2. Both modern eyebrow tattoo technology and semi-permanent makeup technology claim that pigments are pure plants, which can be directly absorbed and metabolized by the skin without any side effects, but this may not be the case.
3. At present, the top pigments will be metabolized within 2 years, and the lighter ones will take 3 to 5 years. In this process, pigment will enter the human microcirculation. If they are pregnant during pregnancy, the microcirculation will reach the abdomen.
No matter whether the other party says pure plants or completely absorbed, you won't see such words in the quality inspection report. Pure plants are just a formula proportion. For example, three 9' s pure gold and four 9' s pure gold are all called pure gold. However, no one has ever said that the ratio is 100%, and there will always be a shortage. The purity of pigment market is far from such a high proportion of plants. You can't even dye your nails during pregnancy. That's still on your fingernail, and this has entered the skin layer.
It is not recommended that people who plan to get pregnant get tattoos on their eyebrows, including during breastfeeding.
