Cosmetic Doctor uses a selection of dermal fillers to achieve the most natural, subtle look for you. Used alone or in combination with each other or with botox, dermal fillers are ideal for plumping up static wrinkles, replacing lost facial volume or softening lines in specific areas.

The aesthetic eye of the practitioner is always a vital factor in achieving the most natural result, and Dr. Fay’s understanding of the musculature underlying the face allows her to place the appropriate dermal filler for optimum effect.

The amount of time each patient gets from the fillers before needing a top-up treatment varies by person; placement of product and frequency/timing of ongoing top-ups. All these factors play a role in how long each filler lasts-from a few months to a few years.

Juvederm® Ultra and Juvederm® Ultra Plus

These dermal fillers typically last up to a year before touch-up treatments are needed. Added longevity can be achieved by asking Dr. Fay for a touch-up while some filler is still present in the face, as this usually causes a response of additional collagen production from the body.

As with other advanced dermal fillers, many patients require less product and longer treatment intervals over time.


Radiesse can last quite a long time; up to 12 months before a top-up is needed. AS with some other fillers, returning for a touch-up before 12 months may add to collagen production around the product.

In some instances, patients will notice temporarily diminished results a few months after the treatment, before the body begins to respond with its own collagen generation. Medical practitioner technique and area of placement both play roles in the speed in which Radiesse® is reabsorbed by the body.

Patients and medical practitioners have reported needing less product and longer intervals between touch up treatments over time, if patients are diligent in returning for touch ups before the product has completely dissipated from the body.

Restylane® and Perlane®

Depending on the area of treatment, results will usually last anywhere between 4 to 9 months or more before you need a touch up treatment.

Again, you may get added longevity from the product by coming back for a touch-up while the filler is still present in the body, as it will build more collagen around the dermal filler.

As with other advanced dermal fillers, many patients require less product and longer treatment intervals over time.

Dr. Fay will tailor dermal filler treatments specifically for you, and must assess you thoroughly before injecting any anti-ageing materials, as each patient is unique.
