COSRX Low pH Pore Deep Cleanser — 5.07 fl.oz Gentle AHA/BHA/PHA Face Wash for Blackheads & Sensitive Skin

COSRX Low pH Pore Deep Cleanser is a gentle, low-pH face wash that lifts blackheads and pore impurities while preserving your skin’s barrier.

This cushiony, soft-lathering cleanser combines AHA, BHA, and PHA with fermented red rice and inositol to refine texture and remove excess sebum without leaving skin tight or stripped. Designed for daily use or as a wash-off mask, the formula is non-comedogenic and hypoallergenic, making it suitable for those who want targeted pore care while maintaining a comfortable skin balance. Clinically tested performance data shows strong removal of makeup residue and sebum after a single application, so it works efficiently whether you’re removing daily grime or looking for deeper clarifying support.

How does this cleanser manage blackheads without over-drying sensitive skin?

The low pH keeps the cleanser close to skin’s natural acidity, helping active acids work effectively while protecting the barrier. A blend of chemical exfoliants (AHA, BHA, PHA) gently loosens trapped oils and dead skin, and fermented red rice plus inositol help smooth texture without abrasive grit.

• Low pH formula that limits barrier disruption
• BHA targets pore-clogging oil; AHA and PHA refine surface texture
• Fermented red rice and inositol for clearer-looking skin
• Non-comedogenic, hypoallergenic base suitable for sensitive types

Can I use this every day, and what are the recommended application methods?

Yes—use it as an everyday morning and evening cleanser with water for routine cleansing. For deeper pore care, apply to dry skin, massage briefly, and rinse as a wash-off mask to help dislodge stubborn blackheads and impurities.

• Daily: lather with water and rinse for balanced cleansing
• Deep cleanse: apply to dry skin, leave briefly, then rinse
• Works well as a first or second cleanse depending on makeup level
• Avoid leaving on as a prolonged treatment to reduce irritation risk

What results should I expect, and how quickly will I notice changes?

Many users notice improved removal of surface oil and makeup after the first use, with visible reduction in pore impurities reported after consistent use. Texture refinement and fewer visible blackheads typically appear over several weeks as the acids gradually clear buildup and support smoother skin renewal.

• Immediate: cleaner-feeling skin and less surface oil
• Short term: reduced makeup residue and improved pore clarity
• Ongoing: smoother texture and fewer clogged pores with regular use
• Results depend on skin type and concurrent skincare routine

Who is this for? This COSRX Low pH Pore Deep Cleanser is aimed at anyone seeking gentle yet effective pore care—people with oily or combination skin, those prone to blackheads, and individuals with sensitive skin who want exfoliating benefits without harsh abrasives. It’s a good match for users who prefer multi-use products (daily wash or wash-off mask) and for natural skincare fans interested in fermented ingredients like red rice. Avoid pairing with other strong exfoliants too frequently; if you have very reactive skin, introduce the product gradually and monitor tolerance.
