A method of measuring a wet friction of a bundle of hair, using a system which includes a friction probe having a contact surface and fitted with a weight in the range of from 10 g to 500 g, inclusive, a means for securing the bundle of hair, and a water bath, the friction probe being connected to a texture analyser, the method including the step of i) providing a bundle of hair fibres. The method also includes the steps of ii) aligning the bundle of hair fibres; iii) securing the bundle of hair fibres; iv) immersing the bundle of hair fibres under water in the water bath; v) contacting the bundle of hair fibres with the contact surface of the friction probe, which is fitted with the weight vi) moving the probe along the hair fibres; and vii) recording the friction generated under step vi).

The present disclosure relates to methods for treating, preventing and improving the condition and aesthetic appearance of skin, particularly, treating, preventing, ameliorating, reducing and/or eliminating fine lines and/or wrinkles of skin, by application of one or a combination of natural compounds or extracts that stimulate MAGP-1 expression and which improves the appearance of aged and/or photodamaged skin. The compositions of the invention are topically applied to the skin, or are delivered by directed means to a site in need thereof in an amount effective to improve the condition and aesthetic appearance of skin.

This document relates to methods and materials involved in providing a tooth, tooth component, or inorganic dental material (e.g., a human tooth, a human tooth component, or an inorganic dental material within a human's mouth) with a white appearance. For example, a whitening adhesive containing a conjugate of at least a polyamine, a polyphosphate, and one or more whitening agents (e.g., titanium dioxide, zinc oxide, and/or hydroxyapetite) can be used to provide a tooth, tooth component, or inorganic dental material with a whiter appearance.

An applicator device includes a formulation assembly with a dispenser portion and one or more formulation reservoirs, the formulation assembly being operable to dispense a formulation from the one or more formulation reservoirs onto one or more regions of a biological surface. The applicator device also includes a photo-dose assembly operably coupled to the formulation assembly, the photo-dose assembly having at least one illuminator oriented to focus electromagnetic energy onto one or more focal regions of a biological surface.

A water-in-oil personal care emulsion with water droplets size below 20 microns, the droplets containing solubilized cystine. A process of making an emulsion is also described.

The invention provides compositions and methods for promoting hair growth and reducing hair loss using bioactive extracts of curcumin, Withania somnifera, and saw palmetto. Tocotrienols, tocopherols, piperine extract, low molecular weight collagen, and hyaluronic acid are optionally included in the compositions and methods.

An oral care composition comprising zinc phosphate, stannous fluoride and an organic acid buffer system, as well as methods of using the same.

A cosmetic sheet to be attached to a skin includes a thin film, one surface of which is to be attached to a skin, a complementary color layer used for obscuring a discolored portion of the skin, the complementary color layer being disposed on the thin film and containing a colorant complementary to a color of the discolored portion, a light-scattering layer disposed on the complementary color layer and containing a reflective material; a coloring layer disposed on the light-scattering layer and containing a colorant; and a glossy layer disposed on the coloring layer and containing a gloss agent.

A water-in-oil personal care emulsion with water droplets size below 20 microns, the droplets containing solubilized cystine. A process of making an emulsion is also described.

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.
