There is a horizontal line on the forehead

Sometimes people will find a horizontal line on their forehead, but they don’t take it too seriously because the symptoms are not so obvious. However, as the condition worsens, they will feel that their skin is lacking in moisture. Otherwise, their skin will always be dry, which will definitely cause wrinkles over time.

(1) Insufficient water in the body and skin

We know that the outermost layer of the skin is the stratum corneum, which can supply water from the body and absorb water from outside the body to keep the skin at an appropriate moisture content.

Generally speaking, the most suitable skin moisture content is 10 to 20%. If it is lower than 10%, the skin will be dry, rough and loose, and wrinkles will appear over time.

(2) Mental factors

They are often depressed, irritable, and withdrawn, and their faces often show sad, nervous, and restrained expressions. This expression affects the facial muscles and produces vertical or horizontal wrinkles, making people gradually look old.

(3) Long-term lack of sleep

Regular lack of sleep will damage the skin's regulatory function, causing your face to look haggard and prone to aging and wrinkles.

(4) Excessive exposure

Excessive exposure to the sun can cause skin damage, causing the skin on the face, neck and hands to become dry, thin and lose elasticity, and cause elastic fibers and colloid fibers to lose their normal functions, causing the skin to gradually become loose and wrinkled.

(5) Nutritional status

If the body is in good nutritional condition, the skin is adequately supplied with nutrients, the subcutaneous tissue is plump, and wrinkles appear late; if the body is in poor nutritional condition, the skin and muscle tissue will be malnourished, causing the skin to become rough and loose, and wrinkles will easily appear.

(6) The water temperature for washing your face is too high

The most suitable water for washing your face is warm water at around 30 degrees Celsius. If the water temperature is too high, the sebum and moisture in the skin will be absorbed by the heat, making the skin dry, and wrinkles will gradually appear on the face over time.

(7) Improper use of cosmetics

Using inappropriate cosmetics can damage the texture of the skin, and too much powder can cause fine wrinkles on the face.

It should be said that normal salt intake is not terrible. However, a survey by the French National Academy of Medicine shows that the French diet is generally salty, and their most commonly eaten French bread contains the highest salt content, with some containing as much as 25%-30%. Secondly, the salt content in bacon, meat products, and cheese is also quite high. Moreover, the French have a habit of cooking rice with salt water, which greatly increases their daily salt intake.
