What it is
Dihydroanethole is a synthetic aromatic compound derived from anethole, the natural scent molecule in anise and fennel. It is used as a fragrance ingredient in cosmetics and personal care products.
How it works
In a cosmetic product, dihydroanethole dissolves into the formula and releases a sweet, licorice-like aroma. It does not actively interact with the skin; its sole purpose is to provide a pleasant scent.
Pros
Pleasant scent
Adds a sweet, anise-like fragrance that many find appealing in lotions and cleansers.
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
Dihydroanethole is purely a fragrance ingredient and does not moisturize, soothe, or improve skin health.
Potential allergen
Like many synthetic fragrances, it can trigger contact dermatitis or allergic reactions in sensitive individuals.
Best for
- People who enjoy sweet, licorice-like scents in their products
- Those without fragrance sensitivities
Use caution if
- Individuals with known fragrance allergies or very sensitive skin
- Anyone preferring fragrance-free skincare
