RHA Filler

FAQ

• How long does RHA last?

  It depends on the area. In the FDA trials, about 8 in 10 of the patients treated for smile lines and checked at about 15 months were still improved, when those studies ended. The studies for lines around the mouth, lips and cheeks ran 12 months, and about half to two thirds of patients were still improved then.

• Should I choose RHA 2 or RHA 3 for my lips?

  Of the RHA fillers we offer, RHA 3 is the one FDA-approved for lip fullness. RHA 2 is not approved for the lips. For moderate to severe lines around the mouth, including lines above the lip, RHA Redensity is the approved choice. Your provider recommends what suits your lips at your visit. We also offer Restylane Kysse for lips.

• Is RHA 1 the same as RHA Redensity?

  In the US, yes. Teoxane called RHA Redensity "RHA 1" in its US study, and FDA records list one version of it as "RHA 1 Mepi". Outside the US, Teoxane sells TEOSYAL RHA 1 for fine lines such as those around the mouth; we have not confirmed it is the identical gel. "Redensity 1", without "RHA", is a different Teoxane product that is not FDA-approved. We book this treatment as RHA Redensity.

• How many syringes will I need?

  It depends on the area and the result you want. Your provider recommends an amount at your visit before treating. Every RHA syringe is the same price, whichever product you need.

• Can RHA be dissolved?

  Yes. RHA is a hyaluronic acid filler, so it can be dissolved with an enzyme called hyaluronidase if needed.

• What is the downtime?

  Most people go back to work and daily life right after treatment. Some swelling, bruising and tenderness are expected for a few days. For the first 24 hours, avoid strong sun, tanning lamps and extreme heat or cold such as saunas, which can add to redness and swelling, and ask your provider about exercise. Your provider gives you aftercare instructions before you leave.

• Should I book before an event?

  Book at least two to four weeks before it. Most swelling and bruising settles within two weeks, but lip treatments can take longer, and some people need a touch-up two to four weeks after the first visit.

• Who will do my treatment?

  Our nurse practitioners and physician assistants, who are trained in injection safety and placement, under the oversight of our medical director, a board-certified dermatologist.

• How is RHA different from Restylane?

  Both are hyaluronic acid fillers, so the change usually shows right away, and both can be dissolved. They are made by different companies with different gels, and each product is approved for specific areas. In the one FDA smile-line trial that compared them directly, RHA 4 and Restylane Lyft gave similar results through about 15 months. Your provider can tell you which suits your areas.
