Photoactive Microalgae Extracts for Red-Light Collagen Stimulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-aging and anti-wrinkle cosmetic treatments do not effectively stimulate collagen synthesis and reduce oxidative stress in the skin, and healing processes are not adequately promoted by conventional methods.
Innovation Solution
A cosmetic method involving the application of photoactive microalgae extracts, such as Dunaliella salina and Tetraselmis suecica, followed by exposure to red light at 625-670 nm, particularly 645 nm, to enhance the production of reactive oxygen species (ROS) and nitric oxide, thereby increasing collagen synthesis and reducing pro-inflammatory cytokines and metalloproteinases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional anti-aging cosmetic treatments are applied, then skin care is provided, but collagen synthesis is not effectively stimulated and oxidative stress is not reduced
Solution Approach 1:
The patent changes the oxidation state parameter of the microalgae extracts from reduced to oxidized form through light exposure. This parameter change activates the extracts to stimulate collagen synthesis and reduce oxidative stress, resolving the contradiction between providing skin care and effectively stimulating collagen production
Solution Approach 2:
The patent converts the harmful effect of oxidative stress into a beneficial effect by using controlled oxidation of microalgae extracts. The oxidized extracts then act as antioxidants in the skin, reducing oxidative stress and stimulating collagen synthesis, thus turning potential harm into benefit
2Reliability
If conventional cosmetic treatments are applied, then skin healing is supported, but the healing process is not adequately promoted
Solution Approach 1:
The patent applies parameter change by oxidizing the microalgae extracts through light exposure, which activates their healing properties. The oxidized extracts then accelerate the skin healing process while providing reliable healing support, resolving the contradiction between supporting healing and adequately promoting the healing process
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 method significantly enhances skin elasticity, reduces wrinkles, and promotes healing by stimulating collagen production and cell regeneration, as demonstrated by clinical studies on 30 subjects.
