Viniferine Topical Compositions for Blue-Light Hyperpigmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic compositions do not effectively target hyperpigmentation caused by exposure to blue light, which stimulates melanin production and has harmful effects on the skin.
Innovation Solution
The use of viniferine, a resveratrol oligomer with stabilized hydroxyl groups, in the form of ether or ester, to prevent, reduce, or erase damage from blue light exposure, including hyperpigmentation, through topical application in cosmetic compositions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If conventional cosmetic compositions with photo-protective molecules are used, then skin protection from blue light is provided, but hyperpigmentation caused by blue light exposure is not effectively targeted
Solution Approach 1:
The patent transforms the chemical structure of resveratrol by converting its hydroxyl groups into ether or ester groups, creating viniferine with enhanced stability and specific activity against blue light-induced hyperpigmentation. This parameter change in molecular structure resolves the contradiction by providing both stability and targeted efficacy.
Solution Approach 2:
The patent uses viniferine as a composite active ingredient that combines the photoprotective properties of resveratrol derivatives with enhanced stability. This composite approach allows the composition to effectively target hyperpigmentation while maintaining reliability against blue light damage.
2Reliability
If hydroxyl groups of resveratrol are used for photoprotection, then anti-oxidant and anti-radical activity is provided, but stability in air and light is compromised
Solution Approach 1:
The patent chemically modifies resveratrol by converting unstable hydroxyl groups into stable ether or ester groups. This parameter change in functional group chemistry resolves the contradiction by maintaining the photoprotective and anti-oxidant activities while dramatically improving stability in air and light conditions.
