Safety
When treating the perioral region, be aware of the position of blood vessels especially the superior labial artery. Swelling and bruising are common, more so than in other areas.
Anatomy
The repeated mechanical movement of the orbicularis oris muscle causes wrinkles to form around the mouth (e.g. smoker’s lines). Loss in bone density and gum atrophy also adds to the problem. Fine lines in the area are often accompanied by a loss of definition of the philtrum and vermillion border. The vermillion border is the demarcation between the lips and the surrounding skin. The cupids bow is the central part of the upper lip with two peaks forming the philtrum. The cupids bow contributes to the natural shape of the lip and is typically enhanced as part of the dermal filler lip augmentation.
The lip can be divided into dry and wet mucosa. When the mouth is closed, the dry mucosa is exposed to air and the wet mucosa remains inside the mouth. The junction between these two portions of the lip is called the wet-dry border. Lip shape and volume varies greatly. In general, the lower lip is fuller than the upper lip.

Treatment Specific Side Effects
Vermillion Border Enhancement:
The treatment consists of linear thread injections for the upper and lower lip borders. Injections are place in the superficial dermis of the vermillion border.
Lip Volume Enhancement:
This treatment is suitable for those with a loss of volume in their lips or for the purpose of cosmetic enhancement. The technique used in lip volume enhancement is retrograde linear injections. Dermal ller is injected approximately 2 mm deep in the mucosa, at or just superior to the wet–dry border.
