A synthetic fragrance ingredient that adds a pleasant floral note but offers no skincare benefit and may cause sensitivity in some individuals.
In plain English

What it is
A synthetic organic compound from the cyclohexanone family, used exclusively as a fragrance ingredient in cosmetics and personal care products.
How it works
It evaporates from the skin's surface, releasing scent molecules that are detected by the nose. It has no active skincare function and does not interact with the skin's biology in a beneficial way.

Low risk at low levels
At typical use concentrations, it has a low irritation and comedogenic risk for most skin types.
