Why We Use the RHA® Collection

The RHA® (Resilient Hyaluronic Acid) Collection is the first and only FDA-approved hyaluronic acid filler for dynamic facial wrinkles and folds, and it’s made for people who want natural results that hold up with expression—not a frozen or puffy look. But beyond beautiful outcomes, RHA is scientifically advanced and remarkably pure.

What Makes RHA® Different?

  1. Preserved Network Technology - RHA is produced through a gentle, proprietary manufacturing process called Preserved Network Technology. This method minimizes the need for heavy chemical modification, preserving the natural structure of hyaluronic acid. The result? A filler that integrates seamlessly into your tissue and adapts to your facial movements.
  2. Low BDDE Content - BDDE (1,4-Butanediol diglycidyl ether) is the chemical used to crosslink hyaluronic acid in dermal fillers—it’s what gives the gel structure and longevity. While necessary, too much BDDE can increase the risk of inflammation or delayed hypersensitivity reactions. RHA fillers have one of the lowest levels of free BDDE on the market, making them:
  • Gentler on your tissue
  • Less inflammatory
  • More biocompatible
  • That means fewer reactions and a cleaner long-term safety profile—a major plus for health-conscious clients and anyone prone to sensitivity.

Made in Switzerland - RHA fillers are developed by Teoxane, a Swiss pharmaceutical company known for precision, quality, and innovation in aesthetics. Europe has used these fillers safely for years before they became FDA-approved in the U.S.
