When it is damaged, how should we repair it scientifically? Let us have a deeper understanding together.

什么是皮肤屏障？

The skin barrier is a "protective net" located on the outermost layer of the skin. It is mainly composed of the stratum corneum, lipid layer and transparent layer. Its main function is to lock in moisture and prevent external harmful substances (such as ultraviolet rays, pollution, bacteria, etc.) Invasion and at the same time regulate the skin's water-oil balance. The skin barrier is the "first line of defense" of our skin.

In modern life, there are many reasons for skin barrier damage. Common ones include:

1. 过度清洁: Frequent use of powerful cleaning products, especially soap-based cleansers, will destroy the natural oils on the surface of the skin and lead to a decline in barrier function.

2. Excessive exfoliation: Although exfoliation can help improve skin quality, excessive use of acids, matte and other products will damage the stratum corneum and cause damage to the barrier.

3. UV damage：长时间暴露在紫外线下，紫外线会破坏皮肤中的collagen和弹性纤维，同时也会损害角质层,削弱屏障功能。

4. environmental factors: Harsh environments such as cold, dry, and pollution can also put pressure on the skin barrier, causing water loss and weakening the barrier function.
