Final answer:
Post-care for a chemical or mechanical exfoliation treatment typically lasts between 5 to 7 days, focusing on protection and gentle care to ensure proper skin healing and to avoid complications.
Step-by-step explanation:
Post-service instructions for a chemical or mechanical (physical) exfoliation typically require detailed post-care for a specific period after treatment. The exact number of days for post-care can vary depending on the type of exfoliation, the strength of the chemical agents used, and individual skin sensitivity. Generally, post-care instructions are crucial for ensuring proper healing and preventing complications such as irritation or infection. The recommended period for following these instructions is often between 5 to 7 days after the treatment. During this time, clients are usually advised to avoid sun exposure, refrain from using other exfoliating products, and keep the skin moisturized and protected.
