COSRX Low pH Pore Deep Cleanser — 5.07 fl oz Gentle AHA/BHA/PHA Face Wash with Fermented Red Rice for Sensitive Skin

COSRX Low pH Pore Deep Cleanser is a gentle, low-pH face wash formulated to lift pore impurities and reduce blackheads without overdrying sensitive skin.

This Korean-formulated cleanser combines a cushiony, stretchy texture with AHA, BHA and PHA actives plus fermented red rice and inositol to target clogged pores and rough texture while helping preserve the skin's comfortable barrier. The formula is non-comedogenic and hypoallergenic, so it can be used as a daily foaming wash or as a dry-skin wash-off mask for deeper pore care. Clinical testing shows notable removal of sebum and makeup residue after one use.

How quickly does this cleanser remove oil and makeup?

In a single application the formula is designed to dissolve excess sebum and lift surface impurities, making rinsing more effective. The low pH keeps the cleansing process efficient without stripping natural moisture.

• Clinically measured removal of sebum and makeup residue after one use
• Stretchy texture helps bind and lift pore impurities
• Rinses clean with minimal tightness when used correctly

Can sensitive skin tolerate the AHA/BHA/PHA blend?

The cleanser uses a low pH plus gentle concentrations of exfoliating acids paired with soothing ingredients to minimize irritation risk. It is formulated to be hypoallergenic and non-comedogenic, yet anyone with highly reactive skin should patch-test first.

• PHA and AHA for surface texture smoothing
• BHA to support pore decongestion without heavy irritation
• Fermented red rice and inositol help refine texture while supporting skin comfort

How should I use it for daily cleansing versus deeper pore care?

For everyday use, lather with water and massage gently to cleanse skin, then rinse. For targeted deep pore care, apply to dry skin, allow a short dwell time, then emulsify and rinse so the formula can lift blackheads more effectively.

• Daily: wet face, work into a light foam, rinse
• Deep cleanse: apply to dry skin as a mask for a short period, then add water to emulsify and rinse
• Use 1–2 times weekly as a deeper treatment depending on tolerance

What makes fermented red rice and inositol beneficial here?

Fermented red rice provides concentrated bioactive compounds compared with regular rice to help improve clarity and skin texture. Inositol and phytic acid complement the acid blend by supporting gentle renewal and contributing to a refined pore appearance.

• Fermented red rice: higher active content for clearer-looking texture
• Inositol: supports smoother-feeling skin surface
• Phytic acid: gentle adjunct to exfoliating acids for balanced action

Who is this for: COSRX Low pH Pore Deep Cleanser is created for those wanting targeted pore care—people with combination, oily, or congestion-prone skin who also need a gentle formula that won’t overly dry the skin. It suits users seeking a multitasking cleanser that can be swapped between everyday washing and a short, wash-off treatment to address blackheads and surface texture. If you have highly sensitive or compromised skin, perform a patch test or consult a skincare professional before introducing an acid-containing product into your routine.
