The injection therapy is performed on an outpatient basis. If the forehead is to be lifted, then an overnight stay could be necessary.
1. Non Lasting Materials - Absorbable:
Collagen is a protein that takes on a supporting function in various body tissues. It can be found in the skin, the joints, bones and ligaments. The collagen used for injection treatments (used for deep-layer treatments) is produced from purified bovine collagen. The purifying procedure produces collagen very similar to human tissue. It is offered in various concentrations to meet the various demands of patients.
Collagen – can be used to fill in finer and deeper lines, folds and scars in the face and neck. It is the filling material most commonly used.
Hyaluronic acid – as a substance of human connective tissue, hyaluronic acid can be found in such places as the skin. Contrary to collagen, no real allergies are known. Products consisting of pure hyaluronic acid are particularly suitable for treating the fine lines in the face, as it can be directly injected in the surface skin similar to the diluted concentrations of collagen.
Fatty tissue – in general, fatty tissue from the abdomen, the thighs, the buttocks or other areas is taken from the patient for treatments to reduce wrinkles. This method is termed “autologous fat transplantation“ among experts. Fat is mainly used to fill in sunken cheeks, to correct laugh lines in the lower part of the face, to refill indentations, to reduce horizontal lines in the forehead and to make lips fuller. In all the places where larger amounts of injection material are needed, using the body’s own fat can make sense.
Botulin toxin (Botox®, Dysport®), a neurotoxin (the poison of the Clostridium botulinum), causes the muscles used for facial expression to relax. The drug acts as an “anti-hardener” that blocks the transfer of commands from the nerve to the muscle to contract for approximately 3 to 5 months. This treatment is therefore especially suitable for the so-called “frown lines” and “worrying creases” on the forehead as well as the “crow’s feet” on the outer edges of the eye. The drug Botulinum toxin is injected to the area in a very diluted dosage. Aside from very few, small needle points that are only visible for a short time, the treatment leaves no traces. The effect kicks in about 2 to 3 days after the injection and lasts for approximately 6 to 9 months.
2. Lasting Materials:
Gortex, a fine-threaded material used implanted to support the subcutis – mainly used to produce fuller lips.
Artecoll - The collagen in this substance contains up to 25% fine plastic particles that lead to smoothing the surface skin by forming a kind of inner scar consisting of autogenous tissue in the deeper skin layer. Little by little, the collagen injected together with this material is absorbed by the body. In the end, the skin is smoothed by having filled the area underneath with autogenous tissue.
Your plastic surgeon will gladly provide you with more detailed information on the various types of material used and together you can choose the method of treatment that suits you most.
The length of the injection treatment depends on the type and extent of the treatment chosen. When using fatty tissue from the body, you must also include the time for the removal of fatty tissue in advance.
A negative allergy test is required before a collagen treatment. As soon as the local anesthetic has begun to be effective, the sterilized skin is injected with a fine needle along the various points of the line to be treated. As the water in the collagen solution only takes a few days to be absorbed by the body, your doctor will strive to slightly overfill the designated area.
The procedure is similar to all treatments with foreign materials (hyaluronic acid, artecoll).
The areas to be treated are sterilized and given local anesthesia, then fatty tissue is removed through suction using a hollow needle or cannula. The fatty tissue is then prepared for the injection and administered with a thin needle to the designated area. As in the procedure with collagen, a slight “overfilling” is necessary, as a part of the injected fatty tissue will soon be absorbed. For the treatment of sunken cheeks, for example, the impression of slight swelling is made by the overfill in the area, yet this will disappear within a short period.
For some materials to be injected – e.g. collagen, a local anaesthetic is added to the substance so that generally no additional anaesthesia is necessary.
Most other materials to be injected require no anaesthesia, however if you are sensitive to pain or if a very extensive treatment awaits you, then additional anaesthetic cream is recommended. Furthermore there is the possibility of using a local anaesthetic or a mild sedative for eliminating pain. Sedatives can be given as a pill or by an intravenous injection to make you drowsy.
Local anaesthesia is common in the area where fatty tissue is to be removed as well as in the area to be injected. For larger procedures, it can make sense to receive an additional sedative.
