Exfoliating Cosmetic Composition to Reduce Skin Irritation

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing skincare products that aim to improve skin appearance through exfoliation often cause irritation and have prolonged recovery periods, failing to effectively reduce unwanted side effects while achieving desired exfoliation benefits.

Innovation Solution

A topical skin composition combining 4-tert-butylcyclohexanol, plankton extract, Phragmites communis extract, Poria cocos extract, Cucurbita pepo (pumpkin) seed extract, and other ingredients, which work together to exfoliate the skin, reduce irritation, and enhance skin radiance and smoothness without the negative effects typically associated with exfoliating products.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional exfoliating cosmetic compositions are used, then skin renewal and visual appearance improvement are achieved, but skin irritation and prolonged recovery periods occur

Engineering Contradiction:

Improveskin renewal effectivenessVSAvoidskin irritation

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments the exfoliation process into multiple gentler steps using different enzyme types (plant-derived and animal-derived enzymes) rather than using a single aggressive chemical exfoliant. This allows progressive skin renewal without overwhelming the skin barrier

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces soothing agents and moisturizing components as intermediaries between the exfoliating enzymes and the skin. These intermediaries buffer the potential irritation while allowing the enzymatic exfoliation to proceed effectively

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If strong exfoliating agents are used to improve skin radiance and smoothness, then exfoliation effectiveness increases, but negative side effects and irritation increase

Engineering Contradiction:

Improveexfoliation efficiencyVSAvoidside effects from exfoliation

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent changes the parameters of exfoliation by using enzymatic action at controlled temperatures and pH levels, replacing harsh chemical exfoliants. This maintains high exfoliation efficiency while operating within safer parameter ranges that minimize skin damage

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite formulation combining multiple enzyme types, soothing agents, and moisturizing components. This composite approach delivers effective exfoliation while the integrated soothing and moisturizing elements counteract potential side effects

Inventive Principle:

Principle #40Composite materials
