In plain English

This ingredient is a man-made compound used to give products a pleasant woody or amber-like smell. It's not a moisturizer or active skincare ingredient—its only job is to make the product smell nice. Because it's a fragrance ingredient, it doesn't provide any skin benefits, and people with very sensitive skin or fragrance allergies might want to avoid it.

What it is

A synthetic organic compound belonging to the family of fragrance ingredients. It is created in a lab to mimic natural woody or amber scents and is used in many perfumed cosmetics.
