What beauty methods can't be used at will?
(1) "Blood washing" to lose weight: the so-called "blood washing" is commonly known as hemodialysis therapy. It is originally a treatment method, and the indications need to be strictly controlled.

In recent years, with the improvement of people's living standards and the change of diet structure, the number of patients with hyperlipidemia has increased significantly. Some people hope to lose weight and beautify themselves with the help of "blood washing". Because "blood washing" is to filter macromolecules in blood, while removing "blood garbage", protein, amino acids, zinc, selenium and other substances necessary for human body are also removed from the body.

Therefore, if "blood washing" is too fierce, it will cause a sharp drop in plasma osmotic pressure, brain edema, myocardial cell edema, arrhythmia, cardiac conduction block and other complications in the short term, and bone pain, dizziness, dry skin, nail deformation and other complications in the long term. So use it with caution.

(2) Nano-beauty: Recently, "nano-beauty products" have been listed frequently, which has attracted the attention of the beauty industry. But according to experts, most of these so-called "nano-beauty products" are unqualified products. Many of these products contain silicon oxide, titanium oxide, manganese oxide or silver, which will "float like ghosts" in the human body. If they lurk in cells, they may induce cytopathic effects and lead to cancer.

(3) Skin dyeing: A research report shows that bronzing the skin may increase the risk of skin cancer. According to the report, people who dye their skin bronzed are more than twice as likely to be bronzed as ordinary people, because the substances used for dyeing can't replace the role of sunlight, and dyeing can't protect them from sunlight radiation, but it will enhance their absorption of sunlight.

In addition, people who dye their skin bronzed will have the idea that if the skin is not white, there is no need for sun protection; And because their skin is beautiful bronze, they are more willing to show their bodies in the sun than ordinary people. In this way, they are naturally more likely to get skin cancer than the average person.

(4) Quick freckle removal: Spot marks are medically called damaging skin diseases, and plant masks are generally used. The time, formula and course of treatment vary from person to person, and most of them can be effectively removed or alleviated, but it is impossible to cure 100%. The shortest freckle removal time is 30 days, which is the necessary time for the natural metabolism and shedding of the original skin pigment.

(5) liposuction to lose weight: liposuction to lose weight, the effect is "immediate". During the operation, it is necessary to open a small hole at the liposuction site. The biggest risk of liposuction is the most prone to fat blockage, that is, broken fat particles enter blood vessels, block blood circulation, lead to ischemic necrosis, and even endanger life, so liposuction must be carried out in regular hospitals.

(6) Injection breast augmentation: Because the operation of injection breast augmentation is simple, many beauty salons are very enthusiastic. There are two ways to inject breast augmentation: one is foreign body injection, that is, injecting polymer into the chest. This method is not advisable, because the injected foreign body will make the surrounding tissues fibrotic. Another way is breast augmentation with autologous tissue. Autologous tissue can be divided into muscle breast augmentation and fat tissue breast augmentation, with the advantage of reliable materials. Muscle filling is not easy to produce rejection, but it is difficult to connect blood vessels and nerves and it is not easy to succeed. Filling with fat is relatively simple. Liposuction was used to remove fat first, and then injected into chest cavity after treatment. The disadvantage is that the effect was considerable at that time, but the injected fat was easily absorbed after a long time.
