Micropigmentation for vitiligo, scalp, for scars, for stretchmarks ​is a technique in which minute, metabolically inert pigment granules are implanted below the epidermis for cosmetic and/or corrective enhancement. Typically two to four treatments are necessary. The process can be performed in a doctor’s office in less than two hours. Topical anesthetics are sometimes applied to keep the patient comfortable during the procedure. Pigments are individually mixed to match the patient’s skin. Results can be seen immediately, though full end results are not apparent for about three weeks.
