What are airplane regulations for makeup?

Airplane regulations regarding makeup primarily focus on the transportation of cosmetics in carry-on and checked baggage. Liquids, gels, and creams must comply with the 3-1-1 rule, meaning they should be in containers of 3.4 ounces (100 milliliters) or less, packed in a single quart-sized plastic bag. Solid makeup products, such as powders and lipsticks, generally do not have the same restrictions. It's advisable to check with specific airlines for any additional guidelines.
