INTRODUCTION: Diesel particulate matter (DPM) emitted from diesel engines is a major source of air pollutants. DPM is composed of elemental carbon, which adsorbs organic compounds including toxic polycyclic aromatic hydrocarbons (PAH). The skin, as well as airways, are directly exposed to DPM, and association of atopic dermatitis, psoriasis flares, and premature skin aging with air pollutant levels has been documented. In skin, the permeation of DPM and DPM-adsorbed compounds is primarily blocked by the epidermal permeability barrier deployed in the stratum corneum...

BACKGROUND: The skin, particularly the epidermis, is subjected to various external stresses, including ultraviolet [UV] irradiation. UV irradiation, mainly UVB at wavelength of 280-315 nm, can alter several epidermal functions, including cutaneous inflammation, epidermal hyperproliferation, DNA damage, disruption of epidermal permeability barrier and reduction in stratum corneum hydration levels. Because of the negative impacts of UVB irradiation on epidermal functions, great efforts have been made to develop regimens for the protection of alterations in epidermal function induced by UV irradiation...

INTRODUCTION: Percutaneous drug delivery systems are attractive not only as a therapeutic strategy but also for cosmetic treatment. Iontophoresis is a well-recognized method for promoting transdermal absorption of ionized compounds. Franz cells are generally used to estimate drug permeation of skin by iontophoresis. However, methods using Franz cells are less versatile; for instance, the method is unsuited for use with a portable electric facial care device having a working probe of a certain size and weight...

INTRODUCTION: Compared to adults, newborns' skin has thinner epidermis and stratum corneum with decreased hydration level, higher transepidermal water loss, and pH variation between 5.5 and 7.5. These characteristics can predispose the occurrence of dryness, infections, and dermatological conditions. Water and liquid soap with adequate formulation have shown to be beneficial and safe for newborns' skin. However, studies evaluating the effect of bar soap, products widely used in Brazil and Latin America, are unknown...

INTRODUCTION: Folliculitis is a painful infection and inflammation of hair follicles, mostly caused by bacterial, fungal or, more rarely, viral infections. Turpentine derivatives have been used traditionally to treat various skin infections and could thus also be effective in treating folliculitis. We carried out an open, prospective, randomized, placebo- and comparator-controlled multicenter trial to evaluate the efficacy and safety of an ointment containing pine turpentine oil, larch turpentine, and eucalyptus oil in the treatment of acute folliculitis...

INTRODUCTION: Elastic skin fibers lose their mechanical properties during aging due to enzymatic degradation, lack of maturation or post-translational modifications. Dill extract has been observed to increase elastin protein expression and maturation in a 3D skin model, to improve mechanical properties of skin, to increase elastin protein expression in vascular smooth muscle cells, to preserve aortic elastic lamella and to prevent glycation. OBJECTIVE: The aim of the study was to highlight dill actions on elastin fibers during ageing thanks to elastase digestion model and the underlying mechanism...

BACKGROUND: For one half-century, cultures of human epidermal keratinocytes have opened new paths of research in skin biology and dermatology. Either performed with serum and feeder-layer, in serum-free conditions, or in autocrine conditions, cells cultured as monolayers became research materials for basic science and dermatology, as well as a source for grafting, particularly to treat severely burned patients. More recently tissue reconstruction at air-liquid interface has opened new perspectives for in vitro toxicology, studies of epidermal barrier, and modeling skin diseases...

BACKGROUND: The anatomic layers of the skin are well-described; recent research into the barrier capabilities of the skin has led to the development of a functional model of the skin barrier. Moisturization has been consistently recommended for use in conditions such as atopic dermatitis, in which barrier disruption plays a key role in disease. This review aims to analyze the skin barrier in the context of this function model, with a focus on the mechanisms by which moisturizers support each of the functional layers of the skin barrier to promote homeostasis and repair...

INTRODUCTION: The long-term use of topical corticosteroids (TCS) is associated with side effects such as skin atrophy and barrier deterioration. Moisturizers, such as mucopolysaccharide polysulfate (MPS), have been reported to prevent relapses in atopic dermatitis (AD) when used in combination with TCS. However, the mechanisms underlying the positive effects of MPS in combination with TCS in AD are poorly understood. In the present study, we investigated the effects of MPS in combination with clobetasol 17-propionate (CP) on tight junction (TJ) barrier function in human epidermal keratinocytes (HEKa) and 3D skin models...

INTRODUCTION: Along with climate changes, we see an increase in allergic symptoms and the number of pollen-allergic patients in many countries. Increased allergic symptoms are associated with an elevated ozone exposure which may be linked by impaired epithelial barrier function. This study aimed to quantify the clinical effect of ozone and pollen double exposure (DE). We tested whether ozone impairs barrier-related skin physiology and mucosal functions under double exposure with pollen ozone in grass pollen-allergic patients versus healthy controls...
