JAKARTA – Innovations in the beauty industry respond to consumer needs, including finding effective skincare ingredients to deal with dry skin caused by a number of factors. Both the increasing age and the air with low humidity causing dry skin, is claimed to be overcome with an ingredient extracted from natural ingredients, called polyglutamic acid or polyglutamic acid.

Renee Lapono, a facial care expert reported by Vogue, Monday, December 6, said that polyglutamic acid is able to maintain skin moisture five times more potent than hyaluronic acid or hyaluronic acid. In addition, skin that feels tired from being exposed to hot, dry air, and through winter needs perfect care.

Polyglutamic acid comes from natt, a Japanese food made from fermented soybeans. As a peptide, polyglutamic acid is able to inhibit the production of hyaluronidase. Hyaluronidase is an enzyme that breaks down the skin's natural hyaluronic acid as we age and causes the skin to lose moisture.

Polyglutamic acid consists of large molecules that form a thin film on the surface of the skin. This layer prevents water loss and encourages the skin's natural moisturizing process. Another positive effect is that it reduces fine lines and brightens the skin, adds Lapino.

Dermatologist Sam Bunting, adds that polyglutamic acid is not a substitute for pre-existing ingredients, such as hyaluronic acid and retinol. Polyglutamic acid is a great addition to hydrating the skin and can work effectively with vitamin C.

Lapino's advice, skincare products with a single content of polyglutamic acid should be used last. If you use several types of serum, use this last one.

Lapino says, after cleansing, apply a product with hyaluronic acid to hydrate and buffer antioxidants like vitamin C. Or use an exfoliating serum with glycotic acid, after fully absorbed, then put on a polyglutamic acid serum and cover with a cream containing SPF for your morning routine.
