The Isntree green tea line, including the popular Fresh Toner and Fresh Emulsion, is renowned for its focus on minimal, yet effective, natural ingredients. The cornerstone of these products is the high percentage of Camellia Sinensis Leaf Extract, sourced specifically from the pristine environment of Jeju Island in South Korea. However, the efficacy of the product relies on more than just this star ingredient, leveraging a synergistic blend of other botanical extracts and functional ingredients to address the specific needs of oily and combination skin types.
Core Ingredients in Isntree Green Tea Products
Camellia Sinensis Leaf Extract
This is the star player in the Isntree green tea lineup. Harvested from Jeju Island, this high-quality extract is rich in polyphenols, amino acids, minerals, and proteins. Its active components, particularly catechins like EGCG, provide potent antioxidant benefits, protecting the skin from environmental stressors. Furthermore, its anti-inflammatory and sebum-regulating properties are crucial for soothing sensitive skin and controlling excess oil production.
Anti-Sebum P(HD)
Isntree's formula often includes a patented blend of plant extracts referred to as 'Anti-Sebum P(HD)'. This complex is designed to effectively manage sebum production, reduce pore size, and refine skin texture. It typically includes a mix of extracts such as Pinus Palustris Leaf Extract, Ulmus Davidiana Root Extract, Oenothera Biennis (Evening Primrose) Flower Extract, and Pueraria Lobata Root Extract.
Centella Asiatica Extract (Cica)
Commonly known as Cica or Gotu Kola, this extract is a powerful soothing and healing agent. It helps to calm irritated and inflamed skin, reinforce the skin's barrier, and even promote wound healing. Its inclusion makes the Isntree green tea line well-suited for acne-prone and sensitive skin.
White Willow Bark Extract (Salix Alba)
This ingredient is often included for its natural exfoliating properties. It contains salicin, a precursor to salicylic acid, which helps to gently exfoliate dead skin cells, unclog pores, and further assist in sebum control. Unlike harsh chemical exfoliants, this botanical source provides a milder, anti-inflammatory effect.
Soothing and Hydrating Agents
To complement the green tea, other ingredients are added to hydrate and soothe the skin:
- Allantoin: A renowned soothing ingredient that softens and protects the skin.
- Beta-Glucan: A humectant and soothing agent that intensely hydrates and repairs the skin barrier.
- Hydrolyzed Hyaluronic Acid: A low molecular weight form of hyaluronic acid that penetrates deeper into the skin for superior hydration.
- Dipotassium Glycyrrhizate: Derived from licorice root, it provides additional soothing and sebum-regulating benefits.

Deeper Dive into the Antioxidant Power
The antioxidant capacity of Isntree's green tea products is significant. Green tea is a powerhouse of polyphenols, which combat free radicals caused by environmental aggressors like UV rays and pollution. For example, the Isntree Green Tea Fresh Serum contains an impressive 77% green tea extract, providing a concentrated dose of these protective compounds. In addition to the main green tea extract, the serum is often formulated with specific catechins like Epigallocatechin Gallate (EGCG), a potent antioxidant that further boosts the formula's ability to soothe and protect the skin. Other antioxidant-rich botanicals like Ginkgo Biloba Leaf Extract and Blueberry Fruit Extract also contribute to the overall protective and revitalizing effect of the products.
Conclusion
Isntree's green tea skincare line is formulated with a simple, yet highly effective, philosophy that focuses on high concentrations of high-quality, natural ingredients. The cornerstone is the Jeju green tea extract, rich in antioxidants and amino acids, which provides the primary soothing and sebum-regulating benefits. This core is enhanced by supporting botanical extracts such as Centella Asiatica for its healing properties and white willow bark for gentle exfoliation. Hydrating ingredients like hyaluronic acid and beta-glucan ensure the formulas do not strip the skin of moisture. This well-rounded, minimalist approach makes the Isntree green tea range particularly appealing for those with oily, combination, and sensitive skin looking for effective and gentle skincare solutions.
