Who doesn't want to cover up three ugliness for nothing?
It is because everyone wants to whiten, so many businesses are eyeing this business opportunity and madly promoting their whitening products. Searching for a book is full of titles such as "whitening in two days", "whitening twice a week" and "whitening with LED lights". Even the facial cleanser turned white. A large number of girls wave after wave, and the merchants earn a lot of money, but they haven't turned white after spending the money, and they fell and got up on the way to whitening.
Whitening has never happened overnight, and it needs long-term persistence. Everyone's whitening has an upper limit. This may hit you a little hard, but don't believe that it is unrealistic to instantly whiten warm yellow skin into cold white skin. The only way may be-beauty camera! All right, cut the crap. Today, I will share with you how to whiten scientifically and effectively from my years of whitening experience.
I have seen many whitening strategies before, and I have used many whitening essences, saying that various whitening ingredients have been added to them, and nothing has changed after half a year's use. There is also a whitening mask that I insist on using every night, and nothing has changed. I have tried many remedies, for example, washing my face with white vinegar can whiten my face (my face is almost allergic to it), drinking lemonade can whiten my face (I see that the acid in lemonade is not white) and drinking milk can whiten my face (after drinking for several months, I have become fat and black). So don't believe the ineffective whitening products boasted in the market, and don't be superstitious about folk remedies. Scientific whitening is the right way.
If you want to turn white, you must first understand why we turn black, because melanin is produced by melanocytes. When ultraviolet rays harm our skin, melanocytes produce melanin to protect our skin from ultraviolet rays. Therefore, the principle of whitening is divided into two steps: preventing melanin production and reducing the generated melanin into colorless melanin precursors (it doesn't matter if you don't understand, look down at the dry goods).
1, physical sun protection (umbrella+hat+sleeve)
This is my most commonly used method, because I can't get up in the morning, so I often don't have time to apply sunscreen, and I spend most of my working time indoors. Therefore, I usually take my hat and umbrella when I go out. The hat can not only protect the sun, but also cover the hair that was blown up in the wrong sleeping position last night. It can also cover the oil head that has not been washed for two days. It is omnipotent. An umbrella protects against the sun, no sun and rain, and no leucorrhea. Cufflinks are usually used when wearing short sleeves in summer, and then wearing masks every day because of the epidemic. Basically, this sunscreen is enough.
2. Chemical sunscreen (sunscreen)
Sunscreen is generally selected according to personal preference. Look at those sunscreen evaluations, from an objective point of view. It is best to buy sunscreen products separately for the body and face, and the sensitivity is different. Universal products may not be suitable for everyone. If you don't sweat much indoors, you don't need to put sunscreen on your face. If you are outdoors, you need to apply sunscreen, usually once every two hours (I still think physical sunscreen is the best, or it may be because I am lazy). Sun protection mainly depends on two indicators: SPF value (sun protection index): mainly for UVB protection, sun protection and sun protection. PA value: mainly for UVA (long wave ultraviolet) protection, sunscreen black. Under normal circumstances, SPF30 and PA++ sunscreen can be used. If you are outdoors for a long time, sweating and touching water, such as swimming in the seaside, plateau or open air, choose SPF50+ and pa++ for waterproof and sun protection.
As mentioned earlier, the main cause of skin blackening is melanin, and the root of melanin production lies in tyrosinase, so inhibiting the biosynthesis of tyrosinase is the key to whitening. Vitamin C can inhibit the activity of tyrosinase, reduce the production of melanin, has certain antioxidant effect, and can reduce the formed melanin to colorless melanin precursor, thus improving the dullness of skin and achieving the effect of whitening.
But why do many people eat vitamin C and find it doesn't turn white?
1, maybe the meal time is too short.
It is unrealistic to want to turn white in a short time. Generally, the skin condition can be improved in one month, but it takes more than three months to see the change of skin color with the naked eye. It took me four months to see with the naked eye that I turned white. Don't be impatient.
2. Because I didn't choose the right vitamin C.
When I first started eating, I also went to the drugstore and bought a large bottle of vitamin C effervescent tablets for a few dollars. I found it useless after eating it for half a year. Later, I read a popular science article saying that the daily intake should reach a certain level. I looked at the effervescent tablets I bought. Each tablet weighing 4g only contained 90mg of vitamin C, and most of the others were added with sugar and additional additives. The vitamin C content of an orange is about 50 mg. No wonder it's useless to eat for so long.
After stepping on a lot of pits, I found that pharmacies sell many additives, which are not single in composition and low in content. The ones recommended by the clerk are also expensive, saying that they are imported, but if you look at the ingredients list, there are still many additives with low content. Then I found a circle of evaluation on the Internet, and selected an imported orange bag professional-grade vitamin C product among many brands. It is found to be a single tonic with high purity and large dosage. Effervescent tablets are natural ingredients without sodium, sugar and other auxiliary materials. Long-term use will not cause a burden to the body, and the content is as high as 500 mg, which can meet the daily health needs.
After eating for half a year, I found that my skin turned white, and my skin was in good condition and healthy. Professional products are really different. So whitening should be scientific. Don't use whitening products that you haven't heard of, and don't try your face with folk remedies. Whitening by facial cleanser and mask is basically unreliable. It is still honest to combine internal and external whitening and insist on taking vitamins and sunscreen.
