Dehydrated skin? Fine lines from dryness? Dull, tight complexion? Our advanced hydrating serum combines 2% hyaluronic acid with polyglutamic acid — a synergistic powerhouse that delivers superior, multi-level moisture unlike single-ingredient formulas. This lightweight, fast-absorbing serum is a game-changer for anyone seeking intense, long-lasting hydration, plumper appearance, and a strengthened skin barrier in hydration-focused routines.
2% Hyaluronic Acid: Deep Penetration for Inner Hydration
Hyaluronic acid (HA) is the gold-standard humectant, capable of holding up to 1,000 times its weight in water. At 2% — a potent yet gentle concentration often featured in top-rated serums — it draws moisture into deeper skin layers, plumping cells from within, improving elasticity, smoothing texture, and reducing the look of fine lines caused by dehydration. It enhances skin's natural flexibility, supports wound healing, and boosts overall softness and radiance. Dermatologists recommend HA for dry, mature, or environmentally stressed skin, as it visibly increases hydration levels (up to 96% in studies) and leaves skin feeling supple and bouncy.
Polyglutamic Acid: The Superior Moisture-Locking Hero
Polyglutamic acid (PGA), a peptide-derived humectant, takes hydration further by holding up to 4–5 times more water than HA and forming a breathable, protective film on the skin's surface. This "seals" in the moisture drawn by HA, preventing transepidermal water loss and extending hydration duration. PGA also boosts the skin's natural moisturizing factors, calms irritation, reduces redness, and improves barrier function—making it especially beneficial for dehydrated, flaky, or sensitive skin. Experts note PGA's larger molecular size allows it to sit on top and lock moisture longer, creating a smoother, dewier finish while enhancing elasticity and plumpness.
Why This Combination Outperforms Single Hydrators
Hyaluronic acid pulls water in → polyglutamic acid locks it → together they create full-spectrum hydration: deep replenishment + surface protection.
Clinical insights and user reports show this pairing provides superior results for dry, dehydrated, or aging skin compared to HA alone—often with noticeable plumpness and softness in days, and cumulative improvements over weeks.
