More and more girls are pursuing skin care to the extreme, and skin care research is becoming more and more in-depth. The word "skin barrier" is no longer unfamiliar.

The skin barrier is actually the first line of defense in the outermost layer of the human immune system, mainly composed of the stratum corneum and the sebum membrane. (Horizontal: The outermost layer of the epidermis has a variety of barrier functions and is an important functional area of ​​the skin barrier.)

The skin barrier acts as a protective barrier against external damage. However, when the skin barrier is disrupted, the health of the skin can become unbalanced and lead to various symptoms.

What are the symptoms of impaired skin barrier?

Symptom 1 Redness on the skin: If you have redness on your skin, especially on the sides of your cheeks, it basically means that there is a problem with the skin barrier function. When the skin barrier function is damaged, the capillaries and the abnormal expansion of the skin blood vessel wall are prone to red blood on the surface of the blood vessels.

Symptom 2 Skin becomes fragile and sensitive: A compromised skin barrier weakens the skin's resistance and immunity, making it more susceptible to infections and allergic reactions. At this point, the skin feels itchy, sore, and reddish.

Symptom 3 The skin becomes dehydrated and starts to slough: This is because the barrier is damaged, the skin's water retention capacity is greatly reduced, the skin is easily dehydrated, and the long-term lack of water leads to dehydration and peeling of the skin.

Symptom 4 The skin becomes dull and yellow: As you age and your face starts to turn dark and yellow, damage to the skin barrier can also lead to this result. This is due to the reduced ability of damaged skin to absorb nutrients, the stratum corneum is too thick and moist, nutrients are not absorbed by the skin, and the skin becomes unhealthy, dull and yellow.

After reading this, many girls will find that their face is often red, especially when the seasons change, the skin is very prone to allergies, and the use of some skin care products will cause the skin to sting.

Don't panic at this point. First of all, let yourself check the bad habit of "skin barrier" damage, do you also have it?

Habit 1 Excessive cleansing: Incorrect cleansing methods and products, over time, will inevitably damage the skin barrier and thin the stratum corneum.

Habit 2 Dry skin: If the skin is not hydrated enough, the metabolism of cells will slow down, resulting in dry, peeling, sensitive, dull skin.

Habit 3 Environmental factors: Factors such as ultraviolet rays, environmental pollution, dryness, and cold can damage the skin barrier.

Habit 4 Improper skin care: Improper skin care products, improper medical cosmetic repair, etc. will cause damage to the skin, resulting in skin allergies, inflammation, and reduced barrier function.

"Skin barrier damage" is not irreversible, don't worry too much, we can start small and establish the correct concept to maintain the skin barrier.

Concept 1 Gentle cleansing: Do not wash your face with hot or cold water. Also use a mild detergent.

Concept 2 Continuous moisturizing: To ensure that the skin has enough moisture, the skin's barrier function can gradually recover. After hydration, a lotion or cream should be used to enhance hydration.

Concept 3 Repairing redness: Using repairing skin care products can effectively regulate redness, sensitivity, roughness, damage and other problems.

Concept 4 Strict sun protection: Damaged skin barrier increases the chance of sunburn. Physical sunscreen is recommended. Not suitable for direct application of sunscreen.

Concept 5 Reduce makeup: Avoid makeup when the skin barrier is compromised. If makeup is required, choose mild makeup products, mainly light makeup, and choose mild makeup removers.
