anua Heartleaf 77% B3 Zinc Soothing Serum 30ml

Some formulas do their work quietly. This one starts with an aqueous extract of Houttuynia cordata — a plant long valued in Asian traditional medicine for its calming properties — which makes up 77% of the formula. Day after day, the serum does its job, and the skin gradually shows it: a smoother texture, a more even tone, without any single moment you can point to as the turning point.

Texture and actives — The bottle holds 30 ml of a lightweight fluid serum built around four verifiable key ingredients. Niacinamide at 5% helps even out skin tone and minimize the look of pores. Zinc PCA at 1% keeps sebum production in check. Panthenol (vitamin B5) supports the skin barrier as it repairs itself. Houttuynia cordata exosome extract, present at 1.5 ppb, adds to the calming action of the plant base. The texture stays light — mostly flower, leaf, and stem water from the plant — and absorbs without any sticky finish.

How to use it — Apply after cleansing and toning, wherever your skin needs it most — uneven tone, enlarged pores, early breakouts. A few drops are all it takes: press them onto the skin, spread gently with your fingertips, then pat lightly until fully absorbed. It works well as the last step of your evening routine, or as a targeted treatment at any point during the day. At 30 ml, the bottle typically lasts around one month with daily use, depending on how much of the face you cover.
