Regular tattooing is typically for decorative purposes and is permanent, while cosmetic and medical tattooing serve functional roles. Cosmetic tattooing enhances facial features like eyebrows, lips, or eyeliner. Medical tattooing is often used to address issues such as scar camouflage, areola restoration after breast surgery, or the replication of hair follicles on the scalp for those with hair loss. These procedures are also semi-permanent and employ specialized techniques and pigments, distinct from those used in regular tattooing, tailored to their specific applications.
