Formulations such as serums to treat skin discoloration via a multi-modal approach are provided in some embodiments in which select ingredients work together to effectively brighten skin and treat hyperpigmentation.

Methods for obtaining an aqueous extract of a microalgae Dunaliella salina cultivated in the absence of light in a culture medium of a yeast extract, sugar and salt include solubilising a yeast extract in water then adding sugar and salt. After solubilisation of the salt and at a pH between 5 and 8, the microalgae Dunaliella salina is added with stirring, in darkness and at room temperature, for a fermentation period of at least 12 hours. After the fermentation period, grinding and filtering are performed to separate a soluble aqueous raw extract to which salt is added. This extract undergoes sterilising filtration with a porosity threshold of less than or equal to 0.2 μm and has a pH between 3.5 and 4.5. The extract obtained by the method, compositions incorporating the extract, and methods of skincare, scalp care and skin appendage care using such compositions are also disclosed.

The present invention relates to a novel violaxanthin-overproducing strain of Chlorella vulgaris and a method of producing violaxanthin therefrom. The inventors have developed a strain that produces violaxanthin at a significantly higher level than a wild-type strain by inducing a random chemical mutation in a Chlorella vulgaris strain to, and then as a result of analysis, confirmed that the strain produces violaxanthin up to 0.41% based on dry weight, which reaches the highest level that is possible to be produced in microalgae. Furthermore, as a method of effectively extracting a carotenoid pigment containing violaxanthin from the strain was established, since the strain and the developed pigment extraction method according to the present invention allow effective production and separation of violaxanthin, the strain is expected to increase commercial applications such as cosmetics, health functional foods and feed.

A spray-on film forming composition is designed to work with another topical preparation, such as a conventional cosmetic foundation or skincare product. The film forming composition is in direct contact with the cosmetic or skincare product. The spray-on film forming composition may be applied underneath a topical preparation (as a primer), on top of a topical preparation (as a mask), or both, depending on the benefit conferred. The spray-on film forming compositions of the invention are able to improve wearability and removability, increase shine, and deliver active ingredients. They are very clear, flexible and comfortable.

A cosmetic composition is disclosed for applying to skin. The composition includes a liquid and dispersed in the liquid: any amount or form of fucoidan, any amount or form of beta glucan; and any amount of a marine extract. When the cosmetic composition is applied to the skin, the appearance of the skin is improved.
