Whitening is the topic that all little fairies and little fresh meat are most concerned about in summer, after all, everyone wants to show their white little arms and long legs.
But on the road of whitening, presumably many friends are -
Taste the Internet in a thousand ways
It's up to you to go black in the end
Today, HealthJun will give you a good talk about what you need to know about whitening.
To be a piggy girl or treasure boy for nothing
So first understand why you turn black?
The vast majority of our skin color comes from the melanin pigment of skin cells.
When the skin is exposed to the sun, melanin comes out to protect our skin, absorbing 99.9% of ultraviolet rays, but at the cost of our skin tone quickly becoming dull and dull.
In addition to ultraviolet rays, the factors that darken the skin are as follows:
Stay up late
malnutrition
Long-term friction
Endocrine disorders
Cosmetics with excessive heavy metals
Therefore, as long as - reduce melanin , that is, inhibit the formation of melanin, the skin will turn white
And the various whitening methods circulating on the Internet, in fact, most of them are unreliable, and some even affect physical health.

These methods do not whiten ///
-1- Can tomato and lemonade whiten?
- and not -
Regarding the basis for saying that tomatoes, lemons, etc. can be whitened, most of them can "supplement lycopene, vitamin C".
First of all, lycopene can hardly be obtained by "eating", and at the same time, searching on the Internet, you can also find many cases of stomach ulcers caused by eating tomatoes.
In addition, the vitamin C content in lemons and tomatoes is not much in fruits and vegetables.
Lemon is about 22mg/100g
Tomatoes are about 19mg/100g
And some of the kings of vitamin C, such as:
Jujube 243mg/100g
Green pepper 62mg/100g
Compared with these, it seems that lemon and tomato are younger brothers.
At the same time, the body's absorption of vitamin C is saturated, that is, even if you want to eat more tomatoes and drink more glasses of lemonade to supplement vitamin C, it is not feasible.
-2- White vinegar and pearl powder can whiten?
- and not -
The method of "white vinegar face whitening" is low-cost and easy to operate, and many people have stepped on this pit.
The main component of white vinegar is acetic acid, which is highly irritating and will burn the stratum corneum on the surface of the skin, causing great damage to the skin.
"Pearl powder on the face" whitening is an illusion - the insoluble powder particles left when rubbing pearl powder are stuck in the pores and look "white".
-3- Exfoliate every day to be white?
- and not -
Some little fairies have heard that "keratin" will make the skin dull, and they want to give the skin a keratin cleaning every day.
You know, the renewal of the stratum corneum of the skin has a fixed cycle. Wrong, excessive exfoliation will only make the skin sensitive, fragile, let alone whiten.
Whitening just do this ///
If you want to turn white, it is actually not difficult, and it is enough to do a good job of these two points summarized by Health Jun:
01 Stay up less! Don't stay up late!
If you often stay up late and don't sleep enough, free radicals continue to accumulate in the body, and your skin will naturally look haggard and dull.
While we sleep, our bodies and skin are at a time to rest and repair themselves.
Ensuring 7-9 hours of deep sleep every day not only allows the skin to remove toxins well, but also ensures the full secretion of melatonin and resists free radicals, which is the key to natural whiteness!
And for sleeping
There may be people who go to bed early and get up early
Some go to bed late and get up late
What exactly does it take to stay up late?
Theoretically, people who go to bed late are not necessarily in worse spirits than people who go to bed early, because everyone's sleep habits are different, and the focus of measuring sleep quality is "developing a regular + sleeping enough to sleep well".
So
Go to bed late and get up early
Sleep not enough for 7-9 hours
Didn't sleep well
Irregularity
These are the "staying up late" of the right solution.
It can be seen that compared to people who sleep at 10 o'clock, people who sleep at 2 o'clock in the morning just adjust the sleep time later, as long as they can ensure sleep time and quality, and have good rules, it is not considered to stay up late.
02
The second key to whitening, whether outdoors or indoors, must be done well - sun protection!
Not only in summer, but also in the sun, even if it is rainy and cloudy. as long as
UV index ≥ 3
Your skin is at risk of sunburn.
Some friends will ask
Do I need sun protection when I go out at night?
Not required. Ultraviolet rays at night are very weak enough to tan the skin.
However, in some places such as bars and KTV and other public places, all kinds of lights inside contain ultraviolet rays, so children's shoes that generally do not like to go out at night are generally white.
··· ··· ··· ···
There are two commonly used sun protection methods: "hard sunscreen" and "soft sunscreen".
"Hard sun protection" refers to the method of physical blocking to block ultraviolet rays, how much can be blocked.
It is recommended that people with sensitive skin and acne skin use more physical sun protection to reduce the irritation of sunscreen to the skin.
"Soft sunscreen" refers to applying sunscreen to block or absorb ultraviolet rays.
For those who spend a long time indoors, it is recommended to use SPF15 or PA+ sunscreen and apply it every 4-5 hours.
Outdoor athletes recommend using SPF25-30 or PA++ sunscreen every 3-4 hours.
For outdoor swimming, it is best to use a waterproof sunscreen with SPF30 or PA+++ or above, and apply it every 1-2 hours.
Generally speaking, the amount of about one $1 coin at a time is fine.
On the road to whitening, there are not so many bells and whistles, I wish my friends can be white to shine with Health~!!
