Explain the basics of dermatology. In life, we have all encountered skin problems to some extent. When we encounter skin problems, how should we solve them? First of all, you need to know the basic knowledge of dermatology in order to know where your skin problems are and prescribe the right medicine.

Explain the basic knowledge of dermatology 1 1. Epidermis: Epidermis contains stratum corneum -6- 10 layer of flat keratinocytes (visible to the naked eye).

Transparent layer-only on the soles of the feet and palms, which plays the role of heat insulation and wear resistance.

Granular layer-arranged like a product, containing keratin-like, which can refract light.

Spiny layer-the thickest layer of epidermis, which absorbs and transports nutrients.

Basal layer-the biochemical layer of dividing and reproducing cells

Second, the dermis: contains collagen and elastic fibers (related to skin aging).

Third, subcutaneous tissue: fat

4, stratum corneum: layered like a fish scale to prevent water loss, keratinocytes have no life, also known as dead skin cells.

Its function is to keep moisture.

5. Too thin stratum corneum will lead to water loss, dry and tight skin, and it is necessary to give enough water. Too thick stratum corneum will make the skin lose its sense of permeability, rough and dull, and hinder the absorption of nutrients.

Basic knowledge of dermatology 2 How to solve the problems of skin water shortage and makeup?

1, skin moisturizing work should be done well.

First, let's look at the seasons. In spring and autumn, the skin is easy to be dry and dehydrated, and even chapped. These are all problems that are easy to occur in the dry season. Therefore, in autumn, what we need to do most is to moisturize and hydrate the skin. Only when the moisturizing and hydrating work is done well can we really solve the problem of difficult makeup.

Girls can solve the problem of skin water shortage by drinking more water, eating more fruits and vegetables, applying more moisturizing masks and spraying more moisturizing sprays. Many girls will ignore this point, so the makeup will fall off and float on the surface of facial skin, and the real makeup effect will not be achieved. Moisturizing and hydrating the skin is a very important first step.

Step 2 make up with a sponge

After ensuring the very important moisturizing and hydrating work, start putting on makeup. For make-up, girls should master the methods. Here I suggest that it is better to use a sponge to make up. Apply a proper amount of liquid foundation to your face with your fingers, first spread it, and then evenly spread it with a sponge. Finally, girls can sprinkle a layer of transparent loose powder and brush it evenly with a soft brush, so that the makeup on their faces will look more natural.

Step 3 Moisturize after makeup

Because our skin is full of water, our makeup won't come off. If our skin is dry, good cosmetics will fall off. Therefore, it is very important to ensure that our makeup is moisturizing. Girls can do this: after washing their faces, wipe off the moisture on their faces, then apply toner and pat gently to let the skin absorb the moisture, then apply lotion and pat gently to let the skin absorb the nutrients in the lotion, and finally put on makeup, and don't let the interval between the two be too long, which will make the makeup less likely to fall off. In addition, it should be noted that good makeup should be replenished with moisturizing water every few hours to consolidate makeup!

4, eye and lip moisturizing can not be ignored

When the weather is dry, our eyes are easy to dry and our lips are easy to crack and peel. If we wear eye makeup, our eyes still look dry, lipstick is applied, and our lips are still dry, it will be bad. Therefore, we should pay attention to the moisturizing work of the eyes and lips to moisturize the lips. Girls can drink plenty of water and apply lip balm at any time to moisten their lips. Eye moisturizing, girls can gently pat their eyes with moisturizing water to make them fresher, bid farewell to dryness and make their makeup more relaxed and moist.
