Some people say that skin will tell the story of your life. The problem is that this story is not always accurate. Why do some people look older and others look younger than their actual age? Why does the skin wrinkle? What makes our skin age? In response to these questions, plastic surgeon Rozina Ellie led us to find the answers about youth.

causes of wrinkles

with the increase of age, why do people's skin wrinkle? What is the reason for it

First of all, the epidermis, which constitutes the outermost layer of our skin, is a physical defense line to protect our body from external invasion. On average, every 6 days, people's bodies will produce a new layer of epidermis. The surface cells of the skin constantly rub and fall off, thus being replaced by the new epidermis at the lower level. With the increase of age, the longer the self-renewal time of epidermis.

The second is dermis, which is absolutely critical in the aging process, and contains collagen and elastic fibers, which can ensure the elasticity and wrinkle-free of young skin. With the increase of age, the amount of collagen and elastic fiber in human dermis is decreasing, and the fat under skin tissue is also decreasing. Therefore, the skin will become more and more inelastic, start to sag, and slowly show signs of wrinkles.

Collagen and fibroblasts are very important. Collagen gives skin strength and elasticity, and it forms a complete three-dimensional fiber network. Before the age of 4, people's bodies will produce a lot of collagen, but since then, the amount has begun to decline. Fibroblasts are collagen production machines. In young skin, they pull collagen tightly to prevent sagging skin. However, with the aging of the body, their ability to produce collagen is declining, and the relationship between fibroblasts and collagen begins to break down. As a result, more and more wrinkles appear and become deeper and deeper.

UV protection

Plastic surgeons think that we should pay attention to how to protect our skin from UV protection, diet and prevention. Most of us know the harm of sunburn, but this is just one of the harms that the sun brings to our skin. Sunlight contains different types of ultraviolet rays, the difference lies in the wavelength difference. Sunburn is caused by UVB ultraviolet rays. These ultraviolet rays have a short wavelength, which means that they can burn the outermost layer of the skin, but they cannot penetrate deeper. UVA ultraviolet rays have a longer wavelength and can penetrate deep into the skin. UVA ultraviolet rays can decompose collagen, which leads to wrinkles on the skin.

therefore, the simplest way to protect the skin is to prevent ultraviolet rays from the sun. This kind of protection doesn't just mean that you need protection when you are outdoors in the sun, because UVA ultraviolet rays have a longer wavelength and can penetrate glass, so it is possible to accelerate skin aging when driving on the road or sitting by the window.

correct diet

Plastic surgeons also believe that proper diet is also one of the important ways to protect the skin. Because when we breathe, there is always a small amount of oxygen entering cells and attacking DNA. These oxygen molecules are called free radicals. The damage they bring, especially to the fibroblasts responsible for collagen formation in the skin, will accumulate over time. Therefore, this will also lead to wrinkles.

However, we always have to breathe, and it is impossible to protect our skin without killing ourselves. So, how to have your cake and eat it? Plastic surgeons believe that proper diet can reduce the damage caused by free radicals, and give several key guiding suggestions-< P > Principle 1: Bright color. For example, tomatoes are an important source of lycopene, which is a powerful antioxidant. Lycopene makes the red color of tomatoes look brighter, and it is very effective in preventing oxidative stress, which will lead to accelerated aging.

principle 2: bitter fruits and vegetables. Broccoli and radish are rich in glucosinolates, which are also antioxidants.

principle 3: eat more fatty fish. This fish contains a key ingredient, namely Omega-3 fatty acids. This fatty acid can inhibit inflammation of skin cells and help slow down oxidative stress.

principle 4: some bad living habits will also accelerate skin aging, such as smoking.

Pay attention to blood sugar

By studying the relationship between blood sugar and skin aging, scientists found that people with high blood sugar look 2 years older than their actual age. Because the excess sugar in the blood will attach to the collagen in the skin. Once attached, it will cause collagen to be easily destroyed, and it is difficult to help the skin repair itself, so the result is more and more wrinkles. Blood sugar is produced in the process of food digestion. Normal exercise and reducing the consumption of sugary foods can effectively avoid high blood sugar, thus playing a role in preventing skin aging.
