Abstract

Disclosed is a composition of freeze-dried formulation which is mixed with a medium composition to be applied to the skin. Based on the total weight of the composition of freeze-dried formulation andthe medium composition, freeze-dried hyaluronic acid is present in an amount of 0.5 dry wt% or more. The freeze-dried hyaluronic acid includes crosslinked hyaluronic acid and low-molecular weight hyaluronic acid at a weight ratio of 1:5 to 3:1. Thus, the composition allows incorporation of a high concentration of hyaluronic acid capable of retaining a moisturizing protective film, while supplementing skin constitutional ingredients, provides a high moisturizing effect without slipperiness and stickiness, has a dried form and requires no preservative, or the like, and can stabilize an unstableactive ingredient.

Description

technical field

[0001] The present invention relates to a freeze-dried formulation composition and a skin external preparation cosmetic kit (kit) containing the same. Background technique

[0002] Freeze-dried cosmetics can also be used as preservative-free formulations because their formulations do not contain moisture, which is conducive to the loading of functional ingredients that are easily affected by moisture and solvents, and do not require preservative treatment. This freeze-dried cosmetic dosage form needs to be dissolved in a solvent such as water or essence before use, and depending on the dosage form, it may be inconvenient to use due to extremely slow dissolution speed or extremely low viscosity.

[0003] In addition, hyaluronic acid is a biological component found in body fluids, eyeballs of cattle, cockscombs, bradycardia of animals, placenta, etc., and is present in high concentrations in connective tissues and skin in particular. In addition, hyaluronic ac...
