Heartleaf Quercetinol Pore Deep Cleansing Foam

Quercetinol is not a real ingredient. It's a branded name Anua invented to describe their combination of Houttuynia cordata extract with isolated quercetin — the same flavonoid that occurs naturally in heartleaf but now concentrated and listed separately on the INCI. Whether you consider this meaningful innovation or marketing sleight-of-hand depends on your tolerance for K-beauty brand storytelling. What matters more is whether the cleanser works, and on that front, the answer is a qualified yes that depends heavily on your skin type.

This is Anua's most active cleanser — a daily foam wash with 0.5% salicylic acid, capryloyl salicylic acid (LHA), and the Anti-Sebum P botanical complex, built on a 33.4% heartleaf extract base. It's designed for the subset of Anua's audience that needs more than soothing — the oily, acne-prone, blackhead-battling skin types who want their cleanser to actually do something about pore congestion rather than just wash off the day.

The surfactant system is where the gentle promise lives or dies, and Anua chose well. Sodium cocoyl glycinate and sodium lauroyl glutamate are amino acid-based surfactants — the gold standard for gentle foaming cleansers. They produce a dense, satisfying foam without the lipid-stripping aggression of sodium lauryl sulfate. The foam itself is genuinely pleasant — thick, cushion-like, and fine-bubbled in a way that feels premium during the brief lathering step. You need very little product to generate a full face's worth of foam, which makes the 150 mL tube last longer than expected.

The dual-BHA approach is the formula's most interesting technical feature. Regular salicylic acid at 0.5% provides direct, oil-soluble exfoliation within the pore lining during the cleansing step. Capryloyl salicylic acid, a lipophilic derivative developed by L'Oréal under the name LHA, penetrates more gradually and provides a slower, sustained exfoliating effect. Together, they create a two-speed pore-clearing system — immediate action from the salicylic acid and extended-release activity from the LHA. In a wash-off format with 30-60 seconds of contact time, this dual approach compensates for the brief exposure by maximizing the exfoliant diversity that reaches the pore.

The seven-type hyaluronic acid complex is an unusual commitment for a cleanser. Standard sodium hyaluronate shares space with hydrolyzed forms, crosspolymer forms, hydroxypropyltrimonium hyaluronate (which binds to skin even after rinsing), acetylated sodium hyaluronate, and potassium hyaluronate. The goal is straightforward: prevent the BHA and surfactants from leaving the skin dehydrated. In practice, the cleanser delivers on this — skin after rinsing feels clean and slightly matte but not tight or stripped, which is a genuine achievement for a BHA foam cleanser.

Performance on pores is real but requires patience. The first use gives you cleaner-feeling skin and a satisfying matte finish. After two to three weeks of consistent evening use, blackheads in the nose and chin area start looking visibly reduced. By six weeks, the overall pore texture is genuinely smoother. The changes aren't dramatic enough for before-and-after documentation, but they're consistent and noticeable when you compare your skin to where it was before you started.

The fragrance issue returns here, just as it did with the clay mask. This cleanser contains added fragrance — a light herbal-floral scent that's present during lathering and dissipates after rinsing. For a wash-off product with brief skin contact, the fragrance concern is less acute than in a leave-on formula, but it still represents a philosophical inconsistency for a brand that built its audience on fragrance-free formulations. Sensitive skin types who chose Anua specifically for clean-ingredient trust will notice this departure.

The salicylic acid also means this cleanser is not pregnancy-safe — a practical limitation that eliminates a significant portion of potential users during a period when skin often becomes more sensitive and reactive.

The heartleaf and quercetin base provides the anti-inflammatory foundation that makes the BHA tolerable for skin that would normally react to exfoliating cleansers. The quercetin, specifically, is a potent antioxidant with documented NF-kB inhibition activity. Whether the Quercetinol branding adds value beyond what the heartleaf extract already provides is debatable — quercetin is present in the extract itself — but the isolated addition ensures a standardized, higher concentration of the specific compound that drives the anti-inflammatory and antioxidant effects.

At $20 for 150 mL, the pricing is fair for a cleanser with this many active components. A pea-sized amount per use means the tube lasts three to four months of nightly use, making the per-wash cost negligible. For oily and combination skin types looking for a daily BHA cleanser that doesn't strip the barrier, this is a well-engineered option that delivers measurable results through genuine formulation sophistication rather than marketing alone.

For those already embedded in the Anua heartleaf ecosystem, this cleanser represents the most active member of the family — the one that shows up with tools rather than just soothing words. The heartleaf extract and quercetin provide the brand's signature calming, but the dual-BHA system and Anti-Sebum P complex give this product a mission that the toner and lotion don't share. It's not trying to calm for the sake of calm — it's trying to clean and clear while keeping the inflammatory fallout to a minimum.

The Anti-Sebum P complex — a proprietary blend of pine leaf, evening primrose, elm root, and kudzu root extracts — addresses sebum from a botanical angle, complementing the BHA's chemical pore-clearing with plant-derived oil regulation. Whether this complex delivers measurable sebum reduction beyond what the BHA alone achieves is hard to isolate, but the inclusion signals Anua's commitment to attacking pore congestion from multiple angles within a single product.

One practical note: this cleanser works best as the second step in a double-cleanse routine, not as a standalone. The foam surfactants are gentle, but they're not designed to dissolve heavy sunscreen or makeup on their own. Pair it with Anua's own cleansing oil or micellar water for the first step, and let the foam cleanser focus on what it does best — gentle exfoliation and deep pore work on skin that's already been surface-cleaned.

Formula

The Science

Salicylic acid's efficacy as a pore-clearing agent is well-established in dermatological literature. As a lipophilic beta-hydroxy acid, it penetrates the oil-filled environment of pores more effectively than water-soluble AHAs, dissolving the sebum and keratin that form comedones. At 0.5% in a wash-off format, the concentration provides gentle daily exfoliation that accumulates over time.

Capryloyl salicylic acid (LHA), developed as a next-generation salicylic acid derivative, offers enhanced lipophilicity and a more gradual, sustained release of salicylic acid activity. Published research demonstrates that LHA matches the efficacy of standard salicylic acid at equivalent concentrations while producing less irritation, making it particularly suitable for formulations targeting sensitive-but-oily skin.

Quercetin, the isolated flavonoid from Houttuynia cordata, has been extensively studied as an antioxidant and anti-inflammatory agent. Research confirms its ability to inhibit the NF-kB signaling pathway and suppress COX-2 activity. The 2022 comprehensive review of Houttuynia cordata's pharmacological effects documented quercetin as one of the plant's primary active compounds responsible for its anti-inflammatory and antioxidant properties.

Amino acid-based surfactants like sodium cocoyl glycinate demonstrate significantly lower skin barrier disruption compared to sulfate-based alternatives. Studies measuring transepidermal water loss after cleansing consistently show that amino acid surfactants preserve the skin's natural lipid barrier while still providing effective cleansing.

Dermatologist Perspective

Dermatologists commonly recommend low-concentration BHA cleansers for patients with oily, acne-prone skin who need gentle daily exfoliation without the irritation of leave-on BHA treatments. Board-certified dermatologists note that the amino acid surfactant base is a smart choice that minimizes barrier disruption during cleansing. The dual-BHA approach with LHA is recognized in dermatological practice as providing gentler, more sustained exfoliation. Dermatologists would advise patients to limit use to once daily (preferably PM) and to follow with a hydrating routine, as even gentle BHA cleansers can contribute to dryness with twice-daily use. The presence of salicylic acid means this cleanser should be avoided during pregnancy.

Guidance

Anua developed this cleanser as the pore-focused counterpart to their soothing-focused products, recognizing that their oily-skin audience needed an active cleanser that still aligned with the brand's gentle philosophy. The Quercetinol technology — heartleaf plus isolated quercetin — represents Anua's attempt to evolve beyond raw botanical extraction into targeted active delivery.

Myth vs. Reality

Myth

BHA in a cleanser doesn't work because it rinses off too quickly.

Reality

While the contact time is brief compared to leave-on BHA treatments, research shows that BHA in cleansers at appropriate concentrations still provides meaningful pore-clearing activity. The oil-soluble nature of salicylic acid allows it to penetrate pore linings within the 30-60 second lather time, and the effect accumulates with daily use.

Myth

Foam cleansers are always stripping and bad for your skin.

Reality

The stripping effect depends on the surfactant, not the foam. This cleanser uses amino acid-based surfactants (sodium cocoyl glycinate and sodium lauroyl glutamate) that are significantly gentler than sulfate-based foaming agents while still producing a satisfying lather.
