Hexahydro-Methanoinden-6-ol
INCI: HEXAHYDRO-METHANOINDEN-6-OL
A synthetic scent ingredient that adds a warm, woody note to products but offers no skin benefit and may cause sensitivity in some people.
In plain English
This is a man-made chemical that gives skincare and perfume a pleasant woody or amber-like smell. It doesn't moisturize, treat, or improve your skin in any way—it's purely there for fragrance. While generally considered safe at low levels, it can be irritating for those with sensitive skin or fragrance allergies.

What it is
Hexahydro-methanoinden-6-ol is a synthetic organic compound belonging to the family of indene derivatives. It is created in a lab to mimic natural woody or ambery scents and is used as a fragrance ingredient in cosmetics and personal care products.
How it works
In a cosmetic product, this ingredient simply evaporates from the skin's surface, releasing its scent molecules into the air. It does not interact with the skin's biology or provide any functional benefit beyond fragrance.
Pros
Pleasant scent
Provides a warm, woody, amber-like fragrance that many people find appealing in lotions, creams, and perfumes.
Low irritation for most
At typical low concentrations, it is generally non-irritating for the majority of users without fragrance sensitivities.
Cons and cautions
No skin benefit
This ingredient adds only scent—it does not hydrate, soothe, or improve skin health 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 skincare and have no history of fragrance allergies
- Those looking for a warm, woody scent profile
Use caution if
- Anyone with sensitive, reactive, or eczema-prone skin
- Individuals with known fragrance allergies or contact dermatitis
Usage tips
Safety summary
