Key ingredients
01
Green Tea ExtractGreen Tea Extract
An extract from organic green tea leaves that Innisfree grows on Jeju. It is rich in polyphenol antioxidants such as catechins and EGCG, which help slow the skin aging driven by free radicals. The result is healthier-looking surface cells and less oxidative damage.
02
Green Tea Seed OilGreen Tea Seed Oil
An oil pressed from green tea seeds, and the ingredient that sets Innisfree apart. The linoleic and oleic acids strengthen the skin barrier and help it hold water. Its light feel means even oily skin can use it.
03
Hyaluronic AcidHyaluronic Acid
A standout hydrator that can bind up to 1,000 times its weight in water. It forms a moisture film on the surface that slows water loss.
04
Glycerin & BetaineGlycerin & Betaine
Humectants that draw water into the skin and help keep it there. They also leave the texture smoother and more even.

Yes. The light, water-based texture works year-round. There is a little oil in the formula, but the amount is small enough that even oily skin will not find it heavy.
Does green tea help with brightening?
Antioxidants like catechins help prevent pigmentation. The effect is more preventive than the targeted brightening you get from ingredients such as niacinamide or arbutin.
Is Jeju green tea different from regular green tea?
Innisfree says it uses organic green tea grown in the Jeju climate. The island's volcanic soil and clean environment are thought to affect the concentration of active compounds, though that difference is hard to put into numbers.
Do I have to follow the serum with a cream?
Dry skin will usually want a moisturizer on top. Oily or combination skin can often get by with the serum alone.
