Hyaluronic acid is the main product used to give volume to the lips and is found naturally in our body in the connective, epithelial and neural tissues.

The lips are soft, extremely mobile structures, located in the central part of the face and which can have different shapes and sizes depending on age, ethnicity, etc. As we age, we lose volume, including the lips, so that the lips become thinner, lose their contour and wrinkles appear in the perioral area.

When injecting lips with hyaluronic acid we must keep in mind the following rule:

• observance of the anatomy of the lips: at the level of the upper lip we have 3 tubers (protrusions) and at the level of the lower lip we have 2 tubers

• the ratio between the upper lip and the lower lip (golden ratio) should be 1 to 1,618 (the lower lip should be larger than the upper one).

• aesthetic considerations

• correction of asymmetries

• loss of lip volume with the aging process

• restoring the natural contour of the lips

One of the most serious complications related to the procedure of volumizing the lips with hyaluronic acid is the arterial occlusion that occurs after placing hyaluronic acid inside the vessel, in the case of the lips in the upper labial artery or the lower labial artery.The signs and symptoms of an arterial occlusion are:

• whitening of the area

• capillary pulse longer than 3 seconds

• pain that increases in intensity

• the appearance of areas with purple color that expands

Patients are taught to follow all the signs related to an arterial occlusion, and in case of one of the above symptoms the patient is obliged to contact the specialist urgently!!

• Avoid exposure to solarium, sun, sauna and intense cold for about a week after injection

• avoid intense physical exertion for one week after the procedure

• Avoid alcohol and smoking for 72 hours

• do not apply makeup on the injected area for 24 hours

• no other cosmetic or dental procedures will be performed in the next two weeks
