Keep important products original
Medication, sunscreen, contact-lens products, and anything whose dosage, stability, or instructions matter may need to remain in its original container. Follow the product directions and applicable transport rules.
Test before travel
Fill each container, close it, place it in a sealed pouch, and leave it on different sides overnight. Recheck the seal after cleaning. Never combine products in one container.
