Tear grass to keep moisture in! How to Improve Barrier Function


What is the barrier function?

It refers to the ability to stop foreign substances from entering the skin from the outside and to protect the skin’s moisture.

It prevents infection and disease caused by mites, dust mites, cell DNA damage from ultraviolet rays, chemical substances, bacteria, and viral infiltration. It also plays an important role in preventing water loss from the body and protecting healthy skin.

Three balances

That barrier function requires a balance of the following three factors.

◯sebaceous film

 It is a mixture of sebum secreted by the sebaceous glands and sweat secreted by the sweat glands.

 Too much or too little sebum can cause problems.

◯intercellular lipid

 A special lipid between the cells of the stratum corneum.

 These components, mainly ceramide and collagen, are used to neatly line up the stratum corneum and corneocytes.


◯NMF(Natural Moisturizing Factor)

It is an important substance located in stratum corneum cells and functions to enable the cells to retain moisture.

When these factors are in good balance, the moisture retention and barrier functions of the stratum corneum are realized, and the skin is kept healthy, fresh, and beautiful to the eye.

This helps to keep the skin healthy, fresh, and beautiful in appearance.

Skin problems due to reduced barrier function

So, what is the condition of the skin when the barrier function is impaired?

Causes of skin problems

Dry skin▶︎Loss of barrier function▶︎Itching▶︎Scratching

When the skin becomes dry, the barrier function becomes abnormal, causing irritation and allergic reactions. It also increases the risk of inflammation, itchiness, eczema, and dermatitis later in life. It can also lead to a loss of texture, poor turnover, and a worsening of the appearance of the skin.

Even though the skin may appear moist due to seemingly excessive sebum and perspiration, the interior of the skin is usually dry.

 After cleansing the skin, it is ideal to moisturize the skin immediately.

 Nercocia Astragalus skin care is rich in ingredients that promote the production of intercellular lipids, such as ceramides and cholestrol, which fill the spaces between corneocytes, leading to healthy skin.
