Basic knowledge of beauty 1 Understanding skin: skin has elasticity and protective effect. Under normal circumstances, metabolism promotes skin rejuvenation.

Skin can be divided into three layers from outside to inside, namely epidermis, epidermis and subcutaneous tissue. In addition, there are some auxiliary organs in the skin (sebaceous glands, sweat glands, hair and nails).

Epidermis is the outer layer of skin, covering the whole body and having protective effect. The average thickness of epidermis is 0. 1 to 0. 3mm. There are no blood vessels in the epidermis, but there are many tiny nerve endings, which can sense the stinging of the outside world and produce feelings such as touch, pain, cold, heat and pressure. Located in the deep layer of epidermis, it is connected with skin tissue downwards, and consists of dense connective tissue, in which various connective tissue cells and a large number of collagen fibers are distributed, making the skin both elastic and tough. Located between epidermis and subcutaneous tissue, it is mainly composed of connective tissues such as collagen fibers, elastic fibers, reticular fibers and amorphous matrix, including nerves and nerve endings, blood vessels, lymphatic vessels, muscles and skin accessories.

Several common skin types

Neutral skin: It can be said to be very good skin, which is more common in adolescent girls. The sebum secretion is moderate, the skin is dry and oily, the skin is ruddy and delicate, elastic, with small pores and insensitive to external stimuli.

Dry skin: fair skin with small and inconspicuous pores. Less sebum secretion, dry skin, easy to produce fine lines and pigment.

Oily skin: dark complexion, large pores, more sebum secretion, greasy and shiny skin, not easy to wrinkle, insensitive to external stimuli. Because of excessive sebum secretion, it is easy to grow acne.

Mixed skin: Mixed skin is a kind of skin with two states: dry mixed skin and oily mixed skin. T-zone is mostly oily, with dry cheeks and sometimes acne.

Apply make-up water before applying the mask, because make-up water (toner/toner) can play a good guiding role, so that the nutrients in the mask can be continuously injected into the skin. If you don't use lotion in advance, the mask will enter the pores for a longer time, and the absorption effect will be greatly reduced. If you are not careful, you will waste enough nutrients in the mask.

Improper yellow-faced woman, take a look at 1 before going to bed, and thoroughly clean the skin before going to bed-overnight makeup is the culprit of dark yellow skin; 2, cotton pad with makeup water to wipe the face-secondary deep cleaning to solve the skin; 3, moisturizing products must not be forgotten-skin water shortage is an important reason for dark yellow; 4.

These water-based moisturizing ingredients are lost by the washing power of water, and the moisturizing effect is weakened. Or you can choose some masks with oily ingredients, so that there will be no dilemma of moisturizing ingredients after washing.

Basic knowledge of beauty 3 I. Texture and structure of skin

Skin can be divided into three layers: epidermis, dermis and subcutaneous tissue.

● The thickest places are palms and soles.

● The thinnest is the eyelid.

□ Functions of epidermis and dermis

● The epidermis has the function of self-repair.

● Once the dermis is injured, it will be difficult to heal and leave scars.

1, epidermis

The epidermis is the thinnest cortex, and the facial epidermis consists of four layers, from outside to inside:

● stratum corneum

● Granular layer

● There are thorns.

● Basic layer

(1) epidermal basal layer

Basal layer: composed of basal cells and melanocytes, only 1 layer. It can produce melanin and protect the skin from ultraviolet rays. Cells have the ability to divide and proliferate.

(2) The epidermis has spinous layer.

Spiny layer: It is composed of spiny cells, accounting for most of the epidermis, and its main function is to transport nutrients.

(3) epidermal granular layer

Granular layer: composed of granular cells, it is the surface defense zone of skin. At this point, the cells have begun to age gradually.

(4) Epidermal stratum corneum

Cuticle: It is composed of 5- 10 layers of dead seedless keratinocytes, with a scaly structure and strong water absorption. It has an effect on metabolism. It can prevent water loss and infiltration. Strong friction resistance, can resist slight stimulation, and will fall off on its own.

Low water face.

The water content and oil content of stratum corneum are related to the beauty of face.

○ Water content accounts for 10-20%

○ Oil content accounts for 5-7%

When the water content of the face is less than the water content, fine lines will appear, but they can be eliminated by hydrating and moisturizing.

2. Leather

Dermal is 0/5 ~ 40 times larger than epidermis, and consists of collagen fibers and elastic fibers. The dermis contains hair follicles, hairy muscles, sebaceous glands, sweat glands and other accessory organs.

● Fibrous tissue of dermis.

(1) Collagen fiber-the main component of dermal tissue, which is thick and composed of collagen and arranged horizontally in bundles. Toughness and tensile strength, but lack of elasticity.

(2) Elastic fiber-a component of dermal tissue. The fibers are very thin, composed of elastin, and wound between collagen fibers in a wave shape. Elastic fibers make the skin elastic and can be restored to its original state after stretching.

3, subcutaneous tissue

Below the dermis is subcutaneous tissue, also known as subcutaneous fat layer, which contains sweat glands, hair balls, nerves, blood vessels and other ancillary organs.

Fat can protect the body, has the function of heat insulation and heat avoidance, and the amount of fat content is bound to make people slim and plump.

Men's body fat content accounts for 15-20% of body weight, while women's body fat content accounts for about 20-25%, so women are more hardy than men.

Second, the physiological function of the skin

1, protection function

2. Sensory function

Step 3 Adjust the function

4. Secretion and excretion function

5. Immune function

6, absorption function

7. Metabolic function

Third, the growth cycle of the skin

●0~ 16 years old-growing period

● 16~20 years old-maturity

● After the age of 20-tend to be aging.

The growth cycle of skin is not necessarily based on age, but will be advanced or postponed according to various factors such as heredity, environment, region, spirit, nutrition, physiology or pathology, maintenance and so on.

□ The story of age

(1) AD age (actual age)

(2) Emotional age (extroverts are young and depressed people are old)

(3) Age modification (people who pay attention to facial maintenance and figure maintenance are young, while "yellow-faced woman" and "beer barrel" are old)

(4) Physiological age (young people with normal endocrine and regular diet)

□ skin aging cycle and characteristics after 20 years old

(1)20-25 years old: dry skin with laugh lines at the corners of the eyes and fine lines on the forehead and corners of the eyes;

(2)25-35 years old: wrinkles begin to appear around the lips, and crow's feet appear in the corners of the eyes;

(3)35-45 years old: the mandibular skin is loose, with spots and obvious wrinkles;

(4)45-55 years old: the skin is quite dry, wrinkles are obviously increased, pigmentation is also increased, and senile plaques appear;

(5) After the age of 55: the skin is rough, dry and slack, eyes droop, wrinkles and deep spots, and the characteristics of the elderly are obvious.

Proper maintenance and comprehensive conditioning can make facial skin 5- 10 years younger than the actual age.

Fourth, the metabolism of the skin

1. Metabolism: The whole process from cell growth to aging, death and shedding is called metabolism, and the cycle is 2 1-28 days.

2, the performance of metabolism

(1) Normal metabolism: the skin surface is soft, smooth and fine.

(2) Abnormal metabolism: The skin looks rough, dry and pigmented, and it is easy to get facial sores.

Fifth, the protective film of skin-sebum film

Sebum membrane: Sebum secreted by sebaceous glands and sweat secreted by sweat glands are mixed on the skin surface to form a milky lipid membrane called sebum membrane. It has a certain protective effect on the skin.

Six, skin pH-pH value

In medicine and cosmetology, the pH value of skin is usually used to judge whether the skin is healthy or not.

Skin PH value

Normal skin 4.8-5.6

Partial dry skin 4.0-5.0

Oily skin 5,6-6,6
