Ingredient review
Tetrahydromyrcenyl Acetate
INCI: TETRAHYDROMYRCENYL ACETATE
A synthetic scent ingredient that adds a fresh, citrusy note to products but offers no direct skin benefit.
In plain English
Tetrahydromyrcenyl acetate is a man-made chemical that smells like fresh citrus or a light floral. It is added to skincare and beauty products purely for its pleasant scent, not to improve your skin. Because it is a fragrance ingredient, it can sometimes cause irritation or allergic reactions in sensitive individuals, though it is generally considered safe at the low levels used in cosmetics.

What it is
A synthetic ester derived from myrcene, a naturally occurring terpene found in plants like hops and lemongrass. It is chemically modified to create a stable, pleasant-smelling compound used in perfumery and cosmetics.
How it works
It evaporates from the skin's surface, releasing a fresh, citrusy aroma that enhances the user's sensory experience. It does not interact with skin cells or provide any functional skincare benefit.
Pros
Pleasant scent
Adds a fresh, uplifting citrus note that makes your skincare routine feel more enjoyable.
Low irritation potential for most
At typical low concentrations, it is well-tolerated by the majority of skin types.
Cons and cautions
No skin benefit
This ingredient is purely for fragrance and does not hydrate, protect, or repair the skin.
Potential allergen
As a synthetic fragrance, it can trigger contact dermatitis or allergic reactions in sensitive individuals.
Best for
- Anyone who enjoys a light, citrusy scent in their skincare
- People without fragrance sensitivities looking for a pleasant sensory experience
Use caution if
- Individuals with known fragrance allergies or sensitive, reactive skin
