COSRX Hyaluronic Acid Toner 100ml — Lightweight Daily Essence for Dry Skin, 4,000 ppm Hydration

This hydrating toner (Hydra Power Essence) combines a high concentration of sodium hyaluronate with sea buckthorn water to restore moisture balance and improve skin comfort day and night. Designed to layer easily under serums and creams, the formula absorbs quickly, making it suitable for both morning and evening routines. COSRX emphasizes clean formulations—this toner is free from parabens, sulfates, and phthalates and is cruelty-free and dermatologist-tested.

How does this toner add moisture without weighing skin down?

The product uses 4,000 ppm of hyaluronic acid (sodium hyaluronate), a humectant that attracts and holds water in the upper layers of the skin. Because it’s a lightweight essence, it penetrates quickly and pairs well with heavier moisturizers for a layered hydration approach.

• High 4,000 ppm sodium hyaluronate for effective water retention.
• Thin, fast-absorbing texture suitable for layering.
• Works under makeup and overnight without pilling.

Can people with sensitive or reactive skin use it?

COSRX formulates with skin-friendly ingredients and keeps irritants out of the recipe. The toner is hypoallergenic and dermatologist-tested, and it omits common sensitizers like parabens, sulfates, and phthalates, reducing the risk of irritation for many users.

• Hypoallergenic formulation reduces potential irritation.
• Free from parabens, sulfates, and phthalates.
• Dermatologist-tested and not tested on animals.

How should I use this toner in my skincare routine?

Use it right after cleansing, while skin is still slightly damp, to lock in moisture. Apply a few pumps across the face and gently pat to help absorption, then follow with your favorite serum and a moisturizer to seal hydration.

• Use 2–3 pumps after cleansing and toning steps if applicable.
• Gently pat in until absorbed; follow with cream for best results.
• Suitable for both AM and PM use; layer under SPF in the morning.

What ingredients stand out and what do they do?

The formula centers on sodium hyaluronate at a targeted concentration to support skin hydration. It also includes Hippophae rhamnoides (sea buckthorn) water, which contributes antioxidants and helps maintain skin comfort while you hydrate.

• Sodium hyaluronate (4,000 ppm) for focused moisture retention.
• Hippophae rhamnoides water for supportive antioxidant properties.
• Clean-beauty profile—no parabens, sulfates, or phthalates.

Who is this for: This toner is aimed at anyone with dry or dehydrated skin seeking a non-greasy daily hydrator, as well as people with normal or combination skin who want a lightweight essence to boost moisture. It’s also a good pick for sensitive skin types looking for a straightforward, clean formula to layer into a skincare routine.
