Indigo Overnight Repair
Reviewed by SerumTruth Editorial · Price and formula checked July 2026
A premium calming and barrier-support night treatment built on Tatcha's proprietary botanical blend rather than disclosed percentages of familiar actives. It is priced like a luxury barrier cream because that is what it is: the appearance of a calmer complexion and a more comfortable-looking barrier by morning, not a high-dose treatment serum, and best justified if you specifically want its sensitive-skin-focused formula over a disclosed ceramide or centella alternative.

- Potency20 / 25
Dosed at studied levels, not fairy-dusted
- Heartleaf (Houttuynia Cordata): dosed at a studied level
- Hyaluronic Acid: dosed at a studied level
- Ceramides: present, but below a studied dose
How strongly the actives are dosed, led by the strongest, not how many there are.
- Delivery & stability14 / 20
Delivery tech + packaging that protects fragile actives
- Delivery: standard
- Packaging: open jar
- No fragile actives here, so packaging barely moves the score.
Delivery tech plus packaging, and packaging only counts when actives are fragile.

What’s inside
| Active | Disclosed | Dose |
|---|---|---|
| Heartleaf (Houttuynia Cordata) | n/a | Studied |
| Hyaluronic Acid | n/a | Studied |
| Ceramides | n/a | Light |
A serum-in-cream barrier treatment for sensitive, redness-prone skin, in Tatcha's signature indigo glass jar with a gold spatula. The real hero is Japanese indigo (Polygonum Tinctorium leaf and stem extract), positioned mid-list alongside mondo grass root (Ophiopogon Japonicus) and Salvia Miltiorrhiza root extract, ahead of sodium hyaluronate. Ceramide NG shows up lower in the deck as one supporting lipid among several, not a disclosed multi-ceramide blend. None of these actives are notably fragile, so the jar is a fair choice on preservation, though a jar still means finger or spatula access instead of a pump.
How it’s delivered
Air- and light-sensitive actives (vitamin C, copper peptides) lose potency fast in the wrong packaging, so delivery and the bottle are scored, not just what’s on the label.
The actives, explained
What the research says
In lab testing on skin cells, heartleaf extract raised levels of filaggrin, a protein tied to a smoother, better hydrated skin barrier.
Antioxidant Houttuynia cordata extract upregulates filaggrin expression in an aryl hydrocarbon-dependent manner. Fukuoka Igaku Zasshi, 2014. PubMed ↗
A multicenter study linked a topical hyaluronic acid serum with better looking hydration, tone, and texture over several follow up visits.

A study of the active, not this exact product. What matters for the score is whether this serum uses it at a comparable dose.
