Fatty acid amides, but not free fatty acids or fatty acid esters, in combination with either retinol or retinyl ester resulted in a synergistic enhancement in keratinocyte proliferation and synergistic inhibition of keratinocyte differentiation. The effects of the retinol or retinyl esters in combination with fatty acid amides were analogous to treatment with retinoic acid.

Skin care compositions containing fatty acid amides and retinol or

A composition for topical application to the skin for alleviation or prevention of dry flaky skin conditions, dandruff or ache comprising one or more stratum corneum trypsin-like enzymes. The composition may further comprise an additional enzyme selected from glycosidases, other proteases, lipases and mixtures thereof. Optional additional active ingredients include sunscreens, lipids, hydroxy carboxylic acids and ketocarboxylic acids.

Skin care method and composition

An efficient method of producing phytosphingosine-containing ceramide one comprising: (a) obtaining a phytosphingosine base from tetraacetylphytosphingosine (TAPS) by a deacetylation reaction wherein the TAPS is produced by fermentation of cells of the F-60-10 mating type strain of Hansenula ciferrii using a fed-batch mode and a non-fermentable carbon source; and (b) coupling together the phytosphingosine base and a fatty acid/.omega.-hydroxy fatty acid component wherein the .omega.-hydroxy fatty acid component is prepared by a process which includes Kolbe synthesis.

Method of synthesizing lipids and cosmetic composition comprising them

Compositions for treating skin which contain azole in combination with a lipid ingredient. The compositions attain keratinocyte differentiation and provide additional benefits. Also disclosed is a method of improving or preventing the appearance of wrinkled, flaky, aged, photodamaged skin by applying to skin a composition containing in a cosmetically acceptable vehicle an azole and a lipid ingredient.

Compositions for topical application to skin

A composition for topical application to skin which comprises: (i) from 0.0001 to 10% by weight of one or more ceramide pathway intermediates or precursors thereof and mixtures thereof; and (ii) a balancing amount of a cosmetically acceptable vehicle for the intermediate.

Cosmetic composition

Cosmetic compositions containing tricholine citrate (TCC). TCC stimulates keratinocyte growth, does not inhibit keratinocyte differentiation and increases the phospholipid levels in keratinocytes. Thus, TCC provides improved conditioning, improved youthful appearance, moisturization and improvement in the appearance of photodamaged skin.

Cosmetic compositions containing tricholine citrate

A composition for topical application to the skin for alleviation or prevention of dry flaky skin condition, dandruff or acne comprising stratum corneum chymotrypsin-like enzyme. The composition may additionally comprise a second enzyme selected from glycosidases, other proteases, lipases and mixtures thereof.

Dimethyl imidazolidinone in combination with either retinol or retinyl ester resulted in a synergistic enhancement in keratinocyte proliferation and synergistic inhibition of keratinocyte differentiation. The effects of the retinol or retinyl esters in combination with dimethyl imidazolidinone were analogous to treatment with retinoic acid.

Skin care compositions containing dimethyl imidazolidinone and retinol

Compositions for treating skin, hair and nails which contain 25-hydroxycalciferol in combination with a lipid ingredient. The compositions avoid the toxic effects of 1,25-dihydroxycalciferol, yet attain keratinocyte differentiation and provide additional benefits. Also disclosed is a method of improving or preventing the appearance of wrinkled, flaky, aged, photodamaged skin by applying to skin a composition containing in a cosmetically acceptable vehicle 25-hydroxycalciferol and a lipid ingredient.

Compositions for topical application to skin, hair and nails

Skin treatment compositions for the enhancement of lipid production in the skin. Compositions contain a thiol, or an S-ester, in combination with L-serine or N-acetyl-L-serine.

Composition for enhancing lipid production in skin
