How to Assess Lips Before Injecting

Before a needle ever touches the skin, a successful lip treatment begins with assessment. The shape, size, ratio, and symmetry of the lips, along with their relationship to other facial features, set the foundation for safe and natural results.

This guide introduces students to the essential principles of lip analysis—covering facial harmony, projection, proportion, and movement—while emphasising the importance of aligning patient expectations with what is achievable.

By learning to evaluate lips with precision, you’ll not only refine your injection technique but also deliver results that look natural, respect anatomy, and build long-term trust with your patients.
