Thin Lips Leeds
Causes & Treatment Options
Thin or undefined lips are a concern for patients across a wide age range – for some it is a lifelong characteristic, for others it is a change that has developed with age. The most effective treatment depends on what the patient actually wants to achieve, which is not always simply more volume.

What Causes Thin or Deflated Lips?
Genetics
Lip volume and shape are largely determined by genetics; naturally thin lips are a common and entirely normal variation.
Age-related volume loss
The lips lose volume progressively with age, becoming thinner and flatter.
Loss of lip border definition
The vermillion border softens with age, reducing the apparent definition and shape of the lips.
Perioral lines
Fine lines radiating from the lip border can make the lips appear smaller and contribute to an aged appearance.
Treatments at Dr Sebastian Bejma Aesthetics
Lip Filler (HA)
Hyaluronic acid filler is the primary treatment for lip volume, definition, border enhancement, and shape. At Dr Sebastian Bejma Aesthetics, lip treatment is always patient-led and guided by facial proportion – the goal is lips that look natural and balanced, not simply larger. A dental block is available for patients who prefer more comprehensive numbing.
Lip Flip (Botulinum Toxin)
A small amount of botulinum toxin placed into the orbicularis oris muscle causes the upper lip to relax and roll slightly outward, creating the appearance of a fuller upper lip without adding volume. A subtle, non-filler option suited to patients who want modest improvement in upper lip definition.
Perioral Lines Treatment
Fine lines around the lips can be addressed with a combination of approaches – botulinum toxin to reduce muscular contribution, filler for deeper lines, and skin resurfacing treatments such as microneedling or BioRePeel for surface-level texture improvement.
