Hello, generally speaking, nano-laser needs 2~3 times to achieve the effect, and ultra-picosecond laser only needs one time to achieve. Picosecond laser tattoo removal requires a certain course of treatment, the specific frequency is variable, and it is related to the following factors:
1. The area of the tattoo. The larger the tattoo area, the longer the treatment time, and the number of picosecond laser tattoo removals required will increase accordingly. Smaller tattoos require fewer tattoo removals.
2. The color of the tattoo. Tattoos come in many different colors, such as black, purple, green, blue, and color tattoos. The darker the color, the more picosecond laser tattoo removal times will be required.
3. Color materials used. The pigment used in tattooing will affect the difficulty of tattoo removal. Some pigments containing metal substances will be more difficult to remove tattoos, and the number of picosecond laser tattoo removal will be more.
