Suction blister grafting involves the creation of blisters on a donor site such as the thigh.  The upper layer of skin (epidermis) is removed from the Vitiligo area being treated.  The roof of the blister is then carefully removed and placed on the prepared Vitiligo area.  Pigment cells from the graft begin moving into the Vitiligo area within a week.  Re-pigmentation is usually complete within three months.
