COSRX Hydrium Watery Toner 280ml — Lightweight Hyaluronic Acid Hydrating Toner for Sensitive Skin

COSRX Hydrium Watery Toner is a lightweight, hydration-first Korean toner formulated with six types of hyaluronic acids plus allantoin and panthenol to boost moisture and soothe skin.

This clear, water-like toner refreshes and balances the complexion after cleansing without heavy residues. Designed to support sensitive skin, the formula focuses on replenishing moisture, calming irritation, and preparing skin for subsequent skincare steps. It’s free from parabens, sulfates, phthalates, and is not tested on animals, aligning with gentle, everyday use.

How does this toner hydrate without feeling sticky?

The Hydrium Watery Toner uses a blend of six molecular weights of hyaluronic acid to draw and lock in moisture at different skin layers. Its watery texture absorbs quickly, leaving skin feeling supple rather than tacky. Lightweight humectants attract hydration while panthenol and allantoin calm and reinforce the skin barrier.

• Six types of hyaluronic acid for multi-layer hydration
• Fast-absorbing watery consistency that layers well
• Panthenol and allantoin reduce redness and support barrier repair
• Non-comedogenic, suitable under serums and creams

Will this toner help sensitive or easily irritated skin?

The formula emphasizes gentle, skin-friendly ingredients and minimal irritants, making it a solid choice for reactive or sensitized skin. Allantoin and panthenol are included at calming concentrations to soothe inflammation and promote comfort. It’s also free from common harsh additives, which lowers the chance of irritation during regular use.

• Hypoallergenic and dermatologist-tested formulation
• Allantoin (0.1%) and panthenol (0.1%) to soothe and heal
• Free from parabens, sulfates, and phthalates

How do I add this toner to my daily routine?

Use it immediately after cleansing, morning and night, to restore moisture and prime skin for serums and moisturizers. Apply with palms or a cotton pad and gently press into skin for better absorption. Because of its lightweight profile, it layers cleanly under treatment products and sunscreen.

• Apply 2–3 pumps to clean skin; pat until absorbed
