8 Skin-Coat and Sebum System · 8.1 Sebaceous Synthesis and Release
8.1 Sebaceous Synthesis and Release
Feline Fat-Based Metabolism (Fat-Based Metabolism)
Sebaceous synthesis and release is the lipid generation and surface-release process within the skin-coat system.
In Feline FBM, sebaceous glands are not excretory organs.
They do not remove “extra fat,” “metabolic waste,” or “toxins” through the skin.
Their role is to synthesize lipids locally and release them into follicles and the skin surface to support barrier function, coat lubrication, and local environment maintenance.
Greasy coat, acne-like chin presentation, and follicle-state change cannot be explained as fat leaving through skin.
These outputs should backtrace to sebaceous synthesis and release state, Sebum Processing Rate, energy scheduling, Fat Processing Rate, Ingredient State, Fat Freshness Boundary, and Local Skin Environment.
This page belongs to the skin and sebum mechanism layer.
Sebaceous synthesis and release is mainly shaped by six variables.
Food structure changes Primary Energy Substrate, Insulin Regulation State, and the fatty acid oxidation pathway.
After energy scheduling changes, lipid synthesis and release in the skin-coat system may change.
When fatty acids become the primary energy substrate, the lipid background and energy state available to the skin system change.
This does not mean fat is released directly through skin.
It means sebaceous synthesis and release state changes after the system’s energy structure changes.
In Feline FBM, fat is a long-term primary energy substrate.
If Fat Freshness Boundary is unstable, digestive feedback, palatability, skin-coat output, and long-term stability may all shift.
Unstable Ingredient State—storage, microbial load, lipid damage—can change skin-coat output without proving “allergy.”
Follicle state, friction, humidity, licking, and local microbial conditions all affect sebum presentation.
True allergy, infection, parasites, or skin disease may exist.
They cannot serve as the default explanation for every greasy coat, rash, dermatitis, itching, or hair loss.
Oily feel on coat or localized skin, often at dorsum or tail base.
Comedone-like material or dark oxidation at chin; requires layered reading, not default folliculitis labeling.
Coat may look dull, clumped, or uneven when sebum processing rate and local environment shift together.
greasy coat = fat leaking through skin
greasy coat = detox pathway
acne-like chin = Malassezia root cause by default
cleaning alone = upstream food-structure judgment
Feline FBM is not a clinical diagnosis system, not a treatment protocol, and not an effect-guarantee system.
This page fixes sebaceous synthesis and release as a mechanism node in the skin-coat system, always readable back to upstream food structure.
