In the scenario where a movie star is setting up a company to sell her own make-up brand, the most relevant type of intellectual property she would use to show that the make-up is made by her company is trademarks.
Trademarks can help her establish a brand identity and protect the name, logo, and any distinctive features of her makeup line, helping consumers recognize the products as being from her company. Other forms of intellectual property mentioned, such as patents, copyright, geographical indications, and registered designs, serve different purposes and may not be directly relevant to branding her makeup products.
