【Vaginal Rejuvenation】What is Vaginal Hyaluronic Acid Injection Treatment? Bianca's Aesthetic Gynecology Instructor Akiko Miyamoto Explains!

Supervising Physician
Aesthetic Gynecology Specialist Akiko Miyamoto

After practicing insurance-covered medicine in general obstetrics and gynecology, including infertility treatment and perinatal care, I shifted my career to private practice and gynecological aesthetics driven by my own experience battling illness and the desire to “support women in enjoying their femininity throughout life.” Grounded in deep anatomical knowledge and technical skill, I address women's health challenges with "authentic femtech"—procedures like gynecological plastic surgery, Vaginal Rejuvenation® injections, and vaginal hyaluronic acid injections—backed by medical evidence. She is dedicated to social activities promoting sex education, HPV vaccine awareness, and improving women's quality of life. She actively contributes to medical knowledge dissemination, including authoring Chapter 7, "Vaginal Hyaluronic Acid Injections," in the specialized textbook The Fundamentals of Cosmetic Surgery: The First Book to Read When Becoming a Cosmetic Surgeon.

After childbirth or during menopause, many women begin experiencing unpleasant vaginal symptoms such as "water leaking from the vagina after bathing," "vaginal dryness causing a stinging sensation," and "a lack of closeness during intercourse."

 

For such women, a treatment known as “vaginal hyaluronic acid injections,” also called "vaginal rejuvenation," was developed. Among women with a keen interest in beauty, some may have been curious about it, wouldn't you agree?

 

Surprisingly, many people are unaware that the vagina is an area prone to discomfort due to factors like aging and childbirth, which can cause looseness and dryness. However, precisely because it's such a sensitive issue that's difficult to discuss with others, it's not uncommon for people to feel alone in their struggles, wondering, "Am I the only one dealing with this?"

 

This time, for those women, let's explain the vaginal beauty treatment that's also a hot topic at Bianca: "vaginal hyaluronic acid injections."

 

What is "vaginal hyaluronic acid injection" treatment?

 

Vaginal hyaluronic acid injections are a treatment that involves injecting hyaluronic acid into the vaginal walls to provide volume, firmness, and moisture, addressing symptoms such as vaginal laxity and dryness. Because it enhances sensitivity during sexual intercourse, it is also called "vaginal rejuvenation" and has become a hot topic on social media.

 

Here are the effects you can expect from vaginal hyaluronic acid injections.

 

・Thickening of the vaginal walls narrows the vaginal canal, improving vaginal laxity ・Enhanced vaginal tightness increases the feeling of closeness during intercourse
・The vaginal area, which had become dry with age, becomes moisturized.
・Vaginal pain caused by friction during intercourse becomes less noticeable
・If mild urinary incontinence is also present, improvement can be expected alongside vaginal symptoms (however, as this is not the standard treatment for urinary incontinence, we also recommend consulting a urologist).

 

Hyaluronic acid injections are a treatment known for minimal pain and downtime, placing less burden on the body. This holds true for vaginal injections as well, making it an accessible option even for those new to gynecological aesthetics. Furthermore, since no visible scars remain on the surface, there's no need to worry about concerns like "What if my partner sees it?"

 

Why We Recommend Early Care with Vaginal Hyaluronic Acid Injections

 

Even individuals who regularly undergo facial aesthetic treatments often neglect vaginal issues. This may be partly because the vagina is less visible and discomfort or irritation in this area can be difficult to discuss with others. However, leaving these problems untreated carries a high risk of worsening, so caution is essential.

 

Furthermore, vaginal discomfort can easily become a source of psychological stress, potentially leading to a loss of confidence as a woman and a decline in self-esteem. Some women are deeply shocked when their partner points out vaginal dryness or looseness.

 

To prevent this from happening, it's crucial to seek early care immediately if you experience any vaginal discomfort. If you're currently experiencing any vaginal changes or discomfort, please come to Bianca Clinic for a consultation.

 

BIANCA CLINIC's Unique Strength! Vaginal Hyaluronic Acid Injection Performed by an Obstetrician-Gynecologist

 

Bianca Clinic offers a variety of treatments for female genitalia, including the vagina. Vaginal hyaluronic acid injections are one such treatment, and the number of women requesting them has been gradually increasing.

 

The three main features of our vaginal hyaluronic acid injections are as follows.

 

【Performed by the world's only Medytox-certified vaginal hyaluronic acid injection specialist】

 

Injections into the delicate vaginal area require careful clinic selection. In fact, we have seen patients who developed serious infections after receiving vaginal injections at other clinics.

 

Additionally, it is crucial for physicians to accurately determine the appropriate candidates for vaginal hyaluronic acid injections. Based on examination results, some individuals may require preparatory treatments like Vaginal Rejuvenation® injections to optimize the vaginal environment beforehand. Others, such as those with conditions like rectocele, may be better suited for surgical procedures like vaginal tightening surgery. There are also cases where hyaluronic acid injections are not suitable.

 

To accurately assess these conditions, a physician's experience with vaginal procedures and expertise in pelvic floor anatomy, knowledge, and technique are essential.

 

At Bianca, Akiko Miyamoto—the first physician worldwide to receive certification as a “Hyaluronic Acid Injection Instructor” from Medytox, and also a Japan Board-Certified Obstetrician and Gynecologist—conducts consultations and procedures. If you're interested in vaginal medicine but feel a little apprehensive, we invite you to visit our clinic for a consultation.

 

【Customized Treatment Based on Your Free Vaginal Health Index Results】

 

At Bianca's Vaginal Hyaluronic Acid Injection Clinic, you can receive a complimentary Vaginal Health Index Measurement. This examination checks your vaginal environment across five key areas: vaginal mucosal thickness, vaginal moisture, vaginal pH, and more. Based on your test results, we provide customized treatments tailored to each individual patient.

 

Clinics offering detailed vaginal health examinations are not very common in Japan. Moreover, they are virtually unavailable at general cosmetic clinics.

As your first step in vaginal care, please consider booking a free consultation.

 

【The “Akko Method Vaginal Hyaluronic Acid Injection” that proposes the appropriate injection site and dosage】

 

At Bianca Clinic, we first conducted a survey asking general male participants, "What kind of vagina is ideal?" By combining these results with anatomical insights, we determine the optimal injection site and volume for each individual patient.

 

Furthermore, we measure effectiveness using internationally recognized indicators related to sexual function and urinary incontinence, and administer hyaluronic acid injections using our own proven method.
