Lycium chinense and Pine Needle Extract for Retinoic Acid Receptor Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-aging skin treatments using tretinoin and retinol are limited by low absorbability, instability, skin irritation, and side effects, necessitating additional stabilization measures, while seeking natural alternatives that activate retinoic acid receptor without adverse effects.
Innovation Solution
A skin external composition combining Lycium chinense fruit extract and pine needle extract, which activates retinoic acid receptor and inhibits collagenase expression, offering wrinkle-reducing and anti-aging effects with reduced side effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If tretinoin is used as a main component for anti-aging treatment, then anti-aging effect is improved, but skin irritation and side effects increase
Solution Approach 1:
The patent uses retinol as an intermediary substance that can be converted to retinoic acid in the body, avoiding direct application of irritating tretinoin while still achieving anti-aging effects through RAR activation
Solution Approach 2:
The patent changes the chemical parameter from tretinoin (all-trans-retinoic acid) to retinol (vitamin A), which has different stability and irritation properties, allowing anti-aging activity with reduced side effects
2Reliability
If retinol is used for anti-aging treatment, then anti-aging effect is improved, but stability deteriorates
Solution Approach 1:
The patent combines retinol with antioxidants (BHT, di-α-tocopherol, BHA, ascorbic acid, tocopheryl linolate) to create a composite formulation that stabilizes retinol against degradation from light, oxygen, heat, and lipid peroxides
3Reliability
If tretinoin is applied to skin, then anti-aging effect is improved, but absorbability decreases
Solution Approach 1:
The patent changes the chemical form from fat-soluble tretinoin to retinol, which can be incorporated into lipid-based delivery systems like liposomes and capsules, improving skin penetration and absorbability
4Stability of the object's composition
If additional stabilizing measures are taken for retinol, then stability is improved, but device complexity increases
Solution Approach 1:
The patent uses antioxidants as intermediary substances that protect retinol from degradation without requiring complex formulation systems, simplifying the overall stability approach
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 composition effectively inhibits collagenase expression and promotes collagen production, providing significant anti-aging benefits with enhanced safety and stability, suitable for cosmetic and pharmaceutical applications.
Implementation Method 1
a skin external composition containing a mixture of extracts of Lycium chinense fruits and pine needles that are natural materials has an excellent effect on the prevention of skin aging by activating retinoic acid receptor
