What should clients be advised after their facial steaming session?

After a facial steaming session, clients should be advised to avoid sun exposure. Facial steaming opens up the pores and can make the skin more sensitive and vulnerable to environmental factors, including the sun's UV rays. This heightened sensitivity can increase the risk of sunburn and other skin irritations. Therefore, protecting the skin from sun exposure is crucial to prevent damage and ensure that the benefits of the facial treatment are maintained.

Regarding the other choices, avoiding moisturization can lead to dry skin, as steaming can strip away natural oils. Not drinking water is not beneficial either, as hydration is essential for healthy skin. Lastly, continuing with a daily skincare routine is generally recommended, but care should be taken to select products that are appropriate for the skin's condition post-steaming. Therefore, advising clients to avoid sun exposure aligns best with skin protection after the facial treatment.
