What it is
A synthetic ester compound used exclusively as a fragrance ingredient in cosmetics and personal care products. It is not naturally derived and is produced through chemical synthesis.
How it works
It evaporates from the skin's surface, releasing a pleasant scent that interacts with your sense of smell. It has no active effect on the skin itself.
Pros
Pleasant scent
Adds a sweet, floral, or balsamic note that can make your skincare routine feel more luxurious.
Low irritation for most
At typical low concentrations, it is generally well-tolerated by people without fragrance sensitivities.
Cons and cautions
No skincare benefit
This ingredient only provides scent—it does not moisturize, protect, or improve your skin in any way.
Potential allergen
Like many synthetic fragrances, it can trigger allergic reactions or irritation in people with sensitive skin or fragrance allergies.
Best for
- People who enjoy scented products and have no history of fragrance sensitivity
- Those looking for a pleasant sensory experience in their routine
Use caution if
- Individuals with known fragrance allergies or sensitive, reactive skin
