How to determine whether you have stratum corneum

If the stratum corneum on the face is too thick, many skin problems will occur. It is necessary to exfoliate regularly. Some people are not sure when they should exfoliate. After all, frequent exfoliation is harmful.

How to tell if you have keratin

To see if there is keratin on your face, you can judge by observing the changes in skin color. Dull, rough and dull skin may be caused by too thick stratum corneum. If there are debris falling off the skin and acne easily occurs, it means that the stratum corneum of the skin is too thick and needs to be cleaned. If the skin care products used cannot be absorbed, it may also be that the aging keratin causes the skin care products to be absorbed slowly.

The role of the stratum corneum

The role of the stratum corneum is not only a mechanical protection, but also a physical protection, and also a chemical protection. The stratum corneum is the outermost layer of the skin and has a certain toughness, and can withstand mild scratching and friction. The stratum corneum on the palms and soles of the feet is the thickest, and can withstand relatively heavy impacts. The stratum corneum has elasticity and the combined effect of dermal fiber tissue and subcutaneous fat tissue can buffer external impacts and serious injuries, and play a protective role for subcutaneous blood vessels, nerves and other tissues. The stratum corneum also has a physical protection function. It is a poor conductor of electricity and heat, so it has a certain blocking ability for low voltage and low current. The resistance value is inversely proportional to the amount of water content in the stratum corneum. The stratum corneum plays a slow dispersion role for light irradiation, reducing the intensity of light entering the dermis, so this is also the reason why the skin is not sunburned. The keratinocytes in the stratum corneum and the intercellular substances have a certain barrier effect on chemical substances, so it is also a chemical protection. The hydrogen ion concentration on the surface of the skin has a certain buffering ability for acid and alkali substances. Exfoliation has both advantages and disadvantages. What you need to pay attention to is that you should not exfoliate too frequently. The skin layer is very thin, especially the skin on the face is more fragile. Frequent exfoliation will cause certain damage to the skin.

What are the benefits of exfoliation?

1. Promote skin absorption of skin care products

The old waste materials on the skin accumulate to form keratin, which causes the pores to be blocked and the skin cannot absorb skin care products. Exfoliation can quickly remove the excess keratin on the skin, thereby unblocking the pores and promoting the skin's absorption of skin care products.

2. Whitening

The keratin on the skin contains a lot of melanin, and the deposition of melanin will make the skin look dull and yellow, and some will even make the skin appear dark gray. The benefit of exfoliation is to remove the excess keratin on the surface of the skin, making the skin look much whiter.

3. Improve rough skin

Excess keratin attached to the skin will make it look very rough. Many girls always feel that the skin on their face is not smooth, which is because the exfoliation is not done well. The benefit of exfoliation is that it can make the skin smooth and remove the old dead skin on the surface of the skin.

4. Shrink pores

To shrink pores, use an exfoliating lotion with natural plant ingredients during the exfoliation process. It can not only dissolve aging cells on the surface of the skin, but also has a gentle friction effect, removing aging keratin, accumulated melanin and acne on the surface of the skin, thereby shrinking pores.

5. Prevent acne

On the basis of daily acne care, periodic exfoliation can help avoid acne outbreaks. For acne-prone skin, it is best to use a mild exfoliating product, such as an exfoliating product containing yeast ingredients, which can dissolve the dead cell tissue that clogs the pores.

6. Stimulate cell regeneration

It's normal for skin cells to renew at a slower rate, which means that old and dead cells are lingering on the surface of your skin. Removing these dead cells not only makes your skin smoother, but also stimulates the growth of new cells. Periodic exfoliation (two to three times a week) can achieve this. When you increase the rate of cell renewal, your complexion will become brighter and healthier.

Exfoliation minefield

Sensitive skin cannot be exfoliated. Exfoliating directly can easily wear out the skin. It is best to open the pores and soften the cuticles before exfoliating. The exfoliation cycle should be once a month, at least half a month. After exfoliation, be sure to pay attention to hydration and sun protection.
