Black pigment is a pre-modified color to be neutral shade and age gracefully by going out of the skin in black and dull grey shades, avoiding blue and other funky undertones.
We still suggest to modify it with extra warmth, using MARA Pro Black together with Red Pepper color corrector just for a prevention.
Suggested proportion for the initial session is 6:4 Black:Red Pepper and can be adjusted to less or more Red Pepper at the touch up based on how dark it heals.
