RHA® Collection of Fillers

The RHA® Collection offers new uses for dermal fillers with its natural appearance and unique abilities.

Asset 1

Thinking about dermal fillers but worried they won’t look natural? The RHA® Collection looks natural and even works on expression lines and wrinkles.

Our Collection of Fillers


What is the RHA® Collection of Fillers?

In the past, dermal fillers only treated some lines and wrinkles. The RHA® Collection of fillers can treat both static and dynamic wrinkles. As the first FDA-approved fillers for dynamic lines and wrinkles, the RHA® Collection has been in high demand, but only a select few practices have been chosen to offer it. 


The fillers in this collection can address two different types of lines and wrinkles. They have a unique long-chain hyaluronic acid formula that holds together and moves with your facial features better than any other filler. As a result, they are the only fillers FDA-approved to treat:

Static Lines

Most dermal fillers work on static lines. These include deep lines caused by loss of facial volume or skin sagging. Adding volume to these areas with a dermal filler will lift the wrinkles and make them look smoother. When your face is at rest, the fillers in the RHA® Collection look smooth and natural. 

Dynamic Lines

These lines form when underlying muscle activity pulls the skin into wrinkles and creases. Over time, this can create deep lines, especially around the eyes, on the forehead, and around the mouth. 

The RHA® Collection of fillers works on static and dynamic lines. The long chains of hyaluronic acid mimic those in your skin, so they look natural when your face is at rest. They also have enough resilience to stay in place while letting facial features move without restriction.

Am I a Good Candidate for the RHA® Collection of Fillers?

Most people make good candidates for the RHA® Collection of fillers. Their hyaluronic acid formula mimics skin’s own for a natural appearance and minimal risk of reactions. Hyaluronic acid is the most popular dermal filler material and is used safely worldwide. 

How Long Does a Typical Treatment Take?

A typical laser tattoo removal treatment takes about 15 to 45 minutes per session. You may need 4-12 treatments (spaced 4 weeks apart) for total removal, or 3-4 sessions to reach the desired fade for a cover-up.

What Results Will I See with RHA® Fillers?

The RHA® Collection has been designed to look more natural than any other dermal filler. It also treats dynamic lines and wrinkles previously out of reach for dermal fillers. This allows it to last considerably longer than typical hyaluronic acid dermal fillers. Your results can last up to 18 months or even longer. This timeline applies even when these fillers are used in the lips, where other dermal fillers usually only last about six to nine months.

Is There Any Downtime with the RHA® Collection of Fillers?

You will not have any downtime with these dermal fillers. You can return to your daily routine without restrictions. You might notice some minor swelling or bruising, but this will fade within a few days. 

  • Avoid taking aspirin, vitamin E, garlic, alcohol, Ginko Biloba, fish oil, or any blood thinners for 5 days before treatment as these can increase the risk for bruising. 
  • Avoid dental work or vaccinations 2 weeks before & after treatment.
  • You may have some redness, swelling, and bruising that can last a few days post-treatment. However, most of this is mild. Most people return to work the next day and can cover most of this with makeup.  
  • Avoid strenuous activity for 48 hours. 
  • Wait 4-6 weeks after injection for any Med Spa service on the face.
