What is in Heartleaf 77% Soothing Toner?
Anua’s Heartleaf 77 Soothing Toner leads with 77% heartleaf (Houttuynia cordata) and hyaluron for what the brand calls fresh, lightweight hydration and a balanced, dewy look. Brand pages list supporting botanicals such as centella and chamomile on the INCI alongside several hyaluronic acid derivatives. The desk reads it as a watery, soothing toner — not an exfoliating acid toner.
Any percentage claims about temperature drop, sebum or hydration boosts on marketing creatives are brand-reported. They are not Cast Index measurements. Omit them from headlines; keep the verified 77% heartleaf and use directions.

What should you know about season finish — couture glass skin?
Glass skin wants a calm, hydrated canvas. Show-week skin often arrives reactive from travel, heaters and continuous makeup. A heartleaf toner is the desk’s lightweight calm-and-slip step after CeraVe cleanse and before niacinamide or moisturiser — temperature of the finish stays “skin,” not irritated.
It supports the Paris couture read: luminosity without inflammation noise in the photograph.

What should you know about working kit?
After cleanse, pat or sweep toner across the face. Follow with serum, lotion and SPF by day. It pairs with The Ordinary Hyaluronic Acid or Niacinamide depending on the brief; avoid stacking with strong AHA toners in the same pass unless the wearer already tolerates that regimen.
Wrong as a substitute for moisturiser on dry skin. Wrong if the brief needs exfoliation — choose a dedicated AHA with its own sun-sensitivity warnings instead. Wrong as a treatment for clinical dermatitis.

What should you know about limitations and brand cautions?
Cosmetic soothing only. Discontinue if irritation occurs. Check the full INCI for personal allergens. Keep expectations tied to hydration and comfort of feel — not medical redness therapy.
