The 3-1-1 rule is a TSA guideline for carry-on liquids. It means each liquid item must be 3.4 ounces (100 milliliters) or less, all liquids must be placed in one quart-sized, clear plastic zip-top bag, and one bag is allowed per passenger.

Determining the 'No. 1' makeup brand is subjective and depends on factors like sales, popularity, and consumer surveys. However, brands like L'Oréal, Maybelline, and Estée Lauder are consistently ranked among the top globally due to their broad product ranges and market presence.

TJ Maxx sells makeup at discounted prices because they purchase overstock, discontinued items, or products from past seasons directly from brands or distributors. This allows them to offer makeup at prices lower than traditional retail.

Defining the 'top 10' is subjective, but popular and highly-rated brands include: L'Oréal, Maybelline, Estée Lauder, MAC Cosmetics, Fenty Beauty, NARS Cosmetics, Dior, Chanel, Lancôme, and Urban Decay. The best brand depends on individual preferences, skin type, and desired product performance.
