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

What it is

A synthetic aromatic compound derived from eugenol, used primarily 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 spicy, clove-like scent. In a product, it simply adds fragrance and has no functional skincare benefit.

Pros
