Possibly. The existing work must first be evaluated.
Correction depends on the current pigment color, depth, density, shape of the hairline, size of the impressions, and condition of the skin. If the previous SMP is light or faded, it may be possible to improve the pattern, add density, or adjust the color.
If the pigment is very dark, heavily saturated, blue-gray, or placed outside the desired shape, adding more pigment may not produce a natural result. In those cases, fading or removal may need to be considered first. Clear photos in natural daylight are required before scheduling.
