1. In terms of ingredients, it can be divided into organic pigments and inorganic pigments
Organic colorant: It is soluble in water, the colorant is very dilute, has no precipitation, and its stability is poor. The colorant is easy to be swallowed by macrophages and then discharged by the lymphatic glands. It is highly irritating and prone to rejection.
Inorganic pigment: insoluble in water, with pigment particles, strong stability, not easy to decolor, less negative effects, no color change, it is still in powder form after the skin is tattooed, and it is difficult to be swallowed by macrophages.
2. From the aspect of state, the pigments can be divided into paste pigments and liquid pigments
Paste-like pigments are advanced tattoo pigments. The effective ingredients and concentration of the pigments are twice stronger than those of liquid pigments. The coloring is fast, the color is stable, and the effective ingredients are high. The moisture on the paste-like pigments is made of glycerin. It is not volatile and easy to store. It is a very good lipophilic and hydrophilic colorant. It is suitable for any skin. It is also because it is not volatile, which increases the time for skin absorption.
