Abstract

Compositions and methods for lightening skin are provided. A method for lightening skin may include the step of identifying skin where lightening or whitening is desired and topically applying to the skin a composition including (a) a skin lightening agent comprising a canola extract and (b) a cosmetically acceptable carrier. A method for treating hyperpigmentation may include the step of identifying skin containing areas of hyperpigmentation and topically applying to the skin a composition including (a) a canola extract and (b) a cosmetically acceptable carrier.

Description

METHODS OF SKIN WHITENING BY USE OF CANOLA EXTRACTS
FIELD OF THE INVENTION
The present invention relates generally to compositions of canola extracts containing high levels of phenolic acids and their methods of use to whiten skin.
BACKGROUND
In humans, melanin is the primary determinant of skin color. In the skin, specialized cells found in the basal layer of the dermis called melanocytes, produce melanin. Human possess similar concentrations of melanocytes in their skin, but present different concentrations of skin melanin based on their ethnicity.
Melanin plays an important biological role as a photoprotectant because it absorbs harmful UV radiation and transforms that energy into harmless heat. This property enables melanin to dissipate more than 99.9% of the absorbed UV radiation as heat.
Melanogenesis, or increased production of melanin in human skin, is stimulated by UVB-radiation to produce what is commonly known as a tan. Although a tan appearance is desired by some people in various cultures, some cultures desire a lighter skin appearance. Further, melanin pigment disorders are perceived as cosmetic flaws. Examples of these local hyperpigmentations would be: freckles, melasma, chloasma, post-inflammatory hyperpigmentation, liver spots and many more. It is common to all forms of hyperpigmentation that a disturbance in the melanogenesis arises.
Various strategies have therefore been developed to reduce the pigmentation of the skin. One of the most often used skin and hair lighteners is hydroquinone or the hydroquinone glycoside of arbutin. However, these compounds have a cytotoxic effect on melanocytes and have an irritative effect on the skin. Another option is the inhibition of the synthesis of melanin by inhibiting the pacemaker enzyme tyrosinase. For this, the substances kojic acid and derivatives of kojic acid such as e.g. kojic acid dipalmitate kojic acid, azelaic acid, oxyresveratrol, linolenic acid, vitamin C and derivatives of ascorbic acid such as, for example, ascorbyl phosphate or ascorbyl palmitate, inter alia, are used.
However, these substances have a high sensitizing potential, cause contact allergies, exhibit inadequate chemical stability in cosmetic formulations, or have only an unsatisfactory effect on the skin.
Moreover, strategies are also known which prevent the transfer of the melanin from the melanocytes into the surrounding keratinocytes. Thus, protease inhibitors are described which inhibit the PAR2 receptor on the surface of the keratinocytes and as a result reduce the
