Colloidal copper is toxic to a wide range of bacteria and fungi. Although it is used less commonly than colloidal silver, colloidal copper is gaining popularity as a treatment for several types of dermatological problems, including acne.
Copper-based compounds are the active ingredient in many anti-fungal, topical solutions. Copper has also been incorporated into fabrics and bandages to slow the growth of disease and odor-causing bacteria. Copper peptides, which are small molecules that are composed of short chains of amino acids connected to copper ions, are also the subject of research efforts for dermatological applications. They are being used in a number of rejuvenating and skin revitalizing treatments.
Colloidal copper and copper salts (copper sulfate) are frequently used in many branches of Naturopathic Medicine. However, the efficacy of copper therapies for the treatment of acne remains largely untested by rigorous clinical trials. More research is needed to determine whether the use of colloidal copper (and other colloidal metals, such as Silver) can significantly improve symptoms for individuals with acne.
