Why is the skin loose?

80% of human skin is collagen, and generally after the age of 25, the human body will enter the peak period of collagen loss. And when the age reaches 40, the collagen in the skin will be in a precipitous loss period, and its collagen content may be less than half of that at the age of 18.

1. Loss of protein in the dermis:

Collagen and elastin, which support the skin and make it plump and firm. After the age of 25, these two proteins naturally decrease due to the aging process of the human body, and then make the skin lose elasticity; In the process of collagen loss, the collagen peptide bonds and elastic network supporting the skin will be broken, resulting in the symptoms of skin tissue oxidation, atrophy, and even collapse, and the skin will become loose.

2. The supporting force of skin decreases:

Fat and muscle are the biggest support of skin, while the loss of subcutaneous fat and muscle relaxation caused by various reasons such as aging and lack of exercise make the skin lose support and sag.

3. Endogenous and exogenous:

Skin aging is caused by both endogenous and exogenous aging. The aging process leads to the decline of skin structural integrity and physiological function. Endogenous aging is mainly determined by genes, and is irreversible, and is also related to free radicals, glycosylation, endocrine, etc. After aging, skin adipose tissue loss, skin thinning, and collagen and hyaluronic acid synthesis rate are lower than the loss rate, resulting in atrophic skin loss of elasticity and sagging. The extrinsic aging of wrinkles is mainly caused by sunlight, which is also related to smoking, environmental pollution, wrong skin care, gravity, and so on.

4. UV:

80% of facial aging is caused by sunlight. UV damage to the skin is a cumulative process, following the frequency, duration and intensity of exposure to the sun, as well as the skin protection of its own pigment. Although the skin will activate the self-protection mechanism when it is damaged by UV. Activate the melanocytes in the basal layer to synthesize a large amount of black and transport it to the surface of the skin to absorb ultraviolet rays, reduce the damage of ultraviolet rays, but some ultraviolet rays will still penetrate the dermis, destroy the collagen mechanism, hyaluronic acid loss, elastic fiber atrophy, and a large number of free radicals, resulting in suntan, relaxation, dry and rough skin, and deep muscle wrinkles. So sunscreen must be done all year round.

5. Other factors:

For example, gravity, heredity, mental stress, exposure to sunlight and smoking also transform the skin structure, and finally make the skin lose its elasticity, resulting in relaxation.

Summary:

Skin aging is caused by multiple factors. In terms of management, we need to start with the skin state and aging reasons, and scientifically customize the management. Once true wrinkles are produced, it is difficult for general skin care products to effectively remove them. Most of them need to be combined with the management of beauty equipment to act on the dermis to achieve wrinkle removal effect, such as MTS mesoderm therapy, radio frequency, water light needle, laser, fat filling, botulinum toxin, etc.
