It would be wise to consult with your dermatologist. Bring in the Latisse substitute. Be sure that you also have the box/container too since by FDA law the ingredients must be listed on the box, but not on the jar/tube itself. Your dermatologist should be able to figure out the ingredient to which you are allergic. If your problem is due to an allergic contact dermatitis, tincture of time and a mild corticosteroid should help.
However, if the problem is caused by a pigment, there is really not much to do for the next month or so. Your skin should gradually expel the pigment as the cells turn over.
If the problem persists, please see a physician skilled in the use of a laser.
