Permanent makeup, also known as cosmetic tattooing or micropigmentation, involves the application of pigments into the skin's dermal layer to enhance features such as eyebrows, eyelids, lips, and even the skin itself. Here's a breakdown:

1. Eyebrows: Permanent makeup can fill in sparse eyebrows or reshape them to achieve a desired look. Techniques include microblading, where fine lines are etched into the skin to mimic natural hair strokes, or shading, which creates a denser, filled-in appearance.

2. Eyeliner: This procedure involves tattooing pigment along the lash line to enhance the eyes' appearance. It can range from subtle, tightlining to more dramatic styles like winged eyeliner.

3. Lips: Permanent lip makeup can add definition, fullness, and color to the lips. Techniques include lip liner tattooing to define the lip shape, full lip color for adding pigment to the entire lip area, or lip blush for a subtle tint.
