Vasocaine is an incredible American manufacured numbing anaesthetic, which is great to use during the tattooing process, especially on those painful parts of the body. The Vasocaine spray will also help reduce swelling for tattooing parts you need to keep going over to get that shading right! Simply spray the Vasocaine on to the area being tattooed and keep re-applying during the tattoo when needs be as it gradually wears off. The Vasocaine will take around 90 seconds to kick in and will last for 45-60 minutes. This product is a god send for those squeamish males and girls!!
