What causes verticle red lines on forhead right above eyebrows?

Vertical lines between the eyebrows, also called frown lines, are usually caused by repetitive muscle movement and aging. Squinting, frowning, or raising eyebrows can cause wrinkles on the forehead and between the eyebrows. As you get older, the skin loses its elasticity and collagen breakdown reduces fullness. This can make fine lines and wrinkles more noticeable.

Additional factors that can cause vertical lines on the forehead include:

- genetics: some people may be more likely to develop frown lines due to their genetics.

- sun damage: UV exposure from sunlight can damage the skin, leading to the loss of collagen and elastin, which can cause wrinkles.

- smoking: smoking damages the skin, leading to wrinkles.

- dehydration: not drinking enough water can lead to dry skin, which can make wrinkles more apparent.

- diet: a diet high in sugar and processed foods can contribute to premature aging and wrinkles.

- stress: stress can lead to the overproduction of cortisol, which is a hormone that breaks down collagen and elastin.
