Patent number: 6344188Abstract: A wrinkle reducing cream is presented which reduces wrinkles upon topical application to the skin. The main ingredients of the composition include a water and caffeine composition which is mixed together in a first vessel and a glycerin composition heated in a second vessel. The three components of the active ingredient are mixed carefully, making sure that any precipitate produced is remixed into the solution. After heating and mixing the components, the entire composition is cooled with care being taken to push any precipitate back into solution to ensure an even distribution of all of the components. The active ingredient thus produced may be combined with a suitable cosmetic vehicle to provide the topical wrinkle reducing composition. The composition is topically applied to the wrinkled area over a period of days or months in order to reduce or entirely eliminate wrinkles from the skin. The final active ingredient may also be used for other applications.Type: GrantFiled: March 1, 2000Date of Patent: February 5, 2002Assignee: Victor Silva, Inc.Inventors: Victor Silva, Bryan K.
