Haptic skin palpation with three‐dimensional skin surface reconstruction from in vivo skin images in order to acquire both tactile and visual information has been receiving much attention. However, the depth estimation of skin surface, using a light field camera that creates multiple images with a micro‐lens array, is a difficult problem due to low‐resolution images resulting in erroneous...
Some methodologies used for evaluating sweat production and antiperspirants are of a stationary aspect, that is, most often performed under warm (38°C) but resting conditions in a rather short period of time. The aim is to develop an electronic sensor apt at continuously recording sweat excretion, in vivo, during physical exercises, exposure to differently heated environments, or any other...
The scope of this study was to utilize confocal Raman spectroscopy in the evaluation of the degree of non‐penetration into the viable skin layers of a paraffin and petrolatum‐based product for use in the intimate areas of the skin. The formulation was purposely designed with properties to prevent undesirable skin penetration.
Product—The test product was a proprietary topical...
The clinical characteristics of skin were investigated to study the inter‐relationship and changes in the biophysical properties of the epidermal and dermal layers associated with aging using noninvasive methods.
Our study included 100 healthy women aged between the early 20s and late 60s. Biophysical characteristics of skin such as color (brightness and spots), transparency,...
To investigate the characteristics of hairs in Female pattern hair loss (FPHL) patients and healthy females in Southern China.
Materials and methods
Three fundamental hair parameters in different scalp areas of 90 Southern Chinese FPHL patients and 83 healthy controls were analyzed by phototrichogram.
Female pattern hair loss patients showed reduced hair density, hair diameter,...
Facial features vary in size and proportions between different races. This study aimed to measure the anthropometric variables of the labial region in Han Chinese young adults.
Materials and Methods
A total of 900 college students (475 male and 425 female) of Chinese Han ethnicity from the northern China were included. Measurements of the labial region included 14 linear items and seven...
In skin beauty area, interest in diagnosis and management methods for acne is increasing. However, it is difficult to diagnose protruding skin disease by two‐dimensional (2D) image. Three‐dimensional (3D) approach is needed. The purpose of this study was to propose a system for reconstructing 3D model (visual hull) of 2D images obtained using mobile devices.
Microneedle fractional radiofrequency (MNRF) is a minimally invasive technique that delivers radiofrequency (RF) energy into the skin via microneedles. Reflectance confocal microscopy (RCM) and optical coherence tomography (OCT) enable the characterization of device‐tissue interactions in in vivo skin. The aim of this study is to describe MNRF‐induced micropores using RCM and OCT imaging...
Nipple pain is the second most common reason for early weaning, exceeded only by the insufficient milk supply. Nipple fissures can bring other problems, acting also as a portal for bacteria and leading to mastitis. This work proposes the breast protector composite development using materials with tissue repair and moisturizing properties, aligned with a low‐cost procedure, aiming not only...
The objective of this study was to perform noninvasive analysis of skin proteins in a healthy Chinese population using label‐free nanoflow liquid chromatography‐mass spectrometry (nLC‐MS).
Materials and Methods
Five consecutive tape strippings were obtained from the volar forearm skin of healthy Chinese subjects. Proteins were extracted, and trypsin‐digested peptides were analyzed by...
We present a classifier for automatically selecting a lesion border for dermoscopy skin lesion images, to aid in computer‐aided diagnosis of melanoma. Variation in photographic technique of dermoscopy images makes segmentation of skin lesions a difficult problem. No single algorithm provides an acceptable lesion border to allow further processing of skin lesions.
We present a random...
During sleep, the skin is exposed to various environments for example low or high humidity and temperature. And the average of 7‐8 hours of sleeping in those situations can affect skin condition. Therefore, the objective of this study was to determine skin characteristics according to humidity during sleep.
Eleven healthy women in their ages of 20s and 30s were controlled. They...
Actinic keratosis (AK) is a common premalignant skin lesion that can potentially progress to squamous cell carcinoma. Appropriate long‐term management of AK requires close patient monitoring in addition to therapeutic interventions. Computer‐aided diagnostic systems based on clinical photography might evolve in the future into valuable adjuncts to AK patient management. The present study...
Estimating the extent of affected skin is an important unmet clinical need both for research and practical management in many diseases. In particular, cutaneous burden of chronic graft‐vs‐host disease (cGVHD) is a primary outcome in many trials. Despite advances in artificial intelligence and 3D photography, progress toward reliable automated techniques is hindered by limited expert time...
The stabilizing effect of lavender and the arousal effect of peppermint essential oils are acknowledged and used widely in aromatherapy and the cosmetics industry. However, no evaluation method confirms the effects of essential oils through quantitative and objective electroencephalogram (EEG) results; instead, only a psychological and subjective method exists. Therefore, this study aims...
Despite a strong desire to quantify skin radiance in the field of cosmetics, there does not exist a robust method to characterize it. Classical shine that quantifies the specular reflection from skin has been commonly used as the metric to characterize radiance. However, it does not always correlate with the perceived radiance as there are many other parameters that inform radiance perception...
The main objective of this study was to determine the lipid profile of brown and white Caucasian hair fibres and the effects of lipids on the properties of fibres.
Materials and Methods
To determine the structures of white and brown hair lipid bilayers, cross sections of fibres of both hair types were examined using synchrotron‐based μ‐FTIR mapping. Dynamic vapour sorption (DVS) analyses...
