This is what I found in Title 21
§21-841.
It shall be unlawful for any person to tattoo or offer to tattoo any person. As used herein to "tattoo" means to insert pigment under the surface of the skin of a human being, by pricking with a needle or otherwise, so as to produce a permanent indelible mark or figure visible on the skin. Provided, however, that the provisions hereof shall not apply to any act of a licensed practitioner of the healing arts performed in the course of his practice.
§21-842.
Any person violating the provisions of 21 O.S.1961, Section 841, shall be guilty of a misdemeanor and upon conviction thereof shall be punished by imprisonment in the county jail not to exceed ninety (90) days or payment of a fine of not more than Five Hundred Dollars ($500.00) or by both such fine and imprisonment
