Overview / Definition

Lip Fillers are a type of dermal filler specifically designed to enhance the volume, shape, and symmetry of the lips. They are commonly made from hyaluronic acid, a naturally occurring substance in the body that adds hydration and plumpness.

Lip fillers are used for:

• Enhancing lip fullness and contour
  
  
• Correcting asymmetry
  
  
• Smoothing fine lines around the mouth (perioral lines)
  
  
• Rejuvenating ageing lips
  
  

Treatment can be subtle for natural enhancement or more pronounced for a bold aesthetic effect.

History

Lip augmentation has a long history, with early methods including paraffin injections and collagen. Hyaluronic acid-based fillers emerged in the 1990s, offering safer, reversible, and more natural results. Lip enhancement has since become one of the most requested non-surgical cosmetic treatments globally, driven by media influence and social trends.

Training & Regulation

In the UK, lip fillers are prescription-only and must be administered by:

• Registered healthcare professionals (doctor, dentist, nurse, pharmacist)
  
  
• Practitioners trained in facial anatomy, injection techniques, and complication management
  
  

Lip filler procedures are regulated by the Medicines and Healthcare products Regulatory Agency (MHRA). Check a Treatment does not verify practitioners, and clients should confirm qualifications, insurance, and experience independently.

Some training may be CPD accredited, but not all courses are. Clients should review practitioner profiles for CPD confirmation.
