A Korean hyaluronic acid serum from Isntree — 14 types of hyaluronic acid in a single lightweight formula, based on mineral-rich deep sea water sourced from Ulleung Island, Korea. Lila calls it an "elevated HA toner" and uses it to layer under other hydrating products at night. Erin switched from her previous serum and would repurchase. Fragrance-free. 50ml.

  • 14 Types of Hyaluronic Acid — Every Molecular Weight — most HA serums contain 1–3 HA forms. This serum contains 14 distinct hyaluronic acid derivatives including Sodium Hyaluronate, Hydrolyzed Hyaluronic Acid, Hyaluronic Acid, Potassium Hyaluronate, Sodium Acetylated Hyaluronate, Hydroxypropyltrimonium Hyaluronate, Sodium Hyaluronate Crosspolymer, Dimethylsilanol Hyaluronate, Hydrolyzed Calcium Hyaluronate, Sodium Sulfated Hyaluronate, Sodium Stearoyl Hyaluronate, Sodium Oleoyl Hyaluronate, and more — each delivering moisture at a different depth for truly comprehensive hydration.
  • Ulleung Island Sea Water — The Mineral-Rich Base — the serum's first ingredient is deep sea water from Ulleung Island (the same volcanic island source used by Round Lab in their 1025 Dokdo line). Rich in naturally-occurring minerals including calcium, magnesium, and potassium that support skin vitality and moisture balance.
  • Glyceryl Glucoside + Madecassoside + Beta-Glucan — Glyceryl Glucoside activates aquaporins (the skin's natural water channels) to help moisture flow more deeply into skin cells. Madecassoside (centella TECA active) repairs the barrier and calms inflammation. Beta-Glucan soothes and strengthens the moisture barrier.
  • Malachite Extract + Panthenol + Allantoin — Malachite is a copper-rich mineral extract with antioxidant and skin-energizing properties. Panthenol supports barrier lipid synthesis and moisture retention. Allantoin soothes and promotes cell renewal. Betaine adds plant-derived humectant depth.

After toning, apply a moderate amount to skin and gently pat for better absorption. Fragrance-free. 50ml.
