What should you know about laser light tattoo removal?

Different ink colours absorb different wavelengths, so the device and settings depend on the pigment, depth, density, age, and location of the tattoo. A professional assessment also considers your skin tone and whether the tattoo is cosmetic, amateur, or professionally applied. Some pigments can change colour when exposed to laser energy, which is why a test area may be discussed.

Treatment usually affects the ink more than the surrounding skin, but redness, swelling, pinpoint bleeding, blistering, or temporary changes in pigmentation may occur. The tattoo often fades gradually rather than disappearing immediately. [Picosecond Laser](/technology/picosecond-laser/) and [Q-Switched Laser](/technology/q-switched-laser/) are examples of technologies used for selected pigment targets.

Tell the clinician about tanning, active skin disease, cold sores, medicines, allergies, and previous reactions to tattoo treatment. Keep the area protected from sunlight and arrive with clean skin. Do not pick flakes or blisters afterward; follow the dressing and cleansing instructions you receive.

Use loose clothing when the tattoo is in an area that rubs. Avoid swimming, heavy friction, and unapproved creams while the surface is healing. Future sessions should be planned only after the skin has recovered and the clinician has reassessed it.

Contact the clinic for worsening pain, spreading redness, pus, fever, extensive blistering, or a wound that is not healing. Urgent care is appropriate for facial swelling, breathing difficulty, or rapidly worsening symptoms. A lasting pale or dark patch should be reviewed before another session.

Ask which ink colours may respond, whether a test spot is appropriate, how the treatment plan will protect your skin tone, what aftercare is required, and how the clinician will handle a pigment that changes colour. Ask who to contact if the treated area becomes painful or infected.
