What Are the Different Types of RHA Fillers?

As we age, natural volume loss in our face can lead to wrinkles and sagging skin, making us look older than we feel. Fillers (RHA4) represents the latest advancement in the fight against aging, specifically designed to adapt to the dynamic demands of the facial movements we make every day.

If you’re considering ways to refresh your appearance without compromising the natural expressiveness of your face, RHA fillers could be the answer.

Let’s explore what RHA fillers are, including the special characteristics of RHA4, and how they can restore youthful contours to your face.

What are RHA Fillers?

RHA fillers, or Resilient Hyaluronic Acid fillers, are the newest generation of HA (Hyaluronic Acid) fillers designed for dynamic wrinkles and folds. These fillers maintain their shape and integrity under the stress of repetitive facial movements, offering more natural-looking results than traditional HA fillers.

Among them, RHA4 is particularly noted for its ability to be injected deeper into the skin, making it ideal for treating severe wrinkles and folds while maintaining a natural appearance during facial movements.

Different Types of RHA Fillers

Each type of RHA filler is designed to target specific issues and areas of the face, providing tailored treatments that enhance facial features while maintaining natural expressions.

Here’s a closer look at the range of RHA fillers available:


RHA2 is typically used for superficial wrinkles and can be applied around the delicate areas of the eyes and the vertical lip lines.

It’s designed to be less viscous, allowing for a smooth application that suits more superficial lines and wrinkles. RHA2 helps soften these early signs of aging without overfilling the area, preserving the natural movements and expressions of the face.


RHA3 is a bit thicker than RHA2 and is designed for moderate to severe dynamic wrinkles. It’s ideal for deeper nasolabial folds (the lines that run from the sides of the nose to the corners of the mouth) and can also be used to enhance the lips.

The resilient nature of the filler supports the skin in areas of frequent movement, providing a balanced aesthetic improvement.


As the thickest in the series, RHA4 is excellent for correcting severe wrinkles and folds.

It can be injected into the lower layers of the dermis and is commonly used in areas that experience significant volume loss, such as the cheeks and jawline.

RHA4 not only fills severe wrinkles but also restores volume, providing a lifting effect that significantly rejuvenates the area.

RHA Redensity

RHA Redensity is specifically formulated to enhance skin texture and luminosity. It works well for overall facial rejuvenation, improving skin quality, and increasing hydration.

This type of RHA filler is lighter and more spreadable, making it suitable for a superficial injection that enhances the skin’s natural radiance without altering facial dynamics.
