Why is q-switched laser used in laser tattoo removal?

Tattoo pigment sits inside the skin rather than on its surface. A q-switched pulse is absorbed by selected ink and creates a rapid photoacoustic effect, breaking larger particles into smaller fragments. The immune system then clears some of those fragments over time. Different ink colours absorb different wavelengths, so the device and settings may change across a multicoloured tattoo. Professional tattoos, cosmetic tattoos, older ink, dense shading, and scarred areas can each respond differently.

The laser targets pigment, but the skin can still react with redness, swelling, temporary lightening or darkening, blistering, or crusting. Treatment is commonly staged so the skin can recover and the body can process the fragmented ink between visits.

Tell the clinician about tanning, active skin disease, medicines, previous reactions, and whether the tattoo contains cosmetic pigment. Keep the area protected from sun as directed. Clean the site gently, follow the dressing advice, and do not peel crusts or blisters. Ask whether the ink colour or location makes a different wavelength or test spot appropriate. Do not use home bleaching products on freshly treated skin unless specifically advised.

Contact the clinic if redness spreads, pain intensifies, drainage develops, or the area becomes increasingly warm or swollen. Seek prompt medical advice for fever, extensive blistering, breathing difficulty, or swelling away from the treatment site. A delayed colour reaction or persistent scar-like change also deserves review.
