Dove Experiment Shows Beauty is Mind Over Matter

A social experiment conducted by Unilever brand Dove revealed that 80% of women feel anxious about the way they look. The study also highlighted how the right state of mind can unlock a feeling of beauty in women.

Sandblasting to Improve the Reproducibility of In vitro Sunscreen Evaluation

SPF test results from substrates treated using a traditional sandblasting technique are compared with those from substrates treated using a new process. Based on the topographic control of 10 batches and 34 sunscreen evaluations, the authors concluded the new process had better topographic reproducibility, consequently improving the SPF repeatability and reproducibility in vitro.

Collagens I and III, and Elastin Activation for Anti-aging

As an alternative to semi-invasive facial rejuvenation techniques, the authors developed an active ingredient to reactivate senescent fibroblasts by stimulating metabolic pathways for collagens I and III, and elastin. The biological activity of the resulting ingredient is investigated here using in vitro models, ex vivo explants and human volunteers.

Measuring Hair Strength, Part II: Fiber Breakage

In the mechanical testing world, the tendency for materials to fail under a repeated stimulus is termed fatigue testing, and this article discusses this topic in relation to hair breakage. It will be shown that this alternative testing approach provides considerable insight into the cause of hair breakage, and subsequently allows for the identification of strategies for its minimization; it will also be demonstrated how learning this provides the underlying theory by which anti-breakage and even “strengthening” claims are crafted.

Liverpool Student Develops Alternative to Draize for Testing Mascara Irritation

Researchers at the University of Liverpool have developed a testing method alternative to the Draize test for mascara eye irritation using protozoa rather than animals. In addition to the new method not using rabbits, it was found to be cheaper and more reliable.

Tech Edge: Optical Tools to Examine the Structure of Cosmetic Products

To monitor or anticipate what can happen in the creation of a cosmetic product when components are combined and as time passes is no trivial task especially when compounded with the psychophysical needs for the product to fit a specific concept and to spread, feel, pour and appear elegant.

Influence of pH on the Preservative Boosting Effect of Chelating Agents

A system based on phenoxyethanol and ethylhexylglycerin (euxyl® PE 9010) from Schülke & Mayr is described here to boost the efficacy of preservatives. To substantiate its efficacy, the effects of the system were checked at pH levels of both 7.0 and 5.0.

CeeTox Inches Closer to Validating Non-Animal Skin Allergy Assay

CeeTox has reported positive results from the recent phase of a PETA-funded validation study performed by the Flemish Institute for Technological Research (VITO)’s Applied BIO & Molecular Systems (ABS) team.

C + K Devices Used in Space to Quantify Skin Aging

Skin measurement devices from Courage + Khazaka Devices have been used for the second time on the International Space Station (ISS) to verify skin aging in space
