Administering Rha2 & Rha4

RHA2 & RHA4 is a safe and effective cosmetic treatment when administered by a qualified professional like Dr. Khoobehi.  The filler is designed to mimic the natural hyaluronic acid found in the body, allowing for a more natural-looking and long lasting results.  The treatment involves injecting RHA2 & RHA4 into the targeted areas using a very fine needle. .  If you are worried about pain, we can put a topical numbing gel on the area before the injection. You will feel minor pain, but keep in mind that the medication is blended with lidocaine as well.

What To Expect

RHA2 & RHA4 is gel substance that is administered via needle at a 15 – 30 degree angle parallel to the length of the wrinkle or fold. There is no sedation needed, although a numbing cream is usually applied first to help with any discomfort. The injection sites will be sterilized and marked with ink. Once the filler is injected, results are immediately noticeable. Dr. Khoobehi may massage the treated area, so the filler spreads evenly. Other than temporary redness, the treatment has no after effect that will prevent a patient from going back to normal routine. Patients should avoid strenuous exercise for approximately 24 hours.

Expected Cost

One full syringe of RHA2 on average costs $600.00, and RHA4 on average costs $850. The final cost of treatment will depend on how many syringes of the product were used. Some sessions may take 1-3 syringes. Dr. Khoobehi is known for his expertise and personalized approach in administering RHA2 & RHA4.  He works closely with each patient to develop a treatment plan that is tailored to their specific needs and goals, ensuring that they achieve the best possible outcome.
