- Hippophae Rhamnoides Extract on the same panel, the formula's plant extract

- 50 ml to a unit
- Korean GS1 barcode matched against a Korea sourcing supplier's record for this item

## How it works

The panel on this serum names three forms of vitamin c rather than one: Ascorbyl Glucoside, Ascorbic Acid, 3-O-Ethyl Ascorbic Acid. Ascorbyl Glucoside is vitamin C bound to glucose, which keeps it stable until enzymes in skin release it. It is a mild, slow-release route to a vitamin C formula. On this panel it sits alongside Hippophae Rhamnoides Extract, Niacinamide and Melia Azadirachta Flower Extract. Sea buckthorn extract. The plant is unusually rich in vitamin C and carotenoids, and the extract is used as an antioxidant conditioning ingredient.

## How to use

1. Apply after the toner while the skin is still damp so a thin layer covers the face in one pass.
2. Press it over the whole area rather than dabbing it onto individual marks, since even tone needs even coverage.
3. Follow with a cream to hold it in place, and with sunscreen as the final morning step.
4. Do not skip the morning sunscreen, since mark work without that last layer is undone faster than it is built.

## FAQ

### Can I use this alongside other actives in my routine?

Yes. Glycerin is the lead active here, and it is formulated to sit alongside the rest of a routine rather than replace it. Introduce any new step on its own for the first week or two before adding it next to another strong active, so it is easy to tell which product is responsible for any change. Once it is settled into the routine, it layers the way any other serum in a Korean routine does.

### How do I know this is authentic and not a US-reformulated version?

Check the box against the listing: an authentic Korean-market SKU carries Korean-primary packaging and an intact Korean-market batch code, not a US-only relabel. Numbuzin's Korean-market formulas are sourced specifically to preserve that, rather than substituted for the US-shelf version some retailers carry under the same name.

### When in a routine should I use this serum?

Use it as the serum step, AM and PM, after toner and before moisturizer. Placing a serum out of order is the most common reason a Korean routine feels like it is not working, so keep this one at its own step rather than doubling it up with a product built for a different stage. Give it a few weeks at that placement before judging the result.

### What does Ascorbyl Glucoside do in this formula?

Ascorbyl Glucoside is vitamin C bound to glucose, which keeps it stable until enzymes in skin release it. It is a mild, slow-release route to a vitamin C formula. It is named on this product's own ingredient panel.

### What does Niacinamide do in this formula?

Niacinamide supports an even-looking skin tone and works alongside the formula's humectants to keep the surface comfortable. It is one of the most studied actives in Korean formulation for tone evenness and is gentle enough for daily AM and PM use. It sits at its own position on this product's own ingredient list rather than being assumed from the product name.
