Protect the skin barrier through three lines of defense"},"content":{"rendered":"\n

<\/p>\n\n\n\n

If the skin is compared to a castle, if Mario wants to go to the core of the palace to find the princess, he must go through three security checkpoints.<\/p>\n\n\n\n

These three levels are the three layers of barriers of the skin.<\/p>\n\n\n\n

<\/p>\n\n\n\n

3 layers of skin barrier<\/h3>\n\n\n\n

The outermost layer is an invisible barrier, which is the beneficial bacteria on the skin surface and the first line of defense against foreign enemies (bacteria).<\/p>\n\n\n\n

The stratum corneum needs the help of good bacteria (probiotics) to fight against harmful bacteria. If there are more bad bacteria than good bacteria, this line of defense is destroyed.<\/p>\n\n\n\n

On the contrary, if the barrier measures are sufficient, no harmful bacteria will enter the skin, and the chance of skin sensitivity will be greatly reduced.<\/p>\n\n\n\n

<\/p>\n\n\n\n

The second level is the lipid layer.<\/p>\n\n\n\n

Enough Omega 2, squalene and fatty acids must be deployed here to form a stable sebum film. Lipids must be replenished every day so that they will not be lost and keep stable.<\/p>\n\n\n\n

<\/p>\n\n\n\n

The third level is the water layer.<\/p>\n\n\n\n

It is safest and most effective to have an endless supply of adsorbable water-soluble substances, such as vitamin B3, vitamin B5, hyaluronic acid, amino acids, urea, sodium PCA and other natural moisturizing factors.<\/p>\n\n\n\n

If any level is not strong enough, it means the skin barrier is damaged. The skin’s overall defense or combat effectiveness will become fragile.<\/p>\n\n\n\n

<\/p>\n\n\n\n

What are the symptoms of abnormal skin barrier?<\/strong>
– dry
– Get rid of skin
– Sensitive
– Tingling
– reddish
– Inflammation
– Recurrent acne or pimples
– thinning of skin
– no luster
– Particularly sensitive to environmental changes, such as excessive dust, poor air quality, exposure to the sun, etc., which may cause itching easily<\/p>\n\n\n\n

<\/p>\n\n\n\n

Will the skin barrier be damaged?<\/strong><\/p>\n\n\n\n

In fact, most sensitive skin is acquired due to excessive cleansing or exfoliation. In fact, washing your face in the morning and evening is enough. If you don\u2019t exfoliate every day, it will be very difficult to wash away the good bacteria on the sun-exposed face, and harmful bacteria can easily invade the skin!<\/p>\n\n\n\n

By the way, many people are surprised that if they don\u2019t use fruit acid (AHA) or salicylic acid (BHA) to exfoliate at all, will it destroy the skin barrier?
In fact, it is not the case. As long as you pay attention to the concentration, good home-formulated fruit acid or salicylic acid products will only remove old dead skin cells and will not thin the skin barrier. Unless you go to a beauty salon and use a higher concentration than home-made formulas, there is a chance that the skin barrier will be weakened.<\/p>\n\n\n\n

There are also some acquired factors that can cause damage to the skin barrier:<\/strong>
– Use irritating cosmetics and skin care products, not CLEAN BEAUTY products, as the chemical ingredients can easily irritate the skin.
– There is no need to repair the skin after the medical treatment.
– Doing LASER with too high intensity and too many repetitions
– Abuse of steroid creams<\/p>\n\n\n\n

<\/p>\n\n\n\n

What if the skin is really sensitive and the barrier is damaged all the time? What can be done to improve it?<\/strong><\/p>\n\n\n\n

Recognize these skin care ingredients that can soothe, moisturize, and repair the barrier<\/p>\n\n\n\n

1. Ceramides (ceramides) human body\u2019s natural lipids<\/p>\n\n\n\n

2. Omega fatty acids
Omega fatty acids are very useful fats whether eaten or applied on the skin. There are eleven types of Omega fatty acids currently known, of which Omega-3 and Omega-6 are essential fatty acids because our bodies cannot produce these two components on their own.<\/p>\n\n\n\n

3. Hyaluronic acid
That is hyaluronic acid, a mucopolysaccharide component that helps the body retain water.<\/p>\n\n\n\n

4. Zinc
Both skin care products and sunscreen contain this ingredient. It is very important to protect the skin barrier with sunscreen. Use SPF 30 or above to have a moisturizing effect and protect against UVA and UVB.<\/p>\n\n\n\n
