Soothing K-Beauty with Polyglutamic Acid features one of K-beauty's most effective hydrating ingredients. Polyglutamic acid (PGA) holds up to five times more moisture than hyaluronic acid, forming a smooth, hydrating film on the skin that locks in water and prevents evaporation. For reactive skin that is also dehydrated, PGA provides intense moisture retention alongside a soothing, protective feel.
How Polyglutamic Acid Hydrates Beyond Hyaluronic Acid
While hyaluronic acid draws water into the skin, polyglutamic acid works on the surface, creating a moisture-retaining film that prevents the hydration already in the skin from escaping. This makes PGA particularly effective in dry environments, heated rooms, or air-conditioned offices where trans-epidermal water loss is high. PGA also inhibits the enzyme hyaluronidase, which breaks down the skin's own natural hyaluronic acid. This means PGA both adds hydration and helps the skin keep its existing moisture stores intact. The combined effect is significantly plumper, more comfortable skin.
- Holds up to five times more moisture than hyaluronic acid
- Forms a moisture-retaining film on the skin surface
- Prevents trans-epidermal water loss in dry environments
- Inhibits hyaluronidase to protect natural hyaluronic acid
- Significantly plumper, more comfortable skin
The PGA Sensory Experience
PGA products have a slightly viscous, slippery texture that smooths across the skin and absorbs to a dewy, plump finish. The film-forming action leaves a subtle silky layer that makes the skin feel softer and smoother immediately after application. There is no stickiness or heaviness once absorbed. Products with PGA tend to make the skin look healthy and hydrated even before moisturiser is applied. The overall experience is immediately satisfying, which makes consistent use easy and enjoyable.

- Subtle silky feel on the skin surface
- Immediately gratifying hydration visible on application
PGA for Sensitive and Dehydrated Skin
Dehydrated skin that is also sensitive faces a particular challenge: it needs intense hydration, but many hydrating products contain fragrances or active ingredients that trigger reactivity. PGA is inherently gentle. It is a naturally occurring compound (found in fermented soybeans) with no irritation potential at cosmetic concentrations. Its film-forming action also acts as a mild protective barrier, shielding the skin from environmental irritants while keeping moisture locked in. For skin that stings when dry and reacts when treated, PGA offers hydration without compromise.

- Naturally occurring in fermented soybeans
- Protective film shields against environmental irritants
- Hydration without compromise for reactive skin
Using PGA in Your Routine
PGA serums and essences go in the treatment step after toner, before moisturiser. They work well in both morning and evening routines. In the morning, PGA creates a smooth, hydrated base for sunscreen and makeup. In the evening, it provides a moisture seal that supports overnight skin repair. PGA layers well with hyaluronic acid for a combined approach: hyaluronic acid pulls moisture in, PGA locks it at the surface. Compatible with all common K-beauty actives including niacinamide, vitamin C, and retinol.
