Laser tattoo removal is a gradual process. A tattoo may look lighter after the first few sessions, but substantial clearance often requires repeated treatment and sufficient healing time.
Results vary according to the tattoo’s color, age, ink density, pigment depth, body location, the client’s skin type, the laser wavelength, treatment parameters, and the interval between sessions.
This article reviews published clinical examples to explain what laser tattoo removal can look like over time. These research cases were not treated by Mico Aes and should not be interpreted as guaranteed results for any particular machine or client.
Os resultados individuais variam. A remoção completa não pode ser garantida. A remoção de tatuagens a laser deve ser realizada por profissionais devidamente treinados, de acordo com os requisitos locais aplicáveis.
Casos publicados antes e depois de remoção de tatuagem a laser
Os exemplos a seguir vêm de pesquisas publicadas. Eles ilustram por que os resultados do tratamento e o número de sessões necessárias podem diferir significativamente.
Caso 1 publicado: Tatuagens azuis e pretas tratadas com lasers de 1064 nm
Um estudo retrospectivo de 2026 comparou tratamentos com laser Q-switched 1064 nm e picossegundo 1064 nm em 130 pacientes.
O estudo relatou:
- 73 pacientes receberam tratamento em picossegundos.
- 57 pacientes receberam tratamento Q-switched.
- A mediana do número de sessões foi de três no grupo de picossegundos e quatro no grupo Q-switched.
- Excelente depuração foi relatada em 78,1% do grupo de picossegundos e 54,4% do grupo Q-switched.
- No subgrupo de 108 tatuagens azuis ou pretas, foi relatada excelente depuração em 80% do grupo de picossegundos e 55,8% do grupo Q-switched.
- Os autores não relataram complicações graves durante o período do estudo.
- O acompanhamento foi limitado a três meses e a maioria das tatuagens eram azuis ou pretas.
O estudo incluiu fotografias mostrando a progressão do tratamento após diferentes números de sessões. Esses resultados se aplicam aos tratamentos e à população de pacientes examinados pelos pesquisadores. Eles não devem ser usados para prometer o mesmo resultado com outro dispositivo ou protocolo de tratamento.

Caso 2 publicado: Remoção de tatuagem em pele asiática
Um relatório publicado acompanhou seis pacientes coreanos com pele tipo IV de Fitzpatrick. As tatuagens eram principalmente pretas, com uma caixa contendo pigmento preto e vermelho.
Os pacientes receberam entre um e seis tratamentos com laser alexandrita de picossegundos de 755 nm. Os pesquisadores relataram mais de 75% de depuração em quase todos os casos.
No entanto, o estudo também relatou hipopigmentação pós-inflamatória parcial em três dos seis pacientes no acompanhamento de três meses. Este é um lembrete importante de que uma forte eliminação de pigmentos não significa que o tratamento esteja isento de riscos, especialmente em tipos de pele mais escuras.
Exemplos publicados incluem:
- Uma tatuagem na virilha fotografada antes do tratamento e após duas sessões
- Uma tatuagem nas costas fotografada antes do tratamento e após seis sessões
- Uma tatuagem preta e vermelha no ombro fotografada antes do tratamento e após uma sessão
- Uma tatuagem na mão fotografada antes do tratamento e após cinco sessões
- Uma tatuagem no peito fotografada antes do tratamento e após quatro sessões
- Uma tatuagem no braço fotografada antes do tratamento e após duas sessões

Caso publicado 3: Intervalos de tratamento mais longos
Uma série de casos de 2.024 documentou 12 pacientes tratados com lasers Q-switched ou de picossegundos. Suas fotografias compararam a aparência da tatuagem em longos prazos de tratamento.
Um exemplo mostrou quatro tratamentos realizados ao longo de 51 meses, com a fotografia final tirada sete meses após o último tratamento. Outros casos documentaram alterações em longos intervalos após uma ou mais sessões.
O relatório sugere que o desbotamento visível pode continuar durante períodos mais longos entre os tratamentos. No entanto, esta é uma pequena série de casos e não um ensaio controlado. Não deve ser utilizado para estabelecer um intervalo de tratamento universal para cada cliente.

What Tattoo Removal May Look Like After Each Session
The response immediately after laser treatment is not the final result. Tattoo pigment normally fades over time as fragmented particles are processed by the body.
Imediatamente após o tratamento
The treated area may develop temporary whitening or frosting. Redness, swelling, sensitivity, blistering, or crusting can also occur.
An immediate post-treatment image should never be presented as a completed result.
After One or Two Sessions
Some tattoos begin to show visible fading after the first sessions. The response may be uneven because ink density and pigment depth can vary within the same tattoo.
Dark pigments may respond differently from green, blue, yellow, white, red, or mixed pigments.
After Three to Five Sessions
Fading may become more noticeable, but visible pigment can remain. Some areas may respond faster than others, even when the same laser is used.
A photograph should state when it was taken. An image taken several months after a session cannot be compared fairly with an image taken immediately after treatment.
After Six or More Sessions
Some tattoos may become substantially lighter, while others require additional treatment. Dense professional tattoos, layered tattoos, scarred areas, cosmetic pigments, and certain colors may respond more slowly.
The number of sessions alone does not predict the final result.
Why Laser Tattoo Removal Results Vary
Cor de tatuagem
Different pigments absorb different wavelengths. Black and dark pigments are commonly treated with 1064 nm systems, while other colors may require different wavelengths.
Pigment ingredients are not always known, so treatment response can be difficult to predict from color alone.
Ink Density and Depth
Professional tattoos commonly contain dense pigment placed at a relatively consistent depth. Amateur tattoos may contain less pigment but can have uneven depth.
Idade da tatuagem
Older tattoos may already have experienced natural fading. Age can influence treatment response, but it is not the only determining factor.
Tattoo Location
Body location may affect clearance. Skin characteristics, circulation, lymphatic drainage, and healing response differ across the body.
Tipo de pele
Skin pigmentation affects treatment planning and the risk of hypo- or hyperpigmentation. Treatment parameters must be selected carefully, particularly for darker skin types.
Previous Treatment and Scarring
Previously treated tattoos may contain residual pigment at different depths. Fibrosis or scarring may also affect the response.
Intervalo de tratamento
The skin requires time to recover between sessions. Additional fading can continue after the visible surface has healed.
A qualified treatment professional should determine the interval according to the client’s skin response and the treatment protocol.
Tattoo Color and Commonly Considered Wavelengths
The following table is a general educational reference. It is not a treatment protocol.
| Cor da tatuagem | Commonly considered wavelength | Important consideration |
|---|---|---|
| Black and dark blue | 1064nm | Often used for darker pigments |
| Red and orange | 532 nm | Requires careful skin-type assessment |
| Green, blue and purple | 755 nm, 785 nm or another suitable system | Response depends on pigment composition |
| Yellow, white and skin-colored pigments | Varia | Some pigments may respond poorly or darken |
No wavelength should be selected solely from an online table. The tattoo, pigment response, skin type, device specifications, operator training, and local treatment requirements must all be considered.
How Many Sessions Does Laser Tattoo Removal Take?
There is no reliable universal answer.
The required number of sessions may depend on:
- Tamanho da tatuagem
- Pigment color
- Ink density and depth
- Professional or amateur application
- Tattoo age
- Body location
- Tipo de pele
- Existing scarring
- Previous removal treatments
- Comprimento de onda do laser
- Parâmetros de tratamento
- Healing response
- Time between sessions
Published cases range from visible improvement after one treatment to treatment courses requiring six, ten, or more sessions.
A consultation and test spot may be appropriate before establishing a treatment plan. Clients should not be promised complete clearance or an exact number of sessions based only on photographs.
Potential Side Effects and Complications
Expected short-term reactions can include:
- Vermelhidão
- Inchaço
- Temporary whitening
- Ternura
- Blistering
- Crusting
Possible complications can include:
- Hiperpigmentação
- Hipopigmentação
- Infecção
- Textural changes
- Cicatrizando
- Allergic or inflammatory reactions
A published case report documented an allergic contact dermatitis and widespread skin reaction following picosecond laser treatment of a multicolored tattoo. The authors associated the reaction with sensitivity to red tattoo pigment.
This does not mean that every client will experience an allergic reaction. It shows why treatment history, pigment colors, previous reactions, test spots, professional assessment, and follow-up matter.

Como avaliar fotos de antes e depois
Before trusting a laser tattoo removal comparison, check whether it provides:
- The number of completed sessions
- The laser technology and wavelength
- The treatment interval
- The date or stage of each photograph
- The tattoo colors
- The treatment area
- The client’s skin type, when appropriately reported
- Consistent lighting
- The same camera angle and distance
- Disclosure of cropping, editing, or enhancement
- A statement explaining whether treatment is complete
- The source and image-use authorization
A dramatic image without this information provides limited evidence.
Published Research Cases Versus Mico Aes Customer Cases
Published research cases and Mico Aes customer cases must be displayed separately.
Published Research Cases
These cases:
- Were treated by independent researchers or clinics
- May have used equipment from other manufacturers
- Are included for education
- Do not demonstrate the performance of a Mico Aes machine

Perguntas frequentes
Can laser treatment completely remove a tattoo?
Some tattoos may become substantially lighter or difficult to see. Others retain visible pigment. Complete removal cannot be guaranteed.
Quantas sessões normalmente são necessárias?
The number varies considerably. Published cases include improvement after a small number of treatments as well as treatment courses requiring six, ten, or more sessions.
Which tattoo colors are most difficult to remove?
Response depends on pigment composition and the available wavelength. Yellow, white, skin-colored, green, blue, and mixed pigments can present particular challenges.
Does laser tattoo removal cause scars?
Scarring is a possible complication, but it is not the expected outcome of every treatment. Client assessment, operator training, appropriate parameters, infection control, treatment intervals, and aftercare all matter.
Can tattoo pigment cause an allergic reaction after treatment?
Allergic and inflammatory reactions have been reported, particularly with certain colored pigments. Clients should disclose previous tattoo reactions and obtain a professional assessment.
Does skin tone affect treatment planning?
Yes. Skin pigmentation affects wavelength and parameter selection as well as the risk of pigmentary changes.
Are published before-and-after photos proof that a machine will work for everyone?
No. A research photograph documents a particular patient, device, protocol, and follow-up period. It does not guarantee the same result for another client or machine.
