This article explains the common reasons the lower face can look wide or full, how a doctor assesses them, and the types of options that may be discussed, including their limits and risks.
Face shape is mostly determined by bone structure, muscle, fat and skin, and these change over time. A lower face that looks square, wide or full can have different causes, so the right option for one person may not suit another. In this guide, our doctors explain what can make the jawline look wider, how the cause is assessed, and which surgical and non-surgical approaches may be discussed at a consultation.
Often more than one factor is involved, which is why an assessment comes first.
At a consultation, your doctor will look at your face at rest and while clenching, feel the jaw muscles, assess fat and skin quality, and ask about clenching, grinding, jaw pain and your medical history. Photos may be taken for your medical record. This helps identify whether muscle, fat, bone or skin laxity is the main contributor, and whether a non-surgical or surgical approach is more appropriate.
The right approach depends on the cause. Below are the types of options a doctor may discuss at a consultation.
Results depend on the cause and the option chosen, and they vary between individuals. Non-surgical changes are usually gradual and temporary, so maintenance may be discussed. Surgical options give a larger change but involve a longer recovery. Your doctor will explain realistic expectations before any treatment.

If teeth grinding (bruxism) is a concern, it is best to see a dentist or GP first for assessment. A doctor can then discuss whether any facial slimming option is relevant for you.
No. When done correctly, results are subtle and natural enhancing your existing features without altering your facial identity.
