Which laser is best for tattoo removal? PicoWay® explained

The best laser for removing a tattoo is the picosecond laser, and in particular the PicoWay® by Candela. This latest generation technology breaks ink down into far finer particles than older lasers, while releasing less heat. The result is often faster fading, less trauma for the skin and better safety, including on darker skin tones and on colours known to be difficult. Individual results vary.

One point is worth making straight away. The best laser is not enough on its own. The outcome depends as much on the technology as on the person operating it and on how well the laser suits your tattoo. A picosecond laser in the hands of a trained skin therapist, with settings adjusted to your skin and to the colour of your ink, is what gives you the best chances. This article explains how a tattoo removal laser works, what sets picosecond apart from nanosecond lasers, why the PicoWay® by Candela performs so well, and why trained hands and a controlled environment are part of the equation. At Ray studios, a centre dedicated exclusively to laser tattoo removal, this is precisely the laser we use.

How does a tattoo removal laser work?

A tattoo removal laser works by targeting ink pigments with calibrated light, breaking them up so that the body can eliminate them. Understanding this principle helps you see why some technologies are more effective than others.

Tattoo ink sits in the dermis, the deeper layer of the skin. These pigment particles are too large for the body to clear away, which is why a tattoo is permanent. The laser sends out light at a wavelength that is absorbed by the pigments, while passing harmlessly through the healthy skin around them. This selectivity is the key to the treatment: the energy concentrates on the ink, not on the surrounding tissue.

Under the effect of the laser, the ink particles shatter into smaller fragments. The immune system and the lymphatic system then take over and gradually clear these fragments away, session after session. The finer the fragments, the more easily and quickly the body eliminates them. This is exactly where the difference between laser generations lies. The ability to break ink down into tiny particles determines both how quickly the programme progresses and the quality of the result.

Nanosecond or picosecond laser: what is the difference?

The main difference between a nanosecond laser and a picosecond laser lies in the length of their pulses and in the way they break up ink. This technical distinction has concrete consequences for effectiveness and comfort.

The nanosecond laser, often called Q-switched, emits pulses lasting around a billionth of a second. It works mainly through a thermal effect, in other words through heat, and breaks ink into relatively large fragments. This technology remains effective and well proven, particularly on black and dark blue, and it has a long safety record. For many years it was the reference for tattoo removal.

The picosecond laser emits pulses a thousand times shorter still, in the order of a trillionth of a second. Instead of relying mainly on heat, it produces a mechanical effect, a kind of pressure wave that shatters the ink. This mode of action breaks pigments into much finer particles and releases far less heat. Studies show that picosecond lasers achieve better clearance rates in fewer sessions, with a lower risk of pigmentation changes, particularly on darker skin tones. It is today the most advanced generation of tattoo removal technology.

Why is the picosecond laser the best choice?

The picosecond laser is considered the best current choice for tattoo removal because it combines several advantages that older lasers do not offer to the same degree. These benefits all follow from its finer fragmentation and its lower heat output.

The first advantage is effectiveness. By breaking ink into tiny particles, the picosecond laser makes it easier for the body to clear them, which often translates into fewer sessions than with a nanosecond laser. The second advantage is respect for the skin. By releasing less heat, this technology limits trauma to the surrounding tissue, which favours faster healing and helps reduce the risk of marking or scarring.

The third advantage concerns safety on darker skin tones. Skin rich in melanin is more sensitive to pigmentation changes during tattoo removal. The more controlled energy delivery of the picosecond laser, with less heat, makes the treatment safer for these skin types. The fourth advantage relates to difficult colours. Some bright shades resist older lasers, whereas the picosecond laser, especially when it offers several wavelengths, treats a wider spectrum of colours. Together, these strengths explain why picosecond has established itself as the best option for the majority of tattoos.

The PicoWay® by Candela: a benchmark picosecond laser

The PicoWay® by Candela is a picosecond laser that ranks among the best performing systems on the market, thanks to its combination of wavelengths and its very short pulses. It is the laser used at Ray studios for all treatments.

What sets it apart is its three wavelengths: 1064 nm, 532 nm and 785 nm. This range matters, because each wavelength effectively targets part of the ink colour spectrum. The 1064 nm wavelength treats black and dark shades, as well as certain deep blues and greens. The 532 nm wavelength targets warm colours such as red and orange. The 785 nm wavelength works on shades known to be difficult, such as blue and green. Having these three wavelengths in a single device means a multicoloured tattoo can be treated without compromise, without having to give up on certain colours.

The PicoWay® also delivers extremely short pulses, which maximises the mechanical fragmentation effect while limiting heat. It is suitable for all skin types, which makes it a safe tool across a wide range of skin tones. This versatility makes it particularly relevant for multicoloured tattoos, cover-ups and tattoos already treated elsewhere. It is this combination of precision, power and colour coverage that explains its reputation.

Why do several wavelengths matter?

Several wavelengths matter because no single wavelength can effectively remove every ink colour. Each shade absorbs light differently, which means the wavelength has to be matched to the colour being targeted.

The principle is one of matching light to pigment. Black absorbs all wavelengths and therefore responds well to several of them, particularly 1064 nm. Red and warm colours react to 532 nm. Blue and green, often the most stubborn, need a specific wavelength such as 785 nm. A laser with only one wavelength would inevitably leave certain colours behind, or would require far more sessions for a partial result.

This is why a multi-wavelength laser such as the PicoWay® is a major asset for coloured tattoos. The skin therapist can select the wavelength suited to each shade present in the tattoo, and so treat the whole design consistently. For an entirely black tattoo, one wavelength is often enough. For a tattoo rich in colour, the versatility of the device makes all the difference. Ink colour remains one of the main factors that make a tattoo difficult to remove, and having the right tool for each shade clearly improves the chances of complete clearance. Individual results vary.

Is the best laser enough for a good result?

No, the best laser is not enough on its own, because the result depends just as much on the expertise of the skin therapist and on how well the treatment suits your tattoo. The technology is a necessary condition, not a guarantee in itself.

A high performing picosecond laser has to be set correctly to deliver its full potential. The choice of wavelength, power and session spacing depends on the colour of the ink, its density, its depth, the area treated and your skin type. Incorrect settings, even with an excellent device, can lead to a poor result or to unwanted effects. Conversely, the right settings, adapted to each case, get the most out of the machine. That is what a trained skin therapist provides, assessing these parameters and adjusting the treatment.

This is also why tattoo removal should never be improvised. Trained skin therapists, correct laser settings and a controlled environment are what make the difference between a well managed programme and an unpredictable one. At Ray studios, every session is carried out by a skin therapist, from the initial assessment through to follow-up, and the programme is structured by the RsAP® (Ray studios Advanced Performance) treatment protocol. The best laser and the best supervision therefore go together. It is their combination that puts the odds in favour of clean, safe fading. The before and after results shown on our site illustrate what this combination can achieve. Individual results vary.

Is the picosecond laser suitable for every tattoo and every skin?

The picosecond laser is suitable for the vast majority of tattoos and skin types, which makes it the most versatile technology for tattoo removal. Its safety on darker skin tones and its ability to treat difficult colours widen the range of tattoos that can be treated.

The PicoWay® is suitable for all skin types, from the lightest to the darkest. This compatibility is an important advantage, because skin rich in melanin was more delicate to treat with older lasers, due to the risk of pigmentation changes. The more controlled energy delivery of the picosecond laser makes the treatment safer for these skin types. As for tattoos, the technology treats old and recent work alike, black designs as well as multicoloured tattoos, and suits cover-ups or tattoos already treated elsewhere.

It is important to stay realistic, however. No technology removes every ink with the same ease. Some light colours, such as white, yellow or certain pastels, remain more resistant, even with a picosecond laser. The number of sessions and the final result depend on a combination of factors specific to each tattoo. That is why a prior assessment by a skin therapist is essential. It makes it possible to determine precisely what the laser can achieve on your tattoo, rather than relying on a general promise.

Your initial consultation

To find out how your tattoo will respond to the picosecond laser, the best step is an initial consultation with a skin therapist at Ray studios. It is the opportunity to have your tattoo assessed and to get an estimate suited to your case.

At this consultation, the skin therapist looks at the colour, density and location of your tattoo, examines your skin type, then produces an RTP® (Ray Tattoo Profile) projection of the number of sessions and explains the Full Remove plan: unlimited sessions at a single fixed price. You find out how the PicoWay® will be used on your tattoo, with which wavelengths and according to which protocol. You leave with a complete view of the programme.

This assessment cannot be done remotely. Analysing the ink and the skin requires an in-person examination. It is the only way to determine the right settings and to draw up a precise treatment plan. Book an appointment at one of our centres to meet a skin therapist and get your answers.

Key points

The best laser for removing a tattoo is the picosecond laser, in particular the PicoWay® by Candela. Unlike older nanosecond lasers, which work through heat, the picosecond laser breaks ink up through a mechanical effect and fragments it into very fine particles, which often means fewer sessions, faster healing and better safety, including on darker skin tones. The PicoWay® adds three wavelengths that cover the full range of ink colours, a major asset for multicoloured tattoos. The best laser is not enough on its own, though: the result depends on the expertise of the skin therapist and on how well the settings suit your tattoo and your skin. Individual results vary.

To find out how your tattoo will respond, the simplest step is to speak to a skin therapist. At Ray studios, that starts with an initial consultation. Find your centre and book yours.
