Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing topical formulations fail to adequately address multiple skin concerns such as skin lightening, dark spot reduction, anti-inflammatory properties, skin retexturing, and protection against harmful microbiomes, often causing instability and irritation.
Innovation Solution
A skincare formula combining acetyl zingerone, azelaic acid, bakuchiol, licorice extract, and vitamin C or derivatives, along with a silicone-based additive, designed to synergistically target these concerns with careful consideration of ingredient interactions, texture, and molecular sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple active ingredients are combined to address multiple skin concerns, then skin improvement effectiveness is enhanced, but formulation stability deteriorates
Solution Approach 1:
The patent combines multiple active ingredients (azelaic acid, bakuchiol, vitamin C, licorice extract, acetyl zingerone) with distinct functions into a single topical formulation. Each ingredient targets different skin concerns: azelaic acid for acne and hyperpigmentation, bakuchiol for anti-aging, vitamin C for antioxidant protection and brightening, licorice extract for tyrosinase inhibition, and acetyl zingerone for antioxidant and anti-inflammatory effects. This merging allows one product to address multiple skin concerns simultaneously while maintaining formulation stability through careful compatibility assessment and pH control.
Solution Approach 2:
The formulation uses a composite approach by combining ingredients with different chemical properties and mechanisms of action. The base formulation includes silicone-based additives for texture and stability, along with the active ingredients in optimized concentrations. This composite structure ensures that each component contributes its specific benefits while the overall formulation remains stable and compatible, preventing ingredient interactions that would compromise effectiveness.
2Adaptability or versatility
If multiple active ingredients are combined to address multiple skin concerns, then comprehensive skin care is improved, but skin irritation increases
Solution Approach 1:
The patent carefully controls the concentration parameters of each active ingredient to minimize irritation while maintaining effectiveness. Azelaic acid is formulated at 10-20%, bakuchiol at 0.1-1%, vitamin C at 5-20%, licorice extract at 1-10%, and acetyl zingerone at 0.1-1%. These parameter optimizations ensure that each ingredient works at effective levels without causing excessive irritation. Additionally, the formulation maintains a controlled pH level to enhance stability and reduce potential irritation from acidic components.
Solution Approach 2:
The formulation includes soothing and anti-inflammatory ingredients that act as intermediaries to buffer potential irritation from the active components. Licorice extract and acetyl zingerone provide anti-inflammatory effects that can mitigate irritation from azelaic acid and vitamin C. The silicone-based additives also serve as intermediaries by providing a gentle base that reduces direct skin contact irritation while maintaining product efficacy.
3Reliability
If ingredient concentrations are increased to enhance effectiveness, then skin improvement results are improved, but ingredient stability deteriorates
Solution Approach 1:
The patent optimizes the concentration parameters of each active ingredient to achieve the desired skin improvement results while maintaining ingredient stability. Vitamin C is formulated at 5-20% in a pH-controlled environment to prevent oxidation and degradation. Azelaic acid is used at 10-20%, a concentration that provides therapeutic benefits while remaining stable in the formulation. Bakuchiol is included at 0.1-1% to ensure effectiveness without compromising stability. These parameter optimizations balance efficacy and stability for long-term product performance.
