Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Skin sagging is a result of qualitative and/or quantitative deficit of elastin and elastic fibers, leading to loss of skin elasticity and resilience, particularly noticeable in facial features and body contours.

Innovation Solution

A cosmetic treatment using a plant extract from the Engelhardtia genus, specifically Engelhardtia chrysolepis Hance, is applied to stimulate elastin production, improve elastic fiber network quality, and strengthen the dermo-epidermal junction, utilizing an alcoholic extract mixed with a physiologically acceptable medium.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional cosmetic treatments are used, then skin elasticity is maintained to some extent, but they cannot effectively address the qualitative and quantitative deficit of elastin and elastic fibers

Engineering Contradiction:

Improveskin elasticityVSAvoidelastin synthesis capability

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent changes the chemical composition parameter by introducing a specific plant extract from the Engelhardtia genus, which contains unique bioactive compounds not present in conventional cosmetics. This parameter change enables the extract to stimulate elastin synthesis and improve elastic fiber network quality, directly addressing the deficit that conventional treatments cannot resolve

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If the skin is stretched repeatedly, then the skin adapts to some degree, but it loses resilience and returns to shape less easily

Engineering Contradiction:

Improveskin stretch adaptationVSAvoidskin resilience

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent applies preliminary action by using the Engelhardtia extract to pre-strengthen the elastic fiber network and stimulate elastin production before significant damage occurs. This preventive approach enhances the skin's ability to return to its original shape after stretching, maintaining resilience even with repeated mechanical stress

Inventive Principle:

Principle #10Preliminary action

3Strength

If the dermo-epidermal junction weakens due to aging, then skin structure deteriorates, but conventional treatments cannot effectively strengthen it

Engineering Contradiction:

Improvedermo-epidermal junction strengthVSAvoidtreatment effectiveness

Core Design Contradiction:

StrengthVSEase of manufacture

Solution Approach 1:

The Engelhardtia extract acts as an intermediary substance that mediates between the external environment and the dermo-epidermal junction. It penetrates the skin barrier and stimulates the production of structural proteins (collagen IV, VII, and laminin V) that strengthen the junction, making the treatment effective where conventional products fail

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

The composition comprises a plant extract of the Engelhardtia genus, preferably the species is Engelhardtia chrysolepsis Hance. The treatment according to the invention is a repairing treatment to improve the number of elastic fibres and the quality of its network. Skin elasticity is improved and this helps decrease jowls and eyelids drooping, and the corresponding skin folds. The treatment is particularly adapted to a pre-menopausal or menopausal woman skin.
