward a global, 3-dimensional approach to facial rejuvenation that has been prompted by advances in techniques and available products. However, little published literature exists on the procedures involved in this global approach, and currently, no validated recommendations exist. OBJECTIVES To provide a detailed, practical guide to rejuvenation of the perioral are...

BACKGROUND Platelet-rich plasma (PRP) is researched and used in many clinical fields as it contains an abundance of various growth factors. Recently, a topical injection of PRP has been clinically tried for treatment of photoageing-related skin wrinkles. Nevertheless, there have been only a few studies including objective data or explaining the mechanisms of PRP. Therefore, the authors performe...

In this paper, we extend the classical result by Huang, Kintala, Kolettis and Fulton (1995), and in addition propose a modified stochastic model to determine the software rejuvenation schedule. More precisely, the software rejuvenation models are formulated via the semi-Markov processes, and the optimal software rejuvenation schedules which maximize the system availabilities are derived analyti...

PURPOSE Many treatment modalities exist to counteract the effects of cutaneous aging. Ablative methods have been the mainstay for nonsurgical facial rejuvenation. In recent years, nonablative techniques have been developed with the aim of achieving facial rejuvenation without epidermal damage. Light-emitting diode (LED) photorejuvenation is a novel nonablative technique that induces collagen sy...

Software rejuvenation is a preventive maintenance technique that has been extensively studied in the recent literature. In this paper, we extend the classical result by Huang, Kintala, Kolettis and Fulton (1995), and in addition propose a modified stochastic model to generate the software rejuvenation schedule. More precisely, the software rejuvenation models are formulated via the semi-Markov ...

objectives this study aimed to evaluate the efficacy of afcl in improvement of hand photoaging in 25 patients. patients and methods a prospective, before- after, single blind study was conducted in 25 patients who presented for desired treatment of hand photoaging. patients received three treatments sessions with afcl. results all enrolled patients were female and received three treatment sessi...
