Young Hibiscus Sinensis Flower Extract for Skin Aging

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing skincare products using Hibiscus sinensis flower extracts do not effectively address skin aging due to the misconception that red flowers have higher antioxidant activity, when in fact, young white to light pink flowers contain molecules like N-(1-deoxy-1-fructosyl)-proline and sarmentosin epoxide that provide superior antiaging benefits.

Innovation Solution

Utilizing extracts from young Hibiscus sinensis flowers with white to light pink color, rich in N-(1-deoxy-1-fructosyl)-proline and sarmentosin epoxide, for a cosmetic active ingredient that promotes skin regeneration, regulates epigenetic factors, boosts cell detoxification, limits inflammation, and strengthens the skin immune barrier.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Quantity of substance

If red Hibiscus sinensis flowers are used for extract, then antioxidant activity is improved according to prior art, but antiaging efficacy on skin is worsened due to absence of key molecules

Engineering Contradiction:

Improveanthocyan contentVSAvoidantiaging efficacy

Core Design Contradiction:

Quantity of substanceVSReliability

Solution Approach 1:

The invention changes the selection parameter from flower color (red) associated with high anthocyan content to flower developmental stage (young white to light pink) associated with presence of N-(1-deoxy-1-fructosyl)-proline and sarmentosin epoxide. This parameter change resolves the contradiction by prioritizing antiaging efficacy over antioxidant activity measurement.

2Reliability

If young white to light pink Hibiscus sinensis flowers are used for extract, then antiaging efficacy is improved due to presence of N-(1-deoxy-1-fructosyl)-proline and sarmentosin epoxide, but antioxidant activity measurement is worsened compared to red flowers

Engineering Contradiction:

Improveantiaging efficacyVSAvoidanthocyan content

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The invention shifts the evaluation parameter from antioxidant activity (anthocyan content) to antiaging efficacy markers (N-(1-deoxy-1-fructosyl)-proline and sarmentosin epoxide). This resolves the contradiction by demonstrating that young flowers excel in the target function (antiaging) even if they score lower on traditional antioxidant metrics.

Inventive Principle:

Principle #35Parameter changes

3Ease of manufacture

If flower color is used as selection criterion, then manufacturing process is simplified, but antiaging efficacy is reduced by selecting red flowers instead of young white to light pink flowers

Engineering Contradiction:

Improveflower selection processVSAvoidantiaging efficacy

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The invention changes the selection criterion from flower color (easy to observe) to flower developmental stage indicated by color transition from white to light pink. This maintains ease of manufacture while improving antiaging efficacy by targeting young flowers at the optimal stage before they mature to red.
