Personal Care Formulation With AHA, BHA, and PHA Exfoliation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing personal care products fail to effectively exfoliate the stratum corneum to promote cell regeneration and improve skin tone, often leaving visible scars and causing discomfort.
Innovation Solution
A personal care formulation combining alpha hydroxy acids, beta hydroxy acids, and polyhydroxy acids, specifically in defined weight ratios, to gently exfoliate the skin and enhance skin smoothness without visible scarring, using ingredients that mitigate stinging and provide anti-inflammatory benefits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If traditional exfoliating products are used to remove dead skin cells, then skin smoothness is improved, but visible scars and discomfort are caused
Solution Approach 1:
The patent changes the chemical parameters by using a specific combination of alpha hydroxy acids (AHAs), beta hydroxy acids (BHAs), and polyhydroxy acids (PHAs) in defined weight ratios. This parameter change allows effective exfoliation while minimizing harmful effects like scarring and discomfort, as the specific acid combination and ratios provide controlled chemical peeling action.
Solution Approach 2:
The patent employs a composite formulation combining multiple types of acids (AHAs, BHAs, and PHAs) working synergistically. This composite approach enables comprehensive exfoliation benefits while the combined formula mitigates the harmful effects of individual acids, reducing scarring and discomfort through the balancing action of different acid types.
2Illumination intensity
If higher concentrations of exfoliating acids are used to enhance cell regeneration, then skin brightness is improved, but stinging and pain sensation increase
Solution Approach 1:
The patent optimizes the concentration parameters by establishing specific weight ratios between different acid types. The formulation maintains effective brightness-enhancing exfoliation through the synergistic acid combination while controlling the overall刺激性 to minimize stinging and pain, avoiding the need for excessively high concentrations of any single acid.
Solution Approach 2:
The patent introduces soothing and anti-inflammatory agents as intermediary components that mediate between the exfoliating acids and the skin. These intermediary substances reduce the harmful effects of the acids on skin nerves and tissues, allowing higher effective concentrations for brightness while suppressing stinging and pain sensations.
3Productivity
If aggressive exfoliation is applied to remove dead skin buildup, then skin regeneration is accelerated, but skin barrier integrity is compromised
Solution Approach 1:
The patent changes the chemical action parameters by using a balanced combination of acid types with different mechanisms. AHAs provide surface exfoliation, BHAs penetrate deeper, and PHAs offer gentle exfoliation with barrier support. This parameter balance accelerates cell regeneration while preserving skin barrier integrity through the coordinated action of different acid mechanisms.
Solution Approach 2:
The patent ensures continuous skin barrier support during the exfoliation process by incorporating ingredients that maintain barrier integrity throughout the treatment. The formulation provides continuous beneficial action by combining exfoliation with barrier reinforcement, allowing accelerated regeneration without compromising the protective skin barrier function.
