Carbon based pigments are less forgiving than Iron Oxide pigments and they have a higher chance of migration due to its particle size.
Your client may want a wing now, but in 5-10 years that same client may have a change of heart. Use an Iron Oxide on wings and wedges.
Carbon black has the smallest particle size.
Due to Carbon’s very small particle size, it requires less pressure to implant. This is why you should be on point with your depth and confident in your technique before you try Carbon based pigments.
Migration happens due to too much pressure.
If Carbon outlasts all the other colorants…that leaves a gray, blue or gray/blue eyeliner just depending on the type of Carbon used and how the pigment was formulated.
