Fatty acids
ChemicalSubstanceFatty acids are the molecular building blocks of dietary and bodily fats. They vary by chain length, degree of saturation, and double bond position.
-
Ferritin
ProteinFerritin stores and releases iron; the most sensitive marker of low iron availability, with fatigue and cognitive drag often emerging when levels fall below ~50 µg/L despite 'normal' lab ranges.
-
Fibroblast
AnatomicalStructureDermal connective tissue cells that synthesise collagen, elastin, hyaluronic acid, and the broader extracellular matrix.
-
Fibroblast growth factor
ProteinA family of 22 signalling proteins acting through tyrosine kinase receptors to regulate fibroblast proliferation, collagen synthesis, keratinocyte migration, and angiogenesis.
-
Filaggrin
ProteinBarrier protein that collapses keratinocytes into corneocytes and then degrades into natural moisturising factor. Suppressed by inflammation during barrier dysfunction.
-
Food addiction
MedicalConditionCompulsive eating pattern with addiction-like features including tolerance, withdrawal, and loss of control; distinct from restriction-induced issues.
-
Free fatty acids
ChemicalSubstanceBarrier lipids comprising 15–25% of the stratum corneum matrix. Beyond structural support, they generate the skin's acidic pH.
