ISNTREE Green Tea Fresh Serum is a lightweight skincare formulation designed to address concerns related to excessive sebum production and skin hydration imbalance. The serum contains Jeju green tea extract, a component known for its natural soothing and oil-regulating properties. This ingredient helps to manage shine and support a balanced oil-to-moisture ratio without stripping the skin’s natural barrier.

The product is intended for individuals with oily, combination, or normal skin types who seek a non-greasy, hydrating step in their routine. Its water-based texture absorbs quickly, making it suitable for use under moisturizers or sunscreen. The formula focuses on delivering hydration while minimizing the appearance of enlarged pores and excess oil throughout the day.

Key functional aspects include sebum control through green tea’s astringent qualities, alongside moisturizing agents that help maintain skin comfort. The serum is free from heavy oils or silicones, which contributes to its fresh finish. It can be applied in the morning or evening as part of a multi-step skincare regimen.

Packaged in a 50ml (1.69 fl oz) bottle, the serum is positioned as an affordable option within the Korean skincare segment. It does not rely on synthetic fragrances or dyes, aligning with a preference for gentle, plant-based ingredients. The product is manufactured by ISNTREE, a brand known for incorporating natural extracts from Jeju Island into its formulations. This serum is best suited for those looking to regulate sebum and maintain skin hydration without excessive layering or residue.
