As explained in the earlier question, it will take some time for it to be completely removed. The laser treatment can help to lighten the tattoo gradually. Certain ink pigments are easier to remove compared to the rest. The easiest are the dark blue or black ink, while red, yellow and green are more difficult. Also, it is easier to remove old tattoo than those new and fresh ones. Seek your doctor for advice if your tattoo or pigmented lesions does not seem to disappearing.
