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

COSRX Low pH Pore Deep Cleanser is a gentle, low-pH face wash that lifts blackheads and pore grime using mild AHA, BHA, PHA acids plus fermented red rice without overdrying sensitive skin.

This cleanser combines a balancing low pH with gentle chemical exfoliants and fermented botanicals to clarify pores while protecting the skin’s moisture barrier. Its cushiony texture helps dissolve makeup residue and excess sebum, and can be used as an everyday foaming wash or applied to dry skin for a deeper, wash-off pore treatment. The formula is non-comedogenic and hypoallergenic, designed for people who want visible improvement in texture and congestion without aggressive stripping.

How does this cleanser actually reduce blackheads and clogged pores?

The formula blends low-pH surfactants with AHA, BHA, and PHA to loosen dead skin cells and dissolve sebum lodged in pores. Fermented red rice and inositol support skin clarity while phytic acid helps refine texture. Because the pH is close to skin’s natural level, the product clears buildup efficiently without harsh irritation.

• Mild BHA helps penetrate and dissolve oil in pores.
• AHA/PHA gently exfoliate surface dead cells for smoother texture.
• Fermented red rice and phytic acid promote clearer-looking skin tone.
• Low pH preserves the skin barrier while removing residue and makeup.

Can I use it every day, and is it safe for sensitive skin?

Yes — it’s formulated to be gentle enough for daily use because the low pH and balanced exfoliants minimize irritation compared with stronger acid treatments. The cleanser is non-comedogenic and hypoallergenic, making it suitable for many sensitive skin types, though patch testing is recommended if you react easily to new products.

• Daily rinsing mode: lather with water for regular cleansing.
• Targeted mode: apply to dry skin and leave briefly as a wash-off mask for deeper pore care.
• Non-comedogenic formulation reduces risk of new breakouts.
• Hypoallergenic claims lower likelihood of irritation for sensitive users.

What results and benefits can I expect after using this cleanser?

After one use, many users notice reduced surface oil and cleaner pores; with continued use the skin generally appears smoother and blackheads look less prominent. The combination of ingredients removes makeup residue and sebum while helping to prevent future congestion, and the low-pH texture keeps skin from feeling tight or stripped.

• Removes makeup residue and excess sebum effectively.
• Helps minimize the appearance of blackheads and pore congestion.
• Improves skin texture with regular gentle exfoliation.
• Leaves skin comfortable and balanced, not stripped.

How should I incorporate this into my existing skincare routine?

Use it as your first-step cleanser in the morning and evening to remove oil, pollution, and makeup. If treating stubborn congestion, apply on dry skin as a brief mask before rinsing, then continue with toner, serums, and moisturizer. Always follow with sunscreen in the morning when using exfoliating acids.

• Mornings: use with water, rinse, then apply sunscreen.
• Evenings: double-cleanse if wearing heavy makeup, or use as single-step if light makeup.
• Weekly: optional dry-skin mask application for deeper pore care.
• Pair with hydrating serums and barrier-supportive moisturizers.

Who is this for: COSRX Low pH Pore Deep Cleanser is aimed at people who regularly struggle with blackheads, visible pore congestion, or dull texture but want a gentle, non-stripping approach. It suits combination to oily skin and many sensitive skin types looking for effective pore care without harsh physical scrubs or high-pH detergents. If you use active acids in your routine, consider spacing applications to avoid over-exfoliation and always patch test when introducing a new acid-containing product.
