AI Technical Summary

Benefits of technology

The present invention provides compositions that can be used in skin treatment applications. These compositions contain kakadu plum extract and / or acai berry extract, which have been found to have beneficial effects on skin when used alone or in combination. The compositions can be formulated into various types of skincare products, such as cosmetic compositions, anti-aging products, cleansing products, and moisturizing products. The compositions can also have a desired oxygen radical absorbance capacity (ORAC) value. Additionally, the compositions can include other ingredients such as vitamins, minerals, essential fatty acids, amino acids, flavonoids, and proteins. The technical effects of the invention include improved skin appearance, reduced skin damage, and improved skin health.

Problems solved by technology

With ageing, chronic exposure to adverse environmental factors, or malnutrition, the visual appearance, physical properties, and physiological functions of skin can change in ways that are considered visually undesirable.

Bioefficacy of Kakadu Plum Extract as an Anti-Oxidant

[0090]The ability of kakadu plum extract to act as an anti-oxidant was evaluted in terms of its ability to (1) reduce existing internal oxidation in cells; and (2) reduce external oxidative damage to cells.

[0091]Peroxide Assay: Cellular peroxides are measured flow cytometrically using the peroxide-specific dye, 2′,7′-dichlorofluorescein diacetate (DCFH-DA). DCFH-DA is initially non-fluorescent and is rapidly concentrated within living cells by an enzyme-dependent process. Following modification by cellular peroxides, this dye exhibits an intense green fluorescence when excited by laser light. Basal peroxide production, generated by normal cellular metabolism, will induce a gradual development of low levels of peroxide-specific cellular fluorescence. As such, a measurement of this fluorescence without any treatment can act as a negative control for comparative purposes. Furthermore, extracellular peroxides (i.e., H2O2, added exogen...

Collagen Production in Human Fibroblast Dermal Cells in the Presence of Kakadu Plum Extract

[0093]The ability of kakadu plum extract to increase collagen production in human fibroblast dermal cells was studied.

[0094]Collagen production protocol: Normal human dermal fibroblast (NHDF) cells were grown to subconfluence from a frozen vial in tissue culture flasks (T25's). Two confluent T25's were trypsinized, washed, resuspended to 16 mls and seeded heavily into a 96 well plate (200 μl / well) (Columns 4-12 only). Cells were allowed to grow overnight or until the cells reached 100% confluence. Upon reaching confluence, the spent media was aspirated and 200 μl of fresh media with or without samples of interest (in triplicate) were added. The liquid extract in FIG. 2 is 1.0% (20 μl of 100× stock) and 0.1% (2 μl of 100× stock) kakadu extract and was diluted into a final volume of 200 μl NHDF growth medium (note that the liquid extract is listed at 20-30% W / W with 10-20% denatured alcohol and ...
