Filling consists of an intradermal or subcutaneous injection of substances, which have properties to reduce wrinkles:
- hyaluronic acid,
- hyaluronic acid combined with acrylic hydrogel,
- mixture of water and polyacrylamide,
- collagen preparations.
The procedure involves injecting small amounts of compounds which contain hyaluronic acid with use of very tiny needles. It is usually used to remove nasolabial folds, wrinkles around the lips, furrows between eyebrows, i.e. the so-called gravitational wrinkles. Filling procedures with use of hyaluronic acid do not cause any side effects. Action of hyaluronic acid involves binding water molecules in the skin, thus increasing its elasticity and flexibility. Hyaluronic acid is the most frequently used filler. This is a compound which forms the surface of the skin by binding water molecules in the skin, which stabilizes the structure by filling the volume between the cells of the tissue, leading to increased firmness and restored youthful appearance of the skin. Hyaluronic acid perfectly fills nasolabial folds, wrinkles around the lips, wrinkles of the cheeks and corrects drooping corners of the mouth. It causes that skin regains its elasticity, wrinkles disappear and the face retains its natural look.
The procedure consists in injecting of tiny portions of gel into the skin with use of very thin needle which minimises pain. Before the procedure, infiltration anaesthesia is performed. Directly after the procedure, swelling, redness, itching and discolouration may occur. Symptoms disappear after 2 - 4 days. Effect of the procedure is visible for approx. one year.
Other fillers contain preparations on the basis of polylactic acid (a particle which is naturally present is our bodies).
Procedures with polylactic acid are completely safe and provide long-lasting effect. Tests for allergies are not made before the procedure because polylactic acid does not contain particles which may allergies.
Polylactic acid fills the wrinkles. After several days, water in the gel is absorbed and correction effect is withdrawn. Afterwards, the particles of polylactic acid intensify synthesis process of collagen (protein responsible for skin’s elasticity) which leads to natural recovery of the skin. The number of treatments depends on the individual needs and expectations. On average, 2 to 4 procedures should be performed at the interval of 2, 4 and 6 weeks. The minimum interval between treatments is 15 days. Effect is visible for 2 to 5 years.
To sustain the effects, treatment must be repeated every 1-2 years.
There are two types of indications for the procedure: filling (increasing the volume) and correction of wrinkles. Preparations are used to correct sunken cheeks and face oval, to remove nasolabial folds and to correct dropped lip corners. Before the procedure, skin is anaesthetised with EMLA or regional anaesthesia is performed. After the treatment, the following temporary reactions such as swelling, redness or haematomas. All reactions subside after several days. Opaque makeup can be made directly after the procedure. Preparations with polylactic acid smooth furrows and wrinkles.
