The RHA collection of hyaluronic acid fillers is the first family of dermal fillers with FDA-approval to treat dynamic wrinkles and nasolabial folds. RHA fillers are beautiful at rest and flawless in motion—they restore facial smoothness by filling out your wrinkles, creases, and nasolabial folds without restricting expressions, emotions, or facial movements.

RHA filler treatments performed at Kotis address all your dynamic and static wrinkles while allowing you to smile with confidence.

How RHA Fillers Work

RHA (Resilient Hyaluronic Acid) is a collection of dermal fillers made of highly-resilient hyaluronic acid, a naturally-occurring and biocompatible component that enhances facial volume and fills out the wrinkles.

Hyaluronic acid has the unique capacity to hold 1,000x its own weight in water, making your skin appear dewy, supple, and voluminous. Youthful skin is often rich in hyaluronic acid; your body’s ability to produce and retain HA decreases with age, leading to dry, wrinkled, and hollowed skin.

RHA fillers restore your hyaluronic acid reserves, making your skin seem smoother and younger.

The RHA Difference

RHA stands apart from all other hyaluronic acid-based dermal fillers. It’s the only collection of dermal fillers with FDA-approval to treat dynamic wrinkles and nasolabial folds, i.e., the wrinkles formed due to the overuse of facial muscles.

Traditional dermal fillers can’t treat dynamic wrinkles because their hyaluronic acid components are modified to increase their longevity. In most cases, natural hyaluronic acid is almost immediately metabolized by your body, making it an insufficient treatment for wrinkles. As such, most dermal fillers modify the hyaluronic acid to increase its longevity, which, in turn, prevents it from treating dynamic wrinkles effectively.

RHA fillers are made with a gentle manufacturing process that preserves the HA’s natural structures, making them mimic the natural HA in your skin. As such, RHA fillers can enhance your facial volume and fill up the dynamic wrinkles without making you look “frozen.” You can smile, laugh, and emote comfortably without betraying signs of cosmetic work. That’s the RHA difference.

RHA Treatment Options

  • RHA 2: Injected into the mid-to-deep dermis to treat moderate facial wrinkles in adults over 22 years of age.
  • RHA 3: Injected into the mid-to-deep dermis to treat moderate to severe wrinkles and nasolabial folds in adults over 22 years of age.
  • RHA 4: Injected into the deep dermis to treat severe nasolabial folds and wrinkles in adults over 22 years of age.

The Procedure

RHA fillers are ideal for adults over 22 years of age with mild to severe fine lines, dynamic wrinkles, and nasolabial folds. Your RHA filler treatment starts with a personal consultation with Dr. Kotis. He carefully examines your facial skin and fine lines, reviews your medical history, and discusses your cosmetic goals. Based on his analysis, he recommends the ideal RHA formulation and treatment plan for your individual needs.

RHA treatment is fairly simple. The treatment areas on your face will be cleansed with an antiseptic solution, and the specific injection points will be marked. The clinician might apply topical anesthesia to the treatment spots to ensure a comfortable experience. Finally, your provider will deliver the ideal dosage of RHA fillers into the strategically-chosen locations to fill up your wrinkles. The treatment should conclude within a few minutes.

You might experience mild swelling, redness, and discomfort, but the side-effects will dissipate within a few hours. You won’t have any long-term side-effects or complications, and you can resume your daily activities immediately.


RHA fillers produce immediate results — you’ll notice an instant improvement in the dynamic areas of your face. However, the results will continue improving over several hours or days as the side-effects dissipate. Clinical trials have shown that RHA fillers last for up to 15 months.
