Downtime after laser ink removal:
frosting, blisters, scabs and what is not normal

What happens on the day of laser tattoo removal?

On the day, the tattoo turns white as the laser passes over it. Picosecond pulses fragment the ink particles mainly by a pressure effect, and the rapid heating releases gas in the dermis that scatters light; the white frosting is that gas, and it fades quickly, leaving the ink looking much as it did. Frosting is the endpoint the laser is set to, and it is the reason the ink looks unchanged when you leave: the laser does not remove ink, it fractures it small enough for the immune system to carry away between treatments. The tattoo removal page explains why the plan is staged.

Once the frosting fades the area is red, swollen and tender, with pinpoint bleeding where the ink was dense. The swelling can be marked on a forearm, ankle or wrist, where there is little tissue to absorb it, and a tattoo over a joint can make the joint feel stiff. A cool compress eases the swelling. The area is cleaned, dressed with ointment and a light covering, and you leave with written aftercare; the tattoo removal aftercare page sets it out in full.

Settings are chosen by Dr Sin Yong for the ink colour, density and depth and for your skin type, because the same energy that fractures black ink is also absorbed by the melanin in medium and darker skin; cosmetic tattoos on the brows or eyelids get a small test area first, since some pigments darken.

What do the following days look like?

Over the following days the area passes through a sequence. Blisters can rise over the most heavily inked parts, sometimes small and scattered, sometimes a single larger one; they are the skin lifting over fluid and are part of healing, not a sign that something went wrong. Left intact, the roof of a blister protects the skin underneath while it heals. Blisters then dry and the area forms scabs, which tighten, itch and come away on their own to leave pink new skin. Itching during this phase is common and eased with moisturiser rather than scratching.

The ink itself looks unchanged, or even slightly darker through the inflammation, during this phase. Fading happens gradually between treatments as the immune system clears the fragments, which is why the next treatment waits until the skin has healed completely and why progress is judged at review rather than in the mirror soon afterwards.

Scab care

• Clean gently with water, pat dry, apply the ointment given and cover with a light dressing while the skin is open
• Leave blisters intact; if one is large or tense, send a photograph rather than lancing it
• Let scabs separate on their own; picking is the commonest route to a scar
• No soaking, swimming, baths or saunas until the skin has closed; showers are fine
• No friction from straps, waistbands or tight sleeves over the area, and no shaving over it until healed

“The frosting is not ink leaving. It is gas. The ink leaves between treatments, carried by your own immune system, which is why I will not treat skin that has not finished healing.”

Dr Sin YongOn what happens after laser tattoo removal

What is not normal after tattoo removal, and when should you call?

Not normal: crusts that are thick, yellow or oozing; redness that spreads beyond the tattoo; pain, swelling or warmth that increases rather than settles; pus; itching that spreads beyond the tattoo or hives elsewhere; or fever. Each is photographed and sent rather than watched. Broken blisters can become infected, which is the reason they are left intact and the area kept covered, and an infected tattoo site is a route to scarring that aftercare is designed to avoid.

Some inks, red pigments in particular, can provoke an allergic reaction as the laser releases them, usually local itching and swelling and, rarely, something more widespread. Swelling of the lips, tongue or throat with difficulty breathing is an emergency.

Pigment change after healing

Once the scabs have gone, the new skin is pink. Two things can follow as the skin settles. A patch darker than the surrounding skin is post-inflammatory hyperpigmentation, the response of medium and darker skin to any surface injury, made more likely by sun on healing skin and by picking; the post-inflammatory hyperpigmentation page explains how it is assessed and why it usually settles. A patch paler than the surrounding skin is hypopigmentation, where melanocytes have been suppressed or lost by the laser energy along with the ink, and it can be slow to recover; the white spots after laser article explains the difference between suppressed and lost pigment. Both are reviewed before the next treatment, because they change the settings, and both are the reason sun protection continues long after the scabs have gone. Contact the clinic during clinic hours; the complication care page lists what goes to an emergency department the same day.

Can I exercise, swim and go in the sun after tattoo removal?

Exercise that makes the area sweat or rub against clothing waits until the blisters have dried and the scabs are settled; sweat stings open skin and friction lifts a scab early. A tattoo over a joint can be stiff and is better rested. Swimming, baths and saunas wait until the skin has closed completely, because soaking softens scabs and pools carry bacteria into open skin.

Sun is the rule that outlasts the others. Keep the area covered or shaded while it heals, and once the skin has closed use a broad-spectrum sunscreen on it every day between treatments; sun-exposed or tanned skin raises the risk of pigment change in medium and darker skin, and a tan over the tattoo changes the settings that can be used at the next visit. Make-up or concealer over a healed tattoo is fine; over a scab it is not. Flying is usually fine with dressings; the flying after treatment page covers what to carry and when to message.

How should you plan tattoo removal around work, sport and holidays?

Plan around the blister and scab phase, which is visible and needs a dressing, and around sun. A tattoo on a forearm, hand or ankle is hard to hide and easy to knock, so a treatment shortly before a beach holiday, a wedding or a sports event is the wrong order; a holiday in the sun immediately before a treatment is also wrong, because tanned skin shifts the balance toward pigment change. Clothing that covers the area without rubbing it, and a job that does not soak the hands, make the early phase easier.

Removal is staged because the body clears fragmented ink slowly and the skin must recover fully between treatments; treating again before it has healed raises the risk of scarring and pigment change without clearing more ink. No number of treatments is fixed in advance, and each next step is decided at review from how the tattoo and the skin look, including any dark or pale patch from the last one. Whether your tattoo, ink colours and skin type suit laser removal at all is decided at consultation.
