Eyebrow fibrosis Eyebrow fibrosis (phibrows) is a new method for doing eyebrows and eyebrow shadows. At the same time, the appearance of the eyebrows is quite similar to real eyebrows. The microbuilding pen is used to perform eyebrow shading and shading based on the fibrosis method. The needles used in this pen are disposable and are replaced after each use (although some pens are completely disposable and are replaced after each use), which is very important from a health point of view.
