Isntree
Sold out
A 100 ml leave-on exfoliating essence at a brand-published 8 percent AHA, buffered with chestnut extract, which gives the Isntree Chestnut line its name and its softer character. The 100 ml bottle is deliberately large for an acid: in Korea an exfoliating essence is applied over the whole face on scheduled nights, not dabbed on trouble spots.
Who it's for. Rough, flaky texture and dull-looking skin. Not for skin that is currently irritated, and to be introduced slowly on sensitive skin.
How to use. Evenings only, starting two to three times a week. After toner, apply a thin even layer with the fingertips and make a single pass per zone; going back over the same area is what turns a mild acid into a stinging one. Follow with moisturizer. Sunscreen every morning is not optional while you use an acid.
Key active. AHA at a brand-published 8 percent, an exfoliating acid that loosens dead cells at the surface, with chestnut extract as a conditioning botanical.
Sourced in Seoul. This is the Korean domestic SKU, not a reformulated export version.
