RHA fillers are a popular dermal filler option to enhance appearance and reduce aging signs. They mimic natural hyaluronic acid and adapt to facial movements for a natural look. RHA fillers are more flexible than traditional fillers and can last up to 15 months, providing a safe, effective, and long-lasting way to reduce aging signs. We’re proud to offer this collection at Sunder Plastic Surgery.

RHA Overview

The RHA Filler Collection could be a great choice if you're looking for a dermal filler that can give you natural-looking results. This collection of fillers is specially formulated to imitate the natural movement and flexibility of your skin, which can help reduce wrinkles and fine lines.

Each product has a different concentration of hyaluronic acid, which naturally occurs in the body and helps keep the skin hydrated and plump. The collection can adapt to your facial movements, helping to prevent them from looking stiff or unnatural.

The RHA Filler Collection comprises four different products:


RHA 2 is a lightweight, flexible dermal filler that treats fine lines and wrinkles around the mouth and eyes. These areas are particularly prone to developing wrinkles due to the constant movement and muscle activity in these regions. RHA 2 also effectively treats other areas of the face, such as the forehead and chin, where fine lines and wrinkles may be present.


RHA 3 filler is medium-strength and designed to address deeper wrinkles and folds on the face, such as those around the nose and mouth. It also adds volume to areas such as the cheeks and chin.


The RHA 4 filler is the strongest in the collection and is specifically designed to address more severe wrinkles and folds on the face, such as those around the mouth and chin. RHA 4 also adds volume to hollow areas such as the cheeks and temples.

RHA Redensity

RHA Redensity targets specific face areas, such as tear troughs, to reduce dark circles and improve skin texture. It contains a unique blend of hyaluronic acid, amino acids, vitamins, and minerals. Redensity is commonly used for under-eye rejuvenation, plumping the skin, and reducing fine lines. However, it can also improve skin texture in other face areas by stimulating collagen production.

How Does the RHA Filler Collection Work?

Hyaluronic acid (HA) is a naturally occurring substance in the body responsible for maintaining hydration and volume in the skin. The HA used in RHA fillers is cross-linked to create a more durable product that can withstand movement and provide longer-lasting results.

When injected into the skin, the HA in RHA fillers attracts and retains water, plumping up the treated area and reducing the appearance of fine lines and wrinkles. It also stimulates collagen production, which helps to improve skin elasticity and firmness over time.

RHA fillers also contain lidocaine, a local anesthetic that blocks nerve pain signals to the brain, minimizing discomfort during injection. It reduces the need for additional numbing agents, making the process quicker and more efficient. Lidocaine also minimizes post-treatment discomfort, allowing for a quick return to daily activities.

RHA Filler Benefits

RHA fillers can create subtle enhancement or a more dramatic change depending on your desired outcome. Additionally, the fillers are highly versatile and can be used in many areas of the face to enhance and rejuvenate your natural features. For example:

  • The fillers contour and sculpt the face for a more defined and youthful appearance
  • They add volume to areas that have lost elasticity or definition, such as the cheeks, chin, and jawline
  • RHA fillers smooth out any unevenness in the face, creating a more symmetrical and balanced look
  • For lip augmentation, they provide a natural-looking result that enhances the shape and volume of the lips
  • They can also smooth fine lines or wrinkles around the lips, creating a more youthful appearance
  • RHA fillers are highly effective at reducing the appearance of wrinkles and fine lines, particularly in areas such as the forehead, around the eyes, and between the eyebrows
  • They can also be used to plump up areas that have lost volume due to aging, such as the nasolabial folds

Procedure and Aftercare

First, the area to be treated is cleaned and numbed with a local anesthetic. Then, the filler is injected into the skin using a fine needle or cannula. The injection process typically takes only a few minutes and is relatively painless.

After the procedure, it is essential to follow proper aftercare instructions to ensure optimal results:

  • Avoid touching or rubbing the treated area for at least 24 hours
  • Avoid strenuous exercise, exposure to extreme temperatures, and alcohol consumption for the first 24 hours after treatment
  • To minimize swelling and bruising, you can apply a cold compress to the treated area for the first 24 hours
  • You may also take over-the-counter pain medication as needed.

With proper care and attention, most patients can expect to enjoy natural-looking and long-lasting results from their RHA filler treatment.
