What it is
A synthetic organic compound from the tricyclodecane family, specifically designed as a fragrance ingredient. It is not found in nature and is produced through chemical synthesis.
How it works
It works by binding to olfactory receptors in the nose, creating the perception of a woody, amber-like scent. In a cosmetic product, it simply contributes to the overall fragrance profile and has no functional skincare benefit.
Pros
Pleasant scent profile
Adds a warm, woody, and slightly amber-like fragrance that many people find appealing and sophisticated.
