What side effects may there be after tattooing eyebrows?

Does eyebrow tattoo surgery have any side effects? It has something to do with the quality of eyebrow tattoo liquid. If inferior eyebrow tattoo liquid is used, it will cause epithelial granuloma after eyebrow tattoo. At present, it is considered that this lesion may be related to carbon, titanium oxide, iron oxide and impurities in eyebrow tattoo solution. Lesions after eyebrow tattooing will lead to red, itchy and painful induration in the eyebrow tattooing area. This kind of lesion has not been effectively treated, and it often needs surgical resection and re-repair, which makes tattooers miserable, so it is very important to choose a regular eyebrow tattoo hospital.
