DETAILED DESCRIPTION
[0018] The terms used in this specification generally have their ordinary meanings in the art, within the context of the invention, and in the specific context where each term is used.
Certain terms are discussed below, or elsewhere in the specification, to provide additional guidance to the practitioner in describing the compounds, compositions, and methods of the invention and how to make and use them. Moreover, it will be appreciated that the same thing can be said in more than one way. Consequently, alternative language and synonyms may be used for any one or more of the terms discussed herein, nor is any special significance to be placed upon whether or not a term is elaborated or discussed herein. The use of examples anywhere in this specification, including examples of any terms discussed herein, is illustrative only, and in no way limits the scope and meaning of the invention or of any exemplified term. Likewise, the invention is not limited to the examples presented.
[0019] The present disclosure is directed to a composition comprising a probiotic and an antioxidant in a probiotic/antioxidant wt/wt ratio of about 0.1/2.5 to about 1.0/95 and wherein said probiotic/antioxidant composition act synergistically as an inhibitor at a concentration of < about 10 pg/mL and is lost at concentrations of > about 10 pg/mL.
[0020] It is well established in the dermatological literature that various pathways are responsible for inflammatory human skin, degradation of food product, and aging. These pathways are triggered by any number of perturbations (UV light, chemical irritants, mechanical trauma). The processes are often oxidative in nature, and scientific literature has demonstrated that topical and/or systemic antioxidants are effective at inhibiting these oxidative steps.
[0021] A sampling of pathways responsible for inflammation, aging, and degradation follow.
100221 "Adhesion Pathway" is the pathway by which cells adhere to blood vessels and other skin tissues when injury or immune challenge has occurred.
[0023] "Chemotaxis Pathway" means the pathway where chemical signals cause inflammatory cells to migrate toward a site, such as skin or tissue, where immune challenge has occurred. If such inflammatory cells are prevented from migrating to the site of immune challenge the resulting damage that such cells provide to skin or tissues can be mitigated.
[0024] "Collagenase Pathway" means the pathway by which the enzyme collagenase breaks down the peptide bonds in collagen and destroys extracellular structures such as those found in bacteria or infiltrating lymphocytes at the sites of inflammation. The collagenases released will cause tissue damage by breaking down collagen fibrils in the extra cellular matrix.
[0025] "COX Pathway" means the pathway by which the cyclooxygenase (COX) enzyme (including but not limited to cyclooxygenase-2 or COX-2) converts arachidonic acid and/or other fatty acids to prostaglandin or prostanoids which ultimately contributes to inflammation or pain in immune challenged tissue such as skin.
[0026] "PDE Pathway" means that pathway by which PDE (phosphodiesterase) including phosphodiesterase-4 (PDE4) cleaves the phosphodiester bond that may be found in proteins and other molecules present in bacteria, viruses, and other molecules that contribute to skin inflammation. PDE4, in particular; is a member of a family of enzymes that catalyze the degradation of CAMP to the corresponding 5'-nucleotide monophosphate.
PDE4 is abundant and is the major regulator of CAMP metabolism in almost every pro-inflammatory and immune cell. PDE4 inhibitors exert their anti-inflammatory effects by inhibiting the breakdown of cAMP (leading to an increased concentration of CAMP in immune cells) which will ultimately lead to a decrease in the production and release of pro-inflammatory cytokines such as Interleukin 1-.beta. (IL-1 .beta.) and Tumor Necrosis Factor .alpha. (TNF.alpha.).
[0027] "Elastase Pathway" means the pathway by which the enzyme elastase degrades proteins including elastin that are found in bacteria and other molecules.
When the Elastase Pathway is triggered the cascade of reactions contributes to inflammation or pain in immune challenged tissue such as skin. Elastase, a peptidase released from infiltrating neutrophils at the site of inflammation, will break down elastin, an elastic fiber that, together with collagen, helps determine the mechanical properties of skin and other tissues.
Inhibition of elastase will minimize the damage that may be caused by infiltrating neutrophils which in turn will help preserve the integrity of the extra cellular matrix.
[0028] "Histamine Pathway" means the pathway where the amino acid histidine is decarboxylated to form histamine in response to immune challenge or other injury to tissue or skin. Histamine is a biogenic amine that is synthesized and stored in mast cells which reside primarily in the skin. Histamine plays a major role in the initiation of the inflammatory cascade. Upon stimulation, mast cells (and basophils) will release their stored histamine which will bind to H1 receptors on a vanety of cells (including smooth muscle cells and endothelial cells in blood vessels) exerting its biologic effects. These effects include vasodilation, separation of endothelial cells (causing abnormal vascular permeability), pain and itching. Inhibition of histamine release provides amelioration from many of the adverse effects of inflammation.

[0029] "Histamine Receptor Pathway" means that pathway by which cellular receptors for histamine are activated to bind to histamine, which in turn contributes to the inflammatory condition of tissues or skin.
[0030] "LO Pathway" means the pathway by which the enzyme lipooxygenase, preferably 5-lipooxygenase, catalyzes the conversion of arachidonic acid to 5-hydroperoxyeicosatetraenoic acid and then to leukotriene A4, which ultimately contributes to inflammation or pain in immune challenged tissue such as skin.
[0031] "PLA-2 Pathway" means the pathway by which the phospholipase A2 (PLA-2) enzyme hydrolyzes phospholipids to form fatty acid lysophospholipid products such as arachidonic acid, which ultimately converts to leukotrienes and prostaglandins, which contribute to the inflammatory response in immune challenged tissue such as skin.
[0032] "VEGF Pathway" means the pathway by which VEGF (vascular endothelial growth factor) causes angiogensis (the formation of blood vessels) in immune challenged skin. In addition to inducing angiogenesis, VEGF also is responsible for increasing vascular leakage which will lead to increased edema in damaged tissue or skin.
[00331 "Immune challenged" means tissues or skin subjected to environmental, bacterial or viral assaults and where any one or more of the Pathways that contribute to inflammation have been triggered.
[0034] "Inflammation" means, when used to describe skin, that the skin has been subjected to moderate to severe environmental or chemical assault and is moderately to severely immune challenged. Examples of inflammation include sunburn, windburn, acne, insect bites, cuts, burns, rosacea, and the like. Inflammation typically produces one or more of redness, pain, and heat in the skin. An anti-inflammatory reduces the inflammation response.
[0035] "Inhibitor" or "inhibit" means, when used with a particular Pathway, an ingredient or combination of ingredients that inhibits the Pathway in whole or in part. For example, Histamine Pathway Inhibitor means an ingredient or combination of ingredients that inhibits the Histamine Pathway in whole or in part.
[0036] "Irritant", when used to describe skin, means that the skin has been aggravated by environmental assaults or toxins, or application of products containing one or more ingredients to which the skin is sensitized or otherwise incompatible.
Irritation may result in redness, itchiness, dryness, blemishes, enlarged pores, and so on. Irritated skin may also exhibit one or more of redness, pain, and heat.
[0037] "Pathway", when used with respect to inflammation, means a cascade of reactions that occurs when skin or tissue is exposed to immune challenge, and which ultimately contributes to skin inflammation.
[0038] Percentages mentioned herein shall mean percentage by weight unless otherwise indicated and are represented as wt/wt.
[0039] As used herein, "about" or "approximately" shall generally mean within 20 percent, preferably within 10 percent, and more preferably within 5 percent of a given value or range. Other than in the operating examples, or where otherwise indicated, all numbers expressing quantities of ingredients and/or reaction conditions are to be understood as being modified in all instances by the term "about".
[00401 "Film former" or "film forming agent" or "film forming resin" as used herein means a polymer which, after dissolution in at least one solvent (such as, for example, water and organic solvents), leaves a film on the substrate to which it is applied, for example, once the at least one solvent evaporates, absorbs and/or dissipates on the substrate.
[0041] "Keratinous substrates", as used herein, include but are not limited to, skin, hair, lashes and nails.
[0042] As used herein, the term ratio is used to express the relationship in quantity or amount of probiotic and antioxidant.
[0043] As used herein, the expression "at least one" means one or more and thus includes individual components as well as mixtures/combinations.
100441 The term "probiotic" means bacteria belonging to the order Lactobacillales, including but not limited to those from the genus Lactobacillus, Leuconostoc, Pediococcus, Lactococcus, Enterococcus, Oenococcus, Sporolactobacillus, Teragenococcus, and so on;
or a yeast belonging to the order Saccharomyces.

100461 The term "cosmetic" includes a composition in the form of aqueous gels or dispersions, emulsions, or anhydrous compositions and will generally be suitable for applying color to skin, hair, or lashes. Suitable aqueous gels contain from about 0.1 to 99%
water from about 1-99.9% of other cosmetic ingredients. Emulsions may be in the oil in water or water in oil form, or silicon and water, or water and silicon and generally comprise from about 0.1 to 99% water and from about 0.1 to 99% oil. Anhydrous compositions generally contain less than about 1% water, in addition to 0.1 to 90% oils, and optionally other ingredients.
[0047] The compositions of the invention may contain particulate materials in the form of pigments, inert particulates, or mixtures thereof. If present, suggested ranges are from about 0.01-75%, preferably about 0.5-70%, more preferably about 0.1-65% by weight of the total composition. In the case where the composition may comprise mixtures of pigments and powders, suitable ranges include about 0.01-75% pigment and 0.1-75%
