Natural moisturizing factor is known to contain what?

Natural moisturizing factor (NMF) is primarily composed of amino acids, along with other components such as sugars and urea. Amino acids play a crucial role in maintaining skin hydration by attracting and binding water molecules, effectively helping to keep the skin moisturized and supple. The presence of these essential building blocks contributes significantly to the skin's barrier function and overall health.

While sugars, proteins, and fatty acids have their own roles in skin health and may contribute to skin hydration in various ways, amino acids are specifically recognized as a vital part of the NMF, which is naturally found in the stratum corneum, the outermost layer of the skin. This factor is essential for skin softness and moisture retention, making the understanding of amino acids in this context particularly important for skincare and dermatological studies.
