K-Beauty Makeup Testers and Eye Cosmetics: Hygiene Questions Answered
A Q&A on using makeup testers and caring for eye cosmetics, with guidance from the U.S. FDA.
Trying Korean makeup in a store can help you compare a shade or texture, but shared testers and eye-area products deserve extra care. These answers draw on U.S. Food and Drug Administration (FDA) consumer guidance and apply to cosmetics generally, including K-Beauty products.
Can I share a makeup tester?
The FDA advises against sharing makeup because infections can be passed between people. It notes that store testers are more likely to become contaminated than products used at home. If you decide to test a cosmetic, the agency recommends a new, unused applicator, such as a fresh cotton swab.
What should I check before trying eye makeup?
Wash your hands before applying eye cosmetics and keep tools that touch the eye area clean. The FDA advises avoiding eye cosmetics when you have an eye infection or inflamed skin around the eye, and discarding eye cosmetics used when the infection occurred. If a product irritates your eyes, stop using it; seek medical advice if irritation persists.
Can I revive dry mascara?
Do not add water or saliva to dried mascara. The FDA recommends discarding it because added liquid can introduce microorganisms. Keep containers clean, and follow the product instructions for storage and use.
A checklist for shopping and use
- Ask the retailer how testers are handled and use a new applicator if you decide to try a product.
- Keep personal makeup and eye-area applicators for your own use.
- Check the specific package instructions, warnings and product condition before use.
- Do not leave cosmetics exposed to excessive heat, such as in a hot car.
- For practical tool care, consult THE CAST’s makeup brush cleaning guide linked below.
These precautions do not guarantee that a product is free of contamination. If an eye problem continues, speak with a qualified healthcare professional.
