Ingredient review
3,5-Dimethyl Cyclohexenecarbonitrile
INCI: 3,5-DIMETHYL CYCLOHEXENECARBONITRILE
A synthetic scent ingredient that adds a fresh citrus note but may cause irritation in sensitive individuals.
In plain English
This is a man-made chemical added to skincare and beauty products to give them a pleasant, fresh, citrus-like smell. It doesn't provide any skin benefits like moisturizing or anti-aging—it's purely for fragrance. Because it's a fragrance ingredient, it can sometimes cause skin irritation or allergic reactions, especially if you have sensitive skin or a known fragrance allergy.

What it is
A synthetic organic compound from the nitrile family, created in a lab to mimic fresh, citrusy scents. It is not derived from plants or natural sources.
How it works
It works by releasing volatile molecules that interact with olfactory receptors in your nose, creating the perception of a fresh, citrusy scent. In a product, it simply adds fragrance and has no active skincare function.
Pros

Low comedogenic risk
Unlikely to clog pores, so it's generally safe for acne-prone skin if you're not sensitive to fragrance.
Cons and cautions
Potential irritant
Can cause redness, itching, or stinging in people with sensitive skin or fragrance allergies.
No skin benefit
Provides only scent, not hydration, repair, or any active skincare function.
Best for
