Oestrogen
MolecularEntityA steroid sex hormone acting directly on dermal fibroblasts and epidermal keratinocytes to regulate collagen synthesis, ceramide production, hyaluronic acid content, and barrier integrity.
-
Oestrogen decline
BiologicalProcessThe progressive reduction in oestrogen that begins in the early 40s and accelerates through perimenopause into menopause, driving simultaneous changes across the dermis, epidermis, and skin barrier.
-
Oleic acid
MolecularEntityAn 18-carbon monounsaturated omega-9 fatty acid abundant in olive oil, tallow, and sebum. Plays a role in membrane fluidity and skin feel.
-
Omega-3 fatty acids
ChemicalSubstanceEssential fatty acids with anti-inflammatory properties, supporting barrier function and skin health when consumed in adequate amounts.
-
Omega-6 fatty acids
ChemicalSubstanceEssential fatty acids that promote inflammation when consumed excessively relative to omega-3s, common in modern Western diets.
-
Oxidative phosphorylation
BiologicalProcessOxidative phosphorylation generates the bulk of cellular ATP in mitochondria, coupling oxygen use to energy production while also producing ROS, a process central to tissue function and ageing.
