COSRX Low pH Niacinamide Micellar Cleansing Water 100ml — gentle, oil-controlling, fragrance-free cleanser

COSRX Low pH Niacinamide Micellar Cleansing Water is a gentle, pH-balanced micellar formula that removes makeup and impurities while calming sensitive, oily, and acne-prone skin.

This lightweight cleansing water combines niacinamide and zinc PCA with skin-soothing actives to cleanse without stripping natural moisture. Designed to work at a skin-friendly low pH, the formula lifts dirt, excess sebum, and light makeup from the face using micelle technology, leaving skin refreshed and primed for the rest of your routine. It is fragrance-free and free of harsh chemicals, making it suitable for daily use and for skin that reacts to stronger surfactants.

How does this micellar water remove makeup without drying my skin?

The micelles in this cleansing water act like tiny magnets to attract and dissolve oil-based impurities while the low pH preserves the skin’s natural barrier. Niacinamide helps maintain hydration and promotes an even-looking complexion, while soothing extracts counteract any irritation from removal. You’ll get efficient cleansing with minimal rubbing, which reduces friction and sensitivity.

• Micelle particles for gentle oil and debris removal
• Low pH to protect barrier and hydration
• Niacinamide supports skin tone and moisture retention
• Soothing madecassoside and allantoin to calm redness

Can this help control oil and prevent clogged pores?

Formulated with zinc PCA alongside niacinamide, the cleansing water helps manage excess sebum at the surface where oil and impurities mix to form clogged pores. Regular, gentle removal of oil and residue reduces the likelihood of buildup without stripping necessary oils. It’s not a treatment to cure acne, but it supports a cleaner canvas which can improve the performance of other targeted products.

• Zinc PCA assists in sebum regulation and surface oil control
• Daily use prevents build-up that can trap debris
• Non-irritating formula avoids rebound oiliness from over-drying

Is this safe for sensitive or reactive skin types?

This cleansing water was developed to be non-irritating and is fragrance-free, using calming ingredients like madecassoside and allantoin to soothe and reduce visible sensitivity. Because it avoids harsh surfactants and maintains a skin-appropriate pH, it minimizes disruption to the skin’s barrier. Still, patch testing new products is recommended for highly reactive skin to ensure individual compatibility.

• Fragrance-free and free from common harsh chemicals
• Contains madecassoside and allantoin for immediate soothing
• Clinically tested for non-irritation at the intended use level

How should I use this cleansing water in my daily routine?

Apply the micellar water to a cotton pad and gently sweep over areas with makeup, sunscreen, or excess oil until the pad shows no residue. There’s no need to rinse after if you’re using it as a quick refresh, but follow with a gentle face wash if you prefer a double cleanse, especially in the evening. Use morning or night as needed to keep the skin clean without over-drying.

• Soak a cotton pad, wipe gently—do not rub harshly
• Repeat with fresh pads until the skin is clear of residue
• Optional: follow with a water-based cleanser for a double cleanse
