There is a vertical line between the eyebrows, what's the cause and what should be done?

There is often a vertical wrinkle between the eyebrows, commonly known as the glabellar line or "number eight wrinkle." Possible causes include skin aging, frequent frowning, dry skin, malnutrition, and trauma. It is recommended to address this issue through methods such as collagen supplementation, massage, maintaining skin hydration, balanced nutrition, and medical aesthetic treatments. The analysis is as follows:

1. Skin aging: With age, the skin loses collagen, and subcutaneous tissue atrophies, leading to skin laxity and wrinkles, including vertical lines between the eyebrows. Consuming collagen-rich foods such as fish skin, pig feet, and chicken claws can help replenish collagen and maintain skin elasticity.

2. Frequent frowning: Glabellar lines are often related to habitual facial expressions. Overcontraction of the frowning muscles can cause vertical wrinkles between the eyebrows. Gently massaging the area between the eyebrows with the fingertips in the morning and evening can promote blood circulation, help relax muscles, and reduce wrinkle formation.

3. Dry skin: Dry weather and not using skincare products can lead to loss of skin moisture and nutrients, resulting in glabellar lines. It is recommended to maintain skin hydration by drinking adequate warm water and using effective moisturizing skincare products.

4. Malnutrition: Long-term picky eating or dietary bias may lead to insufficient nutrient intake, leaving the skin deficient in essential nutrients and resulting in wrinkle formation. Ensuring sufficient intake of nutrients, including vitamins and proteins, and consuming more antioxidant-rich foods such as blueberries, strawberries, and spinach can help combat free radicals and delay skin aging.

5. Trauma: If the eyebrow area sustains external impact, local skin tissue may be damaged, leading to scarring or wrinkles. If the vertical wrinkle is particularly noticeable, one may consider undergoing medical aesthetic treatments at a hospital, such as hyaluronic acid fillers or fractional laser therapy. These treatments can stimulate collagen production in the skin and help reduce vertical wrinkles.

In daily life, it is recommended to maintain good sleep habits, as sufficient sleep can promote skin self-repair.
