Your skin loses its capability to adapt to your face’s movements as you age. It loses its elasticity and dynamic wrinkles develop. These are the lines that appear on your face when you squint your eyes, cry, frown, smile or make other facial expressions. Through the years of being exposed to gravity, the tissues in your face will slowly give in at some point. When this happens, you develop hollow-looking cheeks and saggy skin along the chin as the bony structure of your face is exposed.
While the aging process can’t be reversed just yet, the signs of aging can be decreased or concealed with the use of skin treatments such as dermal fillers. Dermal fillers are injectables that are injected into the skin at different depths to restore or add volume to the treatment area.
The RHA Collection is the newest collection of dermal fillers in the market and they’re the first and only FDA-approved hyaluronic acid fillers for dynamic wrinkles. This new innovation is made by Teoxane, a Swiss company whose Founder and CEO Madame Valerie Taupin also co-created Juvederm which dominated the hyaluronic filler market before RHA.
The purpose of the development of the Revance RHAs is to achieve a more natural look with the use of less synthetic ingredients to preserve the ability of the solution to mimic natural HAs in the skin better. Because of the decreased chemical modifications in RHAs unlike traditional HAs, they bond with the surrounding tissues easier and allow for a softer look on the surface while adapting to the movements of the face. This means that you don’t have to worry about unnatural bulging, distortion and uncomfortable tightness around the treated areas when making facial expressions.
RHA Collection Products
The RHA Collection consists of three products:
RHA 2 is used for treating moderate to severe dynamic wrinkles and folds when injection site is in the mid-to-deep dermis.
RHA 3 is used for areas around the mouth, nasolabial folds and commissures. 
RHA 4 is appropriate for heavier lines and folds located on the lower face and jawline. It’s used to inject into the deep dermis to reach subcutaneous tissue in the process of clearing wrinkles and folds. 
What exactly are dynamic facial wrinkles and folds?
When you were young and wrinkles would form on your face when you laughed, cried, smiled or frowned, the collagen and elastin in your skin would allow it to return to its original form. However, as you age, your skin loses its ability to adapt to the movements of your face and bounce back to its original form. When this happens, dynamic wrinkles form. Repetitive movements and loss of collagen and elastin are not the only causes of dynamic wrinkles. Other causes include: exposure to the sun, pollutants, toxins, and smoking among others.
Recovery
It is possible for the treated area to swell after being injected and if this happens, an ice pack applied on the treated area should help reduce swelling. However, avoid leaving the ice pack on the treatment area for a prolonged period of time when the anesthetic is still in effect as this may cause thermal injury.
What makes RHA Products different?
A short answer to why you should choose RHA products over traditional HAs is that they’re simply better. RHA products are made to resolve the same problems, but they are designed with less chemical modifications which helps the filler mimic natural HAs found in the skin. This innovation allows the filler to integrate into the tissues easier without unnecessary bulging or distortion.
Who shouldn’t undergo Revance RHA treatment?
You shouldn’t be injected with Revance RHAs if you have severe allergies to gram positive bacterial proteins, hypersensitivity to anesthetics such as lidocaine or bleeding disorders.
