What Is the RHA Collection?

Crafted by TEOXANE Laboratories, the RHA (Resilient Hyaluronic Acid) Collection represents a cutting-edge advancement in cosmetic fillers, offering long-lasting solutions for facial lines, wrinkles, and folds. With age, facial contours may lose volume, leading to the formation of lines and wrinkles. By skillfully administering the RHA Collection, we restore volume and smooth away imperfections, delivering a non-surgical rejuvenation that enhances your natural beauty. From softening facial lines to restoring lip fullness and addressing unwanted scars, the RHA Collection provides immediate and lasting results, rejuvenating your appearance with a youthful glow.

How Does the RHA Collection Work?

RHA dermal fillers harness the power of resilient hyaluronic acid to replenish volume and restore youthful contours to your face. Following treatment, you'll notice immediate improvements, although mild swelling may occur initially, subsiding within days. Individualized treatment plans, guided by our master injectors, ensure optimal outcomes tailored to your specific needs, ensuring a refreshed and rejuvenated appearance that enhances your natural features.

Do RHA Injections Hurt?

The level of discomfort experienced during RHA injections can vary from person to person. However, RHA fillers typically contain lidocaine, a local anesthetic, which helps minimize pain during the injection process. Additionally, healthcare providers may use topical numbing creams or ice packs to further reduce discomfort. While some individuals may still feel mild discomfort or pressure during the procedure, many find RHA injections to be relatively tolerable overall.

How Do RHA Fillers Differ From Other Dermal Fillers?

RHA fillers feature longer chains of hyaluronic acid (HA) and undergo fewer chemical modifications compared to other HA fillers like Juvéderm and Restylane. With gentle processing at lower temperatures, the HA retains more of its natural structure, resulting in enhanced stability and resilience, hence the name "resilient hyaluronic acid." For you, this means that the filler mimics organic substances found in your body more closely. As a result, facial movements appear particularly natural, whether it's laughing, talking, or frowning. This quality makes RHA injections in Nashville with our team ideal for those seeking subtle, "undetectable" filler results–providing soft volume without obvious signs of treatment.
