Hyaluronic acid that naturally exists in our body keeps the water in the skin to moisture it; and consequently, enables the skin to maintain its tightness and freshness. With increasing age, the amount of hyaluronic acid in our skin gradually decreases. This leads to the development of dynamic lines caused by the contraction of the facial expression muscles, as well as fine lines existing also during relaxation. With hyaluronic filler injections, it is possible to reduce the wrinkle and fine line formations in our skin, and to enable the skin to gain a fuller and younger appearance by increasing the water retention.
Hyaluronic acid filler applications are among the most widely used methods in the field of Medical Aesthetics. Deep wrinkles and collapsed or sagging cheeks disappear and the natural facial contours reappear with the aesthetic filling application that has been utilized for years, with intent to eliminate the fine lines on the face and add volume to the face.
What is a Filling Procedure ?
Our age and genes determine the general characteristics of our skin, the most important part of our external appearance. We often remain incapable to protect our genetic heritage against the negative effects of the environmental factors. Sunlight, air pollution, smoking, alcohol and caffeine use, stress, insomnia and malnutrition (lack of vitamins C and E) are the most important factors leading to premature aging of the skin. Hyaluronic acid-based substances can be injected with intent to correct deep lines that appear due to gravity, sun damage, hormones and aging; reduce wrinkles; make the skin look younger; and reshape the face.
Hyaluronic acid filler application is a treatment procedure requiring continuity and yearly follow-up processes for achieving the desired result. Duration of the effect varies from person to person. Hyaluronic acid is a type of absorbable filler. The absorption speed of hyaluronic acid preparations used in our clinic is low, and these preparations have a feature of maintaining their initial volumes throughout the absorption process. The more the gel is concentrated, the more water molecules it can bind. In conclusion, the same volume can be maintained with a less amount of filler. The filler completely melts and is absorbed in such a way as to leave no residues in the tissue.
What are the Fillers Used ?
Fillers can be classified in three categories as temporary, semi-permanent, or permanent. The most commonly used ones among temporary fillers are fillers that contain “hyaluronic acid”. Their durability periods vary from 6 months to 2 years.
Fillers that contain calcium hydroxyapatite (Radiesse) and poly-L-lactic acid (Sculptra) can be mentioned as semipermanent fillers. The durability periods of this type of fillers is about 2 years.
And permanent fillers are products that contain plastic (Bioalcamid), methacrylate (Artecoll), and liquid silicone. These fillers do not melt. But since they pose high risks, their use is not recommended.
Hyaluronic acid is the most commonly used filler. This material poses a very low risk, and can instantly be melted by means of a substance called ‘hyaluronidase’. It is a type of easy-to-use filler that protects both the patient and doctor in terms of being revocable.
Hyaluronic acid is one of the proteins that form the connective tissue between the cells of the human body. It can be considered to be joint filler between tiles. This substance is produced and presented to the consumer in such a way as to have different densities and different durability periods.
How Many Different Types of Hyaluronic Acid are Available ?
Hyaluronic acid products are generally in five types:
- Pure hyaluronic acid products that have no filling property but make the skin moisturized and fuller when applied subcutaneously.
- Fine fillers applied to fine lines such as crow’s feet and vertical lines on the lips.
- Fillers with intermediate density, which are applied to nose-lip lines, Marionette lines extending down from the edges of the lips, and frown lines between the eyebrows.
- Fillers developed for lip shaping.
- Deep fillers with high densities, which are applied to places just on the bones, with intent to accentuate the cheekbones, and augment the chin tip. Such fillers are also used for the purpose of hand regeneration.
Densities of fillers are directly proportional to their durability periods. Durability periods of deep fillers may be up to 2 years. Durability periods of fillers with intermediate density is generally 2 to 12 months.
Where is a Filler Used ?
- Nasolabial Lines (lines extending from the nose to the edges of the lips) down from the edge of the lip lines
- Tiny lines above the upper lip (perioral lines)
- Deep acne scars and wound scars
- Lip enhancement
- Cheekbone and cheek (malar augmentation)
Lip filler: In the course time, the lips begin to get thinner and lose their shape and fullness. Hyaluronic acid fillers can be used for enabling the lips to regain their fullness.
Grooves around the nose and mouth: Lines or grooves extending from the bottom of the nose to the area around the lips emerge as a result of the deflection of adipose tissues, and can be filled with hyaluronic acid or fat.
Cheeks, temples and jaw: As the amount of adipose tissue decreases, sagging and thinning start in those regions. Structuring the collagens with dense hyaluronic acid fillers gives excellent results in these areas.
Under eye bags and under eye hollowing: Under eye bags start from level of the bottom of the nasal bridge and the lower eyelid, and expands towards the cheeks. They can be treated with hyaluronic acid.
A better-balanced chin: With increasing age, the chin gets smaller and withdrawn. You can regain the lost appearance by applying hyaluronic acid fillers to the chin line, for solutions with short-term durability. Fillers are injected from the front and back of the jawbone, with intent to soften the chin line and obtain a better proportional chin. With bulking fillers, which are effective for a period of up to 18 months, it is possible to accentuate the facial oval, and enable the person to have a reverse triangle that adds an attractive appearance to the face.
Lifts the eyebrows: In the eyebrow region, the upper eyelids or droopy eyebrow can be lifted with hyaluronic acid fillers. When filler is injected into your eyebrow region, your eyebrows go up and you gain a more youthful appearance.
Is it Possible to Encounter Any Side Effects Due to Its Application ?
Despite being very rare, you may develop an allergy to the filler. Temporary damage, swelling, and redness are likely to occur. Side effects can be controlled in filling procedures carried out by an experienced physician specialized in the field.
No study has been conducted on its use during pregnancy and breastfeeding periods. Its use is not preferred in those who have a skin infection, allergic disease, bleeding or clotting problem, those who are receiving anticoagulant treatment, and those who have a keloid development story. You should inform your doctor if chemical peeling or any other operations have previously been done in the intended injection area.
