Comedogenic Rating

This ingredient is not typically evaluated for comedogenicity, and no standardized rating is available.

Safety

Generally considered safe at the low levels used in cosmetics, but its volatility can trigger irritation or sensitization, especially on sensitive or compromised skin. Patch testing or opting for fragrance-free products is prudent if you're reactive.

Is Gamma-Undecalactone a Good Ingredient?

It's Fair because it adds a pleasant peachy note but no skin-care benefit, and evidence for any skin effect is minimal. As a volatile fragrance, it carries a sensitization and irritation risk for fragrance-reactive users, which is what holds it at Fair.
