GLUTAMIC ACID

Description

Glutamic acid is a non-essential amino acid that plays a crucial role in skin health and cosmetic formulations. This multifunctional ingredient acts as a natural moisturizing factor (NMF) in the skin, helping to maintain hydration and improve barrier function. Glutamic acid's hygroscopic properties allow it to attract and retain moisture, making it an effective humectant in skincare products.

In addition to its hydrating capabilities, glutamic acid contributes to the skin's pH regulation, helping to maintain the acid mantle and protect against environmental stressors. It also supports the synthesis of other important skin components, such as collagen and hyaluronic acid, which are essential for maintaining skin elasticity and firmness.

Glutamic acid's gentle exfoliating properties make it valuable in addressing hyperpigmentation and uneven skin tone. It can help to promote cell turnover and improve overall skin texture. In skincare formulations, glutamic acid is often used in concentrations ranging from 0.1% to 3%, depending on the product's intended function and target concerns. Its compatibility with various skin types and low risk of irritation make it a versatile ingredient in moisturizers, serums, and anti-aging products.
