In a facial aesthetic clinic, the term “fillers” refers to dermal fillers — injectable substances used to restore volume, smooth out wrinkles, enhance facial contours, and rejuvenate the skin’s appearance.

What are fillers?

Most fillers are made of hyaluronic acid, a substance naturally found in the body that helps keep skin hydrated and plump. Other types include calcium hydroxylapatite and poly-L-lactic acid, but hyaluronic acid fillers are the most commonly used due to their safety and reversibility.

Common aesthetic uses:

• Lip enhancement (adding volume or defining the lip border)
• Under-eye hollows (tear trough correction)
• Nasolabial folds (smile lines or “laugh lines”)
• Jawline and chin definition (facial harmonization)
• Cheekbone enhancement (adding volume and lift)
• Temples, nose reshaping (non-surgical rhinoplasty), and facial contouring

Benefits:

• Immediate results
• Minimally invasive, quick procedure
• Effects typically last 6 months to 18 months, depending on the product and area treated
• Hyaluronic acid fillers can be dissolved with an enzyme (hyaluronidase) if needed

Difference between fillers and Botox:

• Botox: relaxes facial muscles to reduce dynamic wrinkles (caused by movement)
• Fillers: add volume or fill in static wrinkles (visible even at rest)
