Are RHA Fillers Safe?
RHA contains lidocaine for minimal discomfort. Formulated by a Swiss company, Teoxane Laboratories, RHA received approval in Europe in 2015. A gentle patented manufacturing process uses few chemical modifications to preserve the product’s natural structure. In general, hyaluronic acids are less prone to reactions. When paired with RHA’s gentle manufacturing, an allergic reaction is very rare.
Avoid dental work (including cleaning) for three weeks before or after your filler appointment. If you are sick or taking antibiotics, you should wait until you feel well again. Additionally, if you need any immunizations, including the COVID-19 vaccine, please get them done 4 weeks before your filler appointment to avoid complications.
