[Isntree] Ultra-Low Molecular Hyaluronic Acid Serum 50ml

1. Product Overview

A lightweight, intensive hydrating serum designed to replenish moisture, improve skin suppleness and restore a plumper, smoother-looking complexion.

Formulated with 14 forms of hyaluronic acid and mineral-rich seawater from Ulleung Island, this serum delivers multi-level hydration without a heavy or sticky finish.

Its fast-absorbing texture makes it suitable for daily use and easy layering beneath moisturiser.

2. Why We Chose It

We selected this serum for its comprehensive blend of 14 hyaluronic acid derivatives, supported by panthenol, beta-glucan and soothing ingredients.

The combination of different hyaluronic acid forms helps attract and retain moisture, making it particularly useful for skin experiencing dehydration, tightness or a loss of plumpness.

An excellent hydration-focused treatment for both simple and layered skincare routines.
