The Ordinary published a June 22, 2026, article explaining Natural Moisturising Factors, their role in skin hydration and barrier function, and how its products aim to support NMF levels.

The article defined Natural Moisturising Factors as water-attracting compounds in the skin’s outermost layer that help maintain hydration. It said NMFs include free amino acids, PCA, sodium lactate, urea, sugars and minerals.

It stated NMFs supported hydration, elasticity, barrier function, cell renewal and pH balance. It said low NMF levels were associated with dryness, irritation, fine lines, reduced elasticity and greater sensitivity to environmental stressors.

The article said aging, over cleansing, over-exfoliation, low humidity, cold weather and UV exposure could deplete NMFs. It recommended avoiding stripping cleansers and over-exfoliation to help maintain moisture balance.

The Ordinary highlighted its Squalane Cleanser, Amino Acids + B5, Natural Moisturizing Factors + HA and Natural Moisturizing Factors + PhytoCeramides as products designed to support hydration and barrier function. It also advised daily broad-spectrum SPF and consistent use of hydrating, barrier-supporting products.
