What’s skin barrier damaged?

One of the major discoveries of the global skin immunology in 2011: When the epidermis is intact, the commensal bacteria such as bacteria, fungi or viruses on the skin surface are not directly pathogenic. Once the epidermis is damaged (ie, the skin barrier is damaged), these symbionts will Into the dermis and trigger immune inflammatory response.
A variety of skin diseases, many skin diseases prone to recurrent, but difficult to find a specific cause of the disease. Common skin redness, itching, dry hair and other “allergic skin” performance, it is actually difficult to find a specific “allergens.” However, there is one common reason these skin diseases can find – “skin barrier damage”, that is, the surface of the skin loses its normal protective function and there is a loss of skin moisture, resulting in dry skin, scaling or itching; at the same time, Germs on the surface of the skin easily pass through the damaged skin barrier and enter the interior of the skin, thereby further triggering skin inflammatory reactions. Therefore, the damage to the skin barrier is not only the performance of many skin diseases, but also may be an important cause of repeated attacks of skin diseases.

1.Cuticle barrier function impaired and repair schematic

Damaged and Complete epidermal tissue

2.Skin barrier function damaged.

Damaged skin barrier fuction

1).Skin moisture evaporates too much.

2).Skin is contaminated with bacteria.

3).Skin is contaminated with chemicals.

4).Dull skin.

5).Skin self-protection is weakened.

Good skin barrier fuction

1)Skin stays moist for a long time

2)Sskin can resist outside invasion

3)Skin is shiny and elastic

3.Factors that damage the skin barrier

4.Producing Mechanism

Mainly because of the skin barrier function damged

5. Sensitive skin non-invasive skin test

Tip: sensitive skin moisture content and fat were lower than the normal control group, there was a significant difference, while the skin elasticity between the two no significant difference.

From the data analysis: the sensitivity of the skin moisture content and lipid content of the normalization, can effectively reduce the skin sensitivity

6.Cases

Using external acne medicine makes skin sensitive

Hormone dependent dermatitis.Skin thinning, telangiectasia, sensitive.

Skin alergy after whitening and laser

7.Dry scaling, skin itching is the basic symptoms of dermatitis eczema? Moisturizing, relieving itching is the first choice for the treatment of dermatitis eczema.
