Ingredient review
Tomato Leaf Cell Culture Extract
INCI: Solanum Lycopersicum (Tomato) Leaf Cell Culture Extract
A gentle, lab-grown antioxidant from tomato leaves that helps defend skin against pollution and UV damage without irritation.
In plain English
This ingredient is made by growing tomato leaf cells in a lab, then extracting their beneficial compounds. It's rich in natural antioxidants like flavonoids and polyphenols that help neutralize free radicals—unstable molecules from sun exposure and pollution that can age skin. Because it's produced in a controlled environment, it's consistent, sustainable, and very gentle on skin.
