How can you best check for client noncompliance regarding their skincare routine?

Checking your client's product usage history provides a definitive way to assess noncompliance with their skincare routine. This method involves reviewing the records or logs of the products your client has purchased and whether they have been using them as recommended. By analyzing their usage patterns, you can identify any discrepancies in their adherence to the prescribed routine.

While questioning clients about their product usage can provide insights, it relies on their self-reporting, which can sometimes be subjective and influenced by various factors such as embarrassment or forgetfulness. Observing the condition of the client's skin may indicate some level of adherence or issues, but it does not specify which products were or weren't used and why. Similarly, monitoring acne extracts may not give a complete picture, as skin conditions can arise from various factors beyond product noncompliance. Therefore, reviewing the product usage history stands out as the most reliable method to accurately assess whether clients are following their skincare regimen.
