Comedogenic Rating

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

Is Bis(Tripeptide-1) Copper Acetate a Good Ingredient?

Visible firming claims in leave-on products have only modest support, and results depend on the full formula, which is why it's rated Fair. A minority of users may also experience mild irritation or sensitivity to copper complexes.
