Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current topical dermatological compositions fail to effectively protect skin from oxidative damage caused by UV radiation and intrinsic aging, with existing antioxidants like vitamin E degrading into pro-oxidative products and providing insufficient protection.
Innovation Solution
Topical compositions containing PQQ esters in combination with superoxide dismutase and/or catalase, which act as potent free radical scavengers, neutralizing oxidative stress and promoting mitochondrial biogenesis, cellular respiration, and skin regeneration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional antioxidants like vitamin E are used to protect skin from oxidative damage, then some protection is provided, but they degrade into pro-oxidative products and provide insufficient protection
Solution Approach 1:
The patent changes the chemical structure parameter of antioxidants by using PQQ esters instead of conventional antioxidants like vitamin E. PQQ esters possess enhanced stability and antioxidant capacity, preventing degradation into pro-oxidative products while maintaining protective function against UV-induced oxidative damage.
Solution Approach 2:
The patent combines PQQ esters with other antioxidants and skin care ingredients to create a composite formulation. This composite approach synergistically enhances protection effectiveness while the stable PQQ ester backbone prevents the formation of harmful pro-oxidative degradation products.
2Object-affected harmful factors
If existing antioxidant compositions are used, then some oxidative protection is provided, but they fail to effectively protect skin from UV radiation and intrinsic aging damage
Solution Approach 1:
The patent enhances the antioxidant capacity parameter by introducing PQQ esters, which have superior electron-donating ability and radical scavenging activity compared to conventional antioxidants. This structural parameter change enables effective protection against both UV radiation and intrinsic aging-induced oxidative damage.
Solution Approach 2:
PQQ esters act as intermediary molecules that transfer electrons to neutralize free radicals generated by UV radiation and metabolic processes. Their stable structure allows them to function as effective mediators without degrading into harmful substances, providing reliable protection against oxidative damage.
3Reliability
If PQQ esters are used to provide potent free radical scavenging, then enhanced antioxidant effectiveness and mitochondrial protection are achieved, but the composition complexity increases
Solution Approach 1:
PQQ esters serve multiple functions simultaneously: they scavenge free radicals, protect mitochondrial membranes, support cellular respiration, and promote skin cell regeneration. This multi-functionality reduces the need for multiple separate ingredients, thereby managing composition complexity while enhancing antioxidant effectiveness.
Solution Approach 2:
The patent merges the functions of multiple antioxidants and mitochondrial supporters into a single PQQ ester molecule. This consolidation achieves enhanced antioxidant effectiveness without proportionally increasing composition complexity, as PQQ esters provide coordinated protection across multiple biological targets.
