A double lip line is when you can visibly see two distinct borders around your lips: the natural outer edge of the lip and a second line just beyond it. This second line is actually the vermillion border, the demarcation line between the lip itself and the surrounding skin.
According to celebrity makeup artist Mila Thomas, "A double lip line is when you can clearly see the natural, outer edge of your lips, as well as a second border around the lips." She explains that this second border is technically called the vermillion border, which is "the line of demarcation between the lip and the skin around it."
Here's a breakdown:
| Feature | Description |
|---|---|
| Natural Lip Edge | The visible outer edge of the fleshy part of your lips. |
| Vermillion Border | The line where the lip skin meets the regular skin around your mouth; this line sometimes appears as a second, visible border, creating a 'double lip line'. |
This phenomenon isn't necessarily a beauty defect; some individuals naturally have a more pronounced vermillion border than others.
