“Direct glutamic acid evidence: exogenous glutamic acid promoted keratinocyte viability/proliferation and topical application promoted hair growth in mice; skin-benefit scope is scalp/hair and epidermal cell proliferation.”
“Ingredient-family evidence: amino acids are key natural moisturizing factor components needed for stratum corneum hydration, barrier homeostasis, desquamation, and plasticity; applies to glutamic acid as an amino-acid/NMF-related ingredient, not necessarily isolated topical L-glutamic acid.”
“Ingredient-family evidence: natural moisturizing factor is a mixture of small water-soluble compounds in stratum corneum; extraction/removal affects skin molecular properties associated with dryness/brittleness, supporting amino-acid humectant relevance.”
