Solution Overview

Problem

High levels of retinol or retinaldehyde in cosmetic products can cause undesirable skin side effects such as irritation, redness, and sensitivity, limiting their effectiveness for anti-aging benefits.

Innovation Solution

A cosmetic composition comprising a high potency level of retinoid, extract of Centella asiatica, and a dipeptide, which reduces skin sensitivity and minimizes adverse effects while maintaining anti-aging benefits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If high levels of retinol or retinaldehyde are used in cosmetic products, then anti-aging benefits are improved, but skin irritation and sensitivity increase

Engineering Contradiction:

Improveanti-aging effectivenessVSAvoidskin irritation and sensitivity

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent uses Centella asiatica extract as an intermediary substance that mediates between the retinol/retinaldehyde and the skin. This extract contains triterpenes and other bioactive compounds that reduce skin irritation and sensitivity caused by high levels of retinoids, while allowing the anti-aging benefits to be maintained. The intermediary protects the skin from harmful effects without interfering with the therapeutic action of retinol.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a composite cosmetic formulation that combines retinol or retinaldehyde with Centella asiatica extract and other complementary ingredients. This composite approach allows the product to deliver both the anti-aging benefits of retinoids and the skin-soothing properties of Centella asiatica, resolving the contradiction between effectiveness and tolerability.

Inventive Principle:

Principle #40Composite materials

2Productivity

If high potency retinoid levels are applied, then skin renewal and regeneration are enhanced, but adverse skin effects such as redness and peeling increase

Engineering Contradiction:

Improveskin renewal rateVSAvoidredness and peeling

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent converts the potentially harmful effects of high potency retinoids into beneficial outcomes by using Centella asiatica extract to manage the adverse reactions. The extract reduces inflammation and supports skin barrier function, allowing the skin to tolerate higher retinoid levels that drive renewal, thereby converting what would be harmful irritation into controlled, beneficial exfoliation and regeneration.

Inventive Principle:

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

Solution Approach 2:

The patent modifies the formulation parameters by incorporating specific concentrations of Centella asiatica extract and adjusting the ratio of retinoid to soothing ingredients. This parameter optimization allows the product to achieve effective skin renewal while maintaining skin comfort and minimizing visible adverse effects like redness and peeling.

Inventive Principle:

Principle #35Parameter changes
