Researchers Construct 3-D Bioprinted Skin Pigmentation

Bioprinted skin can now incorporate accurate skin pigmentation patterns, as reported by new research published in Biofabrication.

Oxygen Breathes Life Into Hair Regeneration Research

Oxygen-permeable silicone was the key to recent research in Biomaterials, developed in hopes to bring about new hair regeneration treatments.

BRAIN AG and Mannheim University of Applied Sciences Publish Article on 3D Skin Models

The article provides a comprehensive table comparing available 3D skin models.

New In Vitro Data for Alban Muller's Protectami Skin Defense Solution

The ingredient was found to increase skin elasticity by activating the synthesis and maturation of elastin, while decreasing the activity of elastase enzymatic degradation. It also increased cytokeratins and desmosomial proteins, and improved cell communication between keratinocytes.

SILAB Introduces Reconstructed Skin Models

SILAB Research has created SILABSKIN multi-layer reconstructed epidermis or skin models to test the efficacy of its natural cosmetic actives in vitro.

DSM Discovers Efficacy in ReguScence

DSM’s new research findings confirmed the efficiency in even skin tone application from the ingredient, ReguScence.

Marigold Extract Photoprotection Breakthrough

Kemin reported new in vitro studies confirm the blue-light-absorbing capacity of its marigold-derived FloraGLO Lutein Topical product.

A Novel Explant Model for Skin Delivery Assessment

Mechanisms implied in the skin absorption process and the role of cutaneous metabolism are of increasing interest to cosmetics research. In the present paper, the authors demonstrate how an experimental human skin explant model exhibiting great barrier function and metabolic activities can provide an understanding of what happens to cosmetic actives when they are topically applied.

Zeta Potential and Particle Size to Predict Emulsion Stability

Emulsions are popular vehicles in skin care due to their affinity for the skin; however, they are thermodynamically unstable systems. This study investigates zeta potential and particle size distribution as potential screening tools to predict instabilities in emulsion-based cosmetic products, to supplement regular accelerated stability testing.

Analyzing Deposition from Rinse-off Hair Products

The most common approach to determine ingredient deposition on hair is to analyze the treated tresses, but this poses several challenges. Instead, the authors describe a novel approach based on determining the amount of ingredient collected in the rinse water, and back-calculating the amount deposited on hair. Development and validation efforts discussed here use polydimethylsiloxane as a model compound.

Method to Reproduce In vitro Cosmetic Product Photostability Findings

The present article describes a reproducible method for determining the photostability of sunscreen products. This method is based in part on the in vitro determination of the UVA protection factor as proposed by Colipa for the irradiation aspect, and on the spectroscopy of a sunscreen in dilute solution for the absorbance measurement aspect.
