Topical Formulation with Niacinamide Combined with 5 MHz Ultrasound for Improving Skin Ageing: A Double-blind, Randomised, Placebo-controlled Clinical Study.

Introduction: Skin ageing is a complex process influenced by various factors. Personal care products claim to address ageing signs, yet clinical efficacy tests lack standardised regulations. Niacinamide (NIA) is known for skin benefits, including managing hyperpigmentation and enhancing the barrier function.

Drug Delivery Systems based on Microneedles for Dermatological Diseases and Aesthetic Enhancement.

Microneedle (MN) devices comprise of micron-sized structures that circumvent biological barriers in a minimally invasive manner. MN research continues to grow and evolve; the technology was recently identified as one of the top ten overall emerging technologies of 2020. There is a growing interest in using such devices in cosmetology and dermatological conditions where the MNs mechanically disrupt the outer skin barrier layer, creating transient pathways that allow the passage of materials to underlying skin layers.

In vivo evaluation of topical ascorbic acid application on skin aging by 50 MHz ultrasound.

Introduction: Ascorbic acid (AA) is a powerful antioxidant capable of acting significantly both in the prevention and treatment of the skin aging process. One way to assess the in vivo efficacy of anti-aging treatments is by using the high-frequency ultrasound (HFUS) skin image analysis technique, a non-invasive approach that allows for a new level of evaluating the effectiveness of dermatological and cosmetic products. The aim of the present study was to assess the performance of a topical emulsion of liquid crystalline structures containing AA using the 50 MHz HFUS skin image analysis method.

Evaluation of skin using infrared thermal imaging for dermatology and aesthetic applications.

Introduction: The use of thermography in the medical field has been experiencing a renaissance due to advances in the infrared thermographic imaging technology, which improves thermographic equipment and promises cost saving and increased safety. Dermatology is one of the most promising fields of application among the medical areas with potential for the use of thermography.

Objective: To review the findings on this subject and to describe the use of such technique for dermatology and aesthetic applications.

High-frequency ultrasound as a scientific tool for skin imaging analysis.

Ultrasonic imaging is one of the most important diagnostic tools in clinical medicine due to its cost, availability and good correlation with pathological results. High-frequency ultrasound (HFUS) is a technique used in skin science that has been little explored, especially in comparison with other sites and imaging techniques. HFUS shows real-time images of the skin layers, appendages and skin lesions in vivo and can significantly contribute to advances in skin science.

Characterization of skin aging through high-frequency ultrasound imaging as a technique for evaluating the effectiveness of anti-aging products and procedures: A review.

Introduction: High-frequency ultrasound skin imaging analysis (HFUS) is a non-invasive technique that allows a unique approach to the analysis of skin aging, as well as in evaluating the effectiveness of dermatological and cosmetic products, especially for skin rejuvenation.

Objective: To describe the impact of skin aging and different anti-aging strategies from the perspective of high-frequency ultrasound.

Methods: A bibliographic survey was carried out, selecting relevant articles that evaluated the characterization of the skin features from different points of view such as gender (male and female), age (young skin and mature skin), and ethnicity, in addition to individual variations between body regions and daily variations.

Comparative sensory and instrumental analyses and principal components of commercial sunscreens.

Background: The initial contact of consumers when choosing sunscreens is through the trademark, packaging, perfume, and tactile feeling of the product, outlining the popular practice of sensory science.

Aims: To describe the sensory and physical-mechanical profile of commercial sunscreens through sensory and instrumental analyses related to principal component analysis (PCA).

Methods: Seven commercial sunscreens available on the Brazilian market and with a solar protection factor (SPF) of 30 were evaluated.

Skin effect of facial cleansing combined with an electric sonic device.

Background: New technologies, such as sonic devices, have been developed to optimize the skin cleansing process and improve its efficiency. To evaluate the effectiveness of these cosmetic procedures, skin bioengineering is an objective method to assess the biophysical parameters of the skin.

Aims: This study aimed to assess the effect of facial cleansing on the physiological properties of the skin by comparing a cleansing process with cosmetic product applied manually to cleansing with cosmetic product associated with the use of an electric sonic device.
