According to the French beautician, this proverb means that because people who live by the sea usually consume more salt, which increases tissue oedema and affects the skin’s metabolism, their skin is prone to wrinkles, which naturally affect their beauty. People in the mountains, on the other hand, eat less salt and tend to have smooth and delicate skin. In fact, wrinkles are also related to UV intensity, time spent working outdoors, diet structure and genetic factors, and cannot be generalised.
