Summary

Natural Moisturizing Factors (NMFs) are a collection of water-soluble compounds found naturally in the skin's outermost layer, the stratum corneum. These substances, including amino acids, urea, and lactic acid, are crucial for maintaining skin hydration, plasticity, and barrier function. Topical application of products containing NMFs helps replenish these vital humectants, which decline with age, thereby improving skin hydration, reducing transepidermal water loss (TEWL), and mitigating signs of skin aging like fine lines and dullness.

Purpose

Topically replenishes skin's natural humectants for improved hydration and barrier function.

Card Summary

Topical humectants that hydrate skin and support barrier function.
