Restrictions exist regarding the types and quantities of cosmetic and personal care items permitted in carry-on and checked baggage when traveling by air. These regulations primarily relate to the volume of liquids, aerosols, and gels. Generally, individual containers must not exceed 3.4 ounces (100 milliliters), and all such containers must fit comfortably in a single, quart-sized, clear plastic zip-top bag. Items exceeding this size restriction are typically prohibited in carry-on luggage, though exceptions may exist for essential medications or baby formula.
Adhering to these guidelines is vital for maintaining airport security and ensuring a smooth travel experience. Failure to comply can lead to confiscation of skincare products, delays at security checkpoints, and potential inconvenience. Historically, these regulations were implemented in response to security threats involving liquid explosives. They aim to mitigate risks while permitting passengers to bring essential personal care items.
