Merocyanine and Ascorbic Acid Cosmetic Composition
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a challenge in finding cosmetic and dermatological compositions that effectively prevent and treat skin aging while maintaining good cosmetic properties, such as sensory feel and mechanical elasticity, particularly in reducing collagen degradation and improving skin elasticity.
Innovation Solution
A composition combining merocyanines of formula (I) with ascorbic acid and/or its derivatives, which enhances the production of procollagen and provides UVA-screening properties, thereby addressing skin aging and photo-aging signs effectively while maintaining a pleasant skin finish.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cosmetic compositions use high concentrations of active ingredients to effectively prevent and treat skin aging, then the anti-aging efficacy is improved, but the cosmetic properties such as sensory feel and skin finish deteriorate
Solution Approach 1:
The patent combines merocyanine compounds with ascorbic acid and its derivatives in a single cosmetic composition. This merging of multiple active ingredients with different mechanisms of action (UV filtration, collagen synthesis stimulation, antioxidant activity) allows the composition to achieve effective anti-aging results while maintaining good cosmetic properties, as each ingredient supports the others' functions.
Solution Approach 2:
The invention creates a composite cosmetic formulation integrating merocyanine UV filters, ascorbic acid derivatives, and auxiliary cosmetic ingredients. This composite structure enables the composition to simultaneously provide UV protection, stimulate procollagen production, and maintain pleasant sensory characteristics on the skin.
2Object-affected harmful factors
If cosmetic compositions focus on treating photo-aging signs, then the effectiveness against UV damage is improved, but the overall skin health and elasticity improvement is insufficient
Solution Approach 1:
The merocyanine compounds in the composition perform multiple functions: they act as UV filters to protect against photo-aging, while also contributing to the overall skin health improvement. The ascorbic acid derivatives simultaneously stimulate procollagen production, provide antioxidant protection, and improve skin elasticity, making the composition universally effective against multiple aging mechanisms.
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 combination effectively prevents and treats skin aging by stimulating procollagen production, improving skin elasticity and firmness, and reducing wrinkles and fine lines, while offering good cosmetic properties like reduced greasiness and tackiness.
Implementation Method 1
which enhances the production of procollagen and provides UVA-screening properties
Implementation Method 2
These compositions are preferentially intended for preventing and/or treating the signs of ageing of keratin materials such as the skin, and notably for increasing collagen synthesis
