Which technique can help create a more pronounced lip shape?

Overlining the lips slightly with lip liner is an effective technique for creating a more pronounced lip shape. This method involves gently drawing the lip liner just outside the natural lip line, which can enhance the fullness and definition of the lips. By doing this, the illusion of larger, more sculpted lips is achieved, allowing for a more dramatic and defined appearance that is popular in many makeup styles.

In contrast, using a darker shade for the inner lip doesn't significantly contribute to the overall shape or size of the lips, and may instead create a shadow effect that can actually make the lips appear smaller. Applying only lip gloss adds shine and can enhance the color of the lips, but it does not alter their shape. Using a lip scrub before application is beneficial for lip care and can result in smoother application, but it does not directly influence the lip shape itself.
