Same before care instructions as initial procedure are to be applied to touch up procedures. Touch-ups, if needed, will NOT be done before 6 weeks from the date of your procedure, and must be performed within 12 weeks of your procedure in order to be $50. After 12 weeks, the touch up charge will be $10 for each additional week. Changing your mind on the thickness will cost $100. Failure to follow post-treatment instructions may cause loss of pigment, discoloration or infection and will not be considered a touch-up, but a redo...this will cost $200.
