isntree

Isntree is a Korean skincare brand founded with a simple idea: honest ingredients make the best skincare. Before launching a single product, the founders created Korea's first cosmetic ingredient blog, analysing formulations from a consumer's perspective. That transparency-first approach shaped everything that followed. Today, Isntree formulates without over 2,000 harmful ingredients and maintains its own exclusion list of 100 additional substances. The name combines "Island," "Natural," and "Tree," reflecting a commitment to nature-based, clean beauty that delivers real, visible results without the noise.

The Yam Root Vegan Milk Cleanser is a brilliant starting point, a gentle, creamy cleanser that removes impurities without stripping the skin's natural moisture barrier. The Ultra Low Molecular Hyaluronic Acid Serum is equally beloved, using multiple molecular weights of Hyaluronic Acid to deliver hydration at every layer of the skin for a plump, dewy finish that lasts. The Hyaluronic Acid Moisturising Cream seals everything in beautifully, delivering deep, lasting moisture in a lightweight formula that works for all skin types. Rounding things out, the Hyaluronic Acid Watery Sun Gel SPF50+ PA++++ has earned a serious global following as one of the most comfortable, non-greasy daily SPFs available, protecting and hydrating in one effortless step.

Yes, Isntree is one of the most reliable K-beauty brands for sensitive skin. Every formula is free from artificial fragrance, Parabens, and mineral oils, with the brand's own exclusion list covering over 2,100 potentially harmful ingredients in total. The clean, transparent approach to formulation means sensitive skin types can navigate the range with confidence, knowing exactly what is going into each product and why.

Isntree's sun care range is one of the most talked-about aspects of the brand, with several SPF products that have earned a devoted global following for their lightweight, skin-loving formulas that feel nothing like traditional sunscreens. The Hyaluronic Acid Watery Sun Gel SPF50+ PA++++ is the hero of the range, a cult favourite that protects and hydrates in one effortless, no-white-cast step. The Hyaluronic Acid Fresh Sun Serum SPF50+ PA++++ is equally beloved, delivering a serum-light texture that absorbs beautifully and sits comfortably under makeup. The Hyaluronic Acid Natural Sun Cream SPF50+ PA++++ is a brilliant option for those who prefer a more traditional cream format, while the Hyaluronic Acid Airy Sun Stick SPF50+ PA++++ is a convenient on-the-go option for reapplying throughout the day without any mess or fuss.

For anti-ageing, the GIM PDRN Hydro Bouncy Ampoule is a standout, using Salmon-derived PDRN alongside Peptides to support skin renewal and restore bounce and firmness, while the TW-Real Care Tone & Wrinkle Care Eye Cream targets fine lines and discolouration around the delicate eye area. For dullness, the Hyaluronic Acid Toner and Hyaluronic Acid Water Essence work together to flood the skin with hydration and restore a healthy, radiant glow. Those dealing with redness will find the Ultra-Low Molecular Hyaluronic Acid Zinc Aqua Cream a brilliant soothing moisturiser, with Zinc working to calm and rebalance reactive skin. For visible pores, the Mugwort Calming Clay Mask is a weekly essential, drawing out impurities and tightening pores while Mugwort soothes any irritation in the process.

Isntree is 100% cruelty-free and doesn't test any of its products on animals. They also offer a range of vegan-friendly products, each clearly labelled so you only use the products that are right for you.
