How can estheticians ensure the safety of their products?

Estheticians can ensure the safety of their products by regularly checking expiration dates. Expiration dates are provided by manufacturers to indicate the period during which a product remains effective and safe to use. Using products past their expiration date can lead to degraded ingredients, ineffective results, or unexpected skin reactions. Regular checks help maintain product integrity and client safety, ensuring that only safe and effective products are used during treatments.

The other choices do not enhance product safety. Mixing old products with new ones can lead to unpredictable chemical reactions, potentially creating ineffective or harmful mixtures. Storing products at room temperature may not be appropriate for all items, especially those that require refrigeration to maintain their efficacy. Removing product labels can create confusion about expiration dates and usage instructions, significantly increasing the risk of using unsafe products.
