"Nefretiti lines" refers to the vertical lines or bands that appear on the neck, often resulting from the contraction of the platysma muscle. These lines are sometimes also called "turkey neck" or "Nefertiti neck". They are a common sign of aging and can be addressed with treatments like Botox to relax the platysma muscle. The "Nefertiti lift" is a procedure that uses Botox injections to target and treat these lines, as the ancient Egyptian queen Nefertiti was known for her long, slender neck.
