New extracts of microalgae, halophytes and psammophilous plants are suggested, obtainable by treating said microalgae and plants with a solvent selected from the group consisting of C.sub.1-C.sub.4 aliphatic alcohols, ethyl acetate, water or their mixtures, removing the dissolved extracts from the residues and recovering the pure extracts from the solvent. The extracts show excellent activity as regulators of the metabolism of human sebaceous glands.

The present invention provides a composition comprising a mud rich in various active ingredients such as natural minerals, wherein the composition has a sufficiently low viscosity so as to stably provide a sheet-type mud pack, and a mud pack comprising the same. The mud pack comprising the composition is excellent in sebum control ability and pore shrinking ability, and is very effective for improving skin smoothness.

Methods of improving (i.e., changing) the skin of a patient or consumer who does not have sensitive, dry, very oily, pigmented and/or wrinkle-prone skin to slightly oily, resistant non-pigmented and tight skin.

A composition for reducing sebum production in the skin of a user, the composition comprising: a liquid carrier; and Pyridoxine Cyclic Phosphate; wherein the Pyridoxine Cyclic Phosphate is present in the composition in a concentration sufficient to reduce sebum production in the skin of a user when the composition is applied to the skin of a user.

Embodiments herein are directed to moisturizing compositions comprising interpenetrating polymer networks, methods of making moisturizing compositions and methods of using moisturizing compositions.

The present invention relates to a composition comprising an aqueous phase, at least one mattifying filler and at least one silane corresponding to formula (I) below and/or oligomers thereof: R.sub.1Si(OR.sub.2).sub.z(R3).sub.x(OH).sub.y(I) in which: •Ri is a linear or branched, saturated or unsaturated C1-C22 hydrocarbon-based chain, which may be substituted with an amine group NH2 or NHR (R=C1-C20 and especially C1-C6 alkyl, C3-C40 cycloalkyl or C6-C30 aromatic); or with a hydroxyl group, a thiol group, an aryl group (more particularly benzyl), which is substituted or unsubstituted; Ri possibly being interrupted with a heteroatom (O, S or NH) or a carbonyl group (CO), •R2 and R3, which may be identical or different, represent a linear or branched alkyl group comprising from 1 to 6 carbon atoms, •y denotes an integer ranging from 0 to 3, and •z denotes an integer ranging from 0 to 3, and •x denotes an integer ranging from 0 to 2, •with z+x+y=3, The invention also relates to a cosmetic process for making up and/or caring for keratin materials comprising a step of applying a composition according to one of the preceding claims to the said materials.

The present invention relates in part to nucleic acids, including nucleic acids encoding proteins, therapeutics and cosmetics comprising nucleic acids, methods for delivering nucleic acids to cells, tissues, organs, and patients, methods for inducing cells to express proteins using nucleic acids, methods, kits and devices for transfecting, gene editing, and reprogramming cells, and cells, organisms, therapeutics, and cosmetics produced using these methods, kits, and devices. Methods and products for altering the DNA sequence of a cell are described, as are methods and products for inducing cells to express proteins using synthetic RNA molecules, including cells present in vivo. Therapeutics comprising nucleic acids encoding gene-editing proteins are also described.

The invention relates to a composition, notably a cosmetic and/or dermatological composition, in particular for caring for a keratin material, notably the skin and in particular facial skin, which is in the form of an oil-in-water, O/W, emulsion, and comprising at least a) particles of at least one hydrophobic silica aerogel, b) an ester hydrocarbon-based oil, and c) an ether hydrocarbon-based oil, in which said ether and ester oils are present in an ether oil/ester oil weight ratio ranging from 1 to 2.

A composition for sebum control and pore reduction, and its use for controlling sebum and reducing pore of skin are disclosed. The external-use skin preparation composition contains, as an active ingredient, extracts of one or more medicinal herbs selected from the group consisting of Cimicifugae rhizoma, Solani nigri herba, Glycyrrhiza uralensis, Clematis mandshurica, Acanthopanax senticosus, Inulae radix and Dioscorea japonica, and thus it not only can control the production of sebum and alleviate skin troubles, but also provide antioxidant effects, prevent pore enlargement, or prevent occurrence of skin irritation.

Disclosed is an efficacious, low-pH skin care composition that provides good sensory properties and has a low skin irritation potential. The low-pH composition includes an effective amount of a vitamin B.sub.3 compound and, optionally, one or more additional skin care actives to provide a skin health and/or appearance benefit. The low-pH composition also includes a salt/acid pH buffer system, an acid tolerant polymeric thickener and, optionally, a silicone fluid having a kinematic viscosity of 100 cSt or less at 25° C. The pH of the low-pH composition can range from 2.0 to 5.0.
