The presently disclosed subject matter relates to a system for customizing a cosmetic product. The system includes: an interface device, in electronic communication with a single batch formulation device. The single batch formulation device is configured to formulate a customized cosmetic product, and a threaded container configured to be imported into the single batch formulation device containing a base and exported from the single batch formulation device containing the customized cosmetic.

A treatment application garment, such as a glove or a sock, is disclosed. The garment allows for various treatments directed toward the fingers and toes, such as the fingernails and toenails. For example, each digit of the garment may contain an absorbent pad containing acetone. The hand or foot is inserted into the garment such that the nail is positioned below the absorbent pad containing the acetone, allowing the acetone to be constantly applied to the nail to remove polish therefrom. After the treatment is complete, the glove may be removed and the open end thereof tied off, thereby containing the acetone and the smell thereof within the glove. Other features and treatments are also disclosed.

A cosmetic composition including a solvent A, a solvent B, a polymer C and a colorant. The solvent A is at least one selected from the group consisting of ethanol, n-propanol and isopropanol. A boiling point of the solvent B is 150° C. or higher. The solvent B is compatible with the solvent A, and the polymer C is soluble in the solvent A and insoluble in the solvent B. A content of the solvent B is 5% by mass or more and 40% by mass or less, and a ratio by mass of a content of the solvent A to a content of the solvent B [solvent A/solvent B] in the cosmetic composition is 1 or more and 15 or less.

The present disclosure relates to a curable nail strengthening composition comprising a polymerizable material, at least one penetrating agent, and at least one curing agent. The strengthening composition penetrates the nail and is cured within the nail plate without cross-linking the nail proteins. Methods for strengthening and repairing nails are also disclosed.

The invention relates to a method of customizing a nail-biting and/or finger sucking treatment solution, and a kit for providing a nail-biting and finger sucking treatment that is customizable for a wide range of afflicted users seeking to break a persistent nail-biting and/or finger sucking habit. In exemplary embodiments, the composition kit includes two separate containers, a first container having a nail growth-promoting, waterproofing composition that may be applied directly on a user's nails; and a second container may include an additive for customizing a bitterness factor of the first composition. Typically, the first container includes an applicator such as a brush. To facilitate adding the additive in a manner that is easily customizable, the second container may include a dropper for adding small doses of the additive composition to the first composition. The customizable kit allows the user to safely adjust the bitterness so that the treatment remains effective.
