Technical Field The present invention relates to methods of regulating the condition of mammalian keratinous tissue using defined phytosterols wherein the methods include, a) thickening skin and preventmg, retarding, and/or treating atrophy m mammalian skin, b) preventing, retarding, and/or treating the appearance of dark, under-eye circles and puffy eyes, c) preventing, retarding, and/or treating sallowness of mammalian skm, d) preventing and/or retarding tanning of mammalian skm, e) desquamating, exfoliating, and/or increasing turnover of mammalian skin, f) regulating and/or reducing the size of pores in mammalian skin, g) regulating the oily and/or shmy appearance of mammalian skin, h) preventing, retarding, and/or treating post-inflammatory hyperpigmentation, and l) preventing and/or treating the appearance of cellulite m mammalian skm These methods are accomplished via the topical application of compositions containing specific phytosterols to the skm of a mammal needmg such treatments. Background of the Invention Currently, there are a number of personal care products that are available to consumers, which are directed toward improving the health and physical appearance of keratmous tissues such as the skin, hair, and nails. The majority of these products are directed to delaying, minimizing or even eliminating skm wrinkling and other histological changes typically associated with the aging of skm or environmental damage to human skin. Mammalian keratinous tissue, particularly human skin, is subjected to a variety of msults by both extrinsic and intrinsic factors Such extrinsic factors include ultraviolet radiation, environmental pollution, wmd, heat, infrared radiation, low humidity, harsh surfactants, abrasives, etc. Intrinsic factors, on the other hand, include chronological aging and other biochemical changes from within the skm Whether extrinsic or intrinsic, these factors result in visible signs of skin damage Typical skin damage includes thinning of the skin, which occurs naturally as one ages With such thinning, there is a reduction in the cells and blood vessels that supply the skin as well as a flattening of the dermal-epidermal junction that results in weaker mechanical resistance of this junction. See, for example, Oikaπnen, "The Agmg of Skin Chronoagmg Versus Photoagmg," Photodermatol Photoimmunol Photomed , vol 7, pp. 3-4, 1990 Other damage or changes seen in agmg or damaged skin includes sallowness, sagging, dark, under-eye circles, puffy eyes, enlarged pores, diminished rate of turnover, and abnormal desquamation or exfoliation Additional damage incurred as a result of both external and internal factors mcludes visible dead skm (1 e , flaking, scaling, dryness) Therefore, there is a need for products and methods that seek to remedy these keratmous tissue conditions such that the conditions of keratinous tissues are regulated Without being limited by theory, it has been found that certain phytosterols can stabilize cellular and extracellular components of keratinous tissue, particularly the outer cell membranes as well as membranes of various organelles The phytosterol treated cells become stronger, more resistant, and are able to withstand higher levels of the above-described insults Consequently, Applicants have surprisingly found that topical compositions that contain specific phytosterols may be used to provide prophylactic as well as therapeutic treatments for keratinous tissue conditions For instance, Applicants have found that such compositions may be useful for treating atrophy of the skin as well as sallowness, spider vessels, dark, under-eye circles, puffy eyes, promoting skin desquamation, exfoliation, and/or turnover, regulating and/or reducing pore size appearance, preventmg/retarding tanmng, regulating oily/shiny appearance, preventing/retarding post-mflammatory hyperpigmentation m mammalian skm, and preventing and/or treating the appearance of cellulite in mammalian skin Summary of the Invention The present invention relates to methods for regulating the condition of mammalian keratmous tissue wherein the methods each comprise the step of topically applying to the keratinous tissue of a mammal needing such treatment, a safe and effective amount of a composition compπsmg a) a safe and effective amount of one or more phytosterols selected from the group consistmg of β- sitosterol, campesterol, brassicasterol, Δ5-avennasterol, lupenol, α-spmasterol, stigmasterol, their deπvatives, and combinations thereof, and b) a dermatologically acceptable carrier for the phytosterol In additional embodiments, the above composition is suitable for thickening skin and preventing, retarding, and/or treating atrophy of mammalian skin, preventing, retarding, and/or treating the appearance of dark, under-eye circles and puffy eyes, preventmg, retarding, and/or treating sallowness of mammalian skm, preventing and/or retarding tanning of mammalian skin, desquamating, exfoliating, or mcreasing the turnover of mammalian skin, regulating and/or reducing the size of pores in mammalian skm, regulating oily/shmy appearance of mammalian skin, preventing, retardmg, and/or treatmg post-mflammatory hyperpigmentation, and preventmg and/or treating the appearance of cellulite in mammalian skin Detailed Description of the Invention All percentages and ratios used herein are by weight of the total composition and all measurements made are at 25 C, unless otherwise designated The compositions of the present invention can comprise, consist essentially of, or consist of, the essential components as well as optional ingredients described herein As used herein, "consisting essentially of means that the composition or component may include additional ingredients, but only if the additional ingredients do not materially alter the basic and novel characteristics of the claimed compositions or methods All publications cited herem are hereby incorporated by reference in their entirety. The term "keratmous tissue," as used herem, refers to keratm-containing layers disposed as the outermost protective covering of mammals which includes, but is not limited to, skin, hair, toenails, fingernails, cuticles, hooves, etc . The term "topical application", as used herein, means to apply or spread the compositions of the present invention onto the surface of the keratinous tissue. The term "dermatologically acceptable," as used herein, means that the compositions or components thereof so described are suitable for use in contact with human keratinous tissue without undue toxicity, incompatibility, instability, allergic response, and the like. The term "safe and effective amount" as used herein means an amount of a compound or composition sufficient to significantly induce a positive benefit, preferably a positive keratinous tissue appearance or feel benefit, including independently or in combinations the benefits disclosed herein, but low enough to avoid serious side effects, i.e., to provide a reasonable benefit to risk ratio, within the scope of sound judgment of the skilled artisan. The term "post-inflammatory hyperpigmentation" as used herein refers to the changes in melanin content as a response to an inflammatory event (e.g , acne, scratch, insect sting, sunburn, etc), especially in dark skm subjects. The terms "desquamation, exfoliation, and/or increasing turnover" as used herein mean the removal of the upper layers of the stratum corneum (compπsmg the horny and granular layers) Without intendmg to be limited by theory, it is believed that these benefits may be accomplished via chemical and physical means that remove these layers from the top down Additionally, it is possible to elicit exfoliation via a biological means that drives the turnover of the epidermal layers from the basal layers upwards. It is believed that this involves the process of keratinocyte proliferation as well as induction of differentiation. The latter leads to an elevation in keratinization levels as well, which ultimately lead to a reorganization of the upper epidermal layers that compπse the stratum corneum and stratum granular layers. The terms "oily and/or shiny appearance" as used herem mean the glossy look mammalian skin tends to exhibit upon the excretion of oil, sebum, and/or sweat from the respective source gland. The compositions of the present invention are useful for topical application and for regulating keratinous tissue condition Regulation of keratinous tissue condition, especially human skm condition, is often required due to conditions that may be induced or caused by factors internal and/or external to the body. For instance, "regulating skin condition" includes prophylactically regulating and/or therapeutically regulating skin condition, and may involve one or more of the following benefits: thickening of skm (i.e., building the epidermis and/or dermis layers of the skm and or the subcutaeous layers such as fat and muscle and where applicable the keratinous layers of the nail and hair shaft) to reduce skm atrophy, increasing the convolution of the dermal-epidermal border, non-melanin skin discoloration such as under eye circles, blotching (e g , uneven red coloration due to, e g , rosacea) (hereinafter referred to as "red blotchiness"), sallowness (pale color), discoloration caused by telangiectasia or spider vessels As used herein, prophylactically regulating skin condition mcludes delaymg, minimizing and/or preventing visible and/or tactile discontinuities in skm (e g , texture irregularities in the skm which may be detected visually or by feel) As used herein, therapeutically regulating skin condition includes ameliorating, e g , diminishing, minimizing and or effacing, discontinuities m skm Regulating skm condition involves improving skm appearance and/or feel As used herein, "regulating skin condition" is intended to include regulation of such signs irrespective of the mechanism of oπgm The compositions of the present invention, including the essential and optional components thereof, are described in detail hereinafter Phytosterol The topical compositions of the present invention comprise a safe and effective amount of one or more phytosterols selected
