The Beginner-Friendly COSRX Toner for Smoother, Clearer-Looking Skin
Curious about chemical exfoliation but nervous to jump in? This is the perfect first step. The COSRX AHA/BHA Clarifying Treatment Toner ($17.50) is a gentle, watery COSRX toner that sweeps away dullness and buildup, helping skin look smoother, softer, and more refined. No gritty scrubs, no drama, just a quick swipe that leaves your complexion looking fresh.
AHA vs. BHA: What's the Difference?
AHAs (like glycolic acid) work on the surface of your skin, helping lift away dull, dead skin cells for a smoother, brighter-looking finish. BHAs (like betaine salicylate) are oil-friendly, so they help keep pores looking clear and less congested. This toner combines both, making it a great all-rounder for texture and pores.
What's Inside the Bottle
- Willow Bark Water (10%): A botanical water that offers gentle exfoliation.
- Apple Fruit Water (10%): A naturally derived fruit water that supports soft, gentle exfoliation.
- Glycolic Acid (AHA): Helps exfoliate the skin's surface for a smoother, softer feel.
- Betaine Salicylate (BHA): A gentle form of BHA that helps pores look clearer and helps balance the look of oil.
- Allantoin and Panthenol: Comforting ingredients that help skin stay calm and hydrated.
How to Use It
- Cleanse your face.
- Soak a cotton pad with the toner.
- Gently wipe it over your face, avoiding your eyes and mouth.
- Follow with your essence and moisturizer.
- If you use it in the morning, finish with a broad-spectrum sunscreen rated SPF 30 or higher.
Exfoliation Tips for Happy Skin
- Don't double up: COSRX recommends avoiding use alongside other acids (AHAs/BHAs), retinol, and vitamin C in the same routine.
- Listen to your skin: If you feel dryness or stinging, use it less often.
- Sunscreen is non-negotiable: Exfoliated skin is more sensitive to the sun, so wear SPF every day.
- Skip it on mask nights: If you use a clay mask or exfoliating treatment, give your skin a break from this toner that day.
