Microneedle Cosmetic Composition with Cica Extract
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetics often cause skin irritation and have stability issues due to their natural-derived raw materials, leading to ineffective skin care and potential side effects, particularly in maintaining skin moisture and barrier function.
Innovation Solution
A cosmetic composition featuring microneedles impregnated with cica extract, manufactured through hydrolysis, sieving, drying, and reduced-pressure agitation, to enhance skin absorption and regeneration, improving skin turnover, absorption, and texture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cosmetics use natural-derived raw materials, then they are marketed as safe and effective, but they cause skin irritation and have stability issues
Solution Approach 1:
The patent changes the physical state and delivery parameters of the active ingredient by using microneedles to transport cica extract directly into the skin, bypassing the problematic conventional cosmetic formulation that causes irritation while maintaining stability
Solution Approach 2:
The microneedle acts as an intermediary device that delivers the cica extract directly to the skin, eliminating the need for conventional cosmetic bases (glycerin, sorbitol, electrolytes) that cause irritation and stability issues
2Stability of the object's composition
If conventional cosmetics use electrolytes like sodium pyrrolidone carboxylate and sodium lactate, then they provide moisturizing effects, but they have strong electrolytic properties making it difficult to maintain stability in formulation
Solution Approach 1:
The patent extracts and isolates the beneficial cica extract as the sole active ingredient delivered via microneedles, removing the problematic electrolyte mixture that causes formulation instability while maintaining moisturizing and skin-health benefits
3Reliability
If conventional cosmetics are used to maintain skin moisture and barrier function, then they can prevent skin problems, but they feel unpleasant due to excessive stickiness
Solution Approach 1:
The patent replaces the conventional cosmetic application system (creams, lotions requiring spreading and absorption) with a microneedle delivery system that directly transports active ingredients into the skin, eliminating the sticky sensation while maintaining skin barrier benefits
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The cosmetic composition effectively shortens skin turnover cycles, enhances skin regeneration, increases absorption rates, and improves skin texture, while being safe and non-irritating, as demonstrated by statistical significance in clinical trials.
Implementation Method 1
agitating the dried microneedle and cica extract under a reduced pressure to impregnate the cica extract into inner tubes of the microneedles
Implementation Method 2
collecting sponge and then hydrolyzing them

AI summary
Disclosed is a cosmetic composition including microneedles impregnated with a cica extract as an active ingredient, and a method for manufacturing the same. The composition provides elasticity and regenerative power to the skin, and has an excellent effect of improving skin turnover, skin absorption amount, absorption depth, absorption rate, and smoothing skin texture, that is, skin roughness whereby the cosmetic composition may be usefully used.
