What is the recommended depth of needle insertion for eyebrow PMU?

The recommended depth of needle insertion for eyebrow permanent makeup (PMU) is typically between 1 to 2 millimeters. This depth is crucial for several reasons. At this range, the pigment can effectively deposit into the dermal layer of the skin, where it can hold for a longer duration without risking excessive trauma or potential scarring to the skin. The upper dermis is where color retention is optimal, ensuring that the results are visible and long-lasting while also minimizing pain and recovery time for the client.

Going deeper than this, such as in the 2 to 3 millimeter range, could lead to complications, including increased bleeding, pain, and a higher likelihood of scarring or color migration, which can adversely affect the results. Therefore, the 1 to 2 millimeter range is widely acknowledged as the best practice for achieving desirable outcomes in eyebrow PMU while maintaining client safety and comfort.
