Most of Neogen's Real Fresh foams are antioxidant fruit washes that differ mainly in scent. The heartleaf version is the exception worth knowing about: it swaps the fruit for an actual soothing brief, which makes it the most purposeful, treatment-leaning member of the family — and a genuinely good pick for the skin it's aimed at.
The star is heartleaf — houttuynia cordata — which forms the water base and appears again as an extract. Houttuynia has become a K-beauty staple for calming redness and irritation, with a real, if still-developing, reputation behind it, and leading the formula it gives this foam a calming character the fruit versions simply don't have. It's backed by a legitimately soothing cast: guaiazulene (the blue, anti-inflammatory compound derived from chamomile), licorice-derived dipotassium glycyrrhizate, calendula, perilla and artemisia. For redness-prone, sensitive-leaning or blemish-prone skin, that's a well-chosen, purposeful combination rather than a marketing flourish.
Tea tree is the other defining ingredient, and it's a double-edged one worth being honest about. As both oil and leaf extract, it adds a mild antibacterial, blemish-targeting note that complements the heartleaf for acne-prone skin — genuinely useful. But tea tree is an essential oil and a recognized contact sensitizer, so while the rinse-off format keeps the risk low for most people, the most reactive or tea-tree-allergic skin should patch test, and it's the reason the foam isn't strictly fragrance-free (the light herbal scent is the tea tree). Soothing-and-sensitizing in one ingredient is the honest way to think about it.
The base differs subtly from the fruit foams too. It still uses gentle amino-acid (potassium cocoyl glycinate) and amphoteric (cocamidopropyl betaine) surfactants, but it's a touch more soap-forward (lauric and myristic acids feature), so it cleanses slightly more thoroughly with a clean rinse. For oily, congested skin that's the upside; for dry or barrier-compromised skin, it's a small reason to be mindful or follow with good hydration.
That sorts who it's for. Oily, combination, redness-prone and blemish-prone skin will get the most from it — it's calming and clarifying in a way the fruit versions aren't trying to be. Normal and even dry skin can use it with a hydrating follow-up. It's vegan (unlike the line's blueberry), alcohol- and silicone-free, but not fungal-acne safe (tea tree oil, lecithin, polyglyceryl caprate), and the most tea-tree-reactive skin should choose a fragrance-free centella cleanser instead.
In use, it's a creamy paste that lathers into a soft, fine foam, rinses clean, fresh and calmed, and carries a light herbal tea-tree scent. The generous 160g tube lasts months, and it slots naturally into a soothing or anti-blemish routine.
It's worth understanding why heartleaf has become such a fixture in K-beauty, because it's the reason this version is more than a gimmick. Houttuynia cordata earned its following on calming the redness and reactivity that plague sensitive and acne-prone skin, and pairing it with azulene, licorice and calendula — a coherent anti-inflammatory stack — gives the foam a genuinely soothing identity the fruit versions don't attempt. That makes it a smart fit within an anti-blemish routine specifically: a calming cleanse that won't antagonize skin you're already treating with actives. The practical way to use it is as the gentle constant around stronger steps — cleanse with it, then layer your leave-on treatments (a BHA, niacinamide, or a soothing serum) on calmed skin, rather than expecting the cleanser itself to clear breakouts. The tea tree is the one ingredient to keep an eye on: it's useful for blemishes but a recognized sensitizer, so while the rinse-off format keeps the risk low, anyone who has reacted to tea tree before should patch test, and the very dry or barrier-compromised should note the slightly more soap-forward base and follow with good hydration. Used that way, it's a purposeful, well-aimed cleanser — the rare 'flavor' in the line that's chosen for a function rather than a scent, and arguably the most useful of the Real Fresh foams for the skin it targets.
If you've struggled to find a cleanser that calms rather than aggravates blemish-prone, redness-prone skin, this is the one in the line built for exactly that — provided tea tree agrees with you. It's the rare 'fruit cleanser' range entry that actually earns a place in a treatment routine.
The bottom line: the one Real Fresh foam built around a genuine function rather than a fruit — heartleaf, tea tree, azulene and calendula make it a real soothing, anti-blemish cleanser, the most purposeful in the line. Buy it if your skin is oily, combination, redness-prone or blemish-prone, you want a calming yet thorough daily cleanse, and a light tea-tree scent doesn't bother you. Skip it if you're genuinely tea-tree-reactive or very dry (a fragrance-free centella cleanser is gentler), or if you're managing fungal acne. For sensitive, blemish-prone skin that tolerates tea tree, it's the standout of the family.
