In the world of injectables, model names like Juvéderm and Restylane have change into synonymous with hyaluronic fillers identified to clean, plump and reshape areas the place there’s a quantity deficit. Now, a brand new household of fillers by Revance Theraputics known as RHA 2, RHA 3 and RHA 4 have entered docs’ workplaces stateside, and whereas their debut right here makes them new to us, they’ve been accessible in Europe for greater than 5 years.
To learn how these fillers stack up to what’s already available on the market, we spoke with Beverly Hills, CA dermatologist Ava Shamban, MD, who additionally served as an investigator for the RHA 2, 3 and 4 scientific trials.
NewBeauty: Which RHA filler work bests for various areas of the face?
Dr. Shamban: The essential distinction between every filler is the quantity of crosslinking between them. RHA 2 is greatest for perioral traces and to increase the lips. It will also be used for the radial cheek traces and in increased ranges of the dermis for a extra floor stage smoothing. RHA 3 can be utilized for nasolabial folds and the commissures, or the corners of the mouth. RHA 4 is most applicable for deeper nasolabial folds and for deeper traces within the decrease face and jawline. It’s additionally been used off-label within the midface to contour the cheeks.
NB: The phrase “movement” comes up when describing how these fillers carry out. How does motion come into play when injecting dynamic areas of the face?
Dr. Shamban: Yes, the motion element is vital with these fillers. The optimum enchancment with filler is when the face seems to be equally pretty much as good at relaxation as when in movement. These fillers combine very nicely into the tissue, which suggests they are going to be undetectable and supply what I name a “softer” end result.
Because RHA is most comparable to the native hyaluronic acid current in our pores and skin and adapts so nicely to our tissue, it permits for best flexibility. We are subsequently ready to ship an distinctive end result for sufferers at each angle all through all the size of motion of their most dynamic facial areas.
NB: Can you clarify what crosslinking is and the precise approach the RHA fillers are crosslinked that make them distinctive?
Dr. Shamban: Free hyaluronic acid current in skincare, in addition to our native HA, breaks down quickly and is metabolized in about 48 hours. To stop this incidence in dermal fillers, these HA chains are crosslinked with chemical proteins that are suspended. The fewer chemical proteins and fewer modifications and extra processes required within the manufacturing course of yield a purer and finally cleaner product.
The distinction between RHA and first-generation hyaluronic dermal fillers is the less chemical modifications and crosslinking in longer chains of HA. Therefore, the RHA product most carefully resembles native product in our physique for each flexibility in utilization, pure outcomes and longevity. This is what makes them undetectable no matter facial actions and as I at all times say—we solely need to see outcomes, not the product.
