This facial serum from NEEDS NATURE contains 10% polyglutamic acid, a peptide-like ingredient known for its ability to hold moisture on the skin's surface. Combined with hyaluronic acid and allantoin, the formula aims to support hydration and soothe dryness. Polyglutamic acid, derived from fermented soybeans, is often used in Korean skincare for its water-binding properties, which can help maintain a plump appearance without a heavy feel.

The serum is designed as a DIY hydrating booster, meaning it can be incorporated into existing routines—applied alone or mixed with moisturizers for an extra layer of moisture. Allantoin is included to gently calm irritated or sensitive skin, making the product suitable for dry and reactive skin types. The lightweight, water-like texture allows for quick absorption without leaving a sticky residue, which is particularly beneficial in humid conditions or under makeup.

This 30ml bottle offers a concentrated yet gentle approach to daily hydration. The formula is free from artificial fragrances and dyes, reducing the likelihood of irritation. It is best suited for those seeking a simple, effective way to boost skin moisture levels without introducing unnecessary additives. The product is produced under Korean skincare standards, emphasizing balanced hydration and skin barrier support. For optimal results, it can be used morning and evening after cleansing, followed by a moisturizer if needed.
