What is RHA®?

RHA® stands for resilient hyaluronic acid. Developed in Switzerland by TEOXANE, it is manufactured through a gentle process called ‘Preserved Network Technology’ and made with few chemical modifications – helping to preserve the natural structure of the hyaluronic acid, allowing it to closely mimic the natural substance found in our skin.

As we age, we lose some of our natural HA, causing the skin to lose structure and volume, which creates wrinkles and folds. RHA® brings vitality and tone back to the skin, with natural results.

How does RHA® work?

RHA® is designed to move with the face, targeting dynamic wrinkles and folds – the areas of the face that move repetitively. Its unique combination of stretch and dynamic strength makes it both resilient and flexible to cope with the demands of our moving faces.

The RHA® collection includes three formulations, used independently or in conjunction with each other to target specific layers of the dermis to reduce wrinkles and folds ranging from moderate to severe.

  • RHA® 2 is injected into the mid-to-deep dermis for moderate wrinkles and folds.
  • RHA® 3 is injected into the mid-to-deep dermis for moderate-to-severe wrinkles and folds.
  • RHA® 4 is injected into the deep dermis to superficial subcutaneous tissue, to treat moderate-to-severe wrinkles and folds.

What is RHA® used for?

RHA® is used in the areas where dynamic lines and wrinkles are created – such as around the eyes and mouth where the face moves in a repetitive manner. Examples of areas for treatment include:

  • Around the eyes and between the eyebrows
  • Fine lines or ‘smile lines’ around the mouth
  • Nasolabial folds
  • The jawline

Prior to your treatment, your doctor will conduct a thorough assessment of your skin, and determine which of the RHA® collection is to be used, and where.

Are there any special precautions to take with RHA®?

At your consultation and as part of your skin assessment and personalized treatment plan, your doctor will determine which treatments are appropriate for you, considering your age, lifestyle, skin condition, and medical history. As a result of certain medical conditions, some patients may not be able to undertake treatments with RHA® or other fillers. Always consult with your dermatologist prior to any injectable filler treatment – you may be asked to refrain from taking certain medications for a period of time prior to treatment in order to minimize the risk of bruising.

How is the treatment done?

To ease any discomfort, a topical anesthetic may be applied 30 minutes prior to your treatment. Fine needles are used for a series of precise injections, and ice may also be applied during treatment to reduce any swelling. Depending on the size and location of the treatment area, the injections take 15 to 30 minutes to perform.

What can I expect from an RHA® treatment?

After your appointment, you will see results straight away. You may experience some puffiness or fullness, or slight bruising, which disappears quickly – usually within a day. You will be able to wear makeup and resume taking any medication.

RHA® has proven clinical effectiveness and duration of up to 15 months, though individual results may vary. You may require supplemental treatments for the ongoing correction of some wrinkles and folds – your personalized treatment plan will outline which treatments to take, and how frequently.
