What role do product labels play in esthetician practices?

Product labels are fundamental in esthetician practices because they provide essential information regarding usage and safety. This information is critical for estheticians to ensure that the products used on clients are appropriate for their skin types and conditions. Safety details inform practitioners about potential allergens, contraindications, and instructions that must be followed to avoid adverse reactions. Furthermore, understanding the correct usage aids estheticians in providing optimal results while maintaining client safety. Labels often include guidelines about how much of a product to use, how often to apply it, and other important details that can affect the efficacy of the treatment and the overall experience for the client.

The other options do touch on aspects of product labels but do not capture their primary purpose in professional practice. For example, while product labels can serve as marketing tools or include testimonials, these aspects are secondary compared to the crucial safety and usage information that is vital for informed practice in esthetics.
