What causes skin barrier damage?

Skin is a relatively important surface tissue. It is everywhere on the human body. It is the strongest line of defense for people, preventing a large number of viruses from directly invading the human body. Therefore, protecting your skin is protecting your health. There is a very strong defensive tissue in the superficial layer of the skin, called the skin barrier. It is the strongest barrier separating the inside of the body from the outside world. Generally, it is difficult for bacteria and viruses to reach here unless the skin barrier is damaged. Due to the influence of modern life and environment, the number of people with damaged skin barrier has greatly increased. Let’s take a look at how damaged skin barrier is caused.

1. Improper skin care. This is also the main reason. Many people had good skin, but their skin became worse after using skin care products. Because they do not have a systematic and scientific understanding of the skin, and know nothing about skin care products, they form bad skin care habits, such as excessive exfoliation, excessive cleansing, hormonal skin care products, etc.

2. Other reasons include genetics, but it is very rare. Insufficient use of medications, oral and topical medications, cold and dry living environment, ultraviolet sunburn and other problems are all causes of damage to the skin barrier. The main causes of impaired skin barrier function are:

1. Long-term or excessive use of cosmetics and medicines containing hormones.

2. Long-term use of products with excessive levels of preservatives in flavors and colorants, as flavors and colorants are skin allergens.

3. Use of whitening and freckle removal products or products with excessive lead and mercury content.

Once the skin barrier is damaged, its protective ability decreases, and harmful substances enter the skin, causing inflammation and itching. The skin barrier function will further decrease, and scratching with hands will aggravate skin problems.

Skin barrier is a very important skin care knowledge, but it is not taken seriously and understood by users. As a result, many skin care scams appear. For example, certain soaps, certain creams, overnight whitening products, etc., which have skin-damaging ingredients, are sought after by users one after another. Little do they know that these are products that damage the skin, not products that care for the skin.
