Anua Heartleaf Quercetinol Pore Deep Cleansing Foam Review: The K-Beauty Cleanser That Does It All

Anua Heartleaf Quercetinol Pore Deep Cleansing Foam 150ml — $14.95 CAD

A good foaming cleanser is one of the hardest products to get right in skincare. It needs to clean effectively without stripping the skin’s natural oils, it needs to lather satisfyingly without relying on harsh sulfate surfactants, and it ideally contributes something actively beneficial beyond just cleaning. The Anua Heartleaf Quercetinol Pore Deep Cleansing Foam manages all three — and it does it at one of the most accessible price points in K-beauty.

What Is Quercetinol?

Quercetinol is a flavonoid compound derived from the outer shell of heartleaf (Houttuynia cordata). It’s a more concentrated, purified form of the calming and antioxidant compounds found in the heartleaf plant. In powder form (as used here), it acts as a gentle mechanical micro-exfoliant during the cleansing process while also delivering anti-inflammatory and antioxidant benefits topically. It’s a relatively new ingredient in K-beauty formulations and Anua is among the first brands to incorporate it effectively into a cleanser.

What Is It?

This is Anua’s water-based second-cleanse cleanser — designed to be used after an oil cleanser in a double-cleanse routine, or as a standalone cleanser on makeup-free days. It combines the brand’s signature heartleaf calming with quercetinol’s exfoliating benefits and BHA’s pore-penetrating action in a formula that produces a genuinely luxurious, dense foam without relying on skin-stripping surfactants.

Key Ingredients

• Heartleaf Extract (Houttuynia Cordata): Anti-inflammatory, antibacterial. Actively soothes during the cleanse process, reducing post-cleanse redness and irritation.
• Quercetinol: Concentrated heartleaf flavonoid in powder form. Provides gentle physical micro-exfoliation alongside antioxidant and anti-inflammatory benefits.
• BHA (Betaine Salicylate) 0.5%: Oil-soluble beta hydroxy acid that penetrates into the pore lining during the massage to loosen sebaceous plugs, blackheads, and congestion. Gentler than traditional salicylic acid at equivalent concentrations.
• Panthenol (Vitamin B5): Hydrates and soothes skin during the cleansing process, preventing post-cleanse tightness.
• Allantoin: Skin-conditioning agent that promotes cellular renewal and softens rough texture with consistent use.
• Amino Acid Surfactants: The cleansing agents are amino acid-based rather than sulfate-based, which is why the foam is rich and luxurious without stripping.

Foam Quality & How It Feels

The foam is genuinely outstanding — one of the densest, most cushiony foaming textures in K-beauty at this price point. A pea-sized amount (a genuinely small amount) generates enough foam to cover the full face. The foam is creamy-dense, not airy-thin, and glides over the skin without the friction or tugging that can worsen active breakouts. Post-rinse, the skin feels clean but not stripped — that “squeaky clean” sensation that signals a damaged skin barrier is completely absent. Skin feels balanced, slightly softened, and ready for toner.

Who Benefits Most

This cleanser shines for:

• Oily and combination skin: The BHA component makes it genuinely effective at reducing blackheads and congestion with regular use.
• Acne-prone skin: The combination of antibacterial heartleaf and BHA creates an environment that actively discourages breakout formation during cleansing.
• Anyone who has experienced barrier damage from harsh cleansers: The amino acid surfactant base is one of the gentlest available while still cleaning thoroughly.

Those with very dry skin should limit use to once daily (evenings only) or alternate with a milder, non-BHA cleanser.

Results Over Time

Week 1: Immediately cleaner-feeling skin with no post-cleanse tightness. Existing active blemishes respond less aggressively than with harsher cleansers.
Week 2: Noticeable reduction in blackheads and congested pores, particularly on the nose and chin. Skin texture begins to smooth out.
Week 4: Pore appearance is visibly improved with consistent daily use. Overall skin clarity increases. The quercetinol’s exfoliating effect contributes to a brighter, more even skin surface.

Pair It With

For the most effective double-cleanse routine, pair this foam cleanser (Step 2) with the Anua Heartleaf Pore Control Cleansing Oil (Step 1). The oil removes sunscreen and makeup; the foam cleanses and actively treats the pores. Follow with the Anua Heartleaf 77% Soothing Toner to restore the skin’s pH and calm any post-cleanse sensitization.

Comparison to Similar Products

• vs. CeraVe Foaming Facial Cleanser: CeraVe is a pharmacy staple with a good reputation, but it contains sodium laureth sulfate as the primary surfactant — effective but less gentle than amino acid-based formulas. The Anua is gentler and more actively beneficial.
• vs. COSRX Low-pH Good Morning Gel Cleanser: Both are low-pH, gentle, and suitable for sensitive/acne-prone skin. The COSRX is a gel type without BHA; the Anua foam adds BHA for enhanced pore management.
• vs. La Roche-Posay Effaclar Purifying Foaming Gel: Comparable pore-focused intent. The Anua adds the heartleaf soothing factor and is significantly more affordable.

Pros & Cons

✅ Pros: Dense, luxurious foam from amino acid surfactants • BHA for active pore management • Heartleaf for post-cleanse calming • No post-cleanse tightness • Very affordable at $14.95 • 150ml lasts 2–3 months • Fragrance-free

❌ Cons: BHA not suitable for daily use on very dry or severely sensitized skin • Not ideal as a standalone one-step cleanser when wearing SPF/makeup

Value for Money

At $14.95 CAD for 150ml, this is one of the most cost-effective, functionally advanced cleansers available in Canada. A tube typically lasts 2–3 months with daily use. The price-to-performance ratio is exceptional.

The Verdict

The Anua Heartleaf Quercetinol Pore Deep Cleansing Foam is what every foaming cleanser should aspire to be: dense foam, deep cleansing, active pore management, genuine soothing, and zero barrier disruption — all at an extraordinary price point. If you’ve been settling for a basic foam cleanser, this is the upgrade that will make you wonder why you waited.
