Causes and countermeasures for dry fine lines

Dry fine lines tend to form around the eyes and mouth. It can be a big shock to see them in the mirror or in a photo of yourself. If dry fine lines are left untreated, they can develop into deeper wrinkles. Learn the causes of their appearance and aim for beautiful skin with appropriate care.

What causes dry wrinkles?

The main cause of dryness is dryness. But did you know that there are actually a variety of other factors that cause dryness? Let's take a look at some of the most common causes of dryness.

The relationship between dryness and fine lines

Chronically dry skin causes the stratum corneum cells to shrink and the skin texture to become coarse. When the skin texture becomes uneven, the skin loses elasticity and shallow, fine wrinkles appear. In addition, when the moisture content of the stratum corneum decreases due to dryness, the skin loses flexibility and the skin's movement becomes temporarily fixed. This is exactly the environment that is likely to produce wrinkles.

Effects of UV rays

Collagen and elastin in the dermis layer are responsible for skin elasticity. UV-A, which has the longest wavelength among ultraviolet rays, reaches the dermis layer and directly damages collagen and elastin. In addition, ultraviolet rays also generate active oxygen. Active oxygen, which normally fights off bacteria and viruses, can also reduce the quality and quantity of collagen if it increases too much, so be careful.
