Final answer:
Clients should discontinue the use of exfoliants for 24 hours following a wax service to prevent skin irritation and inflammation.
Step-by-step explanation:
After a waxing service, it is recommended that clients should discontinue the use of exfoliants for 24 hours. Exfoliation after waxing can irritate the skin since waxing itself already exfoliates and removes the top layer of skin. Giving the skin time to recover helps prevent potential inflammation, sensitivity, or further skin damage. Therefore, the correct answer to the question, 'How long should a client discontinue the use of exfoliants following a wax service?' is d. 24 hours. The client should discontinue the use of exfoliants for 24 hours following a wax service. This is because waxing can cause temporary inflammation and sensitivity in the skin, and using exfoliants immediately after can further irritate the skin and potentially cause redness or discomfort. It is important to give the skin time to recover before resuming exfoliation.
