Innisfree Green Tea Seed Serum 그린티 씨드 세럼
The long-running hydrating serum built around green tea from the brand's own Jeju plantations, and one of the products most Korean consumers can picture without prompting. Green tea polyphenols have reasonable antioxidant credentials in the laboratory; in a serum like this the practical benefit is a light, non-greasy hydration layer with a clean green scent. It has been reformulated across several generations, each keeping the name and changing the texture.
What it is built around
Who it suits
Normal, combination and mildly dry skin wanting an everyday hydrating step that vanishes under makeup, and oily skin that dislikes heavier serums. It suits people who want something pleasant rather than something active. It will not do much for pigmentation, texture or lines — this is a hydration and comfort product wearing an antioxidant story.
How to use it
After toner, before moisturiser, morning and evening. Two or three drops on damp skin. It is light enough to layer under a richer cream in winter, and light enough to work alone in summer for oily skin. Follow the morning application with sunscreen, since antioxidants support sun protection rather than replace it.

What is the difference between essence and serum?
In Korean skincare, essence is typically a thinner, hydration-focused layer that preps skin, while serum is more concentrated with targeted actives like vitamin C or niacinamide. Essence usually comes first; serum follows. The line between them blurs, and not every routine needs both.
What is the difference between essence, serum and ampoule?
Essence is the lightest and most hydration-focused, serum is more concentrated and targeted, and ampoule is the most concentrated of the three. The boundaries are marketing convention, not regulated definitions.
