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 g/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,

[0022] "Adhesion Pathway" is the pathway by which cells adhere to blood vessels and other skin tissues when injury or immune challenge has occurred.

[0023] hemotaxis 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 cA P to the corresponding 5'-nucleotide monophosphate. PDE4 is abundant and is the major regulator of cAMP metabolism in almost every proinflammatory 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 ceils) which will ultimately lead to a decrease in the production and release of proinflammatory 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 variety of cells (including smooth muscle cells and endothelial cells in blood vessels) exerting its biologic effects, These effects include vasodilation, separation of endotheliai 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 phospho!ipase 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.

[0033] "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 ail instances by the term "about".

[0040] "Film former" or "film forming agent" or "fi!m 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,

EXAMPLE

[0053] Antioxidant/Probiotic composition

[0054] Inflamation was measured by the magnitude of cytokine release after exposure to a single dose of irritant. The anti-inflammatory potential of the skin model is measured by the tissue viability. The tissue viability is determined by measuring the relative conversion of MTT (3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) in the skin mode! treated with the antioxidant/probiotic composition, probiotic alone, antioxidant alone, and a negative/solvent control (sterile, deionized water) and a positive control (hydrocortisone cream).

[0055] The skin model is the EpiDerm™ skin model (MatTek Corporation, Ashland, MA). The skin model was exposed to antioxidant/probiotic composition, probiotic alone, antioxidant alone, and a negative/solvent control, applied topically to the skin model, for six hours in the presence and absence of phorbol-12-myristate 13-acetate (PMA). The toxicity of the test article was determined by the NAD(P)H-dependent microsomal enzyme reduction of MTT.
