Sefer Ha’mitzvos Ha’Katzar (The concise book of mitzvos) By the Chofetz Chaim
This book lists the Torah mitzvos that can be observed today
Second Section – the Negative Commandments
163. It is a negative commandment “do not have a tattoo on one’s flesh”
As it states in Vayikra (Leviticus) 19:28, “do not place a tattoo on yourself.” A tattoo is making an incision on one’s flesh and filling it with ink or colors. A person who transgresses this is given lashes.
This applies in all places and at all times, for men and for women.
4. Be kind to yourself. Speaking badly even about yourself is unethical.
