Methods for transdermal delivery of glycosaminoglycans (GAGs) are disclosed, comprising applying ultrasound to the skin followed by topical administration of one or more GAGs optionally complexed with a polysaccharide carrier. When GAG is hyaluronic acid complexed with a modified starch, a transdermal delivery method is provided for facilitating delivery of high molecular weight hyaluronic acid into deep layers of the epidermis and to the dermis in a non-invasive, convenient and painless way. This transdermal delivery method may be applied in treatment of skin aging phenomena associated with collagen and/or hyaluronic acid depletion or loss.

The invention relates to a novel stabilized and solubilized topical formulation for cosmetic improvements and methods of making the same comprising multiplexed molecular penetration enhancers and essential and semi-essential amino acid protein binders for the topical application and transdermal delivery of one or more active ingredients and/or pharmaceutical agents. The invention further relates to the use of the topical formulation in connection with the providing of cosmetic improvements in individuals.

The present invention relates to an antibacterial, deodorization, easing of acne and atopic dermatitis, or skin calming-functional composition for Y-zone cleanliness containing Quercus acutissima sap, wherein the composition for Y-zone cleanliness is a composition used for cleaning a Y zone of women, which contains Quercus acutissima sap to provide antibacterial and deodorizing effects and to alleviate acne and atopic dermatitis or to provide a skin-calming function.

Disclosed is a Japanese camellia extract, obtained by extracting Camellia japonica flowers by way of a fatty substance or fatty substance mixture, and to a cosmetic composition including one such extract that has, in particular, a skin-moisturizing effect.

A method for producing exosomes comprises steps of: providing ultrasound stimulation directly or indirectly to cells; culturing a mixture of the cells and a medium for a predetermined time; and isolating exosomes from the mixture, wherein providing the stimulation directly to the cells comprises applying ultrasound stimulation to the medium containing the cells, and the providing the stimulation indirectly to the cells comprises applying ultrasound stimulation to the medium not containing the cells and then mixing the medium and the cells. This method for producing exosomes makes it possible to obtain exosomes having a hair regeneration effect not only from stem cells and progenitor cells that are difficult to isolate and multiply, but also from somatic cells that may be easily obtained and maintained, in high yield within a short time by ultrasound treatment that is a simple process.

The present disclosure relates to an ultraviolet absorber, a preparation method therefor, and an ultraviolet screening product containing same and, more specifically, to: an ultraviolet absorber, which comprises polymeric carbon nitrides having a heterocyclic structure comprising C and N; a preparation method therefor; and an ultraviolet screening product containing same.

Methods for forming dermatological compositions that deliver water and/or other hydrophilic compounds into or through the dermis using reverse micelles. The methods include forming compositions with an oil-based continuous phase and an emulsifier that form nanoparticle micelles. The nanoparticle micelles are formulated into biocompatible topical ointments that are stable at room temperature and can be distributed in consumer packaging and consumer distribution channels.

A pulp and skin extract from dried, seed-free Myrciaria dubia fruit. The Myrciaria dubia fruit has a maturity of at least 70%, a soluble solids/acidity ratio between 2.5 and 3, and it is rich in organic acids. The extract is obtained by solid-liquid extraction in a hydro-polyalcohol solvent selected from a hydro-glycerol and/or hydro-gylcolic solvent under agitation or with ultrasound. The extract is an active agent in cosmetic compositions, which reduce the signs of skin fatigue.

The present technology provides regenerative treatment methods and apparatus to stimulate hair growth. Regenerative treatments to stimulate hair growth include the subcutaneous application of carbon dioxide, and may also include suction, energy input, and topical application of nutrients to a patient's scalp. Regenerative treatment methods include an initial treatment phase and a maintenance treatment phase.

The present specification relates to a method for extracting a plant by using a skin serum that can be used for skin care. This method can further increase the process efficiency and extract active ingredients more effectively than conventional extraction methods using a solvent. Thus, the method can increase customer satisfaction and promote the development of relevant industries.
