This product is highly effective on broken skin. Use Vasocaine during tattooing, piercing or other broken skin procedures. Vasocaine is a strong anesthetic, which hits quickly. Where speed of anesthesia and ease of use are important, just spray or wipe throughout your job, let sit 90 seconds, and you are good to go. Always remove the product thoroughly before tattooing. Because of the added ingredient of a vascular constrictor, you will also experience a reduction in bruising and bleeding with this product. The healing of tattooing is not affected by its continued use throughout a procedure. This liquid 4oz anesthetic comes with a spray top. Developed originally for relief of anorectal disorders, this powerful 5% lidocaine liquid anesthetic is for use during procedures. It is safe for use on all procedures except eyeliner. It also contains a vascular constrictor to aid in reducing swelling and bleeding. Because this product contains epinephrine, a vascular constrictor, it should only be used once in each area. Remember to always remove anesthetics before continuing with your procedure.
