A synthetic scent ingredient that adds a fresh floral note but offers no skincare benefit and may cause sensitivity in some people.

What it is
A synthetic ester compound used as a fragrance ingredient in cosmetics and personal care products. It is created in a lab to produce a specific scent profile.
How it works
It evaporates from the skin's surface, releasing scent molecules that are detected by the nose. It does not interact with skin biology or provide any functional skincare benefit.
Pros
Pleasant scent
Adds a fresh, floral note that can make your skincare routine feel more luxurious and enjoyable.
Low irritation for most
At typical low concentrations, it is unlikely to cause problems for people without fragrance sensitivities.
Cons and cautions
No skin benefit
This ingredient is purely for scent—it doesn't moisturize, protect, or improve skin health in any way.
Potential allergen
Like many fragrance ingredients, it can cause contact dermatitis or allergic reactions in sensitive individuals, especially with repeated use.
Best for
- People who enjoy scented products and have no fragrance sensitivities
