Fractional photothermolysis is a new technique for the treatment of skin lesions in which an array of microscopic thermal wounds (microscopic treatment zones) is induced into the skin to stimulate a therapeutic response deep in the dermis. articolo completo Autori Moshe Lapidoth Marina Emiko Yagima Lilian Mayumi
Manipolo Pixel CO2 Omnifit per Resurfacing frazionale ablativo microspopico della pelle – studio in vivo
/ studio
I tradizionali dispositivi laser CO2, sono altamente efficaci nello skin resurfacing, ma sono associati con tempi di recupero prolungati e rilevanti effetti negativi. La modalità non ablativa offre tempi di inattività ridotti e minori effetti collaterali, ma l’efficienza è limitata. Il nuovo manipolo laser CO2 frazionato produce una matrice di ferite microtermiche a profondità personalizzabile […]
Fractional 1320 nm Nd : YAG laser in the treatment of acne vulgaris: a pilot study
/ studio
Acne vulgaris is a common skin condition, affecting over 85% of people. Because of its effect on quality of life, acne vulgaris is more than a merely physiological or cosmetic entity. Acne is caused by changes in the pilosebaceous units. Patients have excess sebum production and non-inflammatory follicular papules. Proliferation of Propionibacterium acnes may lead […]
Mapping pigmentation in human skin from multi-channel visible spectrum image by inverse optical scattering technique
/ studio
Mapping pigmentation in human skin is expected to give useful information in reproducing skin color and enhancing the ability to diagnose various skin disease. In this research, maps of melanin, oxyhemoglobin and deoxy-hemoglobin in skin are estimated from multichannel visible spectrum image by using an inverse optical scattering technique. In the inverse optical scattering technique, […]
Ablation and Thermal Depths in VSP Er:YAG Laser Skin Resurfacing
/ studio
The list of indications for which Variable Square Pulse (VSP) Er:YAG laser systems can be used is continuously expanding. For example, ablative fractional resurfacing treatments performed with the VSP Er:YAG laser have good clinical outcomes and significantly shorter recovery times and adverse effects compared with traditional ablative laser skin resurfacing. Recently, an Er:YAG laser operating […]
Epidermal Thickness at Different Body Sites: Relationship to Age, Gender, Pigmentation, Blood Content, Skin Type and Smoking Habits
/ studio
Epidermal thickness and its relationship to age, gender, skin type, pigmentation, blood content, smoking habits and body site is important in dermatologic research and was investigated in this study. Biopsies from three different body sites of 71 human volunteers were obtained, and thickness of the stratum corneum and cellular epidermis was measured microscopically using a […]
The Appearance of Human Skin
/ studio
Skin is the outermost tissue of the human body. As a result, people are very aware of, and very sensitive to, the appearance of their skin. Consequently, skin appearance has been a subject of great interest in several fields of science and technology. As shown in Figure 1, research on skin appearance has been intensely […]
L'ottica della pelle umana
/ studio
Viene presentata una revisione integrata del trasferimento della radiazione ottica nella pelle umana, finalizzata a sviluppare modelli utili per la foto-medicina. articolo completo Autori R. Rox Anderson John A. Parrish
The optics of human skin: Aspects important for human health
/ studio
Human health can be strongly influenced by exposure to solar radiation. Interactions relevant for health take place mainly in the skin. In this context the optics of human skin is of the utmost importance. Reflection, scattering and absorption are the optical properties affecting the nature of these interactions. By combining a bio-optical model of human […]
