Isntree Hyaluronic Acid Toner (Discontinued)
The Isntree Hyaluronic Acid Toner is a legendary hydrating step in K-beauty routines, specifically formulated to replenish moisture levels without the weight of heavy creams. This toner features Sodium Hyaluronate as its star ingredient, a salt form of hyaluronic acid that penetrates the skin to provide lasting plumpness and relief from dehydration. Complemented by Glycerin and Butylene Glycol, it effectively draws moisture into the skin barrier. The addition of Trehalose acts as a protective sugar that helps prevent moisture loss, making it an excellent choice for those dealing with transepidermal water loss. In terms of texture, the minimalist ingredient list indicates a lightweight, watery consistency that absorbs almost instantly without leaving a sticky residue. While this specific original formulation has been discontinued, its legacy remains as a gold standard for non-comedogenic hydration. It is entirely free from fragrance and essential oils, making it a soothing choice for reactive complexions or those following a fungal-acne safe regimen.
