What Are Vaginal Hyaluronic Acid Injections? A Clear Explanation of the Expected Effects, Benefits, and Drawbacks
After engaging in general obstetrics and gynecology practice, including infertility treatment, perinatal care, and other insured treatments, I decided to shift my career to free practice and gynecological aesthetics, with the hope of “supporting women to enjoy their life as a woman” after my own experience fighting against illness. Today, while still being involved in insured medical care as an obstetrician/gynecologist, I am facing women's health issues based on medical evidence through "real femtec" such as gynecologic plastic surgery, Vaginal Growth® injections, and vaginal hyaluronic acid injections, based on my deep anatomical knowledge and skills. We are a leading provider of gynecological services in Japan.
She is also committed to social activities related to the dissemination of sex education, HPV vaccine awareness, and the improvement of women's quality of life. He is also actively involved in educating the public about medical knowledge, such as writing Chapter 7, "Vaginal Hyaluronic Acid Injection," in his specialty book, "The Basics of Cosmetic Surgery," which is the first book he reads when he becomes a cosmetic surgeon.
Depending on the clinic, this procedure is sometimes called “vaginal hyaluronic acid injection” or “vaginal hyaluronic acid infusion.”
During consultations, it’s not uncommon for patients to tentatively confide in us about vaginal dryness, occasional urine leakage, or changes in vaginal tone.
In this article, a doctor from BIANCA CLINIC explains everything from how the treatment works to its expected effects, benefits, and points to keep in mind.
What is a vaginal hyaluronic acid injection?
Vaginal hyaluronic acid injections are a non-surgical procedure in which hyaluronic acid is injected into the vaginal walls to restore thickness and moisture within the vagina.
How Hyaluronic Acid Is Injected Into the Vaginal Wall
The procedure itself is very simple. While checking the condition of the vaginal walls, we inject the hyaluronic acid solution in small amounts.
Since the addition of hyaluronic acid physically increases the volume of the vaginal walls, you can expect changes such as a narrowing of the vaginal space and a restoration of thickness and firmness to the vaginal walls.
Since hyaluronic acid has the ability to bind moisture, we sometimes recommend it to patients who are concerned about dryness or a lack of moisture. However, the appropriate amount and injection site vary from person to person, depending on the thickness of the vaginal wall, the condition of the folds, the patient’s symptoms, and their individual preferences.
For that reason, it could be said that the post-treatment outcome is highly dependent on the doctor's technical skills and experience.
A major difference between this vaginal tightening procedure—which uses a scalpel—and others is that it does not involve an incision in the skin; however, since it involves an injection, there is still a risk of bleeding or swelling.
Determine the treatment plan after assessing the condition of the vagina
If the vaginal walls are thin or the vaginal folds are shallow, it may be more appropriate to undergo treatment to improve the condition of the vagina before receiving hyaluronic acid injections.
Some people might think, “It’s just a shot, so I can probably get it right away,” but that doesn’t necessarily mean you’ll be able to get it on the very day you decide you want it.
At Bianca Clinic, we determine a treatment plan after conducting a free “Vaginal Health Index Assessment”—which checks vaginal tone, moisture levels, and vaginal pH—along with a pelvic exam. This assessment helps you understand the condition of your vagina, so if you’re concerned, we encourage you to give it a try.

▶Detailed Information on Vaginal Hyaluronic Acid Injections
What results can be expected from vaginal hyaluronic acid injections?
Vaginal hyaluronic acid injections are intended to restore the thickness and moisture of the vaginal walls, and are expected to help alleviate concerns such as looseness, loss of tightness, and dryness.
The main changes you can expect are as follows:
- You may feel heat or pain
- Redness, swelling, and bruising may occur.
- There is a risk of burns, blisters, numbness, and other complications.
- Depending on the irradiation method, this may lead to sunken cheeks.
- The way the effects manifest and how long they last vary from person to person.
A key characteristic of hyaluronic acid injections is that they increase the thickness of the vaginal wall, which physically narrows the vaginal cavity.
If you feel that your vagina has become looser or that you no longer experience the same sense of closeness during intercourse, you can expect to see these changes. While some people notice a difference in volume immediately after the procedure, the degree to which this is felt varies from person to person.
Hyaluronic acid can also help alleviate dryness, stinging, and discomfort caused by friction during intercourse by restoring moisture to the vaginal walls. However, since these symptoms may sometimes be caused by factors other than lack of moisture, it’s important to identify the underlying cause through a medical examination.
You may also notice changes in vaginal discharge after a bath, depending on the condition of your vagina.
On the other hand, for those who are concerned only about urinary incontinence or who experience severe symptoms, examinations and treatments at a urology clinic or similar facility may be more appropriate than vaginal hyaluronic acid injections.
What are the pros and cons of vaginal hyaluronic acid injections?
While vaginal hyaluronic acid injections offer the advantage of being performed without the use of a scalpel, they also carry risks such as swelling, bruising, and infection, as well as limitations in their effectiveness.
Benefits of Vaginal Hyaluronic Acid Injections
- The procedure can be performed without using a scalpel
- Allows you to adjust the injection volume and injection site
- You may notice a change in volume immediately after the treatment.
- Local anesthesia and nitrous oxide anesthesia can be used
- The estimated treatment time is about 30 to 40 minutes.
Since no scalpel is used, there is virtually no downtime. Also, because the procedure is performed via injection, the treatment time is relatively short, and you can even take a shower on the same day—which is a nice bonus.
For those who want to minimize the impact on their daily lives as much as possible, this might be a good option.
Another appealing aspect is that, after discussing your needs during the consultation, the amount and injection sites can be fine-tuned. That said, injecting more doesn’t necessarily lead to better results.
Our approach to treatment is to carefully assess the condition of the vaginal walls and discuss what changes you hope to achieve, while working together to determine the medically necessary scope of treatment.
Disadvantages of Vaginal Hyaluronic Acid Injections
- Swelling, pain, edema, and bruising may occur.
- Bleeding or redness may occur at the injection site.
- The effects are not permanent.
- Depending on the condition of the vagina or your medical history, you may not be eligible for this procedure.
Since this treatment involves a sensitive area, many people probably want to know about the risks as well.
After the procedure, you may experience swelling, pain, bruising, or other symptoms; the severity of these symptoms and the time it takes for them to subside vary from person to person. If you experience severe pain, difficulty urinating, or persistent bleeding, please do not hesitate to contact the clinic.
In addition, we ask that individuals who are pregnant or breastfeeding, or those who suspect they may have a gynecological infection, refrain from receiving treatment. We will ask about your medical history and any medications you are taking during your consultation, and depending on the details, we may not be able to provide treatment.
Frequently Asked Questions
We answer common questions from patients regarding vaginal hyaluronic acid injections—including duration of results, downtime, the procedure process, pain management, and pre-treatment precautions.
When people hear about injections in the intimate area, many feel anxious, thinking, “That sounds painful” or “What if I experience side effects?”
In addition to the questions listed here, I’ll be happy to answer any other questions you may have during our counseling session, so please feel free to ask.
Q. Please tell me about the effects and duration of vaginal hyaluronic acid injections.
A. Many patients notice results immediately after the procedure. While the duration of the effects varies depending on the formulation and the patient’s individual constitution, it generally lasts between 9 months and 1.5 years. Since this is not a permanent treatment, we will discuss the best time for your next session during your consultation.
Q. How long is the downtime for vaginal hyaluronic acid injections?
A. After the procedure, you may experience swelling, pain, bruising, or other side effects. You may take a shower on the same day, but please refrain from taking baths, having sexual intercourse, and engaging in strenuous exercise for about one week. The speed of recovery varies from person to person.
Q. What is the procedure for vaginal hyaluronic acid injections?
A. The procedure begins with a consultation and a pelvic exam to assess the condition of the vagina and determine suitability and the appropriate injection volume. After administering a local anesthetic, hyaluronic acid is injected, and the session concludes with instructions on aftercare. The procedure typically takes about 30 to 40 minutes.
Q. Are there any ways to manage the pain associated with vaginal hyaluronic acid injections?
A. We perform the procedure using local anesthesia. The level of pain varies from person to person, and for those who are particularly anxious, we can also use nitrous oxide anesthesia in combination. If you have any concerns, please feel free to mention them during your consultation.
Q. What preparations and precautions should I take before getting vaginal hyaluronic acid injections?
A. Since it can be difficult to determine whether you are bleeding during your period, we ask that you reschedule your appointment if possible. During the consultation, we will ask about your current medications and medical history, so please bring a note or similar record with you if necessary.
