At Heyday, we use only genuine products because we receives and 

uses products through an official purchase process with pharmaceutical companies. 

You can rest assured of the procedure.

Although the difference in effect is not significant, imported products (xeomin)

have the advantage that resistance in the process is relatively less 

than that of domestic products. You can take this into consideration when making your choice.

It usually doesn't happen, but it can happen sometimes. 

If it does, it will improve within about 1-2 weeks, so you don't have to worry too much.

It works better when combined with savescarp and plasma.
