Isntree Hyaluronic Acid Toner 400ml

A first-step hydration toner powered by 5 types of hyaluronic acid

This hyaluronic acid toner delivers an instant surge of moisture to skin that feels tight right after cleansing. Formulated with five molecular weights of hyaluronic acid—low, medium, and high—it builds layers of hydration from the deeper layers of skin all the way to the surface. The watery texture absorbs quickly without any sticky residue, and because it's oil-free, it leaves a lightweight, refreshing finish.

Clinically proven gentle with a 0.00 irritation index

In a skin irritation test conducted by P&K Skin Clinical Research Center, this toner scored 0.00 on the irritation index and was classified as non-irritating. Safe for daily use, even on sensitive skin. The generous 400ml size means you can use it liberally—whether you're wiping, patting, or soaking cotton pads for a hydrating mask.

A moisture-rich formula designed for normal to dry skin

Beyond hyaluronic acid, this toner is packed with skin-quenching ingredients that support long-lasting hydration.

• Althaea Rosea Root Extract: A patented ingredient (No. 10-0887294) that supports moisture retention
• Aloe Barbadensis Leaf Extract: Helps skin absorb moisture quickly and forms a protective hydration layer
• Portulaca Oleracea Extract: Soothes and calms the skin
• Panthenol and Beta-Glucan: Nourish and reinforce the skin's natural defenses

Ideal for anyone who craves dewy skin right after cleansing, or those who love the 7-skin method and want to layer moisture for a plump, hydrated complexion.

Your first hydration step right after cleansing

This is a toner designed to be used immediately after cleansing. Apply it right away before moisture evaporates from freshly washed skin to help boost the absorption of the essences, serums, and creams that follow. Formulated with five types of hyaluronic acid in a range of molecular weights, it delivers hydration to both the surface and deeper layers of the skin.

Suitable for morning and evening use

There's no time restriction—you can use it in both your morning and evening routines. In the morning, it works as a hydrating base before makeup. In the evening, it replenishes moisture in skin that's been stressed throughout the day. The lightweight, watery texture absorbs without any sticky residue, so it won't interfere with makeup application.

A multi-use toner you can customize

You can use it in several different ways depending on your preference.
- Wipe method: Saturate a cotton pad and gently sweep it across your skin following your skin's texture
- Pat method: Pour into your palms and lightly tap all over your face until absorbed
- Toner mask: Soak thin cotton pads generously and place them on dry areas for 3 to 5 minutes
- Layering method: Apply small amounts in multiple layers to build up hydration

The generous 400ml size means you can use it liberally without running out quickly.

Pairing it with your next steps by skin type

If you have normal to dry skin, follow this toner with a hyaluronic acid essence, then seal it all in with a hydrating cream for long-lasting moisture. For combination skin, use the layering method on dry cheek areas only, and keep the T-zone light with just one pass. If your skin overproduces oil due to dehydration, building a strong moisture foundation with this toner can help bring balance.

Storage and usage notes

Though it contains no oils, the high concentration of hyaluronic acid may feel slightly slippery on the skin. Applying too much at once and rubbing it in can cause a foam-like appearance—this is simply a characteristic of the ingredient, so apply in smaller amounts and you'll be fine. Store in a cool place away from direct sunlight, and use within 12 months of opening. If you experience redness, itching, or any irritation during use, discontinue and consult a dermatologist.
