Ingredient review
Dimethylpyrazine
INCI: 2,5-DIMETHYLPYRAZINE
A synthetic fragrance compound that adds a nutty, roasted scent to products; generally safe at low levels but offers no skincare benefit.
In plain English
Dimethylpyrazine is a man-made chemical used to give cosmetics a pleasant nutty or roasted smell. It belongs to a family of compounds called pyrazines, which are found naturally in roasted coffee, cocoa, and grilled foods. In skincare, it is only used for fragrance and does not hydrate, exfoliate, or treat the skin. Because it is used in tiny amounts, it is unlikely to cause problems for most people, but those with very sensitive skin or fragrance allergies may want to avoid it.

- Step 2Use the "Best for" and "Use caution if" sections to match the ingredient to your skin, not just to a marketing claim.

Score terms in plain English
Irritation risk
lowLess likely to sting, burn, or bother most users, though sensitive skin can still react.
Clogging risk
lowLess likely to feel heavy or contribute to clogged pores for most skin types.
Evidence level

What it is
A synthetic aromatic organic compound from the pyrazine family, produced in a lab to mimic the nutty, earthy scent found in roasted foods. It is a clear to pale yellow liquid at room temperature.
How it works
It functions solely as a fragrance ingredient, contributing to the overall scent profile of a product. It does not interact with the skin's barrier or provide any active skincare function.
Pros
