Score terms in plain English

Irritation risk

moderate

Can bother some users, especially with frequent use, damaged skin, or strong companion ingredients.

Clogging risk

low

Less likely to feel heavy or contribute to clogged pores for most skin types.

Evidence level

emerging

What it is

A synthetic ketone compound derived from carene, a natural terpene found in pine and cedar oils. It is manufactured for use as a fragrance ingredient in cosmetics and personal care products.

How it works

It works by binding to olfactory receptors in the nose, creating a perception of a fresh, woody scent. In a product, it simply contributes to the overall fragrance profile and has no known functional skin benefit.

Pros

Unique scent profile

Offers a fresh, woody, or spicy note that can make a product feel more luxurious and enjoyable to use.

Low concentration needed

Only a tiny amount is required to achieve the desired fragrance, minimizing overall exposure.

Cons and cautions

Potential irritant

As a synthetic fragrance, it may cause redness, itching, or stinging in people with sensitive skin or fragrance allergies.

Limited research

There is less published safety and efficacy data for this specific compound compared to more common fragrance ingredients, so its long-term effects are less understood.

Best for

  • People who enjoy scented skincare and have no history of fragrance allergies
  • Those looking for a unique, woody fragrance note

Use caution if

  • Individuals with sensitive skin, eczema, or known fragrance allergies

Usage tips

If you have sensitive skin, patch test any product containing this ingredient on a small area before full use.
Look for products that list the specific fragrance ingredient rather than just 'parfum' if you want to avoid certain compounds.

Safety summary
