Product details

Fast hydration
A watery toner built on ultra-low molecular hyaluronic acid and Ulleungdo deep sea water, for moisture that sinks in within seconds.
Isntree layers more than a dozen forms of hyaluronic acid, from large barrier-forming molecules down to an ultra-low molecular one averaging 329 Da, over a base of mineral-rich deep sea water. The refreshing, watery texture absorbs quickly with a non-greasy finish and keeps skin hydrated for hours.

What’s inside
The ingredients doing the work
Complex hyaluronic acid
What Isntree calls its 14-layer complex: high molecular weights form a moisturizing barrier on top, medium and low weights hydrate deeper, and the ultra-low 329 Da form absorbs fast for longer-lasting moisture.
No. 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18 of 34 on the list
Ulleungdo deep sea water
Isntree’s signature ingredient, rich in magnesium, potassium, calcium and other minerals that hydrate skin and help stop moisture evaporating.
No. 4 of 34 on the list
Witch hazel + cypress leaf
Witch hazel helps skin’s natural turnover for a smoother texture, while Japanese cypress leaf soothes.
No. 33, 34 of 34 on the list
Soothing moisture
Gentle humectants and soothers, with a sugar-derived complex that helps strengthen the barrier and its moisturizing power.
No. 19, 20, 24, 29, 30, 31 of 34 on the list

Good to know

- Vegan, hypoallergenic formula that has been skin irritation tested, per Isntree.
- The box is recycled green tea paper printed with soy ink, and the bottle label peels off for recycling.
- 300 mL bottle.
