## How it works

Green Tea Serum is an ampoule serum from One Thing. One Thing is a Korean single-ingredient skincare brand: each toner and serum is built from one named plant extract, with no added fragrance or color. On this jar's own ingredient list, Camellia Sinensis Leaf Extract, Trehalose, Sodium Hyaluronate, Allantoin, Adenosine are named directly, which is what the key-actives panel on this page is built from rather than from the product name alone. Camellia Sinensis Leaf Extract is green tea extract, an antioxidant-rich polyphenol source, and it is why this ampoule serum is positioned the way it is. Use it after toner and before moisturizer, as the routine's concentrated treatment step, giving it a minute to settle before the next layer goes on. One Thing sells this as the Korean-market formula, the same one stocked on shelves in Korea rather than a version built for the US market.

## How to use

1. Apply after toner and before moisturizer. Pat or smooth it over a cleansed face and let it absorb before the next step, AM and PM.

## FAQ

### What is Green Tea Serum?

It is One Thing's ampoule serum (80ml). Its own ingredient list names Camellia Sinensis Leaf Extract, Trehalose, Sodium Hyaluronate, Allantoin, positioned the way the key-actives panel on this page describes, rather than actives assumed from the product name. It is used after toner and before moisturizer, as the routine's concentrated treatment step.

### How do I use Green Tea Serum?

Apply after toner and before moisturizer. Pat or smooth it over a cleansed face and let it absorb before the next step, AM and PM. Keep the same order every time you use it so you can tell what is actually working, and give a new step a few weeks before judging the result.

### Is Green Tea Serum the authentic Korean-market formula?

Yes. This listing is One Thing's Korean-market formula: the same ingredient list, barcode and batch code as the unit sold on shelves in Korea, rather than a version reformulated for US retail. That is the whole reason to buy a Korean-market brand from a specialist rather than a general retailer.

### Where does Green Tea Serum fit if I already use sunscreen or makeup?

Apply Green Tea Serum before sunscreen or makeup, and let it absorb fully first so it does not pill under the next layer. Sunscreen still goes on last in the morning, and makeup after that, regardless of how many treatment steps come before it.

### Who is Green Tea Serum suited for?

It suits normal, combination, dry or dehydrated and sensitive skin, and it is not restricted to any one skin tone or age group. As with any new step, patch-test on the inner arm first if you are new to this formula or to One Thing.
