Korean Deep Hydration Serum with Ultra-Fine HA
This ultra-light hydrating serum from Isntree is formulated with ultra-low molecular Hyaluronic Acid, designed to penetrate deeply and replenish moisture where skin needs it most.
Unlike heavy or sticky hydrating serums, this formula delivers layered hydration without clogging pores, making it ideal even for oily and combination skin. The serum sinks in instantly, helping skin feel plump, refreshed, and comfortably hydrated throughout the day.
With added Panthenol and Beta-Glucan, it supports the skin barrier while calming dryness-induced sensitivity. Perfect as a daily hydration booster under creams, sunscreens, or makeup.
A minimalist, skin-friendly Korean formula suitable for teens and adults, and a reliable hydration step for every routine.
Why Ultra-Low Molecular Hyaluronic Acid Matters
Hyaluronic Acid works by binding water to the skin—but molecular size determines how deeply it can work. This serum combines multiple forms of Hyaluronic Acid, including ultra-low molecular weight HA, to help deliver hydration more efficiently across different skin layers.
This makes the serum especially suitable for:
-
Skin that feels tight even after moisturizing
-
Oily or combination skin lacking internal hydration
-
Climate-stressed or over-cleansed skin
-
Layered skincare routines that require fast absorption
The watery, weightless texture absorbs instantly, making it ideal for both minimalist routines and multi-step Korean skincare layering.
