Field of the Invention The present invention relates to compositions comprising extracts from plants of the Combretαceαe family and the use thereof in methods for increasing the uptake of vitamin C into cells. The invention also relates to methods for treating and/or retarding skin ageing, and further relates to a method for lightening skin and modulating hair colour.

Background of the Invention

Skin is the largest body organ and serves as an important environmental interface providing a protective envelope that is crucial for homeostasis. On the other hand, the skin is a major target for toxic insult by a broad spectrum of physical (i.e. UV radiation) and chemical (xenobiotic) agents that are capable of altering its structure and function. Many environmental pollutants are either themselves oxidants or catalyze the production of reactive oxygen species (ROS) directly or indirectly. ROS are believed to activate proliferative and cell survival signaling that can alter apoptotic pathways that may be involved in the pathogenesis of a number of skin disorders including photosensitivity diseases and some types of cutaneous malignancy. ROS act largely by driving several important molecular pathways that play important roles in diverse pathologic processes including ischemia-reperfusion injury, atherosclerosis and inflammatory responses. The skin possesses an array of defence mechanisms that interact with toxins to obviate their deleterious effect. Unfortunately, these homeostatic defences, although highly effective, have limited capacity and can be overwhelmed thereby leading to increased ROS in the skin that can contribute to the development of dermatological diseases and the ageing phenomenon. One approach to preventing or treating these ROS-mediated disorders is based on the administration of various antioxidants in an effort to restore homeostasis. Ascorbic Acid, which is better known as "vitamin C", is one of the most studied and powerful antioxidants occurring in nature. Vitamin C is capable of directly scavenging superoxide, hydroxyl radicals and singlet oxygen as well as reducing H2O2 to water via ascorbate peroxidase reaction. When vitamin C is applied topically onto human skin the following effects can be observed: • Potent antioxidant activity, particularly in regard to protecting skin cells from UV- induced damage; 5 • Low risk of skin sensitization at concentrations up to 10% in the form of vitamin C; • Reduction of transepidermal water loss, thus strengthening skin's barrier response; • Promotion of collagen production and eventually thickening of the dermis; • Reduction of inflammation; o • Reduction in hyperpigmentation; • Improvement of the appearance of sun-damaged skin by strengthening skin's repair mechanisms; • Enhancement of the effectiveness of dermatologist-performed procedures such as peels and microdermabrasion; s Skin aging is a natural unavoidable phenomenon that occurs as a result of both intrinsic factors (stress, hormonal imbalance, tiredness etc.) and extrinsic factors (UV light, pollution, exposure to ROS and cigarette smoke etc.)- Aging leads to changes in the mechanical properties of skin. An imbalance appears between protection and synthesis o systems of the extracellular matrix components and the degradation systems of the extracellular matrix (mainly matrix metallo-proteinases). The imbalance is manifested in a decrease in collagen synthesis that occurs with age together with an increase in the activity of specific metallo-proteinases that degrade connective tissue. The results of this imbalance include thinning of the dermis and a decrease in skin flexibility. The first signs 5 of skin ageing typically appear on specific zones of the face (e.g. around the eyes and lip contours), and expression wrinkles become deeper due to muscular tension. It has been shown that the age related decrease of collagen secretion observed in human skin fibroblast cell cultures is associated with their ability to respond to vitamin C. During collagen synthesis lysine and proline amino acids are hydroxylated so as to o stabilise collagen microfibrils. As a cofactor, vitamin C ensures enzyme protection and promotes collagen synthesis. Because of its crucial role, insufficient amounts of vitamin C lead to decreased collagen synthesis which in turn contributes to skin ageing. There is therefore a need for methods in which the intracellular concentration of vitamin C can be increased thereby enhancing the production of collagen and hence retarding the process of skin ageing. Visible pigmentation of the skin, hair, and eyes depends primarily on the functions of melanocytes, a very minor population of cells that specialise in the synthesis and distribution of the pigmented biopolymer melanin. Melanocytes are derived from precursor cells (called melanoblasts) during embryological development and melanoblasts destined for the skin originate from the neural crest. The accurate migration, distribution and functioning of melanoblasts / melanocytes determine the visible phenotype of organisms ranging from simple fungi to the most complex animal species hi human skin, melanocytes are localised at the dermal/epidermal border in a characteristic regularly dispersed pattern. Each melanocyte at the basal layer of the epidermis is functionally connected to underlying fibroblasts in the dermis and to keratinocytes in the overlying epidermis. Those three types of cells are highly interactive and communicate with each other via secreted factors and their receptors and via cell/cell contacts to regulate the function and phenotype of the skin. Epidermal melanocytes occur at an approximate ratio of 1:10 among basal keratinocytes and distribute the melanin they produce to approximately 40 overlying suprabasal keratinocytes via their elongated dendrites and cell/cell contacts. Although melanocytes and stem cell keratinocytes in the basal layer of the epidermis are very stable populations that proliferate extremely slowly under normal circumstances, keratinocytes in the upper layers of the epidermis proliferate relatively rapidly. That upward pressure carries them toward the surface of the skin along with their ingested melanin to form a critical barrier for the organism against the environment and the many stresses that originate there. Thus it is not the melanin within melanocytes only, but in combination with the pigment in more superficial layers that gives skin its characteristic colour. Skin colour is primarily determined by the amount of melanin present in the surface of the skin. Within melanocytes melanin is bound to a protein matrix to form melanosomes. In melanosomes, tyrosinase converts tyrosine to eumelanin or pheomelanin through the pathways of melanin biosynthesis. By blocking the pathways at various points, skin depigmentation agents can inhibit melanin biosynthesis and can be used to treat local hyperpigmention or spots which are caused by a local increase in melanin synthesis or uneven distribution. Because vitamin C exerts an in vivo inhibitory action on melanin synthesis and does not lead to any side effects it is useful as a whitening/lightening agent for the skin. However, free vitamin C tends to be less resistant to oxidative conditions than other vitamins and is therefore more easily decomposed. Accordingly, there is a need for methods in which the intracellular concentration of vitamin C can be increased so as to decrease the production of melanin, thereby resulting in a lightening, brightening and/or whitening of skin colour. Follicular pigmentation is under complex genetic control, as determined from studies in mostly murine models. In the mouse, coat color is regulated by more than 150 alleles at over 90 loci. Protein products of these loci have a wide array of cellular targets, and functions, acting as enzymes, structural proteins, transcriptional regulators, transporters, or receptors and their ligands. This organization allows control of melanin synthesis at all levels: cellular (follicular melanocyte), organ (hair follicle), and developmental steps (neural crest, melanoblast migration, targeting to skin, differentiation to melanocytes, and melanocyte proliferation and survival). In the adult hair follicle pigmentation results from precise sequential interactions between follicular melanocytes, matrix keratinocytes and dermal papilla (DP) fibroblasts. It involves the melanogenic activity of follicular melanocytes, the transfer of their product, melanin granules, into cortical and medullary keratinocytes and the formation of pigmented hair shafts. Hair is actively pigmented only during the anagen stage of the hair cycle to which the melanogenic activity of follicular melanocytes is stringently coupled; melanin formation is switched-off in catagen remaining absent through telogen. Pigmentation lags behind the expression of melanogenesis-related proteins (MRP) that in turn exhibits a time-frame restricted, differential pattern of transcription, translation and functional activity during the development of anagen follicles. Thus, follicular melanogenesis (FM) is characteristically cyclic in nature as opposed to the continuous melanogenesis of epidermal pigmentation. Melanin synthesis and pigment transfer to bulb keratinocytes are to a large extent controlled by signals intrinsic to skin and represented by products of keratinocytes, immunocytes, fibroblasts, and endothelial cells. Melanocytes can reciprocally affect the surrounding cells, e.g., by direct melanosome transfer (to keratinocytes), or by production and secretion of functional regulators. Thus, anagen-coupled melanogenesis and its regulatory network control hair growth and pigmentation, leaving the pigmented hair shaft as a visible, long-lived record of complex epithelial-mesenchymal-neuroectodermal interactions. The melanocyte component of this tissue interactive cell system in hair follicles is more sensitive to ageing influences than melanocytes in the epidermis, resulting in hair graying. This likely reflects differences in the epidermal and follicular microenvironments. Hair colour is mainly determined by the amount and composition of melanin present in the hair bulb melanocytes. Within melanocytes, melanin is bound to a protein matrix to form melanosomes. In the melanosomes, tyrosinase converts tyrosine to eumelanin or pheomelanin through the pathways of melanin biosynthesis. By blocking the pathways at various points, hair depigmentation agents can inhibit melanin biosynthesis, and can be used to gently and biologically to alter hair colour. Because vitamin C exerts an in vivo inhibitory action on melanin synthesis and does not lead to any side effects it is useful as a whitening/lightening agent for hair. However, free vitamin C tends to be less resistant to oxidative conditions than other vitamins and is therefore more easily decomposed. Accordingly, there is also a need for methods in which the intracellular concentration of vitamin C in hairbulb-located melanocytes can be increased, thereby decreasing the amount of melanin deposited onto emerging hair fibres so as to decrease the colouration of human hair. Surprisingly, the present inventor has discovered that the uptake of vitamin C into cells, either in its free form, or in the form of a derivative, can be increased using an extract from a member of the Combretaceae family of plants.

Examples

Example 1 - Stimulation of Vitamin C incorporation into human dermal fibroblasts

Human fibroblasts from a person 40 years of age are treated with Anogeissus extract at different concentrations and incubated for a period of 48 hours. After addition of C 4ascorbic acid solution and an incubation period of 6 hours, the cells are lyzed and radioactivity is measured by scintillation. At a concentration of 5 µg/ml of Anogeissus extract, vitamin C incorporation into the fibroblasts was increased by about 40%. By increasing vitamin C uptake into the fibroblasts, Anogeissus extract helps to stimulate collagen synthesis.
