The effect of injecting hyaluronic acid into head tattoo is immediate, and the stability of the drug needs about 1 week. Do not touch the injection site within 48 hours to avoid deformation and displacement affecting the appearance. Please follow the doctor's advice for special parts.

The effect of one injection usually lasts about 6- 12 months, and hyaluronic acid will be gradually metabolized and absorbed. If the injection is supplemented during this period, the effect will be more lasting. Of course, different individuals and different parts will be different.
