Provided are a composition including a compound of the following chemical formula as an active ingredient, and a method of enhancing a skin barrier by applying it to the skin:

##STR00001##

The present disclosure relates to a composition for alleviating ultraviolet ray-induced skin damage or moisturizing skin, more particularly, to a composition containing an Actinidia polygama extract as an active ingredient. The composition can alleviate the reduction of skin moisture caused by ultraviolet ray-induced skin barrier damage and the resultant skin dryness, reduced skin elasticity and increased skin roughness and, as such, can be utilized as a food composition for alleviating ultraviolet ray-induced skin damage or moisturizing skin and, furthermore, as a health functional food or pharmaceutical composition, an animal feed composition, a pharmaceutical composition for animals or a cosmetic composition.

A water-soluble and/or water-swellable hybrid polymer comprising: (i) from 5 wt.-% to 95 wt.-% water-soluble and/or water-swellable polysaccharide polymer; (ii) from 5 wt.-% to 95 wt.-% synthetic polymer comprising: (a) from 90 mol-% to 99.9 mol-%, preferably 95 mol-% to 99.5 mol-% of repeating units according to Formula (1) ##STR00001## (b) from 0.01 mol-% to 10 mol-%, preferably to 5 mol-%, more preferably to 3 mol-% of crosslinking or branching units, wherein the crosslinking or branching units result from the incorporation of a monomer comprising at least two olefinically unsaturated double bonds;
wherein components (i) and (ii) are polymerized by radical precipitation polymerization in a polar solvent.

A cosmetic method for modulating pigmentation in a subject includes administering a modulator of angiotensin-converting enzyme 2 (ACE2 modulator) to the subject. The ACE2 modulator can be an inhibitor of angiotensin-converting enzyme 2 (ACE2 inhibitor), in which case, the ACE2 inhibitor can be administered to increase pigmentation in the subject. The ACE2 modulator can also be an activator of angiotensin-converting enzyme 2 (ACE2 activator), in which case the ACE2 activator can be administered to decrease pigmentation in the subject. The treatment of inflammatory skin disease can also be achieved by inhibition of angiotensin-converting enzyme 2.

The disclosure relates generally to insect repellent compositions and methods for using the same.

The present invention provides a treatment of aging or UV-damaged skin comprising topically administrating a formulation comprising (i) cannabidiol and (ii) omega-3 fatty acid selected from eicosapentaenoic acid and docosahexaenoic acid and combinations thereof.

The invention further relates to a topical formulation comprising: cannabidiol; and, omega-3 fatty acid selected from eicosapentaenoic acid and docosahexaenoic acid and combinations thereof.

The present invention relates to an association comprising or consisting of a mixture of cannabidiol or cannahigerol and palinitoyl tripeptide-8, and to the use thereof for treating or soothing sensitive and/or reactive skins or as an after-sun ointment for soothing solar erythema.

The present invention primarily relates to the use of a fatty acid ester, or a mixture comprising, or consisting of, two or more fatty acid esters, in a cosmetic product for inhibiting growth of microorganisms on a mammal's skin or mucosa, and/or preserving the cosmetic product against microbial growth, wherein the fatty acid ester, or at least one of the two or more fatty acid esters in the mixture, is selected from the group consisting of 3-hydroxypropyl caprylate, 3-hydroxypropyl undecylenate and glyceryl monoundecylenate.

Cosmetic compositions comprising at least one cyclodextrin which is at least partially present in the form of solid particles dispersed in a physiologically acceptable medium, that the cyclodextrin particles have a volume average size d(4,3), of less than or equal to 20 μm, more preferentially less than or equal to 12 μm, and most preferentially less than or equal to 8 μm, and a size distribution by volume, of which the characteristic diameters d(10), d(50) and d(90) are such that: a. the diameter d(10) is less than or equal to 5.0 μm, preferentially less than or equal to 2.5 μm, b. and the diameter d(50) is less than or equal to 15.0 μm, preferentially less than or equal to 10.0 μm, c. and the diameter d(90) is less than or equal to 30.0 μm, preferentially less than or equal to 25.0 μm.

A method of preventing progression of an appearance or effect of aging in a subject is provided. A method of preventing, limiting, or inhibiting injury to skin integrity in a subject is also provided. A method of substantially maintaining a state of skin integrity in a subject is further provided. A method of preventing a topographical change of a cutaneous layer of skin in a subject is still further provided. The methods comprise administering an effective amount of a preparation comprising ammonia oxidizing microorganisms to the subject. Related preparations and kits are also provided.
