This was my very first korean skincare products and I fell in love. This is serum, but Innisfree recommends use it as a first essence. So after you cleanse your face this should be the very first cosmetic you layer, then follow with toner and all the others. Its main ingredient is obviously green tea extract, and its a multitasking ingredient. It gives moisture, elasticity, protection and balance to the sebum production. Its one of the most powerful antioxidant so always worth to have it in your routine. Its has very light consistency and absorbs super quick. It plumps and moisturizes without any tackiness. It also helps to keep that moisture for many hours. This is my favourite serum in the summer time, its also great one if you like layering few skincare products in one routine. Its has a nice green tea scent, which for me is not overpowering at all. Any skin type should benefit from this one.
