Soothing ampoule · K-beauty · SKIN1004
Seven ingredients. One of them is Madagascar centella extract, and the other six exist to carry it. This is about as reductive as a face serum gets, and it sits behind nearly fifteen thousand ratings — a lot of confidence in a product that does almost nothing but calm.

01 Product information
Specifications as published on the listing, read in a US delivery context (New York 10001), so every figure is native USD.
What this product is
A 100 ml ampoule built on Centella Asiatica extract, with glycerin, butylene glycol and 1,2-hexanediol doing the solvency work and cellulose gum giving it body. There is no fragrance, no alcohol, no silicone and no preservative beyond the glycol pair, which is why it clears every claim on Skinsort's list.
How it is meant to be used
Two to three drops after toner, patted over redness-prone areas, then moisturiser. Because the formula is so short it stacks under almost anything, including retinoids and acids, and it is the usual recommendation for skin that is currently too irritated for a fuller serum.

Comedogenic and irritancy levels
Each ingredient is placed in one of four levels using the worse of its comedogenic and irritancy grades. Rows the source leaves ungraded are kept in their own bucket rather than being read as zero — an unrated ingredient is unknown, not innocent.
| Level | Ingredients | Share | What it means in practice |
|---|---|---|---|
| Level 1 · no flag | 2 | 28.6% | No comedogenic or irritancy grade recorded against it. |
| Level 2 · low (1) | 1 | 14.3% | Grade 1 — generally tolerated, occasionally relevant on very congested skin. |
| Unrated | 4 | 57.1% | No grade published. Unknown rather than safe; the honest reading is 'not assessed'. |

What the numbers say
The only series carrying observations is 3rd Party New, currently $18.00 against an all-time average of $22.80. At $18.00 the offer sits -18.2% against the $22.00 list price. The tracked range runs from $10.95 to $31.95 — a $21.00 spread that says more about third-party volatility than about the brand's own pricing. Monitoring began Aug 13, 2017, and the last tracked observation predates this capture by 1 day ago.
06 Who it suits
On the claim sheet this is the safest formula you can buy at this price, and it is among the cheapest per millilitre in the ampoule category. The trade-off is ambition: it hydrates and soothes, and does not meaningfully brighten, firm or resurface. Buy it as a calm-down layer, not as a treatment.
Buy it if
Reactive and sensitised skin, rosacea-adjacent redness, post-procedure recovery, teen and fungal-acne-prone skin, and anyone building a routine around a strong active.
Skip it if
Buyers who want visible anti-ageing or brightening from a single product, and anyone who finds centella unremarkable.

| Price, availability, seller | High | Buy box read in a US delivery context; USD native, no conversion |
| Rating and star split | High | Rendered on the listing at capture time |
| Review sentiment and aspects | Medium | Amazon's aggregate summary and aspect counts; individual review bodies were behind a sign-in wall and are not quoted |

| Comedogenic / irritancy screening | Medium | Only the graded subset informs it; unrated rows are reported as unknown |
| Price history | High on transcription, medium on recency | Summary table transcribed verbatim; the current column is a last observation |
Capture date 2026-10-31. Prices, rank and rating are live values and move between captures; two runs a day apart on the same listing routinely disagree.
