EDIT: Moles are caused by concentrated pockets of pigmentation and sunlight. Not marks. You can have dark scars because of shots, though.
Injections can effect pigmentation in that area, because moles are formed by pigment cell clusters, an injections can cause the pigment cells to cluster in that area.
OOC:No, they can't. That isn't how it works.

A mole is a type of melanocyte. Freckles are also grouped into this category. Melanocytes are located at the bottom layer of the epidermis, and through a process called melanogenesis, produce the pigmentation we see as moles. There are thousands upon thousands of melanocytes per square millimeter of skin. The cells that cause moles are already in the location where the mole occurs. Nothing causes those cells to cluster in one area. The cells don't move around.

There are two ways to start melanogenesis in melanocytes. Vitamin D, retinoids, certain hormones and UV exposure all stimulate melanocytes to the point where they undergo melanogenesis and darken the skin. In some cases, this is the impermanent tan or freckle. In other cases, it is the semi-permanent mole. That is where a mole comes from. Getting punctured in anyway does not cause a mole. It causes a scar.
