What characteristic distinguishes permanent makeup from traditional makeup?

The characteristic that distinguishes permanent makeup from traditional makeup is that permanent makeup is applied onto the skin. Unlike traditional makeup products, which can be easily applied and removed, permanent makeup involves the use of techniques that implant pigment into the skin, similar to tattooing. This leads to a long-lasting effect that is designed to mimic the look of traditional cosmetics.

The other options do not accurately represent the fundamental nature of permanent makeup. For instance, the idea that permanent makeup can be easily changed contradicts its design, as changing it typically requires additional procedures. While some permanent makeup products may utilize natural pigments, this is not a defining feature that sets them apart from traditional makeup, which can also use natural ingredients. Lastly, the claim that permanent makeup fades after a short period is misleading, as it is intended to last for an extended time, although it may necessitate touch-ups due to fading over the years. Thus, the key aspect of permanent makeup being applied onto the skin clearly differentiates it from traditional makeup.
