Does Vaginal Rejuvenation Have Permanent Effects? Bianca's Aesthetic Gynecology Instructor Akiko Miyamoto Explains!

宮本 亜希子
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.

名器形成は永久に効果が続く?ビアンカの美容婦人科指導医 宮本亜希子が解説!

 

As you age, vaginal laxity and dryness become increasingly noticeable. Beyond post-bath leakage and the “gurgling” sound when air enters or exits the vagina, many women also become aware of these issues due to pain during intercourse or a lack of tightness.

 

Vaginal aesthetic treatments like vaginal hyaluronic acid injections and vaginal tightening procedures address these delicate concerns women face. Also known as "vaginal rejuvenation," these procedures are gradually gaining popularity in Japan alongside the trend of femcare.

 

However, when it comes to vaginal rejuvenation, the question on everyone's mind is probably, "Will the effects last forever?" After all, it takes courage to undergo injections or surgery in such a delicate area. Honestly, we all want it to be done in just one session, right?

 

To get straight to the point, some treatments provide long-lasting results, while others require periodic maintenance. Let's explain the duration of effectiveness for each treatment.

 

Does the effect of vaginal tightening last forever? Duration per procedure

 

This time, we will explain the lasting effects of the “vaginal rejuvenation” procedures performed at Bianca Clinic: vaginal hyaluronic acid injections and vaginal tightening surgery.

 

Vaginal Hyaluronic Acid Injection

 

Vaginal hyaluronic acid injections are a procedure that involves injecting hyaluronic acid into the vaginal walls to narrow the vaginal canal, addressing vaginal laxity, dryness, and loss of elasticity. Depending on the specific formulation used, the effects gradually diminish over a period of 9 months to 1.5 years after the procedure, returning to the original state.

 

Therefore, regular re-injections may be necessary to maintain the effects. However, the procedure involves minimal pain and virtually no downtime, making it easy to continue. The treatment time is approximately 30 to 40 minutes.

 

This treatment is ideal for those who wish to minimize disruption to their daily lives or who are too busy to find time. Furthermore, its lack of impact on future pregnancy and childbirth is also highly appreciated.

Vaginal Reduction Surgery (Vaginal Wall Reconstruction / Vaginal Opening Reconstruction)

 

Vaginal wall reconstruction is a surgical procedure that reduces the internal vaginal space by partially excising and detaching the mucous membrane lining the vaginal wall from the inside, then suturing the underlying connective tissue—such as weakened fascia—to tighten it. Vaginal opening reconstruction, on the other hand, involves incising and suturing the skin and mucous membrane at the vaginal entrance to adjust its size. Both procedures are chosen by individuals concerned about vaginal laxity or appearance due to childbirth or aging, such as those who notice internal mucous membrane visible from the outside after childbirth.

 

The effects of these vaginal tightening procedures last long-term once performed. While some may feel anxious or fearful due to the involvement of incisions made with a scalpel, the significant advantage is that multiple procedures are not required. With our surgical technique (vaginal wall reconstruction), suture removal after the procedure is also unnecessary.

 

However, vaginal tightening surgery is recommended for those who do not plan to become pregnant or give birth in the future. When considering this procedure, it is important to align your decision with your future life plans. We can also provide personalized recommendations for the procedure, so please feel free to consult with us.

 

Combine vaginal hyaluronic acid injections with vaginal exercises!

 

For those considering vaginal hyaluronic acid injections to improve vaginal laxity, we also recommend vaginal exercises. Vaginal exercises refer to training that strengthens the pelvic floor muscles. You may have heard of them under the name “Kegel exercises.”

 

You may not consciously think about your pelvic floor muscles much, but you can easily feel them when you stop urination or tighten your anus.

 

Strengthening the pelvic floor muscles increases vaginal pressure (the ability to tighten the vagina), which can help reduce vaginal laxity.

 

【Basic Vaginal Exercises】
1. Lie on your back or sit in a chair and relax.
2. Tightly squeeze your anus, vagina, and urethra (without tensing your abdomen, buttocks, or thighs).
3. Hold the position for about 5 to 10 seconds (3 seconds is fine until you get used to it).
4. Slowly relax your muscles and rest for 10 to 20 seconds.

 

Vaginal exercises are believed to be effective not only for vaginal laxity but also for dyspareunia and frequent urination. By practicing them consistently, you can aim for a tighter vagina.

 

Incidentally, even if the free vaginal health index measurement performed at Bianca indicates "low vaginal pressure (Oxford Scale) during contraction (when tightening the vagina)," this does not necessarily mean that vaginal hyaluronic acid injections are appropriate.

 

Vaginal hyaluronic acid injections aim to increase vaginal pressure when the vagina is not contracted. Vaginal exercises, on the other hand, increase vaginal pressure during contraction. Therefore, combining both methods can produce synergistic effects.

 

For vaginal rejuvenation, visit Bianca Clinic where you can receive treatment by an OB-GYN specialist!

 

The effectiveness of vaginal rejuvenation can be significantly influenced by the skill and knowledge of the performing physician. At Bianca Clinic, I personally handle all consultations and procedures.

 

Clinics where obstetricians and gynecologists with deep knowledge of vaginal anatomy and function perform vaginal rejuvenation are not that common even in Japan.

 

If you're nervous about your first visit to a cosmetic gynecology clinic, or if you want to experience real results from your treatment, we invite you to schedule a consultation at Bianca Clinic.
