Here is mainly a brief analysis of common whitening and spot-lightening ingredients on the market and market brands that use this ingredient. You can be a reference when choosing manufacturers or purchasing products. Of course, I still want to introduce my semi-finished product-spot-lightening liquid (which can be processed into mask, cream, milk, essence)For cosmetics manufacturers and cosmetics brands, it is not recommended Personal purchase. The main ingredient is licorice flavonoids. Its other name is glycyrrhizin, known as “whitening gold”, and it is usually only added to high-end skin care products, such as whitening products of brands such as Hou and Lancome. Why? Because it is expensive! ! ! MelaninThe reason why the skin turns black and produces stains is that melanin deposits on the epidermis or dermis and cannot be absorbed by cells. Especially the stains, once they settle down, they will basically always exist or even increase. There are many factors: such as hormone disorders caused by endocrine disorders, constipation, sun exposure, severe skin dehydration, pregnancy, etc. If you want a safe and effective whitening and lightening, you have to analyze what melanin is. The essence of melanin is actually protein, which is formed by different combinations of amino acids. Since it is a peptide chain, it must have a hydrolysis effect, which means that water can decompose a part of the pigment. If the water can be added to the dermal layer, the spots will naturally fade, but this takes a long time . At this time, the whitening agent is very important, either inhibit the activity of the enzyme, or cut off the melanin peptide chain, or forcefully peel off the stratum corneum. Because the formation of pigmentation is generally the participation of tyrosinase, dopa isomerase, peroxidase, and endothelin. Tyrosinase: A protease that catalyzes the production of melanin in the body. Its activity determines the amount of melanin formed. The more melanin is produced, the darker the skin. Dopachrome isomerase: another key enzyme ranked below tyrosinase, affecting the size, structure and type of melaninDHICA oxidase: affecting melanin MetabolismEndothelin: A biologically active peptide composed of 21 amino acids. It is a multifunctional physiological regulating hormone. It stimulates melanocytes to produce melanin and promotes its proliferation and differentiation. As the saying goes, one white hides a thousand ugliness, and one black destroys everything. Asian women’s pursuit of whitening and no spots is always endless, even if the beauty that prevails on mobile phones. The first thing that the camera beautifies is skin tone and stains. After whitening, the eyes, nose, and mouth are adjusted.The best word to describe a girl is “white, rich and beautiful.” White is the first place. I have to feel that the whitening market is so bigthat there are too many ingredients specializing in whitening products. The common whitening ingredients in the market include these:VC and derivatives VC is the most widely used whitening ingredient in the Phenibut Suppliers market and can prevent scurvy. Therefore, it is also called “ascorbic acid”. It is the most representative melanin production inhibitor. It inhibits the activity of tyrosinase. It also has an antioxidant effect. It can reduce the dark melanin that has been produced into light melanin, whitening The effect is very slow, and long-term persistence is needed.VC is an optically active molecule. According to the optical rotation, it can be divided into left-handed and right-handed, but because it is very unstable, it is easy to be oxidized and lose its efficacy. More VC derivatives, such as magnesium ascorbyl phosphate, etc., are written as [*****ascorbic acid] or [ascorbic acid****** in the formula of skin care products *]. The disadvantage is that it is a relatively single phosphatidase inhibitor, and the concentration is low and the effect is not enough, and the high concentration causes irritation. Therefore, the barrier is damaged and sensitive muscles are used with caution! The preservation of products containing VC and its derivatives is a very important link. They must be placed in a dark place, as they will easily lose their effect under the influence of light. Representative products include: Dr.Ci: 377VC Whitening and Brightening Essence 400RMB/18gThere is also Duke Zhenbai Day Repair Essence 1490RMB/30ml Wait for a series of brand products with VC as the whitening ingredient. NicotinamideVitamin B3, a whitening ingredient that has recently been brought to the fore. The most representative one is the OLAY small white bottle. Its whitening effect is to accelerate the shedding of the stratum corneum containing melanocytes and reduce the transport of melanin to the stratum corneum. Only when the melanin is transported to the stratum corneum will the skin appear dull and yellow-black. The combined effect of the melanin-containing stratum corneum peels off the skin naturally white. Nicotinamide can also reduce the production of fatty acids and triglycerides in sebum, that is, it can control oil, thereby reducing pores and reducing the severity of acne. There are many advantages, but there are also disadvantages. This ingredient will accelerate the shedding of the stratum corneum. The shedding of the stratum corneum of normal skin has its own rules. The new cells split from the basal layer cells and then move upwards until reaching the granular layer and finally the stratum corneum. The stratum corneum cells in the outer layer will slough off by themselves. If the sloughing speed is greater than the moving speed, the stratum corneum will thin. The best way to use it is to stop for a while to give the skin a buffer time. There is also the problem of niacinamide intolerance, niacin, which can be felt immediately after getting on the face, so you must stop immediately. Do not use products containing this ingredient anymore, she is not suitable for you. Use with caution for damaged barriers and sensitive muscles!

The antioxidant capacity is similar to that of vitamin E, and it can remove a variety of free radicals. Yes, there are so many effects, which are directly reflected in whitening, anti-oxidation, diminishing spots and acne marks, anti-bacterial and anti-inflammatory. Because it is a traditional Chinese medicine licorice extrac China Phenibut t, it has good compatibility with human skin, and its properties are relatively stable and mild. Not irritating. Known as “whitening gold” in the whitening world, it is the first choice for people who want to whiten. Most of the people who use this ingredient are Korean makeup, and they are high-end ladies’ brands.The raw materials of licorice flavonoids are also sold in China, but the finished products are few. Whoo’s post-secret patch radiant repair essence 1480 yuan/90mlChuanming AcidAlso known as tranexamic acid, it is a kind of hemostatic drug, because long-term use has been found to dilute the pigment, and thus enter cosmetics from medicine. There are tranexamic acid for food and intravenous injection. Acetic acid, the whitening needle recommended by the whitening king Da S is an intravenous injection, which contains tranexamic acid. The whitening effect is to inhibit tyrosinase activity, so the whitening effect varies from person to person. If your melanin is not caused by tyrosine Acid enzyme, then it won’t work. Nowadays, there are many people who use this ingredient to whiten and lighten spots. I won’t list them for cheap and ladies. 377Stupid ethyl meta-stupenol, now Dr. Shirano is the most popular one. The newly upgraded product is 377VC, which is combined with vitamin C for whitening, according to national regulations The addition amount of the product is up to 0.5%, but it is said that Jono is as high as 1.8%, so it cannot be produced in China. I am not sure about this. Look, a main ingredient is actually only added in a small amount in skin care products, and these functional ingredients are not added as much as possible. The higher the concentration, the better. It is easy to cause skin allergies. The reaction is even bad face. There are also hydroquinone, glutathione and some plant extracts. Many whitening products are not single-component whitening, most of which are compounded. The compounding of two or more whitening ingredients requires higher stability and compatibility of the entire formula. And most of them are related to acid. I would write that sensitive muscles should be used with caution, because people with thin skin can’t stand the toss. Acid can exfoliate the stratum corneum. After the outer layer of melanin-containing keratinocytes fall off, the skin will become smooth and white, but Since the growth rate of the skin itself cannot keep up with the rate of shedding, it will cause the skin to become thinner and more sensitive to ultraviolet rays, but it is more likely to darken. It is obviously used for whitening, and finally darker and more spots. The PH value of oriental skin is generally between 4.5-6, and the PH value of skin care products is preferably between 5-5.5. Skin care products lower or higher than this value will be used for a long time. Destroy the acid-base balance of the skin, leading to dryness, thinning, sensitivity, red blood streaks, and a lot of oil. The change from normal skin to sensitive skin is mostly related to improper use of skin care products. The road to whitening is long and long, and there are many pitfalls. For the sake of whitening, abandoning the original healthy skin is not worth the loss, so please choose whitening products carefully.
