What is RHA filler?

Resilient hyaluronic acid (RHA) fillers are FDA-approved dermal fillers designed to treat dynamic folds and wrinkles by adapting to facial movements for a natural look. The hyaluronic acid is infused with select chemicals in a controlled manufacturing process.


Since RHA is almost the same as natural hyaluronic acid, it smoothly adapts to the tissue, resulting in a softer face-lift. It also allows maximum flexibility. 


Types of RHA dermal fillers


There are three types of RHA dermal fillers: RHA 2, RHA 3, and RHA 4. 


  • RHA 2 and RHA 3: Used to correct mild to severe folds and wrinkles. 
  • RHA 4: A deep dermis injectable for superficial subcutaneous tissue that helps correct severe facial wrinkles and folds.

How to choose an RHA dermal filler?

If you are looking to plump your lips or smooth perioral lines, RHA 2 is the best filler. You may also use it to diminish the radial cheek lines and smooth the skin surface when injected into the higher dermis levels.


If you want to correct the commissures and nasolabial folds, your doctor can administer an RHA 3 dermal injection. RHA 4 is the ideal filler for deep lines in the jawline and lower face and deeper nasolabial folds. It may also help in contouring the cheeks.


During a consultation, one of our cosmetic dermatology providers at Sanova Dermatology will examine your face and learn more about your goals before determining which RHA dermal filler is best for you.

Hyaluronic acid is a clear, gel-like substance that our bodies produce naturally. The largest quantities are under the skin, in the connective tissues, and the eyes. The primary function of hyaluronic acid is to retain water to keep the tissues plump, moist, and lubricated.

The levels of hyaluronic acid in your body decrease over the years, contributing to the physical signs of aging. HA injections reverse these changes by replenishing hyaluronic acid beneath your skin.

Most patients find the injections highly tolerable, but lidocaine (a topical anasthetic) can be used to reduce discomfort.

Safety should come first when considering any medical procedure. Improper administration of dermal filler can cause bruising, infection, pain, discoloration, lumps, swelling, or exaggerated results.

The best way to ensure your safety is by visiting a board-certified surgeon or dermatologist for your dermal filler injections. Certification proves that the doctor completed the proper training to administer treatment.

They renew your appearance by softening facial creases and wrinkles, enhancing shallow contours, and augmenting the lips.

The results last six to 12 or more months as the skin gradually absorbs HA molecules.

Hyaluronic acid in skincare products breaks down rapidly. The body can metabolize it in about 48 hours. To prevent quick degeneration of hyaluronic acid in regular dermal fillers, manufacturers cross-link HA chains with suspended chemical protein chains.

A high-grade filler like RHA requires fewer chemical proteins, minimal modifications, and specialized manufacturing processes. The resultant product highly resembles the naturally occurring hyaluronic acid in our bodies.
