What are dermal fillers?
Dermal fillers are materials injected into different areas of the face to reduce wrinkles and restore volume loss caused by aging, thereby providing a more youthful appearance.

Where can dermal fillers be applied?
Dermal fillers can be applied to many areas of the face. They may be used to restore volume in the cheekbones and cheeks to correct a sunken appearance, reduce nasolabial folds (the grooves extending downward from the sides of the nose), enhance lip fullness, reduce vertical lines around the mouth, improve deep acne scars and other scars, and correct hollows around the eyes.

What do dermal fillers contain?
Today, there are many different types of dermal fillers, each produced by various companies under different brand names. Hyaluronic acid is the most commonly used filler material. The risk of allergic reaction is very low, and if necessary it can be dissolved immediately with an enzyme called hyaluronidase. In addition to hyaluronic acid–based fillers, there are other fillers containing substances such as calcium hydroxyapatite and poly-L-lactic acid. Depending on their composition and density, fillers can be injected at different depths (superficial or deep layers). The duration of temporary fillers varies according to the type of material used and typically ranges between 6 and 24 months. For example, hyaluronic acid fillers usually last about 8–12 months, while fillers containing calcium hydroxyapatite may last approximately 1.5–2 years.

How is a filler procedure performed?
A topical anesthetic cream is applied to the treatment area approximately 30 minutes before the procedure. When necessary, a local anesthetic nerve block may also be performed about 15 minutes before the injection to completely numb the area.

How long does the filler procedure take, and what should I expect afterwards?
The procedure usually takes between 5 and 15 minutes depending on the size of the treated area. In most cases, patients can return to their normal daily activities immediately after the treatment. Mild swelling, redness, or sensitivity may occur but generally resolves quickly. If localized bruising develops, concealer may be used for about 3–4 days. When blunt-tip cannulas are used, vascular injury is minimized and swelling and bruising are typically mild.

How long do fillers last, and what happens afterwards?
Temporary fillers gradually dissolve over time. Depending on the material used and the treated area, their effects usually last between 6 and 24 months. After this period, filler injections can be repeated if desired.

Can fillers be combined with Botox?
Fillers and Botox can be applied during the same session in many areas of the face. However, in deep lines caused primarily by excessive muscle activity (such as the vertical lines between the eyebrows or around the lips), the ideal result is usually achieved by performing Botox first. About one week later, after the muscles have relaxed, superficial filler injections can be applied if needed.
