Yemima Catherine – What should be prepared before doing embroidery procedure?

The first thing is of course you look for a suitable PMU artist and determine the schedule, because each PMU artist has their own style. Then consult first with your PMU artist.
for example for eyebrows, you can request the shape & color. Then for example for lips, the skin of the lips should not be too dry. So it must be moisturized before doing the lip embroidery procedure.
For eyeliner embroidery, make sure you are not wearing false eyelashes / eyelash extensions.
