The disclosure relates to the identification and the use of compounds which regulate the expression of at least one Sestrin gene, for preventing and/or attenuating skin ageing, and/or for hydrating the skin and/or for regulating skin pigmentation. The method includes the following steps: a. bringing at least one test compound in contact with a sample of human keratinocytes or melanocytes; b. measuring the expression of at least one Sestrin gene chosen from SESN3, SESN2 and SESN1 in the keratinocytes or melanocytes; c. selecting the compounds for which an activation of at least 1.6 fold of the expression of at least one of the genes is measured in the keratinocytes treated in a. compared with the untreated keratinocytes, or for which a significant modulation of the expression of at least one of the genes is measured in the melanocytes treated in a. compared with the untreated melanocytes.

Use of Mesembryanthemum crystallinum L. callus extract in the manufacture of a medicament or a skin care product, wherein the medicament or skin care product is for at least one of delaying skin cell aging, nursing skin, repairing skin, treating skin cancer, and preventing skin cancer.

The present invention relates to pharmaceutical compositions comprising collagen and hyaluronic acid, and optionally containing silver. Said compositions may be in the form of a hydrogel, pad or dry spray. The invention also relates to the preparation process of said compositions in pad form. Finally, the invention relates to the use of the compositions for the treatment of skin lesions.

Problem The present invention is to provide a generation method that can generate 3,5-dihydroxy-4-methoxybenzyl alcohol, which was not found at all from raw oyster meat originally, at an extraction phase of oyster meat essence. Solution The present invention heats raw oyster meat from which 3,5-dihydroxy-4-methoxybenzyl alcohol is not detected in a raw state at 98° C. to 100° C. for six hours or more to generate 3,5-dihydroxy-4-methoxybenyl alcohol from oyster meat liquid on which the heating process has been performed.

The invention relates to the 4-((2E,4E,6E)-octa-2,6,4-trienamid)butanoic acid; its use in the therapeutic and cosmetic field for topical application to the skin to achieve a combined antioxidant activity against ROS together with an anti-inflammatory effect and an effect of promoting the production of hyaluronic acid, so as to oppose at the same time the oxidizing action of free radicals and inflammatory effects, in order to preserve the physiological conditions of human epidermis and skin homeostasis and prevent skin aging (anti-aging); the compositions for therapeutic and cosmetic use which comprise 4-((2E,4E,6E)-octa-2,6,4-trienamid)butanoic acid as active ingredient, formulated with excipients for topical use suitable for local administration on the skin.

The present invention relates to a composition containing a material for regulating the expression of ABH antigens and, more specifically, to a composition capable of: controlling sebum production and alleviating skin trouble by regulating the expression of ABH antigens; preventing skin pore enlargement by providing antioxidant effects; and defending against skin irritation production.

The present invention relates to a method of cultivating stem/progenitor cells of the amniotic membrane of umbilical cord that comprises obtaining a tissue explant from the amniotic membrane of umbilical cord and cultivating the tissue explant in suitable cultivation media and cultivation conditions over a suitable period of time. The method may include isolating the stem/progenitor cells from the tissue cultures. The stem cells may be epithelial or mesenchymal stem/progenitor cells. The isolated stem cell cells can have embryonic stem cell-like properties and can be used for various therapeutic purposes.

A yellow reduced pyrroloquinoline quinone crystal having a solubility in water of 0.040 to 0.20 (mg/mL).

Disclosed is a composition of a synergistically effective ratio of an hydroxamic acid, salt and/or a complex thereof and an antioxidant. The composition is effective to reduce or prevent lipid peroxidation upon exposure of a lipid to UV light. Personal care and other formulations are included within the scope of the invention, as are the related methods of increasing the antioxidant potential of an antioxidant, of reducing a rate of peroxidation of constituent lipids in a personal care formulation over a time period and of reducing peroxidation of lipids within mammalian skin cells.

The invention relates to the manufacturing and use of pharmaceutical compositions of medicines (ophthalmic preparations) comprising a mitochondria-addressed antioxidant and a set of auxiliary substances providing effective treatment for ophtalmological diseases in humans and animals.
