The shaping of eye brushes and lip brushes

To reach certain makeup effect, some brush bristles may need to have special shape. Some can be shaped by finishing or cutting, such as the angled blush brushes or angled eyebrow brushes. The angled blush brushes can be shaped during hair mounding; the angled eyebrow brushes can be shaped by cutting bristles. By the way, some may wonder why not cut the blush brushes too, that will be much easier for workers. That is because most blush brushes are made of animal hairs, which will become stiff after cutting, while the eyebrow brushes are made of synthetic hairs which will keep the softness after cutting.

Anyway, some bristles can not be shaped by finishing or cutting, and have to be shaped by special glue. For example, the pencil brushes, the eye liner brushes and lip brushes. These brushes require all bristles to be gathered into the center, such effect can not be reached by manual. Therefore, the makeup brush manufacturers will use some green (environmental protective) glue to fix the shape of bristles. Then after cetain period, the bristles will keep the shape even the glue is removed, dried or washed.

Usually, some glues will become powders after drying.If not, before shipment, the makeup brush factory will remove the glue by washing, because the glued bristles will be very stiff for makeup apply. Therefore, users will not find the existance of the glue.

Since the glue has been removed before shipment, some bristles may become deformed after reaching customers or users, even if we have add some tubes on some brush heads such as lip brushes to avoid of such deformation during shipment. However, such deformation will not affect the makeup effect, as the whole bristles are still gathering. If users really care such deformation, you can reshape the bristles by fixing them into a place for certain period, then they will be back to the normal shape.
