The skin is the largest organ of the human body, and it performs the function of protecting the body, wicking away sweat, feeling hot and cold, and stressing. Therefore, the skin that covers the whole body of the human body has become the "first line of defense" of the human body. When various "hostile forces" intrude from the outside world, the skin bears the brunt of it, being both the first and the first victim. If the invasion of the outside world is too sudden and violent, the skin will be excessively damaged. Regarding the skin, it is recorded in the Yellow Emperor's Inner Classic that women begin to show signs of aging from the age of 35, and women's skin aging will accelerate after the age of 42. #皮肤 #
From infants and young children growing into beautiful girls, from mature young women to old people with late faces, women's skin has been following the footsteps of the years and undergoing tremendous changes. Due to the thickness of the skin, the function of the stratum corneum, and the secretion of sebaceous glands and sweat glands, the skin has always shown different physiological secrets throughout a woman's life.
The thickness of the cuticle of the skin in infancy is 30% thinner than that of adults, the epidermis layer is 20% to 30% thinner than that of adults, and the total thickness of the dermis of infant skin is also lower than that of adults. Infant skin has much less melanin synthesis than adults, although the density of melanocytes in infant skin is similar to that of adults. The proportion of granular layers and spinous cell layers in the epidermis layer of infant skin is relatively lower than that of adults, making infants' cell renewal rate faster than adults. Therefore, if the same injury is suffered, the wound healing ability of infant skin is much stronger than that of adult skin wound healing.
After entering puberty, the functions of the girl's body also enter the rapid stage of growth and development, and the skin is also changing at this time. As estrogen increases, the skin appears exceptionally soft, smooth and elastic. However, due to the strong secretion of sebaceous glands in the skin during adolescence, women's skin is prone to some skin inflammation in the adolescent stage: acne, eczema, etc., affecting the health and appearance of the skin.
As women age, the metabolism of the body slows down and a series of changes occur in the skin. The replacement time of keratinocytes in the epidermis of the skin is prolonged, and the content of natural moisturizing factors and ceramides in the skin decreases. The regeneration of collagen fibers in the dermis is not obvious, and the content of hyaluronic acid decreases. These can all lead to a decrease in the moisture content of the skin and the skin to become dry. Wrinkles begin to appear in certain parts of the face, such as the corners of the eyes, forehead, etc. As a result of cumulative photodamage, signs of photoaging occur at the exposed site (eg, face, extensor side of the extremities), including thickening of the stratum corneum, dry skin, and irregular pigment spots. There is less collagen in the skin, less hyaluronic acid, and the skin is not as elastic as it used to be. Especially in women during pregnancy and menopause, due to the rapid increase or decrease of hormones in the body, skin changes will be more obvious.
After entering the old age, the decline of the woman's skin worse and worse, began to become soft, thinned, atrophied, dry, wound healing was slow, no elasticity, and the barrier protection function of the skin plummeted. On the face, neck, chest and limbs, the skin is prone to deep and coarse wrinkles and local hyperpigmentation. Skin atrophy in older women affects not only the epidermis, but also the dermis and subcutaneous tissues. Since the dermis is the main scaffold of the skin, the atrophy of dermal fibers causes many tissues in the dermis to lose their support, and the blood vessels are prone to breakage and bleeding after lack of support, and the contraction and relaxation function of blood vessels is also disturbed. This is also the reason why the skin of the elderly is prone to purpura and easy to get cold.
In addition to aging with age, a woman's skin also has a metabolic renewal cycle. The metabolic renewal cycle of healthy skin is generally 28 days. During this cycle, the skin will constantly shed dead skin, allowing the nascent and youthful cells in the inner layer to reveal the surface layer. After removing the dead skin, the skin will appear delicate and radiant. However, the skin's renewal cycle can also be greatly slowed down by age or frequent exposure to environments that are not good for the skin, becoming rough and yellowish, and other skin problems can also occur.
Men pursue a woman, not only value her face, body, many times, beautiful skin also accounts for a large part. A woman's skin is also a specific instruction manual for women's cultivation, quality of life and personal temperament. Women's care for the skin is no longer just a matter of retaining youth and maintaining radiance.
Because smooth, delicate, smooth, elastic skin can visually convey beauty, kindness and pleasure, rough, gray, pigmented and uneven skin gives people more negative feelings, and even easy to make people feel distance and rejection. Therefore, women who love beauty, to be beautiful, must first start by caring for their skin.
True skin care is divided into two aspects: care and maintenance, care and maintenance angles are different, care is heavy on the outside, maintenance is heavy on the inside. Care needs to grasp several major links such as sun protection, cleaning, skin movement, and cosmetic use. On the basis of nursing, by mastering the correct maintenance methods, you can effectively raise your own skin.
