什么是皮肤屏障？

The skin barrier is a protective film located on the outermost layer of the skin. It is mainly composed of the stratum corneum, sebum membrane and transparent layer. Its main function is to prevent external harmful substances (such as ultraviolet rays, pollutants, bacteria, etc.) from invading the skin, and at the same time It locks moisture and prevents the skin from drying out. The skin barrier is like a "city wall" that protects our skin from external damage.

Why is the skin barrier so important?

1. prevent moisture loss: A healthy skin barrier can effectively lock in moisture and keep the skin moist and soft. Once the barrier is damaged and water loss accelerates, the skin will become dry, tight, and even peeling.

2. Resist external stimuli: Skin with damaged barriers is more sensitive to external stimuli and is prone to discomforts such as redness, itching, and tingling. Damaged barriers can also lead to reduced skin resistance to the external environment and increase the risk of allergies and infections.

3. maintaining skin health: A healthy skin barrier is the foundation of overall skin health. If the barrier is damaged, skin problems such as acne, eczema, rosacea, etc. are more likely to occur.

Causes of skin barrier damage

1. excessive cleaning: Using cleansing products with too strong cleaning power, especially frequent use of soap-based cleansing, will destroy the natural sebum film of the skin and cause damage to the barrier.

2. Excessive exfoliation: Although exfoliation can help improve skin problems, excessive use of exfoliation products, especially chemical exfoliation products, can damage the stratum corneum and lead to a decrease in barrier function.

3. 环境因素: Harsh environmental conditions, such as dryness, cold, pollution, etc., can put pressure on the skin barrier and cause its function to be weakened.

4. Medical beauty operation: Although medical and aesthetic operations such as lasers, microneedles, and chemical resurfacing can improve skin problems, they can also cause certain damage to the skin barrier. Improper postoperative care can easily lead to damage to the barrier.

5. 生活习惯：不良的生活习惯，如熬夜、饮食不均衡、压力过大等，也会影响皮肤屏障的健康。

2. 减少去角质频率：屏障受损期间，应减少去角质的频率，如果需要去角质，可以选择低浓度的果酸或水杨酸产品，并在使用前做好皮肤测试。

3. strengthen protect wet: Moisturizing is the key to repairing the skin barrier. Choose moisturizing products containing hyaluronic acid, glycerol, ceramide, squalane and other ingredients to help the skin lock in moisture and repair the barrier.
