Answer: First, this is because some tattoo artists have not mastered the correct operation techniques when tattooing, which causes large skin damage and skin tissue hyperplasia. Such tattoos usually look like a raised pattern outline, but the color is very light. Second, because the tattoo artist penetrated the skin too deeply during the tattoo, and injected too much colorant under the skin. During the recovery process, the skin could not completely absorb the colorant, causing some of the colorant to accumulate under the skin and form The protrusions of the tattoo, because the pigment cannot be completely absorbed under the skin, such a tattoo will slowly spread out under the skin after a period of time, resulting in blurred patterns. An excellent tattoo should have almost no protrusions.
