The "Surface-Polishing" Daily Prep
This is the high-performance "Pore-Clearing" specialist designed to physically "reset" your skin's texture every morning. The COSRX AHA/BHA Clarifying Treatment Toner isn't just a liquid—it’s a precision-engineered "Micro-Exfoliant" that uses a low-pH mineral water base to physically dissolve the "glue" holding dead skin cells together. By combining botanical acids with volcanic water, it physically "paves" the way for your serums to penetrate deeper, preventing the formation of whiteheads and "grainy" skin texture before they start.

Why it’s a Real Gem: It’s a "Texture-Refinement Filter." While many exfoliating toners are too aggressive for daily use, this formula uses a "Gentle-Acidity" philosophy. It features a weightless, watery texture that physically "mops up" the residual debris and hard-water minerals left after cleansing. It doesn't just clear; it actively "balances" your skin's pH, ensuring a high-definition, smooth finish that serves as the ultimate canvas for a flawless Glass-Skin routine.

Best For: Deleting "The Rough Patch." The ultimate choice for those with combination, oily, or "dull" skin who need a potent, non-stinging daily layer to physically "unclog" their pores and maintain a polished, clear complexion.
