Anua Heartleaf 77% Soothing Toner: What It Is, What's Inside, and Who It's For

Who This Is For

If your skin flushes easily, reacts to new products, or just feels tight and sensitive on a regular basis, the Anua Heartleaf 77% Soothing Toner was designed with you in mind. The formula is built for reactive skin, but because it is lightweight and fragrance-free, it works across all skin types — including oily and combination skin that still needs calming without extra weight.

If you are pregnant, breastfeeding, recovering from a procedure or using prescription skincare, check the brand's current guidance and ask your doctor before adding it. The brand describes it as vegan and cruelty-free, and it contains no added fragrance, which removes one of the most common sources of irritation in toners. If you have been reluctant to add a toner because of past reactions, this is a reasonable place to start.

What It Is and How It Feels

This is a water-textured toner, meaning it pours and spreads like water and leaves no sticky or tacky residue. It absorbs quickly, which makes it practical in both morning and evening routines when you do not want to wait long between steps.

The formula's defining feature, according to the brand, is that 77% of its base is not plain water but Houttuynia Cordata Flower/Leaf/Stem Water — the extract from the heartleaf plant. That concentration puts the active botanical at the front of the formula rather than as a minor addition. The remaining base is built around humectants that help the skin hold onto moisture through the day.

The Ingredients That Matter

Houttuynia Cordata Flower/Leaf/Stem Water makes up 77% of the formula, according to the brand. This heartleaf extract is the primary ingredient and the reason the toner is positioned for sensitive and reactive skin. It is formulated to calm redness and soothe irritation.

Panthenol is a form of provitamin B5 that supports the skin barrier and helps skin feel comfortable. It appears in the top ten ingredients here, meaning it is present at a meaningful level rather than a trace amount.

Centella Asiatica Extract is another calming botanical. It is a common presence in Korean skincare formulated for sensitive or stressed skin, and here it works alongside the heartleaf base.

Portulaca Oleracea Extract, from the purslane plant, adds another layer of soothing support to the formula.

The formula also includes Glycerin and Betaine, two humectants that draw moisture to the skin. The toner does not list a hyaluronic acid complex in the first twelve ingredients by name, but the brand describes a 7-type hyaluronic acid complex as part of the full formula, contributing to the hydration that follows calming.

How to Use It and Where It Goes in a Routine

Apply it immediately after cleansing, before any serum or moisturizer. This is your first active step once skin is clean, and using it on slightly damp skin can help the humectants work more effectively.

You can apply it two ways. A cotton pad works well if you want a light physical sweep across the face to remove any residual trace of cleanser. Fingertips work just as well — tap or press the toner gently into the skin rather than rubbing, and let it sit for a moment before moving to the next step. Because it absorbs fast, you will not need to wait long.

The toner works after whichever cleanser you already use, so there is no need to switch to a matching line.

Use it morning and evening as part of a daily routine. There is no guidance suggesting it should be limited to once-daily use.

One caution to note: keep it away from the eye area, and if it does make contact with your eyes, rinse with water. For first-time users with highly reactive skin, a patch test before applying to the full face is a sensible precaution.

Toners in the Korean Skincare Routine

In Korea, toner is understood differently than in much of the West. It is rarely the astringent, alcohol-heavy liquid associated with pore tightening. Instead, the Korean toner step — sometimes called "skin" in Korean (스킨) — functions as the first layer of hydration and preparation, meant to soften and prime skin so that everything applied afterward absorbs more effectively.

Heartleaf, or Houttuynia Cordata, has a long history of use in traditional East Asian herbalism, and in recent years it has become a recognizable ingredient in Korean skincare. You will find it across many product formats — toners, ampoules, moisturizers — particularly in lines formulated for sensitive or blemish-prone skin. Soothing toners that lead with botanical waters rather than plain water have become a common category on Korean shelves, reflecting a broader preference for functional hydration at the first step of a routine.
