It also influences our skin's natural acid mantle and pH, which protects our skin from harmful bacteria.
Our NMF is formed from amino acids, lactic acid, sugars, minerals, peptides, and electrolytes. As we age, our NMF naturally depletes. Other sources of NMF depletion include harsh and drying ingredients such as denatured alcohol. Sodium lactate can help replenish our NMF, leading to more hydrated and plump skin.
