Tinted lipstick and lip SPF are separate label questions

Look for the actual sunscreen information

Do not infer SPF from a deep shade, a thick texture or a social-media description. FDA distinguishes cosmetics from products that also have drug uses, including sunscreen. The label must answer the protection question; a color swatch cannot.

Follow the application and reapplication directions

Read the amount, timing and reapplication information on the selected sunscreen product. Eating, drinking and wiping can be relevant to the routine, so carry a product you can use as directed. This guide does not assign an SPF to a homemade combination of lipstick and balm.

Keep color layering claims modest

Adding a colored product may change the cosmetic appearance, but we have not tested whether any particular layering method preserves a sunscreen film. Ask the manufacturer if the intended combination is unclear. Use other sun-protection measures as appropriate rather than relying on an unverified makeup combination.

Before you decide

• Check for real sunscreen labeling.
• Follow that product’s directions.
• Do not calculate a combined SPF by adding numbers.
