RHA Fillers southern california

RHA, or Resilient Hyaluronic Acid, is the latest premium dermal filler that fights signs of aging by smoothing dynamic facial wrinkles. Designed in Switzerland, RHA fillers are now FDA-approved for the correction of moderate to severe wrinkles and folds. The RHA trio utilizes the latest filler science to help patients rejuvenate their skin and retain their natural beauty. 

Dynamic wrinkles can appear in any area of our face that moves to accommodate our facial expressions. When we purse our lips, we may see vertical lines. When we show surprise, our forehead may wrinkle. When we smile, our nasolabial folds may become more prominent. Over time, these creases become deeper, no matter how well we treat our skin!

About Hyaluronic Acid

Hyaluronic acid (HA) is a molecule that plays an important role in maintaining skin and tissue health. It’s a common ingredient in skin care products, and is also the main ingredient in many facial rejuvenation treatments. It has key biological functions, including:

  • Skin Hydration
  • Tissue Repair
  • Wound Healing
  • Cell Migration
  • Blood Vessel Formation
  • Immune Response 
  • Joint Lubrication (1)

HA Fillers

HA fillers are incredibly popular. According to recent research, in the United States alone they’re the second most frequently performed non-surgical cosmetic treatment. (2) They’re cost-effective, in-office treatments that temporarily plump and restore lost volume in the face. And, unlike Botox and other neuromodulator injectables, patients can see their results instantly! Body-compatible HA is well-suited to facial filling because it integrates well into the target tissue and provides results that last. Moreover, in the past decade, an increasing number of dermal fillers have been approved for cosmetic use in the United States. From 2014 to 2019, nine different fillers were approved for soft tissue augmentation by the FDA. (3) However, until now, no other HA filler has been purposefully designed to target dynamic wrinkles.

All About Skin

HA fillers are injected into the skin to add volume to tissue. Our skin is composed of three key layers, each with its own characteristics and functions.

  • Epidermis – The epidermis is the outermost layer of the skin. It protects the body from harmful pathogens, environmental chemicals, and damaging UV radiation. It also contributes to temperature regulation. Melanocytes, the cells responsible for skin pigmentation are also produced here.
  • Dermis – The dermis is the middle layer of the skin. Its fibrous tissues support and strengthen the skin. HA is present in large amounts, to help skin retain moisture. The dermis also contains nerve endings, sebaceous glands, and hair follicles.
  • Hypodermis – Also known as subcutaneous tissue, the hypodermis is mostly adipose (fatty) tissue and serves as padding and temperature control for the body.

Benefits of RHA Fillers

RHA fillers are the latest development in hyaluronic acid for facial rejuvenation. But what is RHA, and how does it differ from regular hyaluronic acid?

Radiant Results with RHA

One of the biggest advantages of RHA fillers is that their results can last longer. Traditional HA fillers last between 6-12 months, but RHA fillers maintain results for up to 15 months. What’s more, unlike regular HA fillers, RHA fillers can simultaneously restore lost facial volume and smooth dynamic wrinkles. 

More Natural

Using patented molecular technology, RHA fillers work in harmony with your facial expressions. RHA is an increasingly popular treatment option for patients as its results look so natural. This enables patients to display a full range of expressions without the bothersome wrinkling! 

Gently Made

RHA is made in a different way from conventional HA fillers. The gentle manufacturing process preserves the HA to help it mimic the naturally present HA in your skin. This process also makes the gel formula cleaner and purer than standard HA fillers. 

The RHA Collection at DermFx comprises three fillers; RHA 2, RHA 3, and RHA 4, each tailored for injection at varying depths into the dermis according to the aesthetic needs of the patient.

RHA Fillers at DermFx

The RHA Collection uses the latest advancements in HA science. All RHA fillers contain 0.3% lidocaine, a numbing agent that minimizes discomfort during the procedure. Patients have the choice of three different gel configurations; RHA 2, RHA 3, and RHA 4.

The RHA Collection

RHA ® 2 RHA 2 is a resilient, elastic filler injected into the mid-to-deep dermis. It can correct moderate to severe facial wrinkles and folds and is best used to correct glabellar lines (between the eyebrows) and forehead lines. It can also be used to reduce the appearance of nasolabial folds. FDA data confirms its effectiveness. On the Global Aesthetic Improvement (GAI) scale, almost 85% of study subjects reported their nasolabial folds were improved or very much improved. (4)

RHA ® 3 – RHA 3 is a resilient, thicker filler formula for moderate to severe dynamic wrinkles. Like RHA 2, it is injected into the mid-to-deep dermis. It can address nasolabial folds, marionette lines, and lower face wrinkles. Additionally, it can be used to augment and plump the lips. With RHA 3, patients can achieve natural results immediately. 

RHA ® 4 Deep skin filling and cheek augmentation with RHA 4 can reshape the face to the desired aesthetic. This formulation can create or restore volume in facial contour, particularly the cheeks. It can also correct tear troughs, and fill deep wrinkles in thick facial skin. Unlike RHA 2 and RHA 3, RHA 4 is injected deeper, ideally into the deep dermis to superficial subcutaneous tissue.

Candidates for RHA Fillers

The RHA Collection is FDA-approved for use in adults over 21 years of age. RHA fillers are a fantastic alternative to Botox for smoothing dynamic wrinkles and folds, and can achieve more natural facial volume results than other non-RHA fillers. With an RHA procedure, you effectively get two treatments in one! RHA fillers are not recommended if you:

  • Have a history of multiple severe allergies or severe allergic reactions
  • Are allergic to lidocaine (numbing ingredient)
  • Are allergic to gram-positive bacterial proteins; 
  • Have a bleeding disorder

Additionally, please inform DermFx if you:

  • Are pregnant or breastfeeding
  • Have a history of excessive scarring (keloid formation etc.)
  • Are taking immunosuppressive medication(s)

  • Plan to get a laser treatment or a chemical peel

Are RHA fillers the same as HA fillers?

Do RHA fillers last longer?

In many individuals, RHA fillers last longer. The average longevity of results from traditional HA fillers is 6-12 months. With RHA fillers, results can last up to 15 months.

What happens if I don’t like my RHA filler results?

Don’t worry! If it’s not the look you expected, like regular HA fillers, RHA fillers can be dissolved with hyaluronidase.

Which companies make RHA fillers?

RHA fillers were first developed in Switzerland by hyaluronic acid specialists Teoxane.
