“You should always use the same product line on your skin that is used in the spa where you work (If appropriate for your skin type) so your skin demonstrates how the product line can help your clients. You can’t educate and sell products that you don’t even use. You are representing how those products work. You MUST use the products, not just one piece of the product line, but you need to use many of the products so you can educate the customer on how the product line helped your skin. They need to see that you practice what you preach.”
