Downtime at a glance
Swelling and redness at the injection sites typically last 2–3 days, and bruising, if it occurs, about 1–2 weeks. The under-eye area is prone to swelling and puffiness, so allowing extra time before important events is reassuring.
Typical downtime is 2–3 days (swelling and redness); if bruising occurs, it often fades within about 1–2 weeks, and most people feel comfortable being seen in public after Often said to be possible from the next day (for areas where swelling shows easily, such as under the eyes, allowing 2–3 days is safer). 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
After your blood is drawn, the centrifuged PRP is injected. Swelling, redness, and needle marks tend to appear at the injection sites, and under the eyes you may notice a puffy, swollen feeling. On the day itself, avoid rubbing the treated area, and it is safest to skip alcohol, strenuous exercise, long baths, saunas, and other activities that strongly boost circulation. If you cool the area, follow your clinic's instructions.
This is when swelling and puffiness tend to be most noticeable. If bruising develops, it may appear as a purplish mark around this time. Makeup is generally considered fine from the next day as long as the needle marks have settled, and many people are said to manage desk work as usual.
Swelling and redness begin to settle around this time. In thin-skinned areas such as under the eyes, puffiness or slight fullness may continue a little longer. Bruising can be covered with makeup while you watch how it progresses.
Swelling is often barely noticeable by this point. Any bruising typically takes on a yellowish tinge and fades to a level that concealer can hide. Changes in the skin are usually not yet noticeable at this stage — from here, you wait for gradual improvement.
Downtime symptoms have generally settled for most people by this time. It is a good point to check for any remaining lumps or unevenness yourself, and to contact the medical institution where you had the procedure if anything concerns you.
Some people are said to begin noticing changes in skin firmness and texture around this time. The degree and timing of change vary widely from person to person, and one session alone may not produce a noticeable difference. If you are planning multiple sessions, discuss the timing of the next one with your doctor.
This is when changes associated with the production of collagen and other components are said to become fully apparent. It is a good time to evaluate the result and consider additional sessions or combinations with other treatments. Because the degree and duration of results vary from person to person, discuss next steps with your doctor.

Common symptoms
| Symptom | Likelihood | When it appears | How long it lasts | Notes |
|---|---|---|---|---|
| Swelling and puffiness | High | Immediately after treatment | 2–3 days | Caused by the volume of injected fluid and the needle's irritation, this tends to be more noticeable in thin-skinned areas such as under the eyes. It is generally said to settle within a few days. |
| Redness and needle marks | High | Immediately after treatment | 1–3 days | Temporary redness and small needle marks may appear at the injection points, but within a few days they can often be covered with makeup. |
| Bruising | Medium | Same day to the next day | 1–2 weeks | Bruising can occur if the needle touches a small blood vessel. It tends to appear more easily in thin-skinned areas such as under the eyes and around the mouth. |
| Dull ache or tenderness when pressed | Medium | Immediately after treatment to a few days | A few days | Tenderness or discomfort at the injection sites is generally said to ease within a few days. If strong pain persists, consult your doctor. |
| Itching or warmth | Low | Same day to a few days | A few days | These are considered temporary symptoms that accompany the tissue's repair response. If intense itching or spreading redness develops, seek medical attention promptly. |
| Lumps or unevenness | Low | A few days to a few weeks later | Several weeks or longer (depending on severity) | You may feel temporary firmness or unevenness at the injection sites. Most cases are said to smooth out over time, but if it lingers or a bump is pronounced, consult the doctor who performed the procedure. |
When can I do what? (Daily-life restrictions)
| Activity | Typically OK from | Key point |
|---|---|---|
| Makeup | From the next day | It is common to avoid makeup on the day of treatment to prevent infection through the needle marks. From the next day onward, avoid rubbing the injection points firmly. |
| Washing your face | From the same day (gently, without rubbing) | It is safer to avoid firm massage or pressure on the injection sites for a few days to a week. |
| Shower | Usually considered fine from the same day | A lukewarm shower is generally considered to be no problem. |
| Bathing (soaking in the tub) | From the next day to 2 days later as a guide | A long soak on the day of treatment boosts circulation and can make swelling and bruising more pronounced, so it is safest to avoid it. |
| Alcohol | From 2–3 days later as a guide | Increased circulation can prolong swelling and bruising, so it is common to abstain at least on the day of treatment. |
| Exercise | Light exercise from the next day / strenuous exercise from 2–3 days later as a guide | Increased blood flow can make swelling and bruising more noticeable. |
| Sauna and hot-stone baths | From about 1 week later as a guide | High heat boosts circulation and can cause swelling and bruising to flare up again, so it is safest to hold off for a while. |
| Massage or facial treatments on the treated area | From about 1–2 weeks later as a guide | Firmly kneading the injection sites can lead to swelling or unevenness, so it is common to wait until things have settled. |
| Sleeping face-down / pressure on the treated area | From 2–3 days later as a guide | If the injections were under the eyes or in the cheeks, pressure during sleep can make puffiness worse. Raising your pillow slightly is said to help swelling subside. |
| Taking fever reducers (anti-inflammatory painkillers) on your own judgment | Follow your doctor's instructions | Because PRP works through the body's natural repair response, some clinics give specific guidance on medications that strongly suppress inflammation. Be sure to tell your doctor in advance about any medications you are taking. |
Pain and anesthesia
The typical pain level is Mild. A topical numbing cream and cooling are commonly used together. If you are worried about pain, ask your doctor about anesthesia options in advance. There is the pain of the blood draw, plus a brief pricking sensation during injection and a feeling of pressure as the fluid goes in. Thin-skinned areas such as under the eyes can feel somewhat more sensitive, but many clinics use a topical numbing cream, and most people are said to find the discomfort tolerable. Sensitivity varies from person to person.
Tips for a smoother recovery
- Avoiding alcohol, strenuous exercise, long baths, saunas, and other activities that strongly boost circulation on the day of treatment and the next day tends to keep swelling and bruising from becoming pronounced.
- Sleeping with your pillow slightly raised so your head stays above your heart is said to help facial puffiness and swelling subside. This can be especially helpful when the injections were under the eyes.
- If you bruise easily, or are taking blood-thinning medications or supplements, telling your doctor in advance helps with managing the risk.
- Guidance on whether and how long to cool the area differs from clinic to clinic. Do not keep icing for long stretches on your own judgment — follow the instructions of the medical institution where you were treated.
- If you have an important event coming up, having the treatment at least 2–4 weeks beforehand allows time for swelling and bruising to settle.
Risks and side effects (the honest version)
- How results appear, their degree, and how long they last vary widely from person to person, and some people may not notice much change. Multiple sessions are often recommended, so confirm the expected number of sessions and overall cost in advance.
- Swelling, bruising, redness, pain, and itching can occur. Most cases are said to settle within a few days to about 2 weeks, but if symptoms linger, consult the medical institution where you had the procedure.
- Lumps or unevenness can develop at the injection sites. In particular, methods that add growth factors (such as bFGF) are not an approved use in Japan, and there have been reports of excessive fullness and lumps persisting long-term. Always confirm whether any additives are used and what they contain before the procedure, and go ahead only once you are satisfied with the explanation.
- Because your own blood is used, allergic reactions are considered unlikely, but the risk of infection from the injections is not zero. If strong swelling, warmth, or pain persists, seek medical attention promptly.
- PRP therapy falls under Japan's Act on the Safety of Regenerative Medicine. Medical institutions that provide it are required to file a regenerative medicine provision plan, so confirming in advance that this filing has been made is reassuring.
- People with blood disorders, those taking anticoagulants, and those with an infection or inflammation in the treatment area may not be able to have this procedure. Always tell your doctor about any medical conditions and medications in advance, and decide whether to proceed after an examination.
Spacing and combining with other procedures
If you have a wedding, photo shoot, or other big event, having the treatment at least 2–4 weeks beforehand allows time for swelling and bruising to settle. If you want the skin-quality changes to be ready in time for the event, keep in mind that results appear over several weeks to several months, and discuss a plan starting 2–3 months or more in advance with your doctor. If having multiple sessions, a common plan is said to be 2–3 sessions spaced about 1–3 months apart as a general guide. Because treatment proceeds while watching how your skin responds, follow your doctor's judgment on the number and spacing of sessions.
| Combined procedure | Timing | Wait time | Reason |
|---|---|---|---|
| Botox Injection | Same day OK | Sometimes combined on the same day | An injection that works on the skin's repair processes and an injection into the expression muscles have different goals, and as long as the areas do not overlap, they can often be done on the same day. Because swelling and bruising can overlap, your doctor will decide the order and whether to combine them. |
| Hyaluronic Acid Filler | Wait required | About 1–2 weeks as a guide (same day may be possible for separate areas) | Injecting into the same area on the same day can cause swelling and bruising to overlap, making it hard to tell which treatment is behind what you see. If you plan to divide the roles — hyaluronic acid for volume, PRP for skin quality — discuss the order and spacing with your doctor. |
| Pigment Spot Laser / Laser Toning | Wait required | About 1–2 weeks as a guide | Applying laser while the injection sites are still swollen or red stacks irritation on irritation and makes progress harder to assess, so it is considered safer to wait until the downtime has settled. |
| Needle RF (Microneedle Radiofrequency) | Wait required | About 2 weeks as a guide | If the downtime from fine-needle irritation and heat overlaps, swelling and redness can become more pronounced. Some clinics offer the two as a combination, but follow your doctor's plan on whether to have them in the same period. |
| HIFU (High-Intensity Focused Ultrasound) | Wait required | About 2 weeks as a guide | If heat-related swelling and puffiness overlap with the recovery of the injection sites, the results become hard to evaluate, so having them one after another with an interval is generally recommended. The best order depends on your goals, so discuss it with your doctor. |
