Skin care compositions comprising Aphanothece sacrum exopolysaccharide extract help the skin penetration of peptide compounds contained therein.

The use of long-chain alkenones to impart desired characteristics in personal care compositions for topical applications is described. The preparation of mixtures long-chain alkenones and synthetic derivatives thereof is presented. Examples of compositions include abrasive soaps, with alkenones serving as natural exfoliating agents. Alkenones and their derivatives can serve as emollients, occlusive agents, encapsulating agents, stabilizing agents, binding agents, thickening agents, surfactants, and antimicrobials.

The present invention provides a seaweed-based powder. The seaweed-based powder of the present invention has the advantage that it does not deleteriously impact, or it impacts to a lesser extent, the desired colour of a product containing thereof. In addition, the seaweed-based powder of the present invention has the capacity to produce gels having an optimum strength for the intended application. In particular, the invention provides a seaweed-based powder having an aerated bulk density (ABD) of at least 0.20 and a CIELAB L* value of at least 70.

The present invention relates generally to methods of use and compositions useful to reduce dark spots, age spots, and/or unwanted pigmentation of skin. The composition includes a combination of niacinamide, phytic acid, Rosmarinus officinalis leaf extract, Chondrus crispus extract, and a combination of Saxifraga sarmentosa extract, Carica papaya (papaya) fruit extract, and Psidium guajava (guava) fruit extract. The composition is effective to reduce dark spots, age spots, and/or unwanted pigmentation of skin. The composition is effective to inhibit tyrosinase and/or Peroxisome Proliferator-Activated Receptor Gamma (PPAR-γ) activity. The composition is further effective to reduce melanin content in skin, particularly dark skin, in some instances by at least 30%.

A method for decreasing formation of one or more chemiexcitation-induced dark cyclobutane pyrimidine dimers (dCPDs) in a cell or DNA molecule in a subject, who has been exposed to UV radiation, is provided. The method comprises administering to the subject an effective amount of a dCPD quencher within 8 hours after the exposure. The dCPD quencher is selected from the group consisting of ellagic acid, Porphyra Umbilicalis Extract (including Porphyra Umbilicalis Extract (and) Sodium Lactate (and) Lecithin), mycosporine-like amino acids (MAAs) and synthetic analogues thereof, Scutellaria Baicalensis Root Extract, Chrysanthemum Morifolium Leaf Extract, ferulic acid, fused-ring cyanoacrylates, curcumin, epigallocatechin gallate, Scutellaria Baicalensis Root Extract (and) Acacia Catechu Wood Extract, sorbic acid, Polygonum Cuspidatum Root Extract, Acacia Catechu Extract, dipicolinic acid, squalene, Lonicera Japonica (Honeysuckle) Flower Extract, beta-carotene and combinations thereof. The dCPD quencher may be administered to the subject in the absence of UV radiation.
