Topical Antioxidant Composition for Skin Oxidative Stress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current skin care products are inadequate in effectively addressing oxidative stress and free radical damage, leading to skin aging, inflammation, and cellular breakdown, with existing antioxidants often causing side effects when administered orally.
Innovation Solution
A novel cosmetic composition combining synergistic antioxidant ingredients from Lycium barbarum, Punica granatum, Vitis vinifera, Aspalathus linearis, and Camellia Sinensis, applied topically to reduce oxidative stress, promote skin health, and enhance appearance, while minimizing side effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antioxidants are administered orally, then free radical damage is reduced, but side effects occur
Solution Approach 1:
The patent uses topical application as an intermediary route of administration, delivering antioxidants directly to the skin through cosmetic formulations rather than systemic oral administration. This localized delivery method reduces side effects while maintaining effectiveness at the target site.
Solution Approach 2:
The patent changes the parameter of administration route from oral to topical, and optimizes antioxidant concentration in cosmetic formulations (0.01-20% by weight) to achieve effective free radical scavenging while minimizing side effects through localized rather than systemic exposure.
2Reliability
If existing antioxidants are used, then free radical damage is addressed, but they are inadequate in effectively reducing oxidative stress
Solution Approach 1:
The patent combines multiple antioxidant compounds (vitamin C, vitamin E, ferulic acid, green tea extract, resveratrol) into a synergistic formulation, where each component enhances the effectiveness of others, thereby improving overall oxidative stress reduction and aesthetic benefits compared to single antioxidants.
Solution Approach 2:
The patent creates a composite antioxidant system comprising multiple different antioxidant compounds with complementary mechanisms of action, forming a more effective and comprehensive protective system against free radical damage than individual antioxidants alone.
3Reliability
If antioxidants are applied topically, then free radical damage is prevented, but delivery effectiveness is insufficient
Solution Approach 1:
The patent uses cosmetic formulation components (emollients, surfactants, pH adjusters) as intermediaries to facilitate the delivery and penetration of antioxidant compounds through the skin, improving bioavailability and effectiveness of topical antioxidant application.
Solution Approach 2:
The patent optimizes parameters including pH, concentration (0.01-20% by weight), and formulation composition to enhance the stability, penetration, and delivery effectiveness of antioxidants through topical application, ensuring adequate delivery to achieve free radical scavenging in skin tissues.
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
The composition effectively reduces oxidative stress, inflammation, and skin damage, promoting a youthful and resilient appearance by enhancing the skin's natural antioxidant defenses and reducing the appearance of aging signs without significant side effects.
Implementation Method 1
antioxidants have the ability to donate electrons to a free radical without themselves forming a free-radical, thus, breaking the damaging chain reaction
Implementation Method 2
Free radical scavengers or antioxidants are known to help reverse and prevent free radical damage. When applied topically to the skin, antioxidants interact with free radicals in the tissues in such a way as to render them harmless

AI summary
Antioxidant cosmetic skin care compositions formulated to combat conditions associated with free radical damage and oxidative stress are provided. The compositions contain effective amounts of one of several active agents, including an agent derived from one or more of the plant species: Lycium barbarum, Punica granatum, Vitis vinifera, Aspalathus linearis, and Camellia Sinensis as well as cosmetically acceptable carriers. These cosmetic compositions find use in improving the appearance of aged or damaged skin.
