The Isntree Story
Isntree traces its roots to 2008, when founder Kim Jinwoo launched Korea’s first cosmetic ingredient blog after South Korea began requiring full ingredient labeling on packaging.
That research led to Isntree’s official launch in 2012 in Seoul, South Korea, built around a single premise: honest ingredients make the most effective skincare.
Today the label formulates sunscreens, toners, and serums distributed across more than 40 countries, still guided by the founder’s original commitment to transparency over trend-driven marketing.

Frequently Asked Questions
Answers to common questions about Isntree formulas and sun protection.
The Hyaluronic Acid Watery Sun Gel uses chemical UV filters such as Tinosorb S and Tinosorb M rather than mineral filters, so it is not classified as reef-safe. Customers seeking mineral protection should check individual product listings before purchase.
No. The watery gel texture absorbs quickly and sits nearly invisible on skin, which is one reason it remains popular among reviewers with deeper skin tones. A brief blue-tinted stage during blending is common and fades within minutes.
Yes. Formulas are built around centella asiatica, mugwort, and other calming botanicals, with over 2,000 potentially irritating ingredients excluded from every product. Patch testing is still recommended for reactive skin types.
Every product is formulated and produced in South Korea, where the brand is headquartered. Manufacturing follows the same transparency standards the founder established with Korea’s first ingredient-focused skincare blog.
The Onion Newpair collection is built around onion bulb extract, an ingredient long used in Korean herbal medicine, targeting uneven texture and dullness. It pairs well with brightening steps like the C-Niacin line.
Yes. No products or ingredients are tested on animals, and the brand does not use animal-derived materials in its formulations. Packaging has also shifted toward recyclable and FSC-certified materials since 2022.

Real feedback from skincare enthusiasts who added Isntree to their routine.
Sarah M.
This sun gel disappeared into my skin with zero white cast and kept me hydrated all day under makeup.
Tom B.
Sensitive skin here, and this is the only sunscreen that hasn’t caused redness. Absorbs fast and never feels heavy
Marcus T.
Lightweight, no greasy feel, and my sensitive skin never flared up once during three months of use.
Priya M.
Switched my whole family to the Sun Stick. Reapplying over makeup is finally easy and it never pills or feels sticky.
