Before your appointment, you can buy a wound and healing ointment or, better still, my tattoo cream on site. You should also make sure that you regularly apply cream to the area of your body to be tattooed a week before your appointment to protect it from drying out. However, please do not apply cream from the evening before your appointment. It is also advisable to drink plenty of water a few days before your appointment. You are welcome to shower before your appointment.
