Isntree is the quiet overachiever of K-beauty. No viral TikTok moments, no flashy packaging — just consistently excellent products at budget prices.

This is a brand for people who read ingredient lists and appreciate understated excellence.

8/10 · moisturizerGreen Tea Fresh Emulsion
An impressive lightweight moisturizer built around 80% green tea extract, which provides antioxidant protection and mild sebum regulation. The emulsion format is ideal for oily and combination skin — it provides adequate moisture without any heaviness or greasiness. The addition of niacinamide adds brightening and pore-refining benefits. It won't be enough moisture for dry skin types, but for oily skin that needs hydration without weight, this is one of the smartest budget options available.

8/10 · tonerClear Skin 8% AHA Essence
Isntree's exfoliating toner combines BHA (betaine salicylate) with glycolic acid for a dual-action approach to pore congestion and dullness. It's more effective than most exfoliating toners at this price, though the betaine salicylate is gentler than pure salicylic acid — which is both a strength for sensitive users and a limitation for those with stubborn acne. Best used 2-3 times per week rather than daily. An understated but effective exfoliant that delivers visible texture improvement.
