Microblading with previous Permanent Makeup
Clients with previous Permanent Makeup are considered to be more challenging to work with when Microblading. Once you have an eyebrow tattoo, it limits design process since the tattoo must be worked around. The perfect shape may not be able to be created.
In order to use the Microblading technique the brow must have some negative space where the hair strokes can be drawn. The tattoo color will not be covered up by the hair strokes.
Another thing to consider is scar tissue. Depending on the artwork, the brow area most likely developed scar tissue which makes the skin harder to scratch resulting in a lower chance that the pigment will be retained.
Faded brow tattoos are easier to work on as long as the pigment does not appear red or purple (tattoo color can change over time).
