Rosemary Flower Extract
INCI: Rosmarinus Officinalis Flower Extract
A gentle antioxidant extract from rosemary flowers that helps protect skin from environmental stress without causing irritation.
In plain English
Rosemary Flower Extract is a natural ingredient made from the flowers of the rosemary plant. In skincare, it works as an antioxidant, meaning it helps protect your skin from damage caused by things like pollution and UV rays. It also has mild soothing properties, which can help calm redness or irritation. Because it comes from flowers rather than leaves, it is generally very gentle and unlikely to clog pores or cause breakouts.
