Esntri Ultra-Low Molecular Hyaluronic Acid Serum 50ml

Hyaluronic Acid Serum with an ultra-low molecular weight formula from the Korean brand Isntree is a hydration-focused skincare essential in a generous 50ml size, made for daily use in a layered skincare routine. Isntree formulates this serum with 14 different types of hyaluronic acid across a range of molecular weights, including an ultra-low form measured at around 329 daltons, allowing it to reach deeper into the skin’s surface layers compared to standard single-weight hyaluronic acid products.

The serum has a lightweight, quick-absorbing texture that leaves no sticky residue on the skin. It is enriched with mineral-rich deep seawater sourced from Ulleung Island in Korea, along with soothing ingredients such as madecassoside, panthenol, and beta-glucan. Isntree manufactures its products in South Korea, follows vegan formulation principles, and does not test on animals, with a focus on fragrance-free formulas that avoid common irritants.
