SCFA Culture Medium for Dry Skin Sebum Stimulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic agents for treating dry and aged skin, particularly hyposeborrheic dry skin, face stabilization issues due to biomass sedimentation and do not effectively stimulate sebum production.
Innovation Solution
Utilizing a conditioned culture medium from Propionibacterium acnes containing short chain fatty acids (SCFA) with 3 to 8 carbon atoms, such as propionate, butyrate, and valerate, to enhance sebum synthesis and secretion, optionally combined with long chain fatty acids (LCFA) for boosted sebogenic response.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biomass of bacteria is used as active agent, then prevention and treatment of dry skin is achieved, but stabilization problems occur due to phase separation induced by sedimentation
Solution Approach 1:
The invention extracts the active principle (short chain fatty acids) from the bacterial biomass and uses it in the form of culture supernatant or purified extract, thereby eliminating the sedimentation and phase separation problems associated with whole biomass while retaining the beneficial sebogenic effects
Solution Approach 2:
The culture supernatant acts as an intermediary medium that carries the active short chain fatty acids from the bacterial culture to the skin, providing a stable liquid vehicle that avoids the stabilization issues of direct biomass application
2Reliability
If conventional cosmetic agents are used, then skin comfort is maintained, but effective stimulation of sebum production is not achieved
Solution Approach 1:
The invention changes the chemical parameter of the cosmetic composition by introducing specific short chain fatty acids (propionate, butyrate, valerate) with 3-8 carbon atoms, which have been shown to specifically stimulate sebocyte proliferation and sebum production, thereby enhancing the sebogenic response beyond conventional agents
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 SCFA and LCFA combination effectively prevents and treats dry and aged skin by increasing sebum production, addressing hyposeborrheic conditions and improving skin comfort and aesthetics.
Implementation Method 1
the use of a conditioned culture medium obtained from at least one microorganism of the species Propionibacterium acnes, the said medium comprising at least one short chain fatty acid
