Part I What determines our skin color?
Why do people in the world have different skin colors? What determines the color of our skin? Let’s unravel the mystery of skin color together.
The color of skin is mainly determined by melanin, methemoglobin, carotenoids and so on. The main factor that determines the shade of skin is melanin, which is related to its quantity and size, and usually the method of skin whitening is mostly to destroy p less melanin. Melanocytes are mainly found in the skin, hair and eyes, and the number of melanocytes decreases with age, and is more obvious in areas covered by clothing, but not in areas of the face and hands that are often exposed to sunlight. Melanocytes are associated with the skin’s ability to resist ultraviolet light from sunlight. Melanocytes transport the melanin granules they produce into the keratinocytes on the surface of the skin. When exposed to sunlight, melanin granules gather on top of the keratinocytes to protect it from damage, so people become darker after sun exposure, which is actually a skin self-protection mechanism. This is actually a self-protection mechanism of the skin. The reason why fair-skinned people are prone to sunburn is due to the fact that melanin particles are few and cannot effectively protect the skin.
The three most common skin tones in the world are white, yellow and black. Usually white people have fewer melanocytes and less melanin secretion, and the melanin particles are small and scattered, so the skin is white, easy to sunburn and not easy to tan; while yellow people, melanocytes are relatively more, and melanin particles are slightly larger and more, easy to tan, and yellow skin is also related to the carotene contained in the body; black people have the most melanocytes, melanin particles are very large, so the skin tone is dark. In addition, skin color is also related to the thickness of the skin and the density of blood vessels, such as the cheeks of the skin is thin so the color is rosy.
Part II 7 horrors of whitening!
1.Whitening can be done with lead and mercury
Some whitening products are very effective, and a few days after using them, it is as if the skin is transformed, and the skin immediately becomes white and bright. But then be wary of whether these products contain harmful substances such as lead and mercury. Lead and mercury can prevent the formation of melanin, and after a period of time, they accumulate in the skin, causing the skin to react to heavy metal poisoning. The skin will become pigmented and its barrier will be damaged and become weak. These harmful substances may also damage internal organs after long-term absorption by the skin, causing low fertility, etc., which is very harmful to the human body.
2, lemon mask whitening.
Whitening with lemon is also very popular today, but lemon has a strong photosensitive effect. After using lemon on the face, discoloration will form on the face after sun exposure. And the vitamin C absorbed through the face is actually minimal, and the whitening effect can be imagined. Some people also experience skin tingling after using a lemon compress.
3, take a lot of vitamin C whitening
Vitamin C has been recognized as a classic antioxidant, which can destroy free radicals, restore melanin and whiten our skin. Many people think that by taking a lot of vitamin C can achieve a good whitening effect, but I do not know that the amount of vitamin C through internal consumption to the skin is very limited, and taking too much may also cause gastrointestinal dysfunction, so you have to absorb through the skin to receive good results.
4, excessive application of fruit acid whitening
Fruit acid has a peeling effect which is well known, it can achieve the effect of peeling by peeling off the old epidermis and promoting the growth of new epidermis. But when the concentration of fruit acids is too high, more than 10%, it will produce corrosive effects on the skin. Long-term application of fruit acids, peeling the skin, but will cause the opposite effect on the skin, so the skin becomes fragile, so it is recommended to use fruit acids with caution.
5, retinoic acid anti-aging
It is a derivative of vitamin A. It can accelerate the renewal of the skin, so it is often used in medicine to treat many keratinizing diseases. Some studies have also confirmed its effect on photoaging skin. However, it is now mainly used in the treatment of diseases and has some side effects of its own, such as photosensitivity, dry skin, or teratogenic to the fetus. If used blindly, it can cause irreversible consequences.
6.Use whitening injection once and for all
Big S’s “Beauty King” is so popular that many women are scrambling to follow the methods recommended in the book. One of the debates about whitening injections is very intense. Its main ingredients are vitamin C, glutathione, and transaminic acid, which can act as an antioxidant and block melanin formation. However, glutathione and transaminic acid are themselves drugs for treating diseases, and if used in excess, they can instead cause a burden on the liver and kidneys, and even form blood clots. So don’t whitening needles a single-minded pursuit, blindly use.
7.Arsenic can whiten
In ancient times, the East and West have the same fervent pursuit of whitening, preferring to use arsenic to whiten, it is said that Cixi have used such methods to whiten, but in the present such a thing sounds horrible, but some folk recipes are also useful to whiten this. Arsenic is also known as arsenic trioxide, the treatment of leukemia has a good effect, if the dose is not well controlled will easily produce toxic reactions, damage to the organs of the whole body. So don’t try “poison” with your body.

We have to be such wise women, learn the correct knowledge of skin whitening, to do reasonable application. In ordinary life to develop good habits, to eat a balanced nutrition, sleep enough time, live a happy and dashing. Do natural whitening, healthy whitening of the smart woman!
2.Elegant school
Obsessed with whitening, think “white” women are very elegant and beautiful. “White” is a way of life, “white” is a habit of life, reflected in the details of the little by little, reflected in the details. They like their skin white, like a warm white porcelain, intoxicating, but they do not like to rush, and willing to slowly internal and external conditioning, the “white” as a lifetime thing.
Such women are very romantic, they may have a classical temperament in their bones. The woman of the ebullient school has a good grasp of the scale of whitening, they know how to slowly internal and external conditioning, not tightly dissatisfied, not sulking, can not help but be a little envious of their attitude towards whitening. But the obsession with whitening is sometimes easy to ignore the other aspects of attention, the beauty of the skin is multifaceted, “white” is important, but “white” is not all, the skin’s luster and elasticity is also an important aspect of skin beauty, so learn to the skin All-round care in order to get the most beautiful skin “white”.
3.Passionate faction
For them, “white” is the pursuit, “white” is happy, “white” is to arrive at the ultimate goal of beauty. Passionate women use skin care products, cosmetics, health products have whitening effect. They are concerned about all the information of whitening, and friends together most often discuss the topic of whitening, and always remind themselves not to forget how beautiful “white”.
Passionate women are full of enthusiasm, and they have a strong and lasting determination to whiten. If you are passionate about something, you can imagine that the results you receive will be good. Whitening is not a short process, but a long-term “business”. Passionate women do their “job” very well, they pay attention to all aspects of life, to the end of whitening. But sometimes they are too much the pursuit of white skin, and ignore the other beauty of the skin, to know our skin is the need for a variety of nutrients, in fact, in addition to fairness, the skin’s redness, elasticity is also very important.
4.Wild school
Regardless of all the consequences cost, from relatives and friends, hospital clinics, newspapers and websites all possible ways to explore the secret recipe for whitening, Chinese medicine and Western medicine, internal and external treatment. Never consider the pros and cons of various methods, as long as you can “white” regardless of everything, the money spent a lot, there may be coincidentally become a clumsy, irreparable damage to the skin.
From the dermatologist.
The wild faction of women who do things very seriously and very crazy, the fanaticism of a thing, may end up hurting themselves. They want to whiten their skin by any means necessary, maybe for their own beauty or maybe for work. Now there are many methods of whitening, the advertising is overwhelming, the effect of the propaganda is divine, there are also many unscrupulous businessmen in order to make profit and expand the effectiveness of whitening products or even with some prohibited ingredients. So the wild faction of women, for those unreliable business, no brand cosmetics, do not know the effect of the new method do not easily try, otherwise it will cause permanent damage to the skin, when it is too late to regret.
5.Hiding faction
In order to “white” strict defense, in order to “white” not to shine the sun, strictly limit their own activities outside, and become a qualified “house girl. When at home must pull the curtains, must go out, first with sunscreen, then play umbrella, hat mask sunglasses all necessary, wrapped themselves up tightly, and the sun completely isolated.
Dermatologist’s words.
The hidden faction of women believe that the sun is their own worst enemy, is the biggest killer of the skin, so they do not want to “show their faces” outside. They live a very careful life, but do not know that this inadvertently increases their psychological burden. In fact, not being exposed to the sun is only one of the factors that make us lighten our skin, but not all. What is needed for brighter skin is a beautiful mood, a healthy lifestyle, and some effective ways to protect the skin. If you spend all day at home without seeing the sun, and live a careful life, if you are really “white”, it is a sickly “white”. Skin whitening is a pursuit, not a focus of life, so don’t let it affect your life!
Part IV What medical whitening can help you do
1.Photonic skin rejuvenation technology
This method is a skin rejuvenation treatment using continuous intense pulsed photon technology at low energy, mainly using the longer wavelengths in the spectrum it emits. This specific wavelength of pulsed intense light energy crosses the epidermis and selectively acts on the pigment or blood vessels under the skin, breaking up the pigment particle clumps by light and heat energy, and then the body tissue absorbs or excretes them without damaging the surrounding normal tissue structure, so the purpose of whitening can be achieved.
The entire course of photorejuvenation usually requires 4-6 sessions, with an interval of 3-4 weeks between each treatment, and each session lasts 15-20 minutes. The treatment process can be slightly painful, and a cold gel is usually applied to the treatment area, which can alleviate the pain. Patients can resume normal activities immediately after the procedure without rest, but must avoid sun exposure after treatment. A small number of people due to individual differences or improper use of energy may appear hyperpigmentation spots, a very small number of people may appear red and blistering.
2.Beam laser cosmetic treatment
While conventional lasers emit each pulse of laser light to produce the same spot with the skin area of action, the new technology in the field of laser – beam laser is very different. Each pulse of the laser is made up of nearly 100 micro laser pulses, each with a spot area of only 75-100 UM, so that when it is applied to the skin, only a tiny area is thermally impacted, while the rest of the skin is unaffected. Similarly, the beam laser can also remove pigmentation and achieve whitening when it is applied to the skin tissue. However, compared to conventional lasers, the thermal damage during treatment is reduced, resulting in a lower incidence of side effects and making laser treatment safer. The main beam laser technologies currently in use are Erbium 2940 beam and Q1064 beam.
