About Fillers

Facial bones diminish in size and shape with age, reducing facial definition and leaving space for the skin to stretch and wrinkle. (1) With fillers, the added volume causes the skin to stretch tighter around it. This reduces wrinkles and fades fine lines by making them more shallow. 

At Allegro MedSpa, most of our fillers contain hyaluronic acid. This is a substance that occurs naturally in the skin, allowing it to dissolve several months up to two years after injection. Unlike cosmetic surgery and other cosmetic procedures, you need not worry about making permanent changes to your appearance.

At Allegro MedSpa, we offer several types of fillers.

The Revance RHA Collection

The Revance RHA dermal filler collection is the latest advancement in hyaluronic acid (HA) filler science. Designed to adapt to facial movement, the RHA collection is resilient and dynamic by design. For this reason, Revance’s RHA fillers are the first and only FDA-approved fillers for the correction of dynamic wrinkles, or those wrinkles that appear when forming facial expressions (rather than static wrinkles, which are etched into the skin). They also have a longer-lasting effect than most other fillers. We can use the RHA filler collection in fine, moderate, and deep wrinkles, including in the nasolabial folds. The makers of RHA, Revance, recently introduced a new neuromodulator called Daxxify™ (Daxibotulinumtoxin A).


From treating lines and wrinkles to giving you lips that are full and plump, Juvéderm treatments at Allegro MedSpa of Santa Rosa provide wonderful results that are natural-looking. Juvéderm treatments can be used alone, in combination, or with other nonsurgical treatments to meet your needs and cosmetic goals. Juvéderm fillers are made with synthetic hyaluronic acid (HA) that increases your natural supply of HA and collagen for supple, healthy skin.

Juvéderm Voluma

Part of the top-selling Juvéderm family of injectable wrinkle fillers, Voluma is specially made to add contour and lift to the cheeks for a natural and more youthful appearance.

At our office in Santa Rosa, California, our experienced team performs injections of Voluma to address sunken cheeks that are flat and hollow because of weight loss, genetics, or age. With results that last up to two years, Voluma by Juvéderm is an injectable wrinkle filler that uses hyaluronic acid to help your skin look smoother and feel softer.

Other Juvéderm Fillers

  • Juvéderm XC and Vollure fill moderate to severe wrinkles and lines on the face, like parentheses lines and other wrinkles around the mouth and nose. The results usually last for about one year.
  • Juvéderm Ultra XC and Volbella adds shape to the upper lip, lower lip, or both while correcting the appearance of fine, vertical lines on the lips. The results usually can be seen for up to one year.
  • Juvéderm Voluma augments the contour of the cheeks to treat volume loss in the mid-face.


Restylane is a revolutionary dermal filler that offers a non-surgical solution to facial rejuvenation and the reduction of wrinkles. Like Juvéderm, this innovative treatment utilizes hyaluronic acid, a natural substance found in our bodies, to restore volume and enhance the appearance of the face.

  • Restylane fills in facial wrinkles and folds.
  • Restylane Defyne corrects moderate to deep smile and laugh lines.
  • Restylane Lyft adds volume and lift in the cheeks.
  • Restylane Refyne fills in fine-to-moderate smile and laugh lines.
  • Restylane Silk builds volume in the lips and smoothes vertical lip lines.
  • Restylane Kysse enhances the fullness, texture, and color of the lips while maintaining a full range of expressions.

Benefits of Fillers

Fillers are a straightforward, versatile tool for rejuvenating your appearance. They can be injected into the lips, cheeks, temples, jawline, nasolabial folds and the perioral area around the mouth. (2) A typical dermal filler treatment will address one or more of these areas, depending on the cosmetic goals of the patient. This allows for the optimization of treatment results in the pursuit of facial rejuvenation.

Fillers can reduce the visible effects of aging in a simple, minimally-invasive procedure. They can also refine the beauty of your face by reshaping it with added volume. With little commitment required, no downtime required, and a simple treatment process, they are a great way to refine your face.

Who is a Candidate for Fillers?

An ideal candidate for fillers will be curious about their face’s beauty potential. If you’re wondering how much better you could look with an in-office cosmetic treatment, but you don’t like the thought of a surgical procedure, fillers could be right for you.

Fillers are best for patients who are relatively healthy and do not smoke. While there are rarely complications or side effects from this treatment, it is best that you are capable of recovering and healing quickly.

You should only receive fillers if you have a realistic outlook about what they can do for you.

One other indication for fillers is what has become known as “Ozempic face.” This is a condition that can result from the rapid weight loss that can occur from semaglutide or tirzepatide, two of the GLP-1 medications used in the treatment of diabetes as well as an adjunct for weight loss. The relatively rapid weight loss associated with semaglutide and tirzepatide can lead to a deflation of the soft tissues of the face, giving an aged look to the face. Dermal fillers and facial fat transfers can help restore volume to the face, mitigating the effects of “Ozempic face.”

Personal Consultation

At your personal consultation, we will assess your medical history and your current health to see if fillers are right for you. We will compare the condition of your face with the goals you have in mind. With this information we will design a treatment plan. Our expert injectors will know just what to do to bring your face to a new level of beauty.

At Allegro MedSpa, we strive to provide first-class patient care, and we care about your beauty as much as you do! To schedule your personal consultation in Santa Rosa, call (707) 537-2111 or visit our contact page.


We will give you personalized instructions to follow before your first appointment. These may include a specific skin care routine to conduct before your session.

Generally, we recommend not smoking or drinking alcohol for 24 hours before the procedure, as these substances can lower your ability to heal and recover.

Fillers Procedure

Your dermal filler procedure will be incredibly simple, just sit back and receive your treatment from one of our expert injectors! You may request numbing cream to reduce discomfort if you do dislike the feeling of injections. Your procedure will involve a specific type of dermal filler that you will have chosen with our guidance beforehand.

Recovery & Results

You can resume everyday activities immediately after your appointment. Some redness, swelling or bruising may occur around your injection points. These symptoms should go away after a few hours. If you experience bruising around your injection points, this can be easily covered up with makeup. We recommend that you avoid strenuous activity for 24 hours after your treatment. You should sleep on your back with your face pointing upwards during the first night after your treatment.

After you receive your fillers, you may notice some immediate changes in your appearance. The full effects of the procedure will be visible after one or two weeks. The cosmetic results of dermal filler injections can last for six months to up to two years, depending on the formulation and your metabolism.

Corresponding & Complementary Procedures

At Allegro Medspa, we offer alternative procedures that can work in combination with fillers or achieve similar results on their own.


Botox is an injection procedure that uses botulinum to smooth wrinkles and provide a more youthful appearance. Injection of botulinum acts as a neuromodulator of the face muscles. It causes facial muscles and the skin covering them to relax. This has the effect of reducing wrinkles by stopping the contraction of your facial muscles. Botox is an effective alternative to fillers if you want to get rid of your wrinkles and look younger.

Chemical Peel

Chemical Peels can help to reduce the appearance of skin flaws, such as fine lines, wrinkles, hyperpigmentation, and more. This treatment works by removing your outermost layer of skin. During recovery your skin will naturally heal itself, causing natural rejuvenation. Chemical peels will make your skin look smoother and glow brighter. Used in combination with your fillers, your face can become even more fresh and fair.
