They concluded that tattooing would possibly hamper “sweat gland operate and could possibly be thought of a possible long-term complication or facet impact of this beauty process.”

For her half, dermatologist Greene stated {that a} attainable decline in physique cooling is not the one damaging well being impact of tattoos.
