Amino acid, part of NMF. Humectant, supports stratum corneum hydration.
Topical application
BLimited evidence. One RCT or several controlled studies with limitations.
NMF component, safe.
Glutamic acid is a non-essential amino acid, a key component of the natural moisturizing factor (NMF) of the stratum corneum. Where applied. Moisturizing creams and serums, toners, hair products (0.5-5%). In NMF amino acid cocktails alongside pyrrolidone carboxylic acid, aspartic acid, serine, alanine, threonine. Also in cleansers – a gentle pH regulator. Evidence base. NMF amino acids in RCTs in dry skin and atopic dermatitis reduce TEWL and improve hydration (Verdier-Sevrain 2007). Few studies of glutamic acid alone; data come from the NMF amino acid mix. Safety. CIR confirmed safety. Hypoallergenic, non-comedogenic. Pregnancy and lactation – safe.
