Isntree Ultra-Low Molecular Hyaluronic Acid Serum 50ml

14 layers of ultra-low molecular hyaluronic acid with Ulleung Island seawater: hydration that reaches deeper.

The Isntree Ultra-Low Molecular Hyaluronic Acid Serum contains 14 layers of ultra-low molecular weight hyaluronic acid alongside fresh seawater from Ulleung Island. Because smaller HA molecules penetrate further than standard hyaluronic acid, this works on dehydration from within rather than only sitting on the surface: giving a firmer, plumper look with a lightweight finish.

Key Benefits

• 14 layers of ultra-low molecular weight hyaluronic acid for deep hydration
• Fresh Ulleung Island seawater: supports mineral-rich moisture
• Firming-style hydration: supports a plumper, bouncier look
• Lightweight texture: absorbs smoothly with no heavy residue
• Layers well after toner and under moisturiser

Hero Ingredients

• 14-Layer Ultra-Low Molecular Hyaluronic Acid Complex: smaller molecules reaching deeper than standard HA
• Sea Water (Ulleung Island): first in the formula, delivering mineral-rich hydration
• Madecassoside + Beta-Glucan: calm and support barrier comfort
• Panthenol + Allantoin: soothe and soften
• Glyceryl Glucoside: supports the skin's own moisture retention

Who It’s For

Dehydrated skin that hasn't responded to standard hyaluronic acid products, wanting hydration with a bounce effect.

How to Use

1. Cleanse and tone: Prepare the skin with your usual toner.
2. Apply evenly: Dispense a small amount over the face and neck.
3. Pat to absorb: Press gently until the product settles.
4. Seal and protect: Follow with moisturiser and use sunscreen in the morning.

Pro Tips

• Layer from thin to thick: Apply after toner and before heavier creams as appropriate.
• Use a small amount: Add another light layer only where needed.
• Finish mornings with SPF: Sun protection supports tone, firmness and barrier health.
