The depth of the fogging is determined by the change in the color of the pattern. The pure black blocks of Totem are the heaviest of all colors, like some light fog, and the most imaginary part is the lightest, so their penetration depth is also different. Because inserting the needle too deeply can cause halo and scarring, and it is too light to be colored. Therefore, the depth of needle insertion should be the upper layer of the dermal papilla layer and the epidermal basal layer as the sedimentation layer.
