Ingredient review
Dimethyl Phenylbutanol
INCI: Dimethyl Phenylbutanol
A synthetic scent ingredient that adds a pleasant floral note but offers no skincare benefits and may cause sensitivity in some people.
In plain English
Dimethyl Phenylbutanol is a lab-made chemical that smells like flowers or fruit. It is added to lotions, cleansers, and perfumes to make them smell nice. It does not moisturize, treat, or improve your skin in any way—it is purely for fragrance. While generally considered safe at low levels, it can sometimes cause irritation or allergic reactions, especially if you have sensitive skin.
