# Mouth

The **Mouth** tool in Aperty offers fine-tuning options for adjusting the shape and position of the lips. This allows you to subtly enhance the lips' appearance to create a balanced and natural look in your portrait.

* **Lips Position**: Adjusts the vertical placement of the lips on the face. Moving the slider upward raises the lips while moving it downward lowers them. This is useful for correcting the overall facial balance and aligning the lips with other facial features, such as the nose and chin.
* **Upper Lip Shape**: Modifies the shape and size of the upper lip. Increasing this slider enhances the fullness of the upper lip, making it appear more defined or plump. Lowering it reduces the prominence of the upper lip, giving it a thinner appearance. Adjust this to achieve a balanced lip shape that fits the subject’s facial proportions.
* **Lower Lip Shape**: Adjusts the shape and size of the lower lip. Increasing this slider makes the lower lip fuller and more rounded while decreasing it creates a thinner, subtler lower lip. This can complement the adjustments made to the upper lip and maintain overall symmetry.

{% hint style="info" %}
When adjusting the lips, use the Lips Position slider to ensure they are aligned with other facial features. Make subtle changes to the Upper Lip Shape and Lower Lip Shape to enhance fullness while maintaining natural proportions, ensuring the lips fit seamlessly into the overall facial structure.
