Methoxy Tetramethyl Cyclohexenyl Methyl Ketone
INCI: METHOXY-TETRAMETHYL-CYCLOHEXENYL METHYL KETONE
A synthetic fragrance ingredient that adds a pleasant floral-woody scent but offers no skincare benefits and may cause sensitivity in some individuals.
In plain English
This is a man-made chemical used to give skincare and beauty products a specific scent, often described as floral or woody. It doesn't moisturize, protect, or treat the skin—it's purely for fragrance.

What it is
A synthetic organic compound belonging to the ketone family, specifically designed to impart a floral-woody fragrance to cosmetic formulations. It is not derived from plants or natural sources.
How it works
It works by evaporating from the skin's surface, releasing aromatic molecules that interact with olfactory receptors in the nose. In the product, it simply provides a pleasant scent to mask base odors or enhance the user experience.
