Most of us have more wrinkles under eyes when compared to forehead. The researchers stated that the oil-secreting glands are the main reason behind it.
A new study conducted on cadavers suggests that differences in the number of oil-secreting glands in the skin may help explain why wrinkles are shallower in the forehead than in the outer eye area.
The researchers suspect that the presence of oil-secreting glands and a thinner inner layer of skin or dermis let the skin deform more easily and might be a cause for the development of wrinkles.
The study is published in Journal Clinical Anatomy.
