What it is
A synthetic ester compound used as a fragrance ingredient in cosmetics. It is not derived from natural sources and is created in a lab to produce a specific scent profile.
How it works
It works by evaporating from the skin's surface and interacting with olfactory receptors in the nose, creating the perception of a fruity, fresh scent. It has no known functional role in skincare beyond fragrance.

Cons and cautions
No skincare benefit
This ingredient is purely for scent and does not moisturize, protect, or improve the skin in any way.
Allergen potential
Like many fragrance ingredients, it can cause allergic reactions or irritation in people with sensitive skin or fragrance allergies.
Best for
