Is exfoliation and rubbing the bath the same thing?

Rubbing and exfoliating are definitely not the same thing.

Exfoliation generally refers to the greasy skin on the face, unbalanced diet, disordered life, frequent staying up late, smoking and drinking, affecting the metabolic rate, and the keratinocytes on the face cannot fall off naturally. Exfoliation is achieved through salt, orange peel, scrub and other items.

Rubbing refers to wiping off the dirt on the whole body skin with a towel or a bath towel to make the skin cleaner and fresher. Although both can exfoliate, they are not the same thing.

Extended data:

I. Brief introduction of rubbings:

Cells in the stratum corneum contain keratin. It helps to reduce water evaporation and even absorb water to keep skin moist. The stratum corneum is generally between 10 and 40 microns. Excessive removal of the stratum corneum will cause the stratum corneum to become very thin, the skin will be more sensitive, and serious red blood will appear.

The skin surface is a stratum corneum composed of completely keratinized keratinocytes. Keratinocytes are constantly differentiated from basal cells and gradually migrate to the stratum corneum through the spinous layer and granular layer. They are flat and seedless, and constantly disintegrate and fall off, forming so-called "dander".

The time of this evolutionary process is called epidermal growth cycle, which takes about 3 ~ 4 weeks, and is also called epidermal renewal rate. The stratum corneum is isomorphic to the lipid film on the epidermis formed by emulsification of sebum and water on its surface, forming the outermost barrier protection layer of the skin, which plays a very important role.

On the one hand, it protects all kinds of tissues and organs in the body from all kinds of damage from the external environment, such as mechanical damage such as friction, pulling, squeezing and collision, physical damage such as electric shock, light and magnetic sound, and chemical damage such as acid and alkali corrosion, especially the dense stratum corneum can effectively prevent bacteria and viruses with a diameter exceeding 200nm from entering the skin;

In addition, the free fatty acids in the lipid membrane on the skin surface make the pH value of the skin surface acidic, which inhibits the growth of many bacteria, thus protecting the body from microbial invasion. On the other hand, the semi-permeable membrane of stratum corneum can well prevent the loss of nutrients in the body. Adults lose about 240 ~ 480 ml of water through the skin every day, but if the cuticle is removed, the water loss will increase by more than 10 times.

It can be seen that when we take a bath, scrubbing the skin with a rubbing towel too hard will often make the keratinocytes that have not been completely keratinized fall off prematurely, or even the cuticle completely fall off, exposing the bright red granular layer or spinous layer skin, which greatly weakens the barrier protection of the skin, and the body is easily damaged by the external environment, and in the long run, it is easy to accelerate the aging of the skin, so it is best not to use too much force when taking a bath.

Second, an introduction to exfoliation:

Modern people often slow down their metabolism due to poor contact with external environmental conditions, unbalanced diet, abnormal work and rest, staying up late, smoking, drinking, mood and other factors. Abnormal metabolism prevents keratinocytes from falling off naturally and accumulating on the surface thickly, resulting in rough and dull skin.

Skin care products are often blocked by this thick barrier and cannot be absorbed by living cells below. Therefore, it is necessary to prevent keratin thickening. The surface layer of skin is metabolized once a week, and too much old waste keratin accumulates on the skin, which will cause skin burden. Therefore, exfoliation is used to remove the dead horniness on the skin surface and let the skin breathe again.
