A cosmetic gel sheet suitable for a cosmetic field or a medical field is provided. The cosmetic gel sheet of the present invention contains carboxy group-containing water-soluble polymer, polyalcohol, and acid as essential constituent components. Carboxy group-containing polysaccharide can be suitably used as the carboxy group-containing water-soluble polymer. Water content in the gel sheet is 30% by weight, but it is more preferable if the water content is 10% by weight or less. In the cosmetic gel sheet of the present invention, the gel sheet can be manufactured by drying an aqueous solution containing carboxy group-containing water-soluble polymer, polyalcohol, and acid as essential components. Wherein, it is desirable that content of the acid in the aqueous solution is adjusted to a value appropriate for setting pH of the aqueous solution to 2.0-4.0.

The invention relates to a bracelet or strap, in particular a watch band, comprising at least one organic material based portion intended to be placed in contact with the user's skin, said organic material containing at least one functional agent, such as an antibacterial agent. According to the invention, said organic material also contains a cosmetic agent for the skin, arranged to be able to be in contact with the user's skin when the bracelet is worn.

The invention also concerns methods for manufacturing such a bracelet or strap.

A preparation method of a hydrogel of a mercapto-modified macromolecular compound includes the steps of combining the mercapto-modified macromolecular compound with an acrylated macromolecular compound and/or an acrylated micromolecular crosslinker. The mercapto-modified macromolecular compound can be crosslinked with the acrylated macromolecular compound and/or the acrylated micromolecular crosslinker under physiological conditions to form the hydrogel. Due to the rapid mercapto-vinyl crosslinking reaction, the formed hydrogel system can be quickly gelled in situ after being injected into the body. The hydrogel is thus suitable for use in the fields of biomedicine, medical cosmetic plastic surgery and cosmetics.

The disclosure describes an oil-in-water composition for skin external application using a gel of crosslinked hyaluronic acid or a salt thereof and having a sherbet-like texture and feeling of use. The composition of the disclosure comprises the gel particles of crosslinked hyaluronic acid or a salt thereof and emulsion particle having a specific particle size distribution of D(0.5) in an aqueous phase and an oil phase, respectively, so that the composition has a particulate feeling such as sherbet, mashed potato or meringue while having a fluffy appearance or texture, and also provides a refreshing feeling of use when applied, and is easy to clean by comprising the aqueous phase as an outer phase.

The present invention provides improved anti-aging skin cream formulations. The anti-aging cream formulations contain tretinoin, niacinamide, hyaluronic acid, collagen, red wine extract, α-tocopheryl acetate, Butyrospermum parkii (shea butter) extract, and suspendisse cream. The present invention also provides kits containing the formulations, methods of making the formulations as well as methods of using these formulations to visibly reduce signs of aging.

The present invention relates generally to cosmetic compositions and methods that can be used to increase skin hydration, increase adenosine triphosphate (ATP) production in skin, increase antioxidant capacity of skin, reduce glycation of skin, or a combination thereof. In particular, topical application of the compositions to skin increases adenosine triphosphate (ATP) production in skin by at least 10%, increases antioxidant capacity of skin, and/or reduces glycation of skin by at least 50%. In particular, the compositions can include Chamomilla recutita (Matricaria) flower extract, Vitis vinifera (Grape) seed extract, hydrolyzed sodium hyaluronate, Natural Moisturizing Factors (NMF), and optionally carnosine.

A topical skin moisturizing composition comprising: (a) one or more phospholipids; (b) a plurality of demulcents; (c) one or more polymeric moisturizing agents; (d) one or more preservatives; (e) one or more vitamins; and (f) an aqueous vehicle. The moisturizing composition can have an osmolality in the range of 80 mOsm/kg to 500 mOsm/kg. The composition is configured for use on the face and, particularly for application on and around the delicate eye area including the eyelids.

A composition is disclosed that includes pure silk fibroin-based protein fragments that are substantially devoid of sericin, wherein the composition has an average weight average molecular weight ranging from about 17 kDa to about 38 kDa, wherein the composition has a polydispersity of between about 1.5 and about 3.0, wherein the composition is substantially homogeneous, wherein the composition between 0 ppm to about 500 ppm of inorganic residuals, and wherein the composition includes between 0 ppm to about 500 ppm of organic residuals.

The invention relates to a hydrogel product comprising glycosaminoglycan molecules as the swellable polymer, wherein the glycosaminoglycan molecules are covalently crosslinked via crosslinks comprising a spacer group selected from the group consisting of di-, tri-, tetra-, and oligosaccharides.

This invention relates to a cosmetic combination product comprising a first cosmetic composition comprising glucosamine or one of the salts thereof, a second cosmetic composition comprising hyaluronic acid, and possibly a third cosmetic composition comprising collagen, a cosmetic composition comprising glucosamine or one of the salts thereof, hyaluronic acid, and possibly collagen, the uses thereof, in particular for inducing the synthesis of hyaluronic acid and as such combat aging of the skin affecting the keratinocytes and/or the fibroblasts and the dermis, as well as a cosmetic method that implements these combination products and compositions.
