Do you ever think to make a survey by sending small cosmetic trail pack?

Nowadays, more and more skin care brands like to study millennial consumers. Obviously, the young generation is a big potential spending power. It is said one cosmetic brand held an activity among different cities about their new products for youth. This activity was to send out the trial pack (cream/ cleanser packing with small plastic tube packaging)

The activity is successful. They received much active feedback from the consumers, and started to design a series of skin care packaging.
