What Is Hyaluronic Acid Filler?

Hyaluronic acid filler is a medical application used by injecting it under the skin to add volume, reduce wrinkles, and shape facial features. Hyaluronic acid is a polysaccharide naturally found in the human body and has a high water-retention capacity. Thanks to this property, it provides moisture, elasticity, and vitality to the skin tissue.

The applied filler restores the volume the skin gradually loses over time, resulting in a younger, more dynamic, and balanced appearance.

How Is Hyaluronic Acid Filler Applied?

Hyaluronic acid filler should be administered in a sterile environment by a qualified physician. A topical anesthetic cream is applied to the area before the procedure to minimize any discomfort during the treatment. The filler is injected under the skin using fine needles or special cannulas.

The procedure typically takes between 20–40 minutes. Depending on individual needs, it can be applied to various areas such as the lips, cheekbones, jawline, nasolabial region (between the nose and lips), or under the eyes. The amount of filler is determined according to facial proportions and skin structure.

Who Can Receive Hyaluronic Acid Filler?

This procedure is suitable for individuals experiencing volume loss in facial features, concerned about wrinkles or hollow areas, and wishing to achieve a more defined and balanced facial structure.

Filler application is not recommended during pregnancy, breastfeeding, or in the presence of an active infection. Additionally, individuals with a history of allergic reactions must be examined by a physician before the procedure.

How Long Does the Effect of Hyaluronic Acid Filler Last?

The longevity of hyaluronic acid fillers varies depending on the density of the product used, the area of application, the individual's age, and metabolic rate. Generally, their effects last between 6 to 18 months.

Over time, the filler is naturally broken down and absorbed by the body. Therefore, once its effect diminishes, the filler can be safely reapplied. To prolong the longevity of the filler, it is important to maintain adequate hydration, follow a regular skincare routine, and avoid smoking and alcohol.

Advantages and Key Features of Hyaluronic Acid Filler

Hyaluronic acid filler stands out for not requiring surgery and being made of natural ingredients. Additionally, its ability to be reabsorbed by the body increases the safety of the procedure.

Provides a natural and balanced appearance.
Recovery time after the procedure is very short.
Supports skin quality and moisture balance.
Can be dissolved with the enzyme “hyaluronidase” if desired.

These features have made hyaluronic acid filler one of the most preferred methods for both facial rejuvenation and contouring procedures.

Precautions to Take After Hyaluronic Acid Filler

During the first 24–48 hours after the procedure, mild swelling, redness, or sensitivity may occur on the skin. This is temporary and usually disappears completely within a few days. It is recommended not to apply makeup, avoid massaging the area, and refrain from sauna, steam baths, and intense exercise during the first 24 hours.

Additionally, avoiding touching the treated area and sleeping with the head elevated can reduce the risk of swelling. Avoiding direct sunlight and drinking plenty of water helps the filler settle more effectively in the skin.
