Isntree

Isntree is a South Korean skincare brand founded in 2009. Its founders began by running a blog about cosmetic ingredients, one of the first of its kind in Korea, and started developing products in response to requests from the readers and customers who followed it.

The name combines 'Island', 'Natural' and 'Tree', reflecting the brand's nature-inspired, environmentally conscious approach. Isntree describes itself as the beginning of functional green beauty: skincare that pairs natural ingredients with clear, functional benefits and minimalist formulas.

The brand's best-known range is built around hyaluronic acid, from the Hyaluronic Acid Watery Sun Gel and Airy Sun Stick to the Aqua Gel Cream, Moist Cream and Ultra-Low Molecular Hyaluronic Acid Toner. It also makes ingredient-focused lines with Korean botanicals such as green tea, mugwort and yam root, including the Yam Root Vegan Milk Cleanser.

For shoppers, Isntree is a reliable choice for hydration and everyday sun care. Start with the watery sun gel every morning, layer the hyaluronic toner and a gel or moist cream depending on how oily or dry your skin feels, and keep the sun stick in your bag for top-ups. Because most of the range is built around one hero ingredient at a time, it is easy to mix Isntree with products you already love without overloading your skin.
