Downtime at a glance
Needle marks, mild swelling, and bruising for a few days to about a week. Usually easy to conceal with makeup or a mask (individual results vary).
Typical downtime is A few days to about 1 week as a general guide (noticeable swelling for about 1–3 days; bruising, if it occurs, for about 1–2 weeks; individual results vary), and most people feel comfortable being seen in public after Many people return the same day or the next day (if bruising appears in a visible area, allowing a few days to a week gives extra peace of mind; individual results vary). How much swelling or bruising appears varies from person to person, depending on constitution and the extent of treatment.
Recovery timeline: treatment day to final result
Needle marks, mild swelling, and, in some people, bruising may appear. Many people notice reduced volume or a slight hollow in the treated area from the same day. Follow your doctor's instructions: cool the area gently with something clean, without over-icing, and avoid rubbing it firmly. Keep any makeup light on the day of treatment and follow your doctor's guidance.
Swelling and puffiness tend to peak around this time. If bruising has appeared, its color may deepen. Many people are able to go out and work as usual as long as the marks can be covered with concealer or foundation. The course varies from person to person.
Swelling often begins to settle around this time. Bruises may start to change in color from purple to yellow. The effect of the dissolving treatment (how much volume has decreased) starts to become visible.
Needle marks and swelling have mostly settled for many people by this time. Bruising also usually begins to fade. If remaining filler or asymmetry concerns you at this point, it is a good time to talk with your doctor about additional dissolving or re-injection.
If bruising occurred, it has usually faded almost completely by this time. The treated area becomes more stable, making it easier to assess the outcome.
The effect of the dissolving treatment settles and the area becomes stable around this time. Once the state with the original hyaluronic acid reduced can be confirmed, you can discuss re-injection or other treatments with your doctor if needed. The course and final appearance vary from person to person.

Common symptoms
| Symptom | Likelihood | When it appears | How long it lasts | Notes |
|---|---|---|---|---|
| Needle marks / small red spots | High | Immediately after | A few hours to about 1 day | Temporary red dots may appear at the injection points. In most cases they can be made less noticeable with makeup. |
| Swelling / puffiness | Medium | Immediately to the next day | About 1–3 days | The treated area may become temporarily puffy. This tends to be more likely after wide-area or repeated injections. |
| Bruising | Medium | Immediately to the next day | About 1–2 weeks | Bruising can occur if the needle touches a small blood vessel. It tends to be more common in vessel-rich areas such as the lips and around the eyes. |
| Volume loss / a sunken feeling | High | Immediately to a few days | Until the area settles | Because dissolving reduces the original hyaluronic acid, the area returns closer to its pre-injection state. This is not a side effect but the intended change of the treatment. |
| Itching, redness, or stinging | Low | Immediately to a few hours | A few hours to about 1 day | This can be a temporary reaction to the enzyme. If severe swelling, hives, or difficulty breathing develops, it may indicate an allergic reaction — seek medical care promptly. |
| Dissolving more or less than expected | Low | May become apparent after a few days | Additional treatment may be considered depending on the outcome | Because how easily filler dissolves varies with its type, amount, and how long ago it was injected, one session may not achieve the intended result and an additional session may be needed. |
When can I do what? (Daily-life restrictions)
| Activity | Typically OK from | Key point |
|---|---|---|
| Makeup | Same day to the next day | Often possible the same day once the needle marks have settled, but on the day of treatment follow your doctor's instructions and avoid rubbing the treated area firmly. |
| Face washing | Often possible from the same day (no rubbing) | Wash gently and avoid putting firm pressure on the needle-mark areas. Follow any instructions from your doctor. |
| Shower | Often possible from the same day | Avoid rubbing the treated area firmly. Follow your doctor's instructions for details. |
| Bathing (soaking in the tub) | Same day to the next day as a general guide | Increased blood flow can make swelling and bruising more noticeable. While swelling is still a concern, avoid long soaks and keep the water lukewarm. |
| Alcohol | From the next day onward as a general guide (avoid on the day of treatment) | Alcohol promotes blood flow and can make swelling and bruising more likely, so it is safest to avoid it on the day of treatment. |
| Exercise | The next day to a few days later as a general guide | Avoid strenuous exercise on the day of treatment and keep activity light until swelling and bruising settle. |
| Sauna / hot stone bathing | After the swelling subsides (a few days later as a general guide) | Heavy sweating and heat can prolong swelling and bruising, so avoid them until things settle. |
| Massage / firm pressure | Follow your doctor's instructions | Firmly massaging the treated area on your own judgment can affect the results and final appearance. Avoid touching it excessively unless instructed. |
| Re-injection (refilling with hyaluronic acid) | Usually from 2 weeks to 1 month onward as a general guide | Swelling and residual enzyme effects may remain right after dissolving, so refilling is generally done once the area has settled. Ask your doctor about the timing. |
Pain and anesthesia
The typical pain level is Mild. Topical numbing cream or cooling can often ease the discomfort, and fine needles may also be used to reduce the burden. If you are worried about pain, talk with your doctor beforehand about your options, including anesthesia methods. You may feel a brief pricking sensation at the time of injection. Thin-skinned areas such as the lips and around the eyes tend to be more sensitive. The discomfort is usually short-lived, and ongoing strong pain after the procedure is generally said to be uncommon, though how it feels varies from person to person.
Tips for a smoother recovery
- On the day of treatment, cool the area gently with something clean and avoid rubbing or pressing it firmly
- Avoid alcohol, strenuous exercise, long baths, and saunas on the day of treatment so as not to overstimulate blood flow
- Sleeping with your head slightly elevated is said to help ease facial puffiness
- Go easy on salt and alcohol, and get plenty of sleep and fluids
- If you bruise easily, choose a schedule with leeway, such as before a long weekend
- If any symptoms or aspects of your recovery concern you, consult your doctor early rather than judging on your own
Risks and side effects (the honest version)
- Allergic reaction: A reaction to the enzyme (hyaluronidase) can occur. The frequency is said to be low, but in rare cases severe reactions such as marked swelling, hives, or difficulty breathing (including anaphylaxis) may occur, requiring prompt medical attention.
- Over-dissolving, hollowing, or asymmetry: More volume than intended may be lost, or asymmetry may result.
- Incomplete dissolving / insufficient effect: Depending on the filler's type, amount, and how long ago it was injected, one session may not dissolve it fully and an additional session may be needed.
- Bruising and swelling: These are more likely in vessel-rich areas and may take time to fade.
- Infection: Said to be infrequent, but as with any injection the risk is not zero. Seek medical care if redness, pain, or warmth worsens.
- Temporary effect on the body's own components: Hyaluronidase is thought to act not only on the injected hyaluronic acid but potentially on surrounding tissue as well, and the effect and course vary from person to person.
Spacing and combining with other procedures
If you have a big occasion such as a wedding or photo shoot, completing treatment 2–4 weeks in advance leaves time for any bruising to fade. If you also plan to refill afterward, scheduling even earlier is reassuring (individual results vary). When an additional session is done to adjust remaining filler or asymmetry, the general guide is to wait about 2 weeks to 1 month for swelling and enzyme effects to settle. In urgent situations, however — such as suspected vascular compromise — an additional dose may be given the same day at the doctor's discretion. Consult your doctor about the final timing.
| Combined procedure | Timing | Wait time | Reason |
|---|---|---|---|
| Hyaluronic Acid Filler (re-injection) | Wait required | Usually about 2 weeks to 1 month | Swelling and enzyme effects may remain right after dissolving, and the outcome is hard to assess, so refilling is generally done once the area has settled. |
| Botox Injection | Wait required | A few days to 1 week as a general guide (if the areas are far apart, same-day treatment may be possible at the doctor's discretion) | Treating the same area can make swelling and results harder to assess. Same-day treatment may be considered if the areas are far apart, but scheduling a separate day after observing the course of dissolving is the safer choice. |
| HIFU / RF (heat-based device treatments) | Wait required | After swelling in the dissolved area settles | Heat-based treatments can aggravate swelling, so wait until the swelling from dissolving has settled. If you plan to refill, applying heat before the new injection is generally said to be the safer order. |
| Skin Booster (Water Glow Injection) | Wait required | A few days to 1 week as a general guide | Overlapping needle-based treatments on the face can make swelling and bruising more likely. Depending on the area and extent, spacing them out and proceeding after observing the course is reassuring. |
| Laser / Microneedling (Dermapen) | Wait required | About 1–2 weeks as a general guide | Putting stress on the skin while needle marks and swelling remain can make redness and pigmentation more likely. Wait until the area has settled before these treatments. |
Who it may suit / who should be cautious
May suit you
- Those concerned about overfilling or an unnatural shape from previously injected hyaluronic acid
- Those who want to correct asymmetry, lumps, or excess volume from hyaluronic acid filler
- Those who want to reset their current hyaluronic acid before a new treatment or re-injection
- Cases where vascular compromise is suspected after hyaluronic acid injection and the doctor judges that prompt dissolving is needed
Consider carefully
- Those who have previously had an allergic reaction to hyaluronidase (dissolving injections)
- Those with an infection or significant inflammation in the treatment area
- Areas injected with substances other than hyaluronic acid (such as fat or other fillers), as these cannot be broken down by this injection
- Those who are pregnant or breastfeeding (safety has not been established; decide carefully in consultation with a doctor)
- Those with severe allergic conditions or otherwise judged unsuitable by a doctor
