What they are
Natural Moisturising Factors (NMFs) are a collection of water-binding molecules found in the outer layer of the skin. They include amino acids, urea, lactates, sugars, and electrolytes, which are all essential to maintaining healthy hydration levels. NMFs are produced naturally as part of the skin’s renewal process and help it remain soft, smooth, and resilient.
How it works in skincare and body care
NMFs attract and hold water within the outermost layers of the skin, ensuring flexibility and preventing dryness. When the barrier is compromised through harsh cleansing, ageing, or environmental stress, NMF levels drop, leading to dehydration, flaking, and discomfort.
Skincare products that contain or replenish NMFs, such as hydrating creams and serums, restore balance and improve barrier function. In hand and body care, where repeated washing and exposure can strip moisture, using products that focus on replenishing NMFs helps protect against roughness and irritation. Supporting these natural molecules is key to maintaining smooth, comfortable, and well-hydrated skin that feels as healthy as it looks.
