Usually, if you take some eye tattoos , they will last forever. Our skin is the canvas of body art. Tattoo is just like drawing on our skin, it is permanent and can't be reversed easily.Human skin consists of three layers: epidermis, dermis and hypodermis.Epidermis is the surface of our skin and it is replaced by a new layer of cells every month. If tattoo pigments stay in this layer, they would disappear every month. Actually, as the needles of tattooing instrument hurt your skin and make pigments go into your tissue, those pigments stay in dermis, which doesn't "update" monthly. You may feel hurt when you take some eye tattoos. Itdepends on the part where you tattoo onto. The more delicate the area you choose the more pain you will have.
