Cosmetic Composition Reinforcing Epidermal Tight Junctions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current treatments for atopic dermatitis often involve undefined compositions of plant extracts and bacterial lysates, which can cause allergic or inflammatory reactions and vary significantly in composition, necessitating a need for a composition that restores tight junction functionality in the skin using pure, safe, and biomimetic active compounds.
Innovation Solution
A cosmetic composition comprising biomimetic compounds such as basic amino acids like arginine and glycosylceramides, which synergistically induce the expression of claudin-1, a key structural protein of tight junctions, to improve skin barrier function and treat atopic dermatitis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plant extracts and bacterial lysates are used to treat atopic dermatitis, then skin barrier function can be improved, but allergic or inflammatory reactions may occur and composition consistency varies
Solution Approach 1:
The patent extracts and isolates specific pure compounds (glycosylceramides and basic amino acids) from complex natural sources, separating the beneficial active ingredients from potential allergens and inconsistent components. This extraction process maintains the therapeutic effect while eliminating harmful variability and allergic potential.
Solution Approach 2:
The patent changes the chemical purity parameter of the active ingredients by providing highly purified forms of glycosylceramides and basic amino acids with defined chemical structures and compositions. This parameter change from crude extracts to purified compounds ensures consistency and safety while maintaining efficacy.

3Reliability
If tight junction expression is increased to restore skin barrier, then atopic dermatitis can be treated, but safe and biomimetic compounds are needed
Solution Approach 1:
The patent uses biomimetic compounds that replicate or mimic the natural constituents found in human skin (glycosylceramides and amino acids). These copied molecular structures are naturally compatible with skin biology, ensuring safety while effectively restoring tight junction function and barrier integrity.
