Step-by-step explanation:
An esthetician should ask about a client's lifestyle and describe any observations about the skin's appearance before the treatment. This is because understanding a client's lifestyle, such as their daily routine, diet, and stress levels, can provide important insights into the condition of their skin. By asking about the client's lifestyle, an esthetician can identify potential factors that may be impacting the health and appearance of the skin, and tailor the treatment accordingly. This personalized understanding paves the way for bespoke treatments, finely calibrated to address specific concerns.
