Cis-Isoocimenol
INCI: CIS-ISOOCIMENOL
Cis-Isoocimenol is a synthetic fragrance ingredient that adds a fresh scent but may cause irritation in sensitive individuals.
In plain English
Cis-Isoocimenol is a man-made chemical that perfumers use to create a fresh, green, or floral smell in skincare and beauty products. It is not a natural plant extract but is designed to mimic or enhance certain scents. Because it is a fragrance ingredient, it is usually present in very tiny amounts, but it can still be a potential irritant for people with sensitive skin or fragrance allergies.

What it is
Cis-Isoocimenol is a synthetic organic compound belonging to the terpene family, specifically an isomer of ocimenol. It is produced through chemical synthesis and is used exclusively as a fragrance ingredient in cosmetics and personal care products.
How it works
In a cosmetic product, Cis-Isoocimenol contributes to the overall scent profile by providing a fresh, green, or floral note. It does not have any active skincare benefits like moisturizing or exfoliating; its sole purpose is to make the product smell pleasant. It evaporates from the skin over time, leaving the fragrance behind.
Pros
Pleasant scent
Adds a fresh, green, or floral note that many people find appealing in their skincare products.
Low concentration needed
Only a tiny amount is required to achieve the desired fragrance, so it is used sparingly in formulations.
Cons and cautions
Potential irritant
Can cause redness, itching, or stinging in people with sensitive skin or fragrance allergies, especially with repeated use.
No skincare benefit
Provides only scent and does not hydrate, protect, or improve the skin in any way.
Best for
- People who enjoy scented skincare and do not have fragrance sensitivities
- Those looking for a fresh, green scent in their products
Use caution if
- Individuals with known fragrance allergies or very sensitive skin
- Anyone following a fragrance-free skincare routine
Usage tips
