#influenced! The impact of social media influencing on self-esteem and the role of social comparison and resilience.

Social media influencers (SMIs) are online personas that acquire significant audiences on social networking sites (SNS) and have become a prevalent part of social media. Previous research indicates potentially detrimental effects of social media use on mental well-being, however, little is known about whether, how, and for whom online comparisons with SMIs lead to adverse psychological effects. In this study, we investigate the impact of positivity-biased images of female SMIs on the state self-esteem of female participants while considering social comparison processes as mediating and individual resilience as moderating factors.

Polysaccharide-based skin scaffolds with enhanced mechanical compatibility with native human skin.

We report a custom-made technique to synthesize process-convenient skin scaffolds by tuning the mechanical properties of hydrogels based on a few naturally occurring polysaccharides to match the rheological properties of previously established benchmarks, i.e., the ex vivo native human skins.

Hydrogel or ointment? Comparison of five different galenics regarding tissue breathability and transepidermal water loss.

Purpose: Five different galenics were analyzed and compared concerning tissue breathability and gas exchange with the environment after an application period of 6 h on pig ear skin. Aim was to find the most suitable galenics for efficient moist treatment for everyday injuries (abrasions, lacerations and cuts) without influencing the transepidermal water loss.

Methods: A quantity of 0.

Corneocyte Nanotexture as Biomarker for Individual Susceptibility to Skin Irritants.

Irritant contact dermatitis is a wide spread occupational skin condition. In addition to generalized protection and teaching schemes, a knowledge about individual risk might add to an improved awareness for hazards. Here, we report on a novel candidate biomarker, which might stage individual susceptibility to irritant skin damage.

Actinic keratosis and surrounding skin exhibit changes in corneocyte surface topography and decreased levels of filaggrin degradation products.

Actinic keratosis (AK) is a frequent premalignant skin lesion mainly caused by chronic sun exposure. AK lesions are often surrounded by invisible, subclinical alterations, called field of cancerization (FoC). Definition of FoC is of importance for therapy management; however, the criteria and non-invasive tools to characterize FoC are lacking.

Linear viscoelastic and microstructural properties of native male human skin and in vitro 3D reconstructed skin models.

The study reports first ever account of measurements of linear viscoelastic moduli under small amplitude oscillatory shear deformations, for commercially available juvenile and aged in vitro 3D reconstructed skin models. The results were compared with those of native male whole human and dermis-only foreskin samples, catering to a wide age group from 0.5 to 68 years, including samples from a 23-year-old male abdomen.

[Hyaluronan as a key for accelerated wound healing in human 3D full thickness skin models].

Background: Wound healing can be divided into three phases: (1) exsudation phase, (2) granulation phase, (3) regeneration phase. In particular, the epithelization phase is of great importance in order to quickly reconstitute the natural skin barrier. The aim of the present study was to determine the reepithelization kinetics of untreated and 0.
