For the first 48 hours after laser tattoo removal, patients should keep the area cool, clean and covered, and avoid heat, swimming and hard exercise. Blisters and scabs are a normal part of healing and usually settle within one to two weeks, so they should be left alone. The skin then keeps fading the tattoo for weeks after each session, which is why sessions are spaced well apart.
Most of the work of laser tattoo removal happens after the patient has left the clinic. The laser breaks the ink up in a fraction of a second, but the body takes weeks to clear it, and how the skin is looked after in that time affects how well it heals and how soon the next session can go ahead.
This guide sets out typical laser tattoo removal aftercare to give your patients, drawn from clinical reviews and NHS patient information. Protocols vary with the laser, the settings used and the patient’s skin, so treat it as a starting point for your own aftercare advice rather than a replacement for it. For laser aftercare in general, rather than tattoo removal, see our guide to pre and post laser care.
Explaining what happens to the skin after laser tattoo removal
Straight after treatment, the tattoo usually turns white, then goes red and puffy. That’s the skin reacting to the laser breaking up the ink, and it’s worth telling patients to expect it.
The white reaction is called frosting. In their clinical review of laser tattoo removal in the Journal of Cutaneous and Aesthetic Surgery, Ho and Goh put it down to gas forming as the ink heats very quickly, and note it can last around 20 minutes. Redness, swelling and sometimes a little pinpoint bleeding follow. The Sandwell and West Birmingham NHS Trust patient leaflet says the redness can last 24 to 48 hours.
What patients don’t see is the slower process underneath. Tattoo ink sits in the dermis, the layer below the surface, in particles too large for the body to shift. The laser fires pulses lasting billionths of a second (nanosecond lasers) or trillionths of a second (picosecond lasers), which shatters those particles into smaller fragments. Immune cells then pick up the fragments and carry them away through the lymphatic system over the following weeks. The simplest way to put it to patients: the tattoo doesn’t disappear on the day. It fades as the body clears it.
Patients often ask whether the ink comes out in their urine. They won’t see ink in their urine. Most of the broken-down ink is picked up by immune cells and carried away through the lymphatic system, and how much eventually leaves the body is still being studied. A 2017 study in Scientific Reports found tattoo pigment in the lymph nodes of tattooed people, which shows that at least some ink stays in the body long term.
Laser tattoo removal healing stages, day by day
Most people move from frosting and redness, to blisters, to scabs, to new pink skin over roughly two weeks. The tattoo then carries on fading for several weeks after that.
| When | What patients will typically see | What to tell patients |
|---|---|---|
| Straight after | Frosting, redness, swelling, sometimes pinpoint bleeding | Cool the area, then apply the dressing as advised |
| Day 1 to 3 | Swelling settles; blisters may appear | Leave blisters intact; keep the area clean |
| Day 3 to 7 | Blisters dry; scabs form | Don’t pick; moisturise lightly if advised |
| Week 1 to 2 | Scabs fall away; itching; pink new skin | Don’t scratch; protect from the sun |
| Week 2 to 6 | Skin settles; the tattoo keeps fading | Normal routine; sun protection |
| Next session | Usually six to twelve weeks after the last one, at the interval you recommend | Book only once the skin has fully healed |

Everyone heals at a different speed, depending on skin type, the ink, where the tattoo is and the settings used.
Laser tattoo removal aftercare: the first 48 hours
The message for patients is simple: keep it cool, keep it clean and leave it alone. Most problems at this stage come from heat, friction or picking.
Patients can cool the area for short spells with a cold compress or an ice pack wrapped in a clean cloth if it feels hot or sore, but shouldn’t put ice straight on the skin. Any dressing stays on for as long as your protocol says. The Birmingham Regional Skin Laser Centre, for example, tells patients to remove theirs after 12 hours.
Advise rinsing gently with lukewarm water and patting dry. The same NHS leaflet says to avoid soap and perfumed products on the area for 48 hours. Patients should use only the ointment, gel or dressing you recommend, apply it with clean hands and wear loose clothing over the area. If an arm or leg was treated, raising it helps the swelling go down.
They should avoid saunas, hot tubs, hot baths, swimming and strenuous exercise while the area heals. Heat and sweat make swelling worse, and warm, damp skin is an easier route in for bacteria. A treated limb can also feel heavy, so the leaflet advises patients not to drive themselves home.
For soreness, tell patients to check with you or a pharmacist before taking anti-inflammatories.
Tattoo removal blisters: normal or a problem?
Blisters are a normal reaction to laser tattoo removal, not a sign that something went wrong. If they’re left intact, they’ll usually dry out within a week or two.
Why blisters form
The laser’s energy causes inflammation in the treated skin, and fluid can collect under the top layer as a blister. It’s common. In an online survey of 157 people who’d had laser tattoo removal, reviewed by Ho and Goh, 97% reported a local reaction such as blistering, swelling, crusting, redness or pain.
How long do tattoo removal blisters last?
Typically a few days to two weeks. The Birmingham NHS leaflet says blisters and scabs usually appear within a couple of days, and that the scab should fall off after 7 to 14 days. The roof of a blister protects the raw skin underneath, so patients shouldn’t pop it. If one is large and uncomfortable, it can be drained in clinic with a sterile needle, leaving the roof in place. Kirby and colleagues describe doing this in a small case series, followed by petroleum jelly and a dressing. Make clear that’s a job for you, not them.
What if a patient doesn’t blister?
It doesn’t mean the treatment hasn’t worked. Patients who expected to blister sometimes need to hear that. Blistering shows how the skin reacted on the day, not how much ink was broken up. How much patients blister varies between people, between areas of the body and from one session to the next.
When patients should call the clinic
Tell patients to get in touch if they notice signs of infection, such as redness that spreads or gets worse after the first couple of days, skin that feels hot, pain that gets worse instead of easing, pus, or a fever. Do the same if blisters are very large or very painful, if a rash or itching spreads beyond the treated area, or if anything else worries them. Your clinic should be their first call. If they can’t reach you, they should speak to their GP or call NHS 111, and go to A&E in an emergency.
Showering, exercise, sun and swimming: what to tell patients
Most patients are back to their normal routine within a few days. Swimming, sunbathing and anything that soaks or rubs the area should wait until the skin has healed. These timings are typical; adjust them to your own protocol.
| Activity | Typical timeframe | Notes |
|---|---|---|
| Shower | Usually from the next day | Keep it brief and lukewarm. No soap or perfumed products on the area for 48 hours. Pat dry. |
| Bath | Once scabs have fallen off, usually 1 to 2 weeks | Soaking softens scabs before they’re ready to come away. |
| Gym and running | After about 72 hours | Wait longer if sweat, clothing or kit rubs the area. |
| Swimming, saunas and hot tubs | Once scabs have dropped off, usually 1 to 2 weeks | Pools, the sea and hot tubs can slow healing and carry bacteria. |
| Sun and sunbeds | Cover up and avoid sunbeds throughout treatment | Use SPF 30 or higher on the area between sessions and for six months after their last one. |
| Shaving the area | Once the skin has fully healed | A razor can catch scabs and irritate new skin. |
| A new tattoo over the area | Once the skin has fully healed after the final planned session | Agree the timing with the patient and their tattoo artist. |

Sun protection is an important part of recovery. Ho and Goh say it should be stressed to every patient, because tanned skin competes with the ink for the laser’s energy. Most clinics won’t treat over a tan or fake tan, so sunburn or a holiday tan can push the next session back.
Laser tattoo removal side effects: what’s normal and what isn’t
Most side effects of laser tattoo removal are short-lived and part of normal healing. A few, like changes in skin colour, can take months to settle, and scarring is uncommon but possible.
Expected side effects include redness, swelling, blistering, scabbing and itching in the first couple of weeks. The skin can also turn temporarily lighter (hypopigmentation) or darker (hyperpigmentation). The Birmingham NHS leaflet calls darkening the most common risk, more likely in people who tan easily or have darker skin, and says it normally settles within three to six months. Lightening usually fades within a few weeks, though rarely it’s permanent.
Less common side effects include changes to skin texture and scarring. The Birmingham NHS leaflet says about 3 in 100 patients get a scar. Allergic reactions to the broken-down ink can also happen, and Khunger and colleagues’ review of tattoo removal complications lists them among the delayed effects. Some cosmetic, white, flesh-toned and red inks contain iron oxide or titanium dioxide, which can turn darker or even black after treatment. That’s why clinics often test a small patch first on cosmetic tattoos such as eyebrows or lip liner.
Most of these effects are temporary. An experienced practitioner, correct settings for the patient’s skin and ink, and good aftercare all lower the risk, but none of them removes it. It’s worth covering these risks at consultation, so patients know what’s normal before they leave.
Aftercare and healing in darker skin
Darker skin needs the same aftercare, with closer attention to pigment. Changes in skin colour are the side effect most worth watching for, and the Birmingham NHS leaflet notes that darkening is more likely in people who tan easily or have darker skin.
Wavelength is part of the reason. The 1064nm wavelength passes through the surface of the skin with relatively little absorption by melanin, the pigment that gives skin its colour, which is why it’s generally preferred for darker skin types. The 532nm wavelength, used for red and orange inks, is absorbed more strongly at the surface and calls for more caution. Skin type should shape the settings you choose, and a test patch first is sensible.
Afterwards, sun protection and leaving blisters and scabs alone matter even more, because extra inflammation raises the risk of pigment change. Ask patients to report any noticeable darkening or lightening at their next appointment, or sooner if it worries them.
How a tattoo fades between sessions
Fading isn’t instant. The body keeps clearing broken-down ink for weeks after each session, so the tattoo will often look lighter at six weeks than it did at two.
The Birmingham NHS leaflet says the body clears the ink fragments over roughly 8 to 12 weeks. That’s the reason for the gap between sessions. Treating again too soon means working on skin that’s still healing, before the body has cleared what the last session broke up. The usual standard is at least six to eight weeks between sessions, and some practitioners leave 8 to 12 weeks.
Tattoo removal after 1 session: what to expect
Patients should expect the tattoo to look lighter but not gone. Fading is often patchy, and the outline can still look sharp while solid areas soften. Black ink usually responds first. Ask them to wait a few weeks before judging: the first fortnight is mostly healing, and much of the fading comes later.
Tattoo removal after 3 sessions: what to expect
By three sessions, most tattoos look clearly lighter than at the start, particularly black and dark inks. Stubborn colours are slower. The Birmingham NHS leaflet notes that green, yellow and purple inks may clear slowly or not at all. Progress also tends to slow as the tattoo gets lighter, because there’s less ink left for the laser to target. You can see how other tattoos changed over a course of treatment in our before and after gallery.
How many sessions a tattoo needs depends on things like ink colour and density, the tattoo’s age and where it is on the body. Our guide to how many sessions laser tattoo removal takes goes through it.
Does the type of laser change how patients heal?
Not much. Q-switched (nanosecond) and picosecond lasers cause the same kind of short-term reaction, and the aftercare is the same for both.
The difference is pulse length. Picosecond lasers deliver shorter pulses, and early studies reviewed by Ho and Goh found them more effective than nanosecond pulses at clearing some inks. The same authors point out that much of that evidence comes from small studies, animal models or conference data, and call for more trials in people. For healing, the patient’s skin, the ink and the settings you choose matter more than which type of laser is used.
Asclepion makes both types. PicoStar® is a picosecond laser with 1064nm and 532nm wavelengths, and the NanoStar® family are Q-switched lasers with up to three wavelengths (532nm, 694nm and 1064nm). Our Q-switched vs picosecond comparison looks at the two in more detail.
Giving patients aftercare to take home
Advice given at the end of an appointment is easy to forget, so written laser tattoo removal aftercare that patients can take home does a lot of the work. Include your clinic’s contact details, the red flags above and when to book the next session. Asking patients to take photos as the skin heals also makes progress easier to judge between sessions.
For clinics interested in offering laser tattoo removal, we supply picosecond and Q-switched laser systems with clinical training and ongoing support. Our guide to offering laser tattoo removal at your clinic covers the practical side, and you can explore our laser tattoo removal devices or contact the team to discuss the options.
Patient questions about laser tattoo removal aftercare
These are the questions patients ask most often, with an answer you can give.
How long should I wait to shower after laser tattoo removal?
Most people can shower from the next day, unless their practitioner advises otherwise. Showers should be short and lukewarm, with no soap or perfumed products on the area for 48 hours, and the skin patted dry rather than rubbed.
When can I exercise after tattoo removal?
Patients should avoid strenuous exercise for about 72 hours, and longer if sweat or clothing rubs the treated area. Swimming should wait until the scabs have dropped off, usually one to two weeks. Your own protocol may set different timings.
Can I go in the sun after laser tattoo removal?
Patients should keep the treated area covered and avoid sunbeds throughout their course, with SPF 30 or higher on the area between sessions and for six months after the last one. A tan raises the risk of skin colour changes and can delay the next session.
Is itching normal after laser tattoo removal?
Yes. Itching is common as the skin heals and scabs form, usually in the first two weeks. Tell patients not to scratch or pick, because that can cause infection or scarring, and tell them what they can use to soothe it.
Can I get a new tattoo over a faded one?
Yes. Many people have a tattoo lightened so a tattoo artist can cover it. Advise patients to wait until the skin has fully healed after the final planned session, and agree the timing with them and their tattoo artist.
Can tattoos be 100% removed?
Not always. In one survey of 157 people reviewed by Ho and Goh, 38% achieved complete removal. The Birmingham NHS leaflet is clear that complete clearance can’t be guaranteed. Many people still get a tattoo light enough to be barely visible or easy to cover.
How long does laser tattoo removal take?
Each session is short, typically 10 to 30 minutes depending on the size of the tattoo. The full course takes much longer, often many months, because sessions are spaced weeks apart so the skin can heal and the body can clear the ink. Our guide to how many sessions laser tattoo removal takes explains what affects it.
Does laser tattoo removal hurt?
Most people find it uncomfortable. Clinics often use numbing cream, cooling air or both to make it more bearable. Afterwards the area can feel sore and hot for a day or two. For pain relief afterwards, patients should check with you or a pharmacist before taking anti-inflammatories.
What should I not do after laser tattoo removal?
Tell patients not to pick, scratch or pop blisters and scabs, and not to soak the area in baths, pools or hot tubs until the scabs have come away. They should avoid saunas and strenuous exercise for the first couple of days, and keep the area out of the sun and off sunbeds throughout their course.
