The skin does not absorb skin care products, then my white silver.

The stratum corneum of healthy skin is a dense brick wall structure, which is an effective protective system for the dermis and other subcutaneous tissues, preventing most external skin from threatening to invade important tissues of the human body.

Look at the tight sample of the stratum corneum.

Just dense, brick walls, these two words appear to be very "defensive", so that most people who are new to popular science have questioned their skin care products.

When we learned that the simple toner and moisturizer were all on the surface and dried naturally rather than absorbed by the skin, did the little black and little red bottles in the hand lose their meaning in an instant?

The money was wasted.

The absorption function of the skin is also part of its function.

Although our skin does not breathe as well as amphibians like frogs, it does have absorptive properties.

To take a more extreme example, the assassination links that often occur in spy movies take advantage of the "percutaneous absorption" of the skin, and when the skin comes into contact with enough deadly substances such as potassium cyanide, they will die.

Skin absorption function is also an important part of skin function, but the absorption capacity of the skin itself is limited, not everything on the face can be absorbed by the skin.

Does limited absorption mean it's useless?

Although we have understood the absorption function of the skin, the small amount of absorption is not equal to meaningless.

No, most of the substances that act on the skin and work are trace elements, such as anti-aging and antioxidants, which only need a small amount to work. Don't consider skin care products to be IQ tax just because they absorb less.

In addition, we just mentioned simple moisturizing, sunscreen and other skin care products, most do not need the absorption function of the skin to play a role, only need to stay on the surface.

There are some ingredients, skin care methods do not need to be absorbed into the deep layer of the skin can have an impact on the deep layer of the skin.

For example, fruit acid-as a common anti-aging substance, it only stays in the epidermis, but with its use, it will also have an impact on the dermis, making the dermis thicker, collagen increased and other effects, so as to achieve the purpose of anti-aging. The same phenomenon will also appear in medical beauty methods such as photon rejuvenation. It's called fighting cattle across the mountain, but that's all.

If you think that "skin absorption is skin care"

These are probably students who need to make up lessons.

Ask other students to supervise on a daily basis

How to enhance the absorption function of the skin

With the development of modern skin care products, many ways to promote penetration have been derived:

For example, the mask "Please use the mask in the medical field, not recommended daily use"; fruit acid skin, appropriate exfoliation; microneedle, soluble microneedle, can achieve the purpose of promoting penetration.

Of course, we see that these ways of promoting infiltration are carried out around the stratum corneum or around the stratum corneum.

In daily life, we do not recommend to operate these ways of promoting osmosis on our own, especially for patients with skin problems. Without the operation of a professional doctor, the skin will only be exposed to greater risk.

I am very happy to tell you that the money has not been wasted.

But please read after me before that.

Moderate cleaning-reasonable moisturizing-strengthening sunscreen

If you fail to do so, the investment in skin care in reasonable science will also become an IQ tax.
