BACKGROUND: Recently, the pulse-in-pulse mode of intense pulsed light (IPL) has been used increasingly for the treatment of melasma. OBJECTIVE: To observe the morphologic changes in the melanophore in adult zebrafish after irradiation with conventional and pulse-in-pulse IPL and Q-switched Nd:YAG (QSNY) laser. METHODS: Adult zebrafish were irradiated with conventional and pulse-in-pulse mode of IPL. The conditions for conventional IPL were 3 mJ/cm(2), 560 nm filter, and pulse widths of 7, 20, and 35 msec...

Rosacea is characterised by a wide variety of vascular changes. Apart from telangiectasia and erythema, often so-called flushing occurs. These vascular abnormalities can be targeted with specific light and laser devices. In addition to KTP laser, pulsed dye laser (PDL) and Nd:YAG laser, also intense pulsed light devices (IPLs) are used. The described therapeutic effects include the reduction of vascular abnormalities and even improvement of papulopustular changes. While the KTP laser shows very good results in telangiectasia, the dye laser and IPL devices are used preferably in erythema...

Die Rosazea ist durch vielfältige vaskuläre Veränderungen gekennzeichnet. Neben Teleangiektasien und Erythemen treten häufig auch sogenannte "Flushings" auf. Haupteinsatzgebiete von Licht- und Lasersystemen sind diese vaskulären Veränderungen, wie Erytheme und Teleangiektasien. Neben dem KTP-Laser, dem Farbstofflaser (PDL) und dem Nd:YAG-Laser kommen auch Blitzlampen (IPL) zum Einsatz. Neben der Rückbildung der vaskulären Komponente, ist auch eine Verbesserung der papulopustulösen Komponente beschrieben...

Asian skin has a higher epidermal melanin content, making it more likely to develop adverse pigmentary reactions following laser surgery. The nanosecond lasers are the gold standard for the treatment of pigmented lesions, but the risk of complications, such as post-inflammatory hyperpigmentation, is increased in dark-skinned patients. Intense Pulsed Light (IPL) or long-pulsed lasers are available for treating superficial pigmented lesions, and fewer complications are seen when using these devices compared to the nanosecond lasers...

BACKGROUND: Post inflammatory hyperpigmentation (PIH) is a common problem occurs following many dermatologic diseases and medical interventions. Different modalities including topical agents, lasers and intense pulsed light (IPL) are suggested for treatment of the post-burn PIH. In the current study, we evaluated the efficacy of IPL plus modified Kligman cream (MODIFIED KLIGMAN CREAM) versus MODIFIED KLIGMAN CREAM alone in the treatment of the post-burn PIH. MATERIALS AND METHODS: This was a randomized, non-blinded clinical trial...

BACKGROUND AND AIMS: The use of multiple, sequential light and laser sources for topical ALA activation in photodynamic therapy (PDT) of rosacea has been largely absent from the literature. The aim of this study was to evaluate ALA-PDT for rosacea using blue light sequentially with red light, pulsed-dye laser (PDL), and/or intense pulsed light (IPL). PATIENTS/METHODS: Thirty patients (39 treatments) were enrolled in this retrospective, single-center study. Treatment groups included blue light + PDL, blue light + IPL, blue light + PDL + IPL, or blue light + red light + PDL + IPL...

Dyschromia is a leading cause for cosmetic consultation, especially in those with diverse skin types (mixture of ethnicities) and with the rise of non-core and untrained physicians performing cosmetic procedures. Melasma and post-inflammatory hyperpigmentation (PIH) account for the majority of cases and are characterized by pigmented macules and patches distributed symmetrically in sun-exposed areas of the forehead, cheeks, and chin in melasma, and irregularly in areas of inflammation or an inciting traumatic event with PIH...

BACKGROUND: Photodamaged skin of the chest is characterized by skin laxity, lines/wrinkles, hyperpigmentation, erythema, tactile roughness, atrophy, and telangiectasias. METHODS: A MEDLINE search was performed on combination treatments in chest rejuvenation, and the results are summarized. Practical applications for these combinations of procedures are discussed. RESULTS: Reports of injectable poly-L-lactic acid (PLLA), hyaluronic acid (HA), and chemical peels, along with lasers and light therapies such as intense pulsed light (IPL), vascular lasers, photodynamic therapy (PDT), nonablative fractionated lasers (NAFLs), ablative fractionated lasers (AFLs), and microfocused ultrasound (MFU) have been reported for chest rejuvenation...

BACKGROUND: Intense pulsed light (IPL) and 1,064-nm Nd:YAG laser are both being used for the treatment of vascular lesions. This study compared the treatment efficacy of combined therapy versus separately delivery of IPL or 1,064-nm Nd:YAG laser in facial telangiectasia in a split face study design. METHODS: Twenty-four patients were studied using the sequential delivery of IPL and Nd:YAG laser on one side of the face (combined therapy side). The other side received IPL treatment first followed by Nd:YAG treatment 3 days later (separated therapy side)...

UNLABELLED: A melanin meter has been created to assess real time skin pigmentation to optimize settings for visible light aesthetic applications. METHODS: A handheld meter was applied to non sun-damaged skin on the back of volunteers to measure skin pigmentation prior to treatment with IPL light sources over a range of pulse widths and ascending fluences. Curves for maximum epidermal tolerances as a function of pigmentation were determined. These curves were then tabulated for each pulse width in device software to provide guidance in the selection of fluences...

INTRODUCTION AND OBJECTIVES: This qualitative review of paradoxical hair growth, following professional treatments reviews, clarifies whether low fluence is the most probable cause of unwanted hair regrowth after at home light-based treatments. MATERIALS AND METHODS: The proposed causes of unexpected hair regrowth are examined, and our scientific understanding of absorption and scattering of light in turbid tissue is reviewed. Published reports of paradoxical hair growth are assessed...

OBJECTIVE: Evaluation of the efficacy and side effects of neodymium-doped yttrium aluminum garnet (Nd:YAG) laser and Nd:YAG laser-intense pulsed light (IPL) combination treatments in photorejuvenations of skin of the hand, and determining their impacts on patient satisfaction. MATERIALS AND METHODS: Thirty-five female patients with signs of photoaging on the skin of their hands were included in the study. Three sessions of IPL and four sessions of Nd:YAG laser treatment were applied to the right hand in total with 2-week intervals between each session, whereas six sessions of Nd:YAG laser treatment were applied to the left hand of patients with 2-week intervals between each session...

OBJECTIVE: To further evaluate the safety and effectiveness of bipolar RF-based optical therapy combining intense pulsed light (IPL), infrared light, and diode laser in the treatment of photoaged skin in Chinese subjects. METHODS: Twenty-seven subjects received five treatments at 3-week intervals. Triple therapy was applied in one session to the face. Images and data were obtained 30 and 180 days after the last treatment. Objective measurements (including photometric analysis of skin pigmentation, texture and wrinkles, ultrasonic measurement of dermal thickness and dermal echo intensity, and public and self-assessment of apparent age), clinical assessment, and safety were evaluated...

PURPOSE: Platelet-derived growth factor (PDGF) promotes neuronal survival in experimental glaucoma and recruits glial cells that regulate synapses. We investigated the effects of intravitreal PDGF on the inflammatory milieu and retinal synapses in the presence of raised IOP. METHODS: Animals with laser-induced IOP elevation received intravitreal injections of either saline or 1.5 μg PDGF. At 7 days, a further intravitreal injection was administered so groups received "PDGF-saline" (n = 15), "PDGF-PDGF" (n = 13), or "saline-saline" (n = 20)...

BACKGROUND: Postinflammatory hyperpigmentation (PIH) is an acquired hypermelanosis induced by various causes including inflammatory dermatoses, injury, or cosmetic procedures, such as lasers or chemical peels, and it tends to affect dark-skinned people with greater frequency and severity. There are a variety of treatment options for PIH, including topical agents, chemical peels, laser, and light therapy. However, the results are not up to expectation. OBJECTIVE: The purpose of this study was to examine the clinical efficacy and safety of novel pulse-in-pulse mode intense pulsed light (IPL) for the treatment of persistent facial PIH in Korean patients...
