ISNTREE Ultra-Low Molecular Hyaluronic Acid Toner is a 300ml (10.14 fl.oz) Korean skincare toner formulated with hyaluronic acid of an ultra-low molecular weight. This smaller molecular size is designed to penetrate the skin's surface more effectively, delivering hydration to deeper layers while the toner itself absorbs quickly without leaving a sticky residue.

The toner provides deep hydration and contributes to a smoother skin texture. Its lightweight, watery consistency makes it suitable for layering under moisturizers or serums, and it can be used as part of a daily skincare routine for all skin types, including sensitive or acne-prone skin. The formula is vegan and fragrance-free, minimizing the risk of irritation from artificial scents.

Key aspects of this toner include its focus on moisture replenishment without heavy oils or comedogenic ingredients. It works to maintain the skin’s moisture barrier by delivering sustained hydration, which may help reduce the appearance of dryness or flakiness. The product is packaged in a generous 300ml bottle, offering practical value for regular use.

This toner is appropriate for individuals seeking a simple, effective hydration step in their regimen. It can be applied after cleansing by patting a small amount onto the face or by using a cotton pad. As it contains no essential oils or synthetic fragrances, it aligns with preferences for gentle, minimalist skincare. The ultra-low molecular hyaluronic acid component distinguishes this toner from standard hyaluronic acid formulations, as it is engineered to reach deeper skin layers for more efficient moisture delivery.
