Ultramarine blue pigment enhances foundations for North Asian complexions – L’Oréal study

Ultramarine blue pigment can fully replace black pigments in foundations and provide superior cosmetic benefits for North Asian complexions, suggests a new study by Japan-based L’Oréal researchers.

While the use of ultramarine blue as a pigment is well-documented, the researchers hoped to study its optical properties.

They concluded that the foundation formulated with ultramarine blue pigment showed “superiority” with the following effects: improved coverage, improved skin uniformity, and concealment of skin wrinkles and blotches.

Kao discovers unique scents to advance fragrance innovation

Japanese beauty giant Kao is looking to develop new products based on distinct orchid scents, after discovering hundreds of options that are yet to be harnessed for commercial applications.

According to the findings, 887 different aroma compounds were identified in orchid flower fragrances, which indicate that orchid scents are significantly more diverse than those of other plants.

In addition, 38% of the aroma compounds were present in only one species of orchid. This means that a large number of orchid species have unique and individual scents.


Singapore start-up targets personalised cosmetics opportunities with ‘organ-on-chip’ tech

Singapore spin-off REVIVO BioSystems is targeting personalised cosmetics opportunities using its tech.

Founded in 2019, REVIVO BioSystems provides technology and services for ex-vivo and in-vitro testing of chemicals, ingredients, cosmetic formulations, and therapeutics.

Since then, he said it had evolved from ‘skin-on-a-chip’ to ‘organ-on-chip’.

The microfluidic chips can now be produced by injection moulding, which provides for “a very rapid and cost-effective way of fabrication.​”

Shinsegae touts regenerative cosmetics using microalgae-derived exosome tech

Shinsegae International is developing regenerative cosmetics using microalgae-derived exosome technology based on its joint research with Sungkyunkwan University (SKKU).

The firm said it was applying this technology to its cosmetic brands, Yunjac and VIDIVICI. These new products can be expected to hit the market sometime this year.

The research focused on finding a replacement for human-derived exosomes, which has gained interest in skin care areas such as wound-healing, and discovered a replacement within a microalgae species, Euglena gracilis.

Dead Sea water has ‘great potential’ for cosmetics applications, but challenges remain – Review

Dead Sea water (DSW) has considerable potential in cosmetics application, but compatibility issues in formulations need to be resolved before it can be safely applied, say researchers.

Multiple studies also discovered DSW’s efficacy in skin moisturisation, anti-inflammation, skin barrier repair, and anti-pollution.

Though DSW boasts "great potential" for cosmetics application, there are still challenges to overcome.

Firstly, environmental factors, human intervention and changes in biodiversity could aggravate the exhaustion of Dead Sea resources.
