Lip Filler Program The Definition of Beautiful Lips

Lips are an important organ for social expression and have a significant impact on sexual attraction. The anatomy of beautiful lips consists of

- The white line between the mucosa and the skin is clearly visible.
- Has a Cupid’s bow in a "V" shape.
- Lips are plump (Fulfilled medial tubercle and vermillion)
- The edges of the lips point upwards (Ascendant line in the oral commissures).

By the golden ratio, the proportion between the upper lip and the lower lip is 1:1.618.

 

Interesting anatomy of the lips

- The upper lip is thinner than the lower lip.
- The upper lip has less subcutaneous fat than the lower lip.
- The majority of the lip muscles are the orbicularis oris muscle.
- The fibers around the lips function as a sphincter of the mouth.
- Other muscles around the mouth also play different roles in expressing various facial expressions.
 

  Muscles that lift the lip (Levators)

  - labii superioris alaeque nasi levator muscles

  - labii superioris levator muscles

  - zygomatic minor and major muscles

  - risorius muscles

  Depressor muscles

  - Depressor anguli oris muscles

  - Depressor labii inferioris muscles

  - Mentalis muscles

  The blood vessels that supply the upper and lower lips are the superior labial arteries and inferior labial arteries, respectively. Both branches are located in the submucosa layer and branch off from the facial artery.

  Sensory nerves

  - The upper lip is the infraorbital nerve.
  - The lower lip is the mental nerve.

  Nerve that controls the muscles
  - Orbicularis oris: buccal branches of the facial nerve

  - Other surrounding muscles: buccal or marginal branches of the facial nerve

 

 

Who is it suitable for

- The issue of lip shape depends on each individual patient and should be evaluated by a specialist doctor in both static and dynamic situations.
- Younger patients who desire lip augmentation
- Elderly patients often have both a decrease in lip volume and deep lines around the mouth (perioral radial grooves). Therefore, lip filler injections are suitable for elderly patients who want to increase lip volume, and these deep lines around the mouth should also be addressed.

 

What techniques are there?

Injecting filler in the lip area is quite painful, so nerve blocking should be performed by a qualified doctor as follows

- Upper lip: Inject to block the infraorbital nerve, followed by injecting lidocaine into the submucosal layer both outside and inside toward the frenulum linguae.

- Lower lip: Inject to block the mentalis nerve followed by injecting lidocaine into the submucosal layer.

 - Intraoral approach is less painful than transcutaneous approach. 

 - After the anesthesia injection is complete, start injecting from the Cupid’s bow or oral commissure.

  - It is recommended to use retrograde injection rather than serial techniques because serial techniques may cause bleeding spots or an unproportioned lip shape.

 - Inject the edges of the lips with collagen to mimic the natural white line.

 - Inject hyaluronic acid to enhance the prominence of the vermillion, always considering the structure of the teeth as well.
 - Inject to enhance the projection of the inner tubercle until achieving a beautiful lip shape.
