Dermal fillers are injectable substances placed beneath the skin to restore volume, smooth lines, and enhance facial contours. They work by occupying space under the skin's surface, lifting sagging areas and filling depressions caused by aging or loss of fat. Options range from temporary formulations like hyaluronic acid that the body gradually absorbs, to longer-lasting options like calcium hydroxylapatite and poly-L-lactic acid that stimulate collagen production, to semi-permanent and permanent choices like PMMA and silicone. Different fillers suit different areas and goals, with some designed specifically for lips, hands, or deep facial lines.

Fillers suit people seeking to address volume loss, hollow areas, fine lines, or asymmetry without surgery. Common reasons include restoring cheek fullness, plumping lips, softening nasolabial folds, or rejuvenating aging hands. A qualified provider will evaluate your skin, discuss your aesthetic goals, and recommend which filler type and placement will work best for your anatomy and desired outcome.

Most filler appointments take 15 to 45 minutes depending on how many areas are treated. A provider typically applies topical numbing cream or uses ice for comfort, then injects the filler with a fine needle or blunt cannula into targeted areas. Sensations range from mild pressure to brief stinging; most patients tolerate the procedure well.

Most people resume normal activities immediately after filler injection. Mild swelling, redness, and bruising are common and typically fade within a few days. Providers often recommend avoiding vigorous exercise, extreme heat, and certain medications for the first 24 to 48 hours.

Results appear immediately after injection, though swelling may mask the final appearance for a few days. Longevity depends on the filler type and individual metabolism; temporary fillers may last 3 to 12 months, longer-lasting options may persist for 1 to 3 years or more, and some semi-permanent and permanent choices are designed to be long-term or indefinite. Touch-up appointments help maintain desired results.
