Ask how the counter handles testing

A clean-looking cap does not tell you how a tester was used previously. Ask staff what testing methods are available and whether you can inspect sealed ingredient information. If a hygienic test is not available, use product descriptions and the store’s purchase terms instead of taking an avoidable risk.

Separate a color check from a wear trial

A hand swatch can help compare hue and finish, while a personal lip application answers a different question. If you cannot test a formula appropriately at the counter, do not treat the hand result as a complete comfort or long-wear test.

Keep your own products personal

Do not share applicators or use a friend’s lipstick directly. Keep caps and tools clean. If you have a reaction to a product, stop using it and preserve its identifying details for the manufacturer or your healthcare professional. We do not recommend a universal at-home sanitation procedure that makes shared products safe.

Before you decide

  • Ask staff about testing hygiene.
  • Use a new applicator for each application.
  • Treat a swatch as limited color information.
