Our office carries the full RHA® collection. The RHA® fillers are made of hyaluronic acid (HA) and are designed to mimic the structure of the natural HA found in your skin. Fillers have on-label approved areas, but in the hands of a skilled injector can be used elsewhere off-label. Each filler is best suited for a specific area, concern and facial anatomy, which is where experience and expertise become important.
Redensity is the newest filler from the RHA Collection. Dr. Cox was thrilled to be one of the first physicians in the U.S. to treat with this product. Redensity is the first and only FDA approved filler for superficial dermis and dermis injection for moderate to severe dynamic perioral rhytids. In short, this filler works beautifully for superficial line filling around the mouth. An expert in facial anatomy, Dr. Cox may use Redensity in other areas off-label.
RHA®2 is indicated for use in the mid-to-deep dermis for the correction of moderate to severe dynamic facial wrinkles and folds. RHA®2 is one of Dr. Cox’s go-to fillers for superficial line filling and around the perioral area because of its ability to blend seamlessly with a patient’s natural tissue.
RHA3 holds the same indication as RHA®2, for use in the mid-to-deep dermis for the correction of moderate to severe dynamic facial wrinkles and folds. RHA®3 has more strength than RHA®2 and is often used in older patients who need more support in the lower face.
RHA®3 is indicated for injection into the deep dermis to superficial subcutaneous tissue for the correction of moderate to severe dynamic facial wrinkles and folds. RHA®4 is the strongest of the RHA® fillers and can provide natural projection and contour. This is commonly used in areas such as the midface, chin, and jawline.
Each RHA® filler has an excellent safety profile and is FDA approved. Like any surgical or non-surgical procedure, there are risks associated with treatment. As an international teacher and trainer of other physicians in facial anatomy and injection techniques, Dr. Cox stresses the importance of finding an experienced physician who understands the finer points of injectable treatment.
Downtime from RHA® fillers is minimal. The most common side effects of dermal fillers are bruising and swelling at the injection site, which typically resolves quickly. Dr. Cox will discuss in your consultation ways to minimize bruising and swelling.
Results and duration from RHA® fillers vary based on the quantity, placement, and treatment area. The RHA® fillers have an FDA approval of 15 months, although Dr. Cox often recommends patients receive filler treatments twice yearly to maintain optimal results.
Dr. Cox, Dr. Ishii and Dr. Kamrani perform RHA filler treatments in our office. Dr. Cox has performed clinical trials for most fillers on the market, and believes a physician injector with thorough understanding of facial anatomy and the nuances of various products is necessary to provide the best results.

The best! I’ve been going to Aesthetic Solutions for over 10 years and have been extremely happy with Dr. Cox’s professionalism, expertise, and personalized approach to aesthetic dermatology. Her team of highly trained and knowledgeable nurses, aestheticians and care coordinators are wonderful. If you want to age gracefully, go see Dr. Cox! – Jennifer N.
Dr. Cox and her team are second to none! Her knowledge and expertise in the field of aesthetics is readily apparent as soon as you meet her, and the team couldn’t be better. It is easy to feel comfortable during your procedure when you’re in the hands of a renowned expert, and her results speak for themselves. I am very pleased with the procedures I’ve had at Aesthetic Solutions and recommend that anyone in the triangle area (or state for that matter) go Dr. Cox for any aesthetic related wants or needs! – Megan S.
Dr Cox and her whole team were wonderful and the office is amazing. During my consultation with Dr Cox she asked me what areas on my face I wanted to improve. The results were amazing and I could not be happier. I highly recommend Dr Cox. – N.A.
Dr Cox is the best aesthetic dermatologist I have ever found. Moving from LA and the large pool of specialists has made it difficult to find A+ specialty care, but Dr Cox is excellent. Her assistant Jamie is great and her entire staff are a cut above with all treatments and care. Look no further for being in the best hands for skin care and aesthetic treatments! – Barbara J.
Awesome visit today! I really needed a pick me up from that “tired look” and Dr. Cox administered the perfect remedy! Her recommendations have always surpassed expectations and I have always felt confident in her hands. Also wanted to give a big shout out to Jamie, who offered perfect distractions (I am not brave when it comes to needles). She was very knowledgeable about the different procedures as well, which was much appreciated. Dr. Cox and her team know exactly what to do to help. The injections were a breeze to get through and well worth it! I wish I had made the appointment sooner! From reception on up, they the make a great team! I highly recommend! – Sian D.
