How it works
This is the finishing step of a routine: an oil that closes it rather than a treatment that starts it. It sits as a film on the surface, so it is pressed on rather than rubbed in and stays noticeable for a while. It goes over the cream, because an oil down first blocks everything water based that would follow. Used at two or three drops it works; used generously it is mostly a way to oil a pillowcase. It is watery for an oil, which is why people who have given up on face oils under makeup often get on with this one.
Key benefits
- What it is: face oil, 50ml, used the final leave on step, over a cream.
- Texture: an oil that stays as a film on the surface.
- Aimed at: dry skin in winter, a dewier looking finish, wearing an oil in the morning.
- Original Korean Formula: the version sold on Korean shelves, not a US reformulation.
Key actives
Camellia Sinensis Leaf Extract
Camellia Sinensis Leaf Extract (green tea) is a polyphenol-rich botanical extract, one of the most common antioxidant ingredients across Korean formulas.
Sodium Hyaluronate
Sodium Hyaluronate is the salt form of hyaluronic acid, the form most Korean formulas use for its ability to bind water at more than one molecular weight.
Ceramide NP
Ceramide NP is one of the lipids that make up the skin barrier's own structure, included here to support that barrier alongside the rest of the formula.
Copper Tripeptide-1
Copper Tripeptide-1 is a peptide ingredient included in this formula's active build for its role supporting skin's own structural proteins.
Acetyl Hexapeptide-8
Acetyl Hexapeptide-8 is an expression-focused peptide used in Korean and Western firming formulas alike, and it is confirmed here on this row's own ingredient list rather than assumed from the product's name.
What is the KLAIRS Fundamental Watery Oil Drop 50ml?
It is a 50ml face oil with an unusually light texture, used as the last leave on step over a moisturiser. Being an oil it still forms a surface film, so nothing water based goes on after it. Two or three drops warmed in the palms covers a face.
Does the face oil go before or after my moisturiser?
After. An oil forms a film that nothing water based will get through, so anything applied on top of it mostly stays on top. That makes it the final leave on step of a routine. A sleeping mask on the driest nights can still go over it.
How many drops should I use?
Two or three for the whole face, warmed in the palms and pressed on rather than rubbed in. This is the step people overdose most often, and the result is a shiny finish and an oily pillowcase rather than better skin. On oily areas use less or skip them.
Can I use the 50ml in the morning?
You can, though an oil film stays perceptible for a while and can sit oddly under makeup. One drop pressed on and given several minutes is the way to try it. Most people find the evening the easier slot for an oil.
Is this the same version sold in Korea?
Yes, this is the Korean-market formula rather than a US reformulation of it. The 50ml comes with Korean primary labelling and an intact barcode, which is what lets you verify what you have received.

How to use
- Use it at the end of a routine, over any cream, so nothing has to pass through it.
- Two or three drops warmed in the palms is a whole face, pressed on with flat hands.
- Go heavier on dry areas and lighter across the nose and forehead if those get shiny.
- Avoid mixing it into the same palm as a water based serum, since the two do not layer and you get pilling instead.
Worth knowing
- Keep it clear of the eyelid margin, since an oil travels easily into the eye.
- Use two or three drops rather than a palmful, or most of it ends up on the pillow.
- On oily areas use it sparingly or skip them altogether.
