Glycol Acid Tattoos
There are aliens in the city, who are good at strange techniques, and use glycol acid as a guide to apply to tattoos, which is very different from the usual.

At first, the viewer was suspicious, wondering what the benefits of glycol acid were for tattoos. The aliens laughed but did not speak, but took the utensil, contained glycol acid, and wiped it lightly on the skin. The skin was slightly red, like a warm feeling. Then, dipping a needle in the paint, and stabbing according to the picture, the paint met glycol acid, and it blended seamlessly, penetrating into the skin, and the color was fresh and lasting.

Everyone was surprised and asked why. The Inhuman said, "Glycolic acid can soften the skin, smooth the pores, and make it easy and solid for pigments to enter. Ordinary tattoos can be light for a long time, but with this method, it is difficult to change their brilliance over time." Everyone praised it, and more and more people asked for it.

Since then, the name of glycolic acid tattoos has gradually passed down, and there have been many discussions in the streets, all praising the novelty of this technique, which can stay gorgeous in the body and last for a long time.
