Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is an unmet need for compositions that slow down or reduce the signs of sensitive skin aging, as existing anti-aging products can irritate sensitive skin and accelerate aging.

Innovation Solution

A personal care composition comprising niacinamide, Edelweiss (Leontopodium alpinum) extract, rice (Oryza sativa) lees concentrate, panthenol, and soy-derived glycopeptides, which does not include retinoid or retinoid derivatives, is administered to treat sensitive skin.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Shape

If retinoids are used in anti-aging lotions to stimulate collagen synthesis and reduce wrinkles, then wrinkle reduction is improved, but skin irritation increases making sensitive skin more sensitive

Engineering Contradiction:

Improvewrinkle reductionVSAvoidskin irritation

Core Design Contradiction:

ShapeVSObject-affected harmful factors

Solution Approach 1:

The patent removes retinoids from the formulation entirely, extracting the problematic ingredient that causes irritation while seeking alternative anti-aging actives that do not compromise skin barrier integrity in sensitive skin types

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the chemical composition parameters by replacing retinoid-based formulations with a specific combination of niacinamide, Edelweiss extract, rice lees concentrate, panthenol, and soy-derived glycopeptides, achieving anti-aging effects through different biochemical mechanisms that are gentler on sensitive skin

Inventive Principle:

Principle #35Parameter changes

2Duration of action of stationary object

If conventional anti-aging ingredients are used to slow down skin aging, then aging signs are reduced, but skin sensitivity and irritation are exacerbated

Engineering Contradiction:

Improveskin aging progressionVSAvoidskin sensitivity

Core Design Contradiction:

Duration of action of stationary objectVSObject-affected harmful factors

Solution Approach 1:

The patent introduces niacinamide as a key intermediary ingredient that supports skin barrier function and reduces sensitivity while providing anti-aging benefits, acting as a mediating substance that protects against environmental challenges without causing irritation

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates a composite formulation combining multiple gentle ingredients (Edelweiss extract, rice lees concentrate, panthenol, soy-derived glycopeptides) that work synergistically to provide anti-aging protection without the harsh effects of conventional single-ingredient or retinoid-based products

Inventive Principle:

Principle #40Composite materials

AI summary

Provided herein are personal care compositions for reducing the signs of aging in sensitive skin without the irritating effects associated with retinol. Such personal care compositions comprise niacinamide, Leontopodium alpinum extract, Oryza sativa lees extract, panthenol, and soy-derived glycopeptides. Use of such compositions also modulates some biochemical indicators that are associated with premature aging of skin in response to pollution.
