Lightly sketch the scar’s shape with a thin line
Decide whether the scar is straight, curved, jagged, or raised
Draw the outline slightly uneven for a natural look
Add small breaks or irregular edges if the scar is old
Shade one side of the scar slightly darker
Add a thin highlight along the opposite edge
Blend the shading softly into the surrounding skin
Use a muted pink, red, brown, or pale tone depending on the scar age
Add subtle texture with tiny lines or dots if needed
Darken the center slightly for deeper scars
Keep the scar narrower at the ends if it tapers
Erase harsh lines and soften the edges
Adjust contrast to match the lighting of the drawing
