Lip injections create fuller lips.
There are three main types of lip injections in use: fat-based, collagen-based, and hyaluronic acid-based. Each type has advantages and disadvantages. Neither of these substances will provide permanent lip fillers. The results of lip injections usually last between four and six months. Substances used in injections gradually break down and are absorbed over time.
Lip injections can use fat, collagen, or hyaluronic acid to increase the size of a person’s lips.
Fat transfer is a process in which fat is removed from the individual’s body, via liposuction or incision, and then injected into the lips. Since the fat comes from the person receiving the injection, rejection is unlikely. The fat creates a natural looking lip. Fat injections generally do not last as long as collagen or hyaluronic acid injections.
Some bruising is expected after a lip injection procedure.
Hyaluronic acid injections use a clear gel similar to hyaluronic acid naturally present in the body. Hyaluronic acid is responsible for lubricating the joints and is also present in the skin. Hyaluronic acid-based lip injections retain water in the body, enhancing the plumping effect of the injection. These products usually last about six months.
People with active cold sores should avoid lip injections.
Collagen is the most common product used for lip injections all over the world. Collagen can come from cows or humans. Bovine-based collagen comes from cows that are raised in a closed herd to prevent contamination. Some people are allergic to bovine collagen, so the doctor will do a skin test before injecting it into the lips. Human-derived collagen is removed from cadavers or excess skin is removed during surgery. Allergy testing is not required during this procedure.
Patients will receive topical anesthesia prior to injection into the lips.
Lip injections create fuller lips that are considered youthful. As people age, it is normal for the lips to become thinner. The procedure is quick and relatively painless. Although the skin around the lips is extremely thin and sensitive, the needles used for the injections are very small in diameter and the patient is given topical anesthesia before the injections.
After the lip injection procedure, it is normal for the patient to have bruising and swelling for a few days to a week. Possible side effects include uneven lips, difficulty moving the lips, or bleeding. The most common side effects are swelling, itching at the injection sites, and redness. Some people may be allergic to lidocaine, the topical anesthetic used in the procedure. People with active cold sores, lip scars, blood clotting disorders, diabetes, or lupus should avoid lip injections.
