Dehydroabietic Acid Skin Composition PPARα Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a growing need for compositions that strengthen the skin barrier and moisturize the skin, as environmental changes, lifestyle stress, and aging lead to skin dryness and barrier dysfunction.
Innovation Solution
A skin external application composition containing dehydroabietic acid, its isomers, precursors, salts, hydrates, or solvates, which activates peroxisome proliferator-activated receptor α (PPARα) and regulates gene expression to induce keratinocyte differentiation and enhance skin barrier formation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional skin care compositions are used, then basic moisturizing is achieved, but skin barrier strengthening and moisturization effects are insufficient due to environmental changes and aging
Solution Approach 1:
The patent changes the chemical parameter by introducing dehydroabietic acid as an active ingredient that activates PPARα, thereby changing the biological mechanism of action from conventional moisturizers to barrier-strengthening agents that regulate keratinocyte differentiation and lipid metabolism
Solution Approach 2:
The patent creates a composite skin care composition combining dehydroabietic acid with conventional skin care ingredients, forming a synergistic formulation that simultaneously provides barrier strengthening and moisturization effects
2Reliability
If dehydroabietic acid is used to activate PPARα and induce keratinocyte differentiation, then skin barrier strength is improved, but the complexity of the composition increases
Solution Approach 1:
The patent uses dehydroabietic acid as an intermediary substance that activates PPARα, which in turn regulates keratinocyte differentiation and lipid metabolism, creating a multi-step biological cascade that achieves barrier strengthening without requiring direct complex formulations

AI summary
The present disclosure relates to a skin external application composition comprising dehydroabietic acid, an isomer thereof, a precursor thereof, a salt thereof, a hydrate thereof, or a solvate thereof as an active ingredient for strengthening a skin barrier or moisturizing the skin. More specifically, the present disclosure relates to a skin external application composition that comprises dehydroabietic acid, an isomer thereof, a precursor thereof, a salt thereof, a hydrate thereof, or a solvate thereof to activate peroxisome proliferator-activated receptor alpha (PPAR α) in vivo to upregulate the expression thereof as well as the expression of filaggrin gene, transglutaminase 1 gene, and hyaluronic acid synthase 2 gene, whereby the composition induces the differentiation of skin keratinocytes, strengthens the skin barrier, and increases a skin water content.
