TSA's 3-1-1 rule shapes how most travelers pack beauty products.

The rule

Liquids, gels and creams in carry-on bags go in containers of 3.4 oz (100 ml) or less, all in one quart-size bag. Check TSA's site for current rules.

Solid swaps

Solid shampoo, stick sunscreen and powder cleansers save space in your liquids bag.

Packing tips

Leave a little air in refillable bottles and pack them upright.
