The sales were not so bad even though it was just the first day. The staff were kind of expected that the product would be well received by the customers. They knew because they already tried the products themselves.
Their boss told them to try the products themselves. She said if they wanted to sell the products better, they needed to understand the products better. To understand the products, the best way was to use the products themselves.
They were told by the factory workers that their boss used the same products. Then, they braved themselves trying the products. Turns out, after only a few days of trying, their faces looked better than before.
Because they knew the effects of the products, they answered the questions given by the customers so confidently.
Like...
"Yes, madame. The effects could be seen in a few days. I also tried the products myself. After a few days, my skin becomes smooth and brighter."
