Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current research lacks effective solutions for preventing or improving skin aging by controlling cellular senescence of melanocytes, which is a significant factor in skin aging.

Innovation Solution

A cosmetic composition containing 3,4,5-trimethoxycinnamate thymol ester or its stereoisomer, salt, hydrate, or solvate is used to reduce cellular senescence of melanocytes, thereby alleviating changes in melanocyte morphology and reducing β-galactosidase activation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional anti-aging ingredients are used, then general skin aging is addressed, but cellular senescence of melanocytes is not effectively controlled

Engineering Contradiction:

Improveeffectiveness in controlling melanocyte cellular senescenceVSAvoidresearch complexity on melanocyte senescence mechanisms

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent identifies and targets specific parameters related to melanocyte cellular senescence, such as β-galactosidase activation and RNA age, using 3,4,5-trimethoxycinnamate thymol ester to modulate these parameters and reverse senescence effects

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent introduces 3,4,5-trimethoxycinnamate thymol ester as an intermediary substance that mediates between UV exposure and melanocyte senescence, blocking the harmful effects of UV-induced senescence and restoring melanocyte function

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If UV exposure is increased for skin protection, then skin health is maintained, but melanocyte morphological changes and senescence are promoted

Engineering Contradiction:

Improveskin health maintenanceVSAvoidmelanocyte morphological changes

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent converts the harmful effect of UV exposure into a beneficial outcome by using 3,4,5-trimethoxycinnamate thymol ester to restore and protect melanocytes from UV-induced damage, transforming the harmful senescence process into a reversible state

Inventive Principle:

Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The patent applies preliminary anti-action by pre-treating melanocytes with 3,4,5-trimethoxycinnamate thymol ester before UV exposure or applying it continuously to prevent and reverse UV-induced morphological changes and senescence

Inventive Principle:

Principle #9Preliminary anti-action

AI summary

A composition capable of preventing or improving skin aging by controlling a senescence biomarker of melanocytes is disclosed. The composition includes a thymol ester-based compound as an effective ingredient, whereby when applied to a subject in which skin cells are flattened or enlarged, or β-galactosidase of melanocytes is activated, it can exhibit the effect of preventing or improving skin aging.
