What should you know about CO2 laser tattoo removal?

CO2 lasers remove or vaporise very thin layers of skin and are commonly discussed for resurfacing. Tattoo removal generally requires energy that is absorbed by selected ink colours and breaks pigment into smaller particles for the body to clear. A CO2 treatment may therefore be the wrong match for the ink, skin type, tattoo depth, or tattoo location.

A consultation should identify every ink colour, whether the tattoo is professional or amateur, any previous removal, and your tendency to form raised scars or pigment changes. Darker skin can be more vulnerable to temporary lightening or darkening after heat-based treatment, so settings and alternatives need individual planning.

Ask for the proposed laser type and why it fits your tattoo. Pigment-selective options such as Picosecond Laser or Q-Switched Laser may be considered, depending on the pigment and your examination. Protect the area from tanning, disclose medicines that affect healing, and follow instructions about creams, shaving, and sun exposure.

Expect a staged plan rather than a single visit. The skin needs time between sessions to settle, and the response can vary by colour, depth, age, and placement. Do not pick crusts or apply unapproved products while the area heals.

Contact the treating clinician promptly for spreading redness, worsening pain, increasing warmth, pus, fever, or a wound that is not settling. Seek urgent assessment for facial swelling affecting breathing or vision, or a rapidly spreading blistering reaction. Persistent raised scarring or marked colour change also merits review.

Which laser is intended for each ink colour, and why is CO2 being considered? What skin changes are possible for my skin tone? How will you protect the surrounding skin, and what care is needed between sessions?
