As we age, our skin naturally loses subcutaneous fat, collagen, and elastin, which provide youthful volume and structure.
Blackhawk Plastic Surgery & MedSpa offers a sophisticated suite of dermal fillers designed to restore these lost contours, smooth deep lines, and lift the face without the need for surgery.
Under the expert guidance of Stephen J. Ronan, MD, FACS, our injectable treatments are never about overfilling. They are about restoring harmony, symmetry, and a refreshed version of you.

Dermal fillers are injectable, gel-like substances used to counteract the visible signs of aging by restoring volume and smoothing the skin's surface. Unlike neurotoxins (like Botox), which relax muscles, fillers physically fill the space where collagen and fat have diminished. At Blackhawk Plastic Surgery & MedSpa, we primarily use hyaluronic acid (HA) fillers, such as the Restylane family.
Because HA is a naturally occurring sugar in the human body, these treatments are highly biocompatible and provide a soft, hydrated, and incredibly natural appearance.

Restylane adds volume and fullness to the skin to correct moderate to severe facial wrinkles and folds, such as the lines from your nose to the corners of your mouth (nasolabial folds).
Restylane works immediately by adding volume to smooth away wrinkles. A clear gel formulation of hyaluronic acid, Restylane is specifically formulated to act like your body’s own hyaluronic acid.
Restylane visibly reduces moderate to severe facial wrinkles and folds for a younger-looking you.

Just like Restylane, Lyft adds volume and fullness to the skin to correct moderate to severe facial wrinkles and folds, such as the lines from your nose to the corners of your mouth (nasolabial folds). Like Restylane, Lyft is a clear gel formulation of hyaluronic acid specifically formulated to add fullness, like your body’s own hyaluronic acid.
What makes Lyft different is the average particle size and the depth of injection. On average, Lyft gel particles are larger than those in Restylane, making Lyft a good choice for wrinkles that benefit from deeper injection into the skin. In three clinical studies of 150 patients each, on average, 70% of patients maintained improvement for 6 months after a single Perlane/Lyft treatment.

Dermal fillers are remarkably versatile, addressing a wide range of age-related concerns, including:
While most commonly used to rejuvenate the face—including the cheeks, lips, and jawline—dermal fillers like Restylane Lyft are also FDA-approved to restore volume to the back of the hands, diminishing the visibility of veins and tendons for a more youthful look. Learn more about hand rejuvenation.

Ideal candidates are healthy adults looking to improve signs of aging or enhance specific facial features. Whether you are in your 30s looking for pre-juvenation or in your 60s seeking to restore lost structure, fillers offer a solution for almost every skin type. You should avoid fillers if you have an active skin infection at the injection site or a known allergy to lidocaine or hyaluronic acid products.

The primary benefit of dermal fillers is the ability to achieve a liquid facelift with immediate results and no surgical recovery.
There is virtually no downtime associated with dermal fillers. You may experience mild swelling, redness, or bruising at the injection site, which typically resolves within 24 to 48 hours. We recommend avoiding strenuous exercise, excessive heat (like saunas), and alcohol for the first 24 hours to minimize swelling. Applying a cold compress intermittently after your treatment can help ensure a smooth and comfortable recovery.

The beauty of dermal fillers lies in their instant results. The volume is added the moment the gel is injected. However, the final look is usually achieved about two weeks post-treatment once any minor swelling has completely subsided and the filler has fully integrated with your tissues.
Depending on the area treated and the specific Restylane product used, your results can last anywhere from 6 months in high-movement areas like the lips to 18 months in more static areas like the cheeks. Regular maintenance treatments can help you sustain your youthful glow indefinitely.
