RHA Fillers

RHA fillers are a type of hyaluronic acid (HA) based dermal filler designed to mimic the natural hyaluronic acid found within the skin. Each filler within the RHA family is formulated with a unique cross-linking technology that allows the HA molecules to move and adapt to facial expressions, providing natural-looking results with improved flexibility and durability. They offer a sophisticated approach to facial rejuvenation, providing subtle yet effective results that maintain natural facial expressions.

How Is RHA Different from Other Fillers?

What sets RHA fillers apart is their unique formulation, which allows them to adapt to the dynamic movements and expressions of the face, providing natural-looking results with improved flexibility and durability. RHA fillers are specifically engineered to withstand the stresses of facial movement, making them particularly well-suited for areas of the face that experience frequent motion, such as around the mouth and eyes. These fillers are available in various formulations to address different aesthetic concerns, including softening wrinkles, restoring volume, and enhancing facial contours.

What Areas Do RHA Fillers Treat?

  • Cheeks
  • Nasolabial folds (smile lines)
  • Marionette lines (frown lines)
  • Chin and jawline
  • Pre-jowl sulcus
  • Chin shadow
  • Temples
  • Lips
  • Peri-oral wrinkles
  • Tear troughs

The RHA Filler Collection

The RHA collection consists of different formulations of hyaluronic-acid based dermal fillers, each tailored to address specific aesthetic concerns of the face.


The most robust formulation in the collection, RHA 4 is specifically formulated to provide significant volume restoration and contouring for deep facial folds and larger areas. It is commonly used for the cheeks, chin and jawline.


RHA 3 has the firmness to address deep wrinkles and folds but enough stretch to withstand areas of the face more prone to movement. This makes it suitable for treating the nasolabial folds and marionette lines which surround the nose and mouth.


A versatile filler that is suitable for moderate lines and wrinkles, as well as for enhancing lip volume and contour. It offers a balance of flexibility and support, making it ideal for smoothing smile and frown lines, chin shadows and the pre-jowl sulcus.

RHA Redensity

The lightest formulation in the RHA collection and designed for fine lines and delicate areas of the face such as around the eyes, the temples and lips. It provides subtle yet effective correction for superficial lines, especially the hard-to-treat perioral wrinkles.

I’ve known Dr. Rothaus for quite a while – I’ve been coming to the NYC location since getting my ears pierced in elementary school and am now in my 20s working full-time in Manhattan!
