Fillers, also known as dermal fillers or soft tissue fillers, represent a category of cosmetic procedures aimed at rejuvenating the skin, enhancing facial contours, and addressing signs of aging. These treatments involve injecting specialized substances into targeted areas of the face to diminish wrinkles, restore lost volume, and achieve a smoother, more youthful appearance.

The most common types of fillers are composed of materials like hyaluronic acid, calcium hydroxylapatite, poly-L-lactic acid, and polymethylmethacrylate (PMMA), each offering unique properties and longevity. Hyaluronic acid fillers, for instance, are prized for their ability to attract and retain moisture, effectively plumping up the skin and reducing the appearance of lines and wrinkles. Calcium hydroxylapatite fillers stimulate collagen production, providing longer-lasting volume enhancement. Poly-L-lactic acid stimulates collagen production over time, resulting in gradual and natural-looking improvement. PMMA fillers provide semi-permanent results by creating a matrix that supports collagen production and tissue growth.

Filler treatments are versatile and can address various aesthetic concerns across different facial regions. Common treatment areas include the nasolabial folds (smile lines), marionette lines (lines around the mouth), lips (for volume enhancement or reshaping), cheeks (to restore volume and lift), under-eye hollows, temples, chin, and jawline.
