Can You Bring Lipstick On A Plane? Lipstick is normally permitted in a carry-on suitcase while traveling by plane. Lipstick is categorized as a solid cosmetic and is exempt from the same regulations that apply to liquids or gels. However, it's always a good idea to confirm any revised policies or limits with the specific airline or with the competent transportation security organization. The lipstick container may be subject to additional inspection or may need to be carried in your checked luggage rather than your carry-on if it exceeds the maximum size restriction for liquids, which is typically 3.4 ounces or 100 milliliters.
