4. How to verify if you’re working with the factory, the trading company, or third party agents ? 

There are a few tricks you can use to get around this. Compare the writing on any business card you are given to the writing on the factory mast. Ask the person who’s giving you a tour to open random doors. If he or she needs to make 5 phone calls and wait 10 minutes for the door to be opened, then they’re not the factory owner.

5, In how many days a person can start noticing the difference? 

That depends on the condition of the users. for example,

1), Somebody's acne is in very bad condition, maybe he need longer time to get improvement.

2), But for the skin rejuvenation, such as moisturizing& skin tendering, the user can see the difference quickly. somebody in 2 treatment and somebody in 3-5 treatment.

3), And you should highlight to your customers that the device is designed for home use and the power is not that big as that the big beauty devices in salons and they should use it constantly. no more than 3 times a week and no more than 30 minutes per treatment.
