Contraindications to laser tattoo removal — when the treatment cannot be done

Absolute contraindications to laser tattoo removal

The following conditions rule out treatment until they resolve or end:

• Pregnancy and breastfeeding. Shattered ink particles enter the lymphatic system and bloodstream — the effect on a foetus or infant is unknown. We apply the precautionary principle. More in our article on tattoo removal during pregnancy and breastfeeding.
• Photosensitising medications. Isotretinoin (for acne) must be discontinued for at least 6–12 months before treatment — the skin is extremely sensitive while on it. Other photosensitisers include some antibiotics (e.g. doxycycline), St. John's Wort supplements and certain blood pressure medications. Disclose all medications at consultation.
• Active skin infection or open wounds at the treatment site. Laser on infected skin can spread the infection. We wait until full healing.
• Photosensitive epilepsy. Laser flashes can trigger seizures.
• Fresh tan or self-tanner on the treatment area. We require no active tan for at least 4 weeks before each session. More on how sun affects removal in our article on tattoo removal and sun exposure.
• Sunburn at the treatment site. The skin must be healthy and unirritiated.

Relative contraindications — timing or individual assessment

The following conditions do not automatically rule out treatment but require discussion and often deferral or a modified approach:

• Diabetes. Healing is slower and the immune response differs. Well-controlled diabetes (HbA1c below 7%) is generally manageable. Details in our article on tattoo removal with diabetes and other conditions.
• Immunosuppressant medications. These slow pigment clearance and healing. Assessed case by case.
• Active autoimmune conditions (e.g. lupus, psoriasis in the treatment area). A flare-up of symptoms after laser treatment is possible. We defer until remission.
• Chemotherapy within the past 6 months. The immune system is suppressed. We wait for oncologist clearance and health stabilisation.
• Anticoagulants (blood thinners). Increased bruising risk, but treatment is usually feasible. Discussed individually.
• Keloid tendency. Risk is site-specific — someone with keloids on the chest may not develop them on the arm. We assess the specific area and perform a test spot. Details in our article on keloid tendency.
• Melasma or vitiligo near the treatment area. Affects parameter selection. We discuss individual approach.

What to disclose at consultation

For a reliable assessment, at consultation please share:

• All medications — prescription, OTC and supplements.
• History of chronic and autoimmune conditions.
• Previous laser or other skin treatments.
• Recent sun exposure or sunbed use near the tattoo.
• Pregnancy, breastfeeding or plans to become pregnant.
• Any history of keloid or abnormal scarring.

Many "contraindications" are a matter of timing, not a permanent state. If you are on isotretinoin, we simply wait a few months. If you are pregnant, we begin after weaning. We assess each case individually.
