About this item

  • Gentle plant-based exfoliation: 10% willow bark water and 10% apple fruit water lift away dead skin cells without harsh scrubbing.
  • Clearer-looking pores: glycolic acid and betaine salicylate help smooth bumpy texture and clear clogged pores.
  • Soothed, not stripped: panthenol and allantoin calm skin while the acids work; free from drying alcohol.
  • Low pH that suits skin: pH-balanced at around 4.0, so it works with your skin's natural balance, not against it.
  • Preps your routine: sets skin to absorb serums and moisturisers better; fragrance-free and paraben-free.
  • Ease in gradually: start 3-4 times a week, building to twice daily as skin adjusts, with SPF every morning.

Description

COSRX AHA/BHA Clarifying Treatment Toner gently refreshes your skin with natural fruit acids. This clear, lightweight formula helps unclog pores and smooth rough patches without harsh scrubbing. Made with willow bark and apple fruit water, it balances your skin's natural pH while prepping it for the rest of your skincare routine. Perfect for most skin types, this toner works quietly to reveal clearer, brighter skin with each use. The alcohol-free, fragrance-free blend makes it a kind choice for even sensitive skin. Add this gentle step to your daily ritual and watch your skin thank you.

What Makes This Toner Special

This gentle toner helps your skin in many ways at once. The natural mix of AHA (from apple) and BHA (from willow bark) works to clear away dead skin cells that can make your face look dull. These plant-based acids help smooth bumpy texture and clean out pores without harsh scrubbing. The formula has no alcohol, no strong scents, and no harsh stuff that might upset your skin.

With each use, you'll notice your skin feels fresh, not tight or dry. The light, watery feel sinks in fast and helps your other skincare work better too. COSRX keeps things simple and kind to your skin with 85% natural parts in each bottle. The clear formula works well under makeup and won't leave any sticky feel behind.

How It Helps Your Skin

This toner works hard in the most gentle way. It helps with many skin needs at once:

  • Smooths rough, bumpy skin texture
  • Helps clear clogged pores
  • Balances oil without drying
  • Adds light moisture
  • Makes skin look brighter
  • Helps fade dark spots from old breakouts
  • Sets your skin's pH to the right level
  • Preps skin to soak up your next products better

The best part? It does all this without harsh scrubs or strong chemicals. Your skin gets the help it needs without the parts that might cause harm or upset. The low pH (around 4.0) means it works with your skin, not against it.

Kind-to-Skin Ingredients

What goes into this toner matters as much as what stays out. The star helpers are Willow Bark Water and Apple Fruit Water (10% each). These plant waters gently lift away dead skin cells. The formula also has panthenol and allantoin to calm and soothe as it works.

You won't find harsh stuff like:

  • No alcohol to dry your skin
  • No added scents that might cause redness
  • No parabens or sulfates
  • No phthalates

This means even if your skin gets upset easily, you can try this toner with more peace of mind. The clean, clear formula helps your skin without adding extra stress or irritation.

Simple Steps for Best Results

Using this toner is easy to fit into your daily skin care:

  • Wash your face with your normal cleanser
  • Put a small amount on a cotton pad or your palms
  • Gently wipe or pat across your face and neck (skip the eye area)
  • Let it soak in for a few seconds
  • Follow with your serum and moisturizer
  • Always use sun protection during the day

For skin that's new to acids, start slow – maybe 3-4 times a week. You can work up to twice daily as your skin gets used to it. A little goes a long way, so the 150ml bottle lasts about 5-6 months with daily use. Store it at room temp, away from bright light to keep it working its best.

Who This Toner Works Best For

The gentle formula makes this toner good for many skin types. It's best for:

  • Normal skin that needs a boost
  • Oily or mixed skin that needs balance
  • Skin with bumpy texture
  • Dull skin that needs brightening
  • Sensitive skin that can't handle strong products

If your skin is very dry, you might want to use this less often and make sure to use a good moisturizer after. This toner works well year-round but can be extra helpful in humid weather when skin tends to get oilier. The clear, light feel makes it perfect for layering under other skincare without feeling heavy.

Ready for skin that feels fresh, clean and happy? Add COSRX AHA/BHA Clarifying Treatment Toner to your daily routine and give your skin the gentle care it craves. Your path to clearer, smoother skin starts with one simple step. Shop now and feel the Calm Haven difference!

How to Use

Start with a clean face, applying the toner using a cotton pad or your palms. Swipe gently across the face and neck, avoiding the eye area. Use the toner in the morning and evening, followed by your preferred serum or moisturizer. Remember to apply SPF 30+ during the day. For those with sensitive skin, begin by using the toner 3–4 times weekly to assess tolerance. Store the product at room temperature (15–25°C), away from direct sunlight. The unopened bottle lasts for 24 months, and once opened, it should be used within 12 months. With regular use (2–3 pumps daily), a 150ml bottle typically lasts 5–6 months; weekly use can extend its longevity to 8–9 months. Suitable for adults aged 18–45, with benefits for teens under dermatological supervision and older users seeking gentle exfoliation to combat signs of aging. Incorporate into your routine after cleansing, avoiding combining with other strong acids or high-pH products to maximize effectiveness and minimize irritation.

Apple water · Willow bark · Alcohol-free

Exfoliation you can use every day.

Apple fruit water and willow bark water at 10% each, in an alcohol-free, fragrance-free toner — the mildest way into acids.

What does it do?

Gentle enough to be boring.

Most acid products are events. This one is a habit — which is usually what actually changes skin texture.

Smooths without scrubbing

Plant-derived AHA and BHA sources do the work, so there are no grains and no scrubbing.

Keeps pores in order

Willow bark water is the BHA side, aimed at congestion and the bumps that come with it.

Nothing sharp in the list

No alcohol, no added fragrance, no parabens or sulfates — and panthenol and allantoin for comfort.

What's in it?

Two plant waters, at 10% each.

Around 85% naturally-derived, at a low pH of about 4.0.

10%

Apple fruit water

The AHA side of the pairing, for surface smoothness.

When I skip it, my skin lets me know

I've gone through so many bottles of these and my skin throws a fit whenever I stop using it.

A gentle way in for acid beginners

I have been using this since for a few months now and i have to say that surprisingly it really does make pores less visible. it is a great toner to mix with other acids or for an acid beginner to get used to them or try them out.

Start here before you buy anything stronger.
