Isntree

Ultra-Low Molecular Hyaluronic Acid Toner

For deeply hydrated, plump, dewy skin.

The hyaluronic acid toner K-beauty fans recommend by reflex — and one of the few in the category that genuinely earns the cult following. The headline is the 14 types of hyaluronic acid Isntree packs into the formula, ranging from ultra-low molecular weight (which penetrates deeper into the skin) through to high molecular weight (which sits on the surface to lock moisture in). Together, they hydrate at every layer of the skin, instead of just at one. The base is sea water from Korea's Ulleung Island, naturally rich in over 70 minerals that support skin hydration and reinforce the barrier.

The texture is a gel-like watery toner that absorbs in seconds without any stickiness — light enough to layer multiple times for the "7-skin method," substantial enough that one or two layers genuinely change how plump your skin looks. Panthenol, allantoin, betaine, and witch hazel keep the formula calming and gentle, and the generous 300ml size means you can use it freely without rationing — exactly the point for a daily hydrating step. Vegan, fungal-acne safe, fragrance-free, and free of essential oils.

Best For: Dehydrated, dry, or dull skin — also a great daily hydration step for all skin types (including oily and combination), and especially good for anyone wanting to try the "7-skin method" of layering toner for plumper skin.

Key Ingredients
14-Type Hyaluronic Acid Complex A fourteen-form hyaluronic acid blend ranging from ultra-low to high molecular weight. Hydrates the skin at every depth, from surface plumping to deeper absorption. Ulleungdo Deep Sea Water Mineral-rich sea water from Ulleung Island in Korea, naturally containing over 70 minerals (magnesium, calcium, zinc) that support hydration and barrier function. Panthenol and Allantoin A soothing duo that calms reactive skin and reinforces moisture retention. Betaine A natural amino-acid-derived humectant that strengthens cell membranes and reduces irritation. Witch Hazel and Hinoki (Japanese Cypress) Leaf Extract A calming-and-antioxidant pair that supports the skin barrier without astringency.
How to Use
After cleansing, dispense an appropriate amount onto your palms or a cotton pad. Pat gently onto the face and neck as the first hydrating step of your routine. Layer 2–7 times for extra plumping (the "7-skin method"). Follow with essence, serum, moisturizer, and SPF. Use morning and evening. Tip: For visibly plumper skin in the morning, layer 3–5 times at night before bed — apply a thin layer, pat in, wait 30 seconds, repeat. The ultra-low molecular weight HA needs that absorption time to do its work at deeper layers. This sounds extreme, but it's a classic Korean technique and the difference shows.
