What it is
A synthetic organic compound from the ether family, specifically designed to impart a fresh, woody, and slightly floral fragrance to cosmetic formulations.
How it works
It evaporates from the skin's surface after application, releasing its scent molecules into the air. It does not interact with skin cells or provide any functional skincare benefit beyond fragrance.
Pros
Pleasant scent
Adds a fresh, woody note that many users find appealing and can make the product feel more luxurious.
Low irritation for most
At typical low concentrations, it is generally well-tolerated by most skin types without causing redness or stinging.
Cons and cautions
No skin benefit
This ingredient exists solely for fragrance—it does not hydrate, soothe, or improve skin health in any way.
Potential allergen
As a synthetic fragrance, it can still trigger contact dermatitis or allergic reactions in sensitive individuals, especially with repeated use.
Best for
- Anyone who enjoys a fresh, woody scent in their skincare routine
- Users without fragrance sensitivities looking for a pleasant sensory experience
Use caution if
- People with sensitive, reactive, or allergy-prone skin who prefer fragrance-free products
