This invention describes a method of making a layered personal care composition comprising the steps of: a) providing a first layer and a second layer that each are fluid at elevated temperature, solid at ambient temperature, and visually distinctive from each other; b) providing the first and second layers in fluid state at an elevated temperature in isolated vessels; c) separately dispensing the first layer by a first nozzle and the second layer by a second nozzle while maintaining the elevated temperature, into a same package having a circle plan view shape—wherein the positions of the nozzles, relative to the center of the package, are maintained during dispensing, and wherein the middle point of the nozzles do not coincide with the Z axis running vertically through the center of the package; and d) cooling the dispensed composition for solidifying in the package.

By providing multiple layers of compositions in the same package, a visually attractive product is produced. The present invention is suitable for any personal care composition that is fluid in elevated temperatures and solid at ambient temperatures, such as cosmetic foundation, sunscreen, blusher, eye shadow, eyebrow cake, mascara cake, lipstick, lip balm, antiperspirant stick, dermal pharmaceutical ointment, hair styling/conditioning wax, and others.

Methods for assaying MC1R variants and mitochondrial markers in skin samples
US Patent Application 20110045471
Publication date: Feb. 24, 2011
Assignee: Genesis Genomics Inc.

The disclosed patent relates to methods for predicting, diagnosing and monitoring skin states and skin diseases. The methods combine non-invasive skin collection techniques with one or more assays for determining mitochondrial DNA aberrations and Melanocortin 1 Receptor (MC1R) variants, thereby providing a comprehensive tool for identifying, predicting and/or monitoring photo-aging, UV radiation damage or skin disease. The methods of the invention may also be effective in screening for new therapeutic agents, skin care products and treatment regimes, and may also be useful for monitoring the response of a subject to a preventative or therapeutic treatment.
