A permanent medical tattoo can be applied on the scar in cases when excision of the postoperative scar and restoration of the latter by using the W-plasty or FUE technique is not indicated. Micropigmentation is the technique that lately has gained momentum regarding scar restoration. During the application of micropigmentation, the scar is being covered by little spots or fine lines that resemble the image of short cut hair.
The micropigmentation technique should be solely applied by experienced and well-qualified medical personnel in conditions of absolute sterilization. In all cases, the procedure takes place under local anaesthesia. Moreover during the micropigmentation sessions attention should be paid to the proper sterilization of the medical tools and of course special caution should be given so that substances that secure a safe and aesthetically satisfying outcome are being applied so as no allergies or side effects are being caused. One should pay attention to the fact that micropigmentation does not restore the scar, it solely conceals it. It is another option though to improve the aesthetic appearance of the scar.
The main disadvantage of micropigmentation is the fact that significant side effects such as infection or allergy might be observed due to the application of inappropriate colourant or because of the usage of medical tools non sterilized adequately enough. Moreover, despite the fact that the outcome might look successful at the beginning, overtime one might observe discoloration or even bleaching of the tattoo. It is not a rare phenomenon that gradually the colour of the tattoo ends up to an unnatural one such as green or blue – a colour that does not resemble the natural colour of hair, of course.
The discoloration happens because of the intense hematosis of the head that results in the breakdown of the colourant. An additional element that leads to the discoloration of the tattoo is the exposure to the sun, especially when there is not enough hair density in the area. Therefore, a major disadvantage is the fact that it is required repetition of the micropigmentation procedure in order to preserve a natural result. One session is not enough to achieve a satisfying outcome, despite what a professional might promise to a patient.
