Dermal fillers are injectable cosmetic dermatology treatments used to replace volume loss for smooth, youthful skin, full lips, and general rejuvenation of the appearance, including treating acne-scarred skin.

There are numerous different types of injectable fillers made from materials like collagen, hyaluronic acid, and calcium hydroxyapatite.

• Bellafill – a collagen filler that delivers long-lasting results (up to five years) as well as stimulating the body's natural production of collagen and elastin. This dermal filler can be used for fine lines and wrinkles on any part of the face as well as improving the appearance of acne scars.

• Belotero – a hyaluronic acid filler used for moderate to deep fine lines and wrinkles, including frown lines, crow's feet, and forehead wrinkles.

• JuvedermPopular – another hyaluronic acid filler, Juvederm actually has a range of dermal filler products that are each geared toward improving the appearance of lines and wrinkles in specific areas.

• RadiessePopular – a synthetic filler that is used to treat fine lines and wrinkles in all areas, and in some cases, it may be a viable alternative to surgical cosmetic dermatology solutions to improve the fullness and appearance of skin with more severe volume loss. It is known as a biostimulator.

• RestylanePopular – another hyaluronic acid filler, Restylane also has a line of products that are formulated to address specific areas of need.

• SculptraPopular – a synthetic filler often used to treat moderate to severe frown and marionette lines while stimulating your body's natural collagen production for long-lasting results. It is known as a biostimulator.

Dermal fillers are not permanent, but the results of most treatments will last between six and twenty-four months.

Dermal fillers may be combined with neurotoxin injections and other cosmetic dermatology treatments to deliver an overall improved appearance.

For the most part, properly administered dermal filler treatments will have few, if any, side effects. There may be some redness or bruising at the injection site, but this typically resolves very quickly.
