Introduction | Lips are an unexpected cause of looking older
The lips are one of the areas of the face where age-related changes significantly impact facial appearance. As the upper lip tilts forward, the red surface visible from the front becomes thinner, and from the side, the area under the nose (philtrum) appears longer. Hyaluronic acid injections into the lips are an effective anti-aging treatment to address these changes.
In this article, Dr. Shiramizu, the chief director, clearly explains everything from the effects, design options, pain, downtime, duration, and risks of lip hyaluronic acid injections. If you want to make your lips look more defined, shorten your philtrum, or try it with just one injection, please refer to this article.

The effects of lip hyaluronic acid injections | Youthful lips and anti-aging
As we age, the upper lip tends to tilt forward. When this change occurs, the area of the red lips appears smaller when viewed from the front, and when viewed from the side, the curve of the area below the nose (philtrum) becomes more pronounced and appears longer.
By injecting hyaluronic acid into the lips to lift the red surface,Your lips will return to their youthful shape, giving you a more youthful appearance both from the front and in profile.Furthermore, because hyaluronic acid has high moisture-retaining properties, it also helps to moisturize the lips of those who are concerned about dryness.
Design types | How to insert them according to your preference
Lip hyaluronic acid injections can be customized to your desired design.
- Cupid's bow (standard method of insertion)Lift the tip of the upper lip to define the lip contour. This is the most common method.
- Lifting the corners of the mouth: Hyaluronic acid is injected into the corners of the mouth to slightly lift them.
- Volume Up (Deep Injection): Adds volume to the deeper layers of the skin, stretching it and making fine lines less noticeable.
- Make the outline sharper: Defines the blurred lip contour and tightens the overall impression of the mouth.
- Philtrum shortening effect (approach to the vermilion border)By slightly adding volume to the red lip border of the upper lip (the boundary between the skin and the lip), the lips appear to protrude forward, visually creating the effect of a shorter philtrum.
Pain, downtime, and duration
| Item | Message |
|---|---|
| pain | Because the lips are mucous membranes, they are easily sensitive to pain. A nerve block (dental anesthesia) is administered before the procedure, numbing the lips before the treatment, so there is almost no pain. The anesthesia itself may cause a slight stinging sensation. |
| Swelling/puffiness | Immediately after the procedure, the lips may appear to have about 2% more volume due to the stimulation from the needles. This will subside from the next day onward. The lips are a mucous membrane and are therefore prone to swelling. |
| No good on the day | Avoid alcohol, strenuous exercise, and salty foods on the day of the procedure, as these can increase swelling. Also, avoid keeping hot objects on your lips for extended periods. |
| Internal bleeding | If bruising occurs, it will take about two weeks for it to be absorbed. If you have an important event coming up, schedule the procedure considering the downtime. |
| duration | Use a soft formula specifically designed for the lips (such as Volbella). The recommended duration is approximately one year. |
*The perceived effects and duration of effects may vary from person to person.
Guidelines for discreet amounts and risks
