Solution Overview

Problem

Age-related skin color changes and uneven skin tone due to the accumulation of carbonylated proteins around skin pores, leading to yellowish or darker areas, are not effectively addressed by existing cosmetic and pharmaceutical treatments.

Innovation Solution

The use of compatible solutes, such as (S)-1,4,5,6-tetrahydro-2-methyl-4-pyrimidincarboxylic acid (ectoin) and (S,S)-1,4,5,6-tetrahydro-5-hydroxy-2-methyl-4-pyrimidincarboxylic acid (hydroxyectoin), to reduce protein carbonylation and the accumulation of carbonylated proteins in the stratum corneum, thereby lightening skin pores and improving skin tone.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If existing cosmetic and pharmaceutical treatments are used, then general skin care functions are maintained, but age-related skin color changes and uneven skin tone caused by carbonylated proteins are not effectively addressed

Engineering Contradiction:
Improveskin color changeVSAvoidtreatment effectiveness
Core Design Contradiction:
Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent introduces compatible solutes as intermediary substances that mediate between the harmful carbonylation process and the skin proteins. These solutes act as protective agents that intervene in the carbonylation reaction, preventing the formation of carbonylated proteins without directly altering the skin structure or requiring invasive procedures.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the chemical parameter environment by introducing compatible solutes that alter the local chemical conditions around skin proteins. This parameter change prevents the carbonylation reaction from proceeding, thereby addressing skin color changes through biochemical modification rather than physical removal or masking.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If compatible solutes are used, then protein carbonylation is reduced and skin tone is improved, but the mechanism of action differs from conventional treatments

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidtreatment mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent employs compatible solutes that enable the skin's own protective mechanisms to function more effectively. These solutes support the skin's natural ability to resist oxidative stress and protein damage, allowing the biological system to serve itself in combating carbonylation without requiring complex external intervention systems.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent converts the potentially harmful effect of oxidative stress into a beneficial outcome by using compatible solutes that enhance the skin's resistance to oxidation. The solutes transform the challenging environment of oxidative stress into an opportunity for improved skin protection and healthier skin tone.

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

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
