Testing Tactics in Skin: Evaluating Radiance and Texture

Hydrated, even-toned skin with a natural glow, all indicators of health, has gained popularity in the last decade. This article explores the meaning of skin radiance, its relationship to texture and various ways to measure this desired attribute.

For desirable hair styles, both stiffness and flexibility are necessary – but the two properties are generally considered incompatible.

Isomalto-oligosaccharides Naturally Balance ‘Stiffness’ with Flexibility for Hair Styling Benefits

Transdermal microneedle patches enable active ingredients to bypass the slow diffusional process across the stratum corneum’s barrier to reach directly into the deeper skin layers.

Empowering Skin’s Resilience with CefiraProtect CLR™

CLR introduces CefiraProtect CLR™, the daily companion for youthful skin. Derived from Lactobacillus kefiranofaciens, this innovative active ingredient supports skin in maintaining its oxidative balance and enhancing its self-defense mechanisms.

In evaluating how different solvents may affect the rheology of personal care formulas, it is helpful to consider that different formulation types have distinct relationships between viscosity and elasticity depending on the factors generating their elastic properties.

How Natural Butylene Glycol Advances Market and Rheology Dynamics

Demand for sustainable ingredients in cosmetics and personal care is well-known. Here, a sustainable natural butylene glycol is described to advance this trend and its effects on viscosity and elasticity are assessed in five test formulas.

Like other markets, efficacy testing, including for cosmetics, is projected to have a substantial increase in revenue by 2027, largely due to pharmaceuticals and biotechnology making constant advancements in relation to public views and the pandemic.

Efficacy Testing Market Worth $423 Million by 2027

Like other markets, efficacy testing, including for cosmetics, is projected to substantially increase in revenue by 2027, largely due to pharmaceuticals and biotechnology making constant advancements in relation to public views and the pandemic.

The authors believe that adding the properties of a wide range of commercial sunscreens to the system database will increase the rate of appropriate sunscreen usage by customers.

AmorePacific, Hanyang Univ. Dynamically Visualize UV Dose on SPF-protected Skin

Work by AmorePacific and Hanyang University, Seoul, published in Skin Research & Technology, reveals a dynamic approach to visualize UV dose based on MED, weather, outdoor activity, etc., on SPF-protected skin.

To prevent and repair UV-induced skin damage, a sustainable ingredient was developed from Sargassum vulgare, a brown seaweed that naturally evolved phlorotannins to defend against UV damage. The algae was fermented using a proprietary yeast to enrich this bioactive content; the resulting ingredient was tested as described here for skin benefits.

Brown Seaweed Ferment Propagates UV Damage Protection for Skin

To prevent and repair UV-induced skin damage, a sustainable ingredient was developed from Sargassum vulgare, a brown seaweed that naturally evolved phlorotannins to defend against UV damage.

The model accurately predicted skin permeability and the speed of the UHPLC method could classify it as a high-throughput approach.

Test Model Developed to Predict Skin Permeability of Compounds

A test model published in the Journal of Chromatography A uses retention on octadecyl, cholesterol-bonded and immobilized artificial membrane columns to accurately predict the skin permeability of compounds.

The Dermial ingredient, a hyaluronic acid matrix ingredient for skin and beauty, delivers better results for skin health over standard hyaluronic acid (HA) in nutricosmetic form.

Bioiberica’s Dermial Nutricosmetic Outperforms Extracted and Fermented HAs

A pre-clinical in vitro study showed the Dermial hyaluronic acid (HA) matrix nutricosmetic increased type I collagen production by almost half. According to Bioiberica, this has not been seen with standard extracted or fermented HAs.

For multifunctional products such as moisturizing hand sanitizers, the sanitizer claim requires a significant reduction (2-3 log) of a microorganism population while the moisturizer claim requires data showing an increase in skin moisture.

Testing the Safety and Efficacy of Multifunctional Personal Care Products, A Primer

Multifunctional products may offer solutions to consumer challenges but as the needs of consumers grow more complex, so do their safety and efficacy testing. This article provides a primer on these considerations.

Silicones are widely used as binders in pressed powders but growing consumer skepticism has prompted the use of alternatives. The aim of this study was to assess the efficacy of three plant-derived natural binders in obtaining optimal pressed powders, using dimethicone as a standard.
