Fundamentals 2% Hyaluronic Acid Serum

Experience next-level hydration with our hyaluronic acid serum featuring 2% hyaluronic acid + polyglutamic acid. This powerful combo draws in deep moisture while sealing it on the surface for all-day plumpness, reduced fine lines, and a dewy glow. Hyaluronic acid penetrates to hydrate from within (holding up to 1,000x its weight in water), while polyglutamic acid (up to 4-5x more effective at moisture retention) forms a protective film to lock hydration in longer-preventing evaporation and boosting skin resilience.

Key Benefits:

Deep & Long-Lasting Hydration: Multi-layer moisture for plump, bouncy skin.

Plumps Fine Lines: Reduces dryness-induced wrinkles and improves elasticity.

Strengthens Barrier: Soothes dehydration, smooths texture, and enhances glow.

Smoother Texture & Glow - Calms dryness, evens tone, and enhances radiance.

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.

How to use:

After cleansing and applying a treatment tonic, apply 2-3 drops to damp skin for best absorption. Gently pat in, then follow with moisturiser or oil to seal. Use AM/PM daily-it's gentle, non-irritating, and layers beautifully under makeup or SPF. For extra boost, apply on slightly damp skin or mix with your favorite moisturiser.
