Frequently Asked Questions About Plumping Lips and Lifting the Corners of the Mouth

Having hyaluronic acid injected into your lips doesn’t necessarily mean they’ll end up looking like a duck’s. If too much is injected or if it’s concentrated in one area, your lips may end up looking out of proportion with the rest of your face. At YAYOI CLINIC, we assess the natural shape of your lips and the overall balance of your face, then gradually adjust the injection volume and contour to meet your preferences.

Botox injections around the corners of the mouth do not necessarily make it difficult to speak. However, since the treatment affects the muscles around the mouth, you may experience some discomfort depending on the injection site and dosage. At YAYOI CLINIC, we start with a conservative dosage for first-time patients and can make fine adjustments during follow-up visits based on your condition. If you are concerned about how this might affect your speech, please let us know in advance.

The duration of hyaluronic acid injections in the lips varies depending on the product used, the amount injected, and the individual’s physiology. In the case of Juvederm Vista Volbella XC, which is used at YAYOI CLINIC, the typical duration is approximately one year to one and a half years. Since hyaluronic acid is gradually absorbed over time, you can consult with your doctor about the timing of follow-up treatments based on your desired lip shape and how the results have progressed since the initial injection.

If you want to add volume to your lips, consider hyaluronic acid; if you’re concerned about drooping corners of your mouth, consider Botox for the corners of the mouth. Hyaluronic acid helps add volume and refine the contours, while Botox for the corners of the mouth works to relax the muscles that pull the corners down. At YAYOI CLINIC, we assess the strength of the muscles around your mouth, any asymmetry, and the overall balance of your face to recommend the treatment that best addresses your concerns.

You may feel some pain when the needle is inserted during lip hyaluronic acid injections. At YAYOI CLINIC, we take measures to minimize discomfort by cooling the injection site, using a vibrating pen, and applying anesthetic tape as needed. The “Juvederm Vista Volbella XC” we use is also a formulation that contains an anesthetic agent. If you are concerned about pain, please let us know before the procedure.

Swelling and bruising may occur after lip hyaluronic acid injections, and these symptoms generally subside within about 3 days to 1 week. The results typically settle into the lips within 2 weeks. At YAYOI CLINIC, we will check your condition after the procedure and provide guidance on precautions to take in your daily life. Since recovery times vary from person to person, please consult with us in advance if you have any important plans.

After receiving hyaluronic acid injections into your lips, please gently moisturize your lips and avoid pressing or massaging the injection sites too hard. You should also refrain from drinking alcohol, engaging in strenuous exercise, or taking long baths on the day of the procedure. You may apply makeup and wash your face starting on the day of the procedure, but avoid rubbing your lips too hard. If you experience swelling or pain, please consult your doctor.

You cannot receive Botox injections for the corners of the mouth while pregnant. At YAYOI CLINIC, we do not provide treatments to patients who are pregnant or breastfeeding. If there is a possibility that you are pregnant, you must confirm this with us in advance. When considering treatment, please inform us during your consultation if you might be pregnant or are currently breastfeeding.

The effects of Botox injections around the corners of the mouth generally begin to appear about 2 to 3 days after the procedure and are said to peak around 14 days later. The timing of these changes varies from person to person, so you may not notice a difference immediately after the procedure. At YAYOI CLINIC, we will assess the results after the injections and may recommend a follow-up visit or additional injections if necessary.

At YAYOI CLINIC, the estimated cost for lip hyaluronic acid injections is 101,800 yen (tax included), which includes 79,800 yen for one vial of Volbella and a 22,000 yen procedure fee. Since the total cost may vary depending on the injection volume and whether additional procedures are required, please discuss your desired lip shape with the doctor before confirming the cost.
