1, vitamin c whitening misunderstanding
Can vitamin C really whiten the skin?
Everyone knows that it can prevent scurvy and improve immunity. There are also many VC whitening recommended by beauty experts. It is said that you may not know much about it. In fact, vitamin C has long been widely used in whitening skin care products, and is known as the "classic natural whitening element". Oral vitamin C, starting from melanocytes in the basal layer of skin, can inhibit tyrosinase activity, block melanin production and improve skin whiteness from the inside out.
How much dose is VC safe to take every day?
From the perspective of long-term skin care, it is recommended to take about 100 mg every day, which is safe and effective and will not cause so-called side effects. In addition, I suggest you choose natural vitamin C products. Here is a lesson for everyone. Only a truly natural VC can be called "natural vitamin C". There are many VC products on the market, several or a dozen, but generally these products are synthetic VC, so you should pay attention when choosing!
Is natural vitamin C really better than synthetic vitamin C?
Although there is no difference in chemical composition between the two, natural VC is generally made of rare fruits, such as west Indian cherry and kiwi fruit, and contains trace elements such as vitamin P, which can prevent VC from being damaged by oxidation and help it be better absorbed by human body. But the cost of synthesizing VC is low, and the general dosage is relatively high. If you take VC 1000 mg every day, it is easy to cause oxalic acid or uric acid stones. For example, some OTC medicinal VC belongs to the category of drugs, which are generally used to treat diseases as adjuvant treatment, and long-term use is not recommended.
How many times a day is it better to eat VC?
It is best to eat it twice a day. Because VC is a water-soluble vitamin, generally speaking, it will be discharged with body fluids in 3-4 hours. Repeated supplementation at intervals of 3-4 hours can ensure the content of VC in the body and the absorption effect will be better.
When should VC be eaten?
It is best to eat after breakfast or lunch! Everyone knows that fruit is "gold in the morning and silver at noon", and so is VC, especially some VC products extracted from natural fruits, which will be eaten at breakfast or lunch.
Want to whiten by oral VC, how long does it take?
Whitening is like a war, and the game with melanin needs a steady stream of bullets, otherwise the melanin that has just been repelled will quickly cheer up and have stronger combat effectiveness. Oral administration for at least 3-6 months, the effect will be more obvious, because it is absorbed by the human body through the stomach, and it takes a process to help cells update step by step and improve skin color from the root. Any way to exaggerate the publicity effect is not conducive to health.
Can eating more fresh fruits and vegetables rich in VC whiten your skin?
It depends on a person's physique. Cherry, kiwi fruit, cucumber, strawberry, tomato and orange are rich in vitamin C. However, although vitamin C is widely found in vegetables and fruits, it is the most unstable water-soluble antioxidant with short shelf life and easy oxidation. For example, after picking green leafy vegetables for 2 hours, the loss of VC is 5- 18%, and after 10 hour, it is 38-66%. Moreover, the vegetables eaten by Chinese residents are mainly cooked food, and VC is seriously lost in the cooking process, and the utilization rate is less than 50%. Therefore, if the intake from vegetables and fruits does not reach the corresponding functional dose, it often fails to play an ideal cosmetic role. If you want to whiten, it is recommended to increase the intake of VC.
Is the homemade VC whitening mask rumored on the Internet really effective?
It is widely rumored on the Internet that the method of mashing vitamin C, dissolving it in mineral water, and then soaking it with a compressed mask is effective in a short time. However, due to the strong antioxidant capacity of VC, if it is not mastered well, it is easy to produce tingling. Don't make such an attempt for allergic mm.
2, autumn skin care and moisturizing methods
Preparation: Gently exfoliate.
After summer, the skin becomes rough, the stratum corneum gradually thickens, and becomes very unhealthy, which easily leads to a series of skin problems in autumn and winter, and also affects the absorption of moisturizing and hydrating products and the water retention of the skin. Therefore, the most critical step before autumn moisturizing work is gentle exfoliation.
You can choose gauze towels for your baby. After wetting your face, soak the towel in the cleanser and rub out the foam. Then gently apply the cleanser in a circular motion on the face, especially on the forehead, T-zone, chin and other parts that are easy to accumulate waste keratin. It's not long, about 30 seconds. Then rinse with clean water. If it's too much trouble, you can use exfoliating products directly.
Daily moisturizing tips: emulsion wet compress
The alternation of seasons always catches the sensitive MM off guard. But in fact, MM can be wet-packed with the emulsion at hand. Before putting on makeup or before going to bed for maintenance, use a cotton pad to absorb the lotion, and then apply it for about five minutes before the daily maintenance step. The skin has high water content and naturally moisturizes and replenishes water. However, it should be noted that the emulsion should not contain alcohol.
Daily moisturizing instructions: use moisturizing milk.
Climate change is unstable, and the average 28-day renewal cycle of stratum corneum will be disrupted. When you find that the skin's locking power is getting worse and drier, you should pay attention to improving it. Use more moisturizing lotion than usual, pour it on a cotton pad and gently massage the skin in circles. The water retention of skin will be improved immediately, and the appetite of skin will be greatly increased. Subsequent maintenance will be better absorbed.
Daily moisturizing tip: don't forget to protect yourself from the sun.
It's getting cold in autumn, but MM, don't take ultraviolet light lightly. The amount of ultraviolet rays in autumn is actually the same as that in summer. Don't let the whitening plan go to waste. Sunscreen products should continue to be used. Don't choose Lycra white sunscreen that needs to be shaken well, choose emulsion sunscreen products with less water. So you don't have to worry about the damage of dry weather to the stratum corneum.
Daily moisturizing instructions: special moisturizing care
You can choose to add meals to your skin 2-3 times a week. After washing your face, directly rub the moisturizing cream on the palm of your hand and apply it to your face, then wring out the cotton pad soaked in pure water until it doesn't drip completely, then soak the moisturizing emulsion, apply it to your face, cover it with a layer of plastic wrap, take it off in about 10 minutes, and pat the unabsorbed product until it is completely absorbed.
