Skin melanocytes produce melanin, which is transported and carried by keratinocytes, evenly distributed on the skin surface, and then falls off with dead skin cells. This process of melanin metabolism is the basis of skin color. Different people's skin melanin content and distribution are different, forming different skin colors; The disorder of melanin metabolism leads to pigmentation and pigmentation of skin. Melanin metabolism is also affected by skin damage and irritation.
The texture and richness of skin determine the permeability and luster of skin.
Healthy skin is firm, elastic and layered. This kind of skin can reflect light in all directions, and the skin will show the pink, transparent and shiny characteristics that women like best. When the skin begins to age, the layer, texture and elasticity of the skin will change, resulting in changes in skin luster and permeability, and the skin will become dull.
Physical health affects the overall skin color.
The change of physical health and the increase of age will affect the levels of various hormones in the body as a whole, and also affect the absorption and content of vitamins and minerals in the body. This result will cause various skin color changes. People are in a good mood when they are happy, and women will be described as "peach blossoms on their faces" when they are happy; When people are old or in poor health, they will become pale.
1. Whitening ingredients have different effects.

2. Whitening double-edged sword and weights and measures
In real life, people will find many kinds of whitening products on the market, and in nursing, some products emphasize rapid whitening, some products emphasize intensive whitening, and some products emphasize daily whitening care. So, with so many whitening products and concepts, which whitening products and whitening methods are suitable for your skin?
1. Intensive whitening and daily whitening
Rapid and intensive whitening refers to the use of so-called high-concentration whitening products to help skin whiten in a short time. This is in line with the psychology of people who want to get rid of skin spots and dullness as soon as possible. Therefore, the idea of rapid and intensive whitening will always attract the attention of women who are willing to make their skin white and flawless.
Daily whitening is a method and concept to improve skin melanin metabolism and the overall health of skin cells, and to persist in using whitening products for a long time, so as to achieve whitening effect. Healthy skin color is flawless and natural, so people who firmly believe in daily skin care and whitening not only want their skin to turn white, but also want to keep it healthy fundamentally.
Daily whitening is like a trickle to the skin, which moistens things silently and can maintain and achieve the healthy state of the skin. Rapid and intensive whitening may be like a heavy rain or even a flash flood for the skin. In this way, the skin may bear a "rich gift" in a short time, but it may not be fully absorbed by the skin in a short time. If too much emphasis is placed on fast and dense, it may also cause extra pressure on the skin.
2. Concentration and aging of whitening products
Fast and intensive whitening products usually emphasize that the whitening active ingredients contained in them are higher than ordinary whitening products, or use products intensively and frequently, so as to achieve whitening effect in a short time. It is no exaggeration to say that the content of active ingredients can really enhance the effect, but it still takes time to take effect, otherwise it does not conform to the actual skin physiological metabolism law.
After rapid and intensive whitening, it doesn't mean that you can't continue to use such high-concentration products, nor does it mean that you have to use such rapid and intensive whitening products several times a year to achieve results, let alone use such products more than several times a year.

Four methods of whitening
Whitening method 1: Drink lemonade.
Drinking more water is good for skin 100%. Girls get up in the morning and drink a cup of warm water to promote gastrointestinal peristalsis. You can also soak fresh lemon slices in warm water, which contains a lot of vitamin C, which can help the skin to resist oxidation and whiten easily.
Whitening method 2: supplement vitamin C.
For girls' skin, vitamin C can achieve a good whitening effect. Eating more foods containing vitamin C is a good way to naturally whiten skin. For example, cucumbers, tomatoes, strawberries and oranges are rich in whitening ingredients, which can well inhibit the formation of melanin.
Whitening method 3: Q 1 crystal extraction mask
This is a hydrating mask that was discovered by accident a long time ago. The skin feels smooth and moisturizes for a long time after application. Personally, I think the biggest advantage of this mask is its super hydrating ability, which makes the follow-up essence and cream better absorbed. When it was used at that time, not many people knew it. I was going to keep it a secret. Now the internet is going to ruin the street, so I want to share with you this secret whitening trick.
Whitening method 4: vinegar+salt
Vinegar and salt are common condiments in our life. In fact, they have a good effect on beauty and skin care, and the whitening effect is very obvious. First, dissolve vinegar and salt in water in proportion, about water: white vinegar: salt = 9: 3: 1, then soak it in a towel and gently rub it on your face once in the morning and evening. Slowly, you will find that your skin is no longer dull and looks much whiter.
Three kinds of whitening food
Whitening food 1: VC whitening ingredients
Representative food: Lemon, strawberry, blueberry, cranberry, grape and other foods rich in vitamin C can be made into juice according to your own preferences. A cup every morning can not only eliminate toxic substances in the body, but also have a natural whitening effect, which helps to eliminate facial freckles. Some people like to mash all kinds of fruits directly and apply them to their faces to make masks. In fact, this is too irritating to the skin, but it will be counterproductive. It is better to eat them and the effect will be better.
Whitening Food 2: Detoxifying Whitening Ingredients
Representative food: green tea, cucumber, green papaya. Drink a small bag of green tea every day, or boil green tea peas, add honey and medlar after boiling. Cucumber and papaya can be eaten raw, steamed or fried directly, but they should be covered when fried to avoid contact with air for too long. In addition to soaking in water, green tea can also be made into tea bags and placed in the bathtub to detoxify while taking a bath.
Whitening food 3: moisturizing and whitening ingredients
Represents food: aloe, rose. You can plant an aloe by yourself, take a small piece at a time, peel it, cut the pulp into pieces, cook it in a pot for one minute, then pour out the water and the pulp together, and add some honey to drink. Roses can also soak in water at ordinary times.
