Dermal Fillers

Dermal fillers are FDA-approved and used for the cosmetic treatment of fine facial lines, wrinkles, and folds. Injectable dermal fillers can also be used to plump or add volume to thin lips. Dermal fillers are composed of hyaluronic acid, a naturally occurring substance found in every living cell. Fillers contain synthetic gel forms of hyaluronic acid derived from non-animal sources and are highly compatible with the body. When the gel is injected, it acts like an inflated cushion to support facial structures and tissues that may have lost volume or elasticity with normal aging. 

Hyaluronic acid also brings water to the surface of the skin to keep it looking fresh and supple. The gel is injected into the skin through a fine-gauge needle at the site of unwanted lines and wrinkles. While dermal fillers are generally safe, dermal filler treatments should be performed by a professional to avoid complications and serious side effects at the injection site.

Hyaluronic Acid Fillers

Hyaluronic acid fillers are temporary dermal fillers that restore skin moisture and diminish signs of aging. It’s main ingredient, hyaluronic acid (HA) is a primary component of the skin and is responsible for that plump and hydrated look. Benefits of HA fillers include anti-aging, moisturizing, anti-wrinkle, restore skin elasticity, and treat eczema and redness.  HA fillers are safe and allergic reactions are rare with this type of filler because hyaluronic acid is naturally produced by the skin. 

Hyaluronic acid fillers can last up to 18-24 months or longer. Like any cosmetic procedure, there is no guarantee of complete satisfaction, or that wrinkles and folds will disappear completely. Additional treatments may be required to achieve desired results, and visible outcomes will vary per patient. To maintain the desired effect, we recommend follow up treatments before the effects of the last treatment wear off.


Sculptra is an injectable dermal filler that has been on the market since 1999. In 2014, the FDA approved Sculptra Aesthetic for treating facial wrinkles and folds on the face to give a more youthful appearance. Sculptra works by stimulating collagen production, the protein that creates a smooth, radiant skin and youthful look. The main ingredient in Sculptra injections is poly-L-lactic acid (PLLA), a biocompatible synthetic substance that acts as collagen stimulator. Sculptra treatments can be used to treat deep lines, creases, and folds and can be used to restore facial volume loss due to aging or illness.
