Gain a Better Understanding! The Process of Hyaluronic Acid Injections
For those considering hyaluronic acid injections at a cosmetic dermatology clinic in Naka Ward, Hiroshima City, we’ll explain the procedure process at Yayoi Clinic.
■STEP 1: Consultation
After carefully discussing any symptoms or areas of concern you may have, a doctor will conduct an examination. The doctor will assess the overall balance of your face and the condition of your skin from a professional perspective and recommend the appropriate number of injections for you. Please feel free to ask any questions or discuss any concerns you may have regarding costs, downtime, or risks.
■STEP 2: Treatment (Anesthesia and Hyaluronic Acid Injections)
Depending on your preference, we’ll use anesthetic cream or a vibrating pen to help alleviate discomfort, and then inject hyaluronic acid into the appropriate layer of the treatment area using an extremely fine needle. The treatment time varies from person to person depending on the number of injections and the specific procedure, but it typically takes about 15 to 30 minutes, making it a convenient option even for those with busy schedules.
■STEP 3: What to Do After Your Treatment and Aftercare
If you do not experience any symptoms such as redness after your hyaluronic acid injection, you may apply makeup on the same day. From the day of the procedure through the following day, please avoid activities that stimulate blood circulation—such as strenuous exercise, long baths, saunas, and excessive alcohol consumption—as these increase the risk of swelling and bruising.
In addition, to prevent the hyaluronic acid from shifting or losing its shape, care must be taken not to press hard on the injection site or subject it to any irritation.
Frequently asked questions about hyaluronic acid injections
Finally, to help those considering hyaluronic acid injections at a cosmetic dermatology clinic in Naka Ward, Hiroshima City feel confident about undergoing the procedure, we’ve answered some frequently asked questions.
How much pain will I feel during the procedure?
While the level of discomfort experienced during hyaluronic acid injections varies from person to person, you may feel a brief, prickling pain when the needle is inserted, or a sensation of pressure during the injection.
Many clinics incorporate pain-management measures such as the use of ultra-fine needles, the application of numbing cream, and cooling to ensure a comfortable procedure. Furthermore, since many hyaluronic acid products contain a numbing agent (lidocaine), pain tends to decrease as the injection progresses. If you have significant concerns about pain, be sure to discuss this during your consultation.
■ Please tell me about the duration of downtime and any associated symptoms.
While downtime after hyaluronic acid injections varies from person to person, it is generally minimal or short—typically lasting only a few days—and in most cases, patients can resume their normal daily activities immediately after the procedure.
The main symptoms that may occur during downtime and their duration are as follows.
| symptoms | Period | feature |
| Redness, swelling | 2 to 3 days (up to about a week) | It's temporary and will gradually subside. |
| internal hemorrhage | A few days to about two weeks | This condition tends to occur in areas where the skin is thin and usually resolves on its own within a few days. If it bothers you, you can cover it with makeup. |
| swelling | About 1 to 2 weeks | This is due to the moisturizing properties of hyaluronic acid, which makes it more likely to appear in areas where the skin is thin. |
| pain | About 2 to 3 days | You may feel pain after the anesthesia wears off. |
In the unlikely event that your symptoms persist for more than one month, or if you experience severe pain or unusual swelling, please contact the clinic where you received treatment immediately.
■How long do the effects last?
Depending on the type of product used and the injection site, the results typically last approximately 4 to 24 months. For the Juvederm Vista® series used at Yayoi Clinic, the duration of results is approximately 4 to 9 months for Volite XC, 12 to 18 months for Volift XC, and 18 to 24 months for Voluma XC.
