Anua Heartleaf Quercetinol Pore Deep Cleansing Foam 5 oz

What it is

The Anua Heartleaf Quercetinol Pore Deep Cleansing Foam is a K-beauty face wash formulated to clear congested pores and calm reactive skin at the same time. In a single lathering step, it combines salicylic acid — a beta-hydroxy acid recognized for its ability to penetrate oil-filled pores — with heartleaf (Houttuynia cordata) extract and quercetinol, a quercetin-derived antioxidant with soothing properties. The 5 oz size makes it practical for daily use without running out quickly.

Who it's for

This cleanser is best matched to oily, combination, and acne-prone skin types that also experience background redness or post-breakout irritation — the oily-yet-sensitive profile that many K-beauty shoppers know well. If clogged pores, blackheads, or recurring congestion are your primary concerns, the salicylic acid here targets exactly that. People with very dry or currently compromised skin barriers should approach with caution: daily use of a BHA cleanser can tip into dryness or tightness if the barrier is already struggling. Anyone with a known aspirin sensitivity or salicylate allergy should skip this formula entirely.

How to use it

This foam works best as the second step in a double-cleanse routine — after an oil cleanser or cleansing balm has removed sunscreen and makeup — or as a standalone morning wash when the skin is relatively clean from the night before. Dispense a small amount, build a lather between your palms with water, then massage gently onto damp skin for 30–60 seconds before rinsing thoroughly. Starting with once-daily use is wise, especially if your skin leans sensitive; you can increase to twice daily once you confirm it's well tolerated. Because salicylic acid cleansers have a short contact time with skin, follow immediately with your toner or hydrating essence — never let freshly cleansed skin sit bare.

Key ingredients

• Salicylic acid: An oil-soluble BHA that penetrates into the pore lining to dissolve the sebum-and-dead-cell buildup responsible for blackheads and whiteheads. It also carries mild anti-inflammatory properties that support calmer skin over time.
• Heartleaf (Houttuynia cordata) extract: A cornerstone K-beauty botanical with well-documented calming and anti-redness activity. Its presence here is purposeful — it works to offset the potential for irritation from the BHA and suits the redness-prone skin types this product targets.
• Quercetinol: A stabilized derivative of quercetin, a plant flavonoid, included for its antioxidant and soothing effects. It helps address the environmental stressors that can drive redness and uneven tone in reactive skin.

Pros & cons

• Salicylic acid and calming botanicals work together, making it viable for the oily-but-sensitive skin type
• Generous 5 oz size holds up well with daily use
• Rated 4.6 out of 5 across nearly 19,500 reviews, indicating reliable satisfaction across a large user base
• Foam texture rinses cleanly without leaving a heavy or slippery residue
• Addresses three overlapping concerns — acne, visible pores, and redness — in a single cleansing step

• Rinse-off contact time limits how much work salicylic acid can do; leave-on BHA treatments will always outperform a cleanser for active pore treatment
• Can cause dryness or tightness in those with dry or sensitized skin, particularly when combined with other active ingredients like retinoids or strong exfoliants
• A foam alone may not cut through heavy SPF or full-coverage makeup — a separate first-cleanse step remains necessary in those cases
• Not an option for anyone with salicylate sensitivity

How it compares

For shoppers dealing with active blemishes alongside congestion, COSRX Acne Pimple Master Patch is a logical companion: the foam handles preventive pore care during cleansing while the hydrocolloid patch targets individual breakouts overnight, keeping the two roles cleanly separated. If redness and barrier repair are equally important after cleansing, COSRX Snail Mucin 92% Face Moisturizer pairs well as a follow-up — it's lightweight, non-comedogenic, and focused on recovery rather than additional actives, making it a good complement to an active-ingredient cleanser.

The verdict

The Anua Heartleaf Quercetinol Pore Deep Cleansing Foam earns its strong reputation by addressing a specific and common problem: skin that is simultaneously congested and sensitive. The salicylic acid gives the formula genuine pore-clearing capability, and the heartleaf and quercetinol bring enough calming action to make it tolerable for reactive skin types. Its breadth of positive reviews across a large audience suggests it performs consistently for the oily-to-combination, breakout-prone shopper it's designed for. Manage expectations on one point: this is a cleanser, not a leave-on treatment, so for persistent or severe acne, it works best as part of a broader routine that includes a dedicated BHA serum or spot treatment. As a daily wash, though, it's a well-considered, purposeful formula.
