Loretta uses Atomic Force Microscopy (AFM) to generate nanotopographic images of the surface of the analyzed samples. Loretta primarly analyzes corneocytes, collected in a non-invasive manner using dermatological adhesive tape from any area of the body. This topographic method is effective on all skin types, regardless of age, skin tone, or health condition. Thanks to Loretta's fast AFM method, you obtain quantitative, verifiable, and high-precision results to accurately determine the efficacy of your products.
