An NMF (natural moisturizing factor) is an essential type of structural molecule that’s found in your skin. Their roles? To maintain skin hydration. This is it, in its literal most simplest terms. Amino acids, lactic acid, etc are NMFs which are essential moisturizing molecules that are found in your skin, which is why they’re also found in skin care products.
Why are they important?
The NMFs, through hydration:
- maintain plasticity of the skin to protect it from damage
- contribute to optimized barrier function
- allow for enzymes to function more optimally in the exfoliation process of the skin
