Isntree Green Tea Fresh Serum: A Lightweight Green Tea Serum for Oily-Dehydrated Skin

Isntree is a Korean dermatology-partnered brand with a reputation for straightforward, ingredient-forward products at accessible prices. The Green Tea Fresh Serum is their take on the popular green tea serum category, positioned for users with oily-dehydrated skin (a common condition where skin produces excess sebum in response to surface dehydration). The formula is water-light, non-greasy, and focused on hydration without heaviness.

Compared to innisfree's green tea serum (the category benchmark), Isntree's is lighter in texture and more oily-skin-optimized. Green tea provides antioxidant support, sebum regulation, and mild antimicrobial action on acne-prone skin. The brand sources their green tea from Korean green tea farms, consistent with Isntree's single-ingredient-forward positioning.

What It Does

Green tea extract delivers catechins (EGCG) for antioxidant protection and mild sebum regulation. Hyaluronic acid provides hydration without heaviness. Niacinamide adds brightening and sebum control support. The watery texture absorbs in under 30 seconds, leaving no tacky residue.
