reviews we read ourselves
The Anua Heartleaf Serum is a gentle calming serum that uses heartleaf to soothe breakouts and redness. It's the serum step in Anua's heartleaf line, and people often use it as a set alongside the toner. Read through the 85 Olive Young reviews and calming dominates the conversation. Reviews saying trouble, breakouts and redness settled down are the most common at 20, followed by 15 calling it fast-absorbing and fresh. The official rating is ★4.7, with 73% marking it "gentle, no irritation." A lot of people say it's mild enough that even sensitive skin can use it without worry (13 reviews), and it's common to see it bought as the "heartleaf serum double + sunscreen" bundle (10) or noted as a repeat purchase (10). That said, it's a gentle calming serum, so don't expect a dramatic overnight change — and a small handful mentioned early breakouts, which we've left in as-is.

Sample Olive Young reviews decoded 85Serum/ampoule threads tally reference Total 85 Read on 2026-08-22

Calming is what comes up most in the reviews. Whether it's the heartleaf or not, posts saying trouble, breakouts and redness calmed down were the single largest group at 20 of the 85. The official skin-concern stats back it up too, with 54% choosing "great for calming." You can spot people reaching for it to calm skin when irritation flares, and acne-prone users who've settled it into a calming routine.

The texture absorbs fast and feels fresh. Fifteen reviews say it sinks in quickly and doesn't get sticky. Its gentleness (73% official, 13 in our read) means plenty of sensitive and reactive skin types feel safe using it, and 4 reviews describe layering it as the serum step after toner to help the next cream absorb. A few more (8) note it fills skin with hydration and moisture.

The buying pattern is bundles and repeat purchases. Ten people buy it as a planned set like the "heartleaf serum 30ml double + sunscreen," and 10 mention it's a repeat purchase. Five say they bought it for the heartleaf ingredient itself. As the serum in Anua's heartleaf line (toner, serum, ampoule), it's frequently paired with the toner. The flip side: it's a gentle calming serum, so if you're after a dramatic overnight change it's a different animal, and a small number mentioned early breakouts — so patch-test a little when your skin is reactive.

Counted by hand from the 85 reviews, only the ones with clear wording. If anything, these run low rather than inflated.

Strengths reviewers kept mentioning

  1. Heartleaf calming — trouble & redness careThe most common review of all (20). People say breakouts, acne and redness settle down. Backed by the official "great for calming" at 54%
  2. Fast-absorbing, fresh texture15 reviews say it sinks in quickly with no stickiness. Some layer it as the serum step to help the next cream absorb (4)
  3. Gentle enough for sensitive skin13 reviews call it gentle with no irritation (73% official). Lots of sensitive and reactive skin types say they use it without worry
  4. Trust that turns into sets & repeats10 bought the "serum double + sunscreen" set, plus 10 repeat purchases. Part of Anua's heartleaf line (toner, serum, ampoule) that people use together
04

Downsides (mentioned repeatedly)

  1. Not a dramatic changeIt's a gentle calming and hydration type, so it's realistic to judge it over a routine of days to weeks. This isn't an instant-fix serum that transforms skin in one go
  2. Rare early-breakout casesA small number mention trouble or irritation flaring early on. It varies by person, so we'd suggest patch-testing a little before use during reactive spells
  3. Official star distribution not capturedThis capture only includes the ★4.7, concern-type stats and the 81% badge. Once we get the star-distribution modal, we'll cross-check the numbers and add them

FAQ

Q. Does it actually calm trouble and breakouts?

Reviews saying trouble, breakouts and redness settled down were the most common at 20 of the 85, and the official skin-concern stats also show 54% choosing "great for calming." That said, this is a collection of user reviews, not a guarantee of medical efficacy, and it's realistic to use it consistently before judging the calming.

Q. Is it sticky?

Fifteen reviews say it absorbs fast and feels fresh. People also use it as the serum step to help the next cream absorb, and on dry days we'd suggest finishing with a cream afterward.

Q. Can sensitive, reactive skin use it?

13 reviews call it gentle (official "gentle, no irritation" 73%), so plenty of sensitive and reactive skin types say they use it without worry. That said, a small handful mention early breakouts, so during reactive spells, patch-test a little before use.

Q. What's the difference between the toner and the serum?

The heartleaf toner has a water-like texture for the swipe-toning and hydration step; the serum is a fast-absorbing calming-care step. Many people apply the serum after the toner and use them together.

Q. Is it better to buy as a set?

Ten reviews describe buying it as a planned set like the "heartleaf serum 30ml double + sunscreen." Generally people say buying at set or promo time is the better value.

Heartleaf (Houttuynia) is an ingredient often mentioned for calming care. Five reviews said they bought it for the ingredient, and Anua is well known for its heartleaf line (toner, serum, ampoule).

Q. Where does the data on this page come from?

The ★4.7, 45% combination skin, 54% calming, 73% gentle and 81% badge are Olive Young's official figures, while the keyword numbers are values we counted by hand across roughly 85 reviews (we only counted reviews with clear wording, so if anything they run low rather than inflated).

Q. How do I use Anua Heartleaf Serum?

After cleansing, apply it as the serum step after toner to let it absorb, then finish with cream — the common order across reviews On days when trouble or redness flares, many dab a little extra on the spot to use it for calming A planned set like the "heartleaf serum double + sunscreen" is the best value — buying at set time is how the repeat buyers do it Calming isn't instant; you have to use it steadily for days to weeks before you can judge
