The Tattoo Goo Healing Can 21 gr was developed to promote the most natural healing possible and ensure the maintenance of the original tattoo colors in the healing process. The product is 99% natural and contains no chemicals of any kind in its composition. Directions for use: After washing with the Gel, apply a very thin layer of healing gel 3 times a day for 10 to 15 days. The scarifier when used in excess may cause an allergic reaction. Note: Applying the healing agent without first washing with the Gel may cause an allergic reaction due to the presence of bacteria and dead cells. Do not share your scarifier with another person, such a procedure would raise the risk of cross-contamination.
