Rarely did not have to work overtime on the weekend, Xiao Xiao and his girlfriend played outside for a day, and it was too late at night, so they lived together in Xiao Xiao's house.
At this moment, Xiao Xiao was taking a bath and washing happily, and suddenly felt a chill behind her, as if she had a pair of eyes staring at herself. Turning her head, she didn't expect to meet the eyes outside the door, and she cried out with an "ah~".
The girlfriend's heartless smile came in through the crack of the door, laughing and explaining, when I just changed clothes and looked in the mirror, I found that I had a black ass, and I was curious to know if Xiao Xiao had it, so there was an embarrassing scene just now...
At the end, the girlfriend also added a sentence, "Although I don't have a strong color, I am relieved to see that you also have a black ass."
I rub!

As a delicate little fairy, why is there such an embarrassing thing as a black ass? Not only that, but my skin is white and beautiful, why do some parts of my body turn black inexplicably?
Our skin color number is mainly related to melanin [1]. The number of melanocytes varies from part of the body (e.g., face, neck, upper limbs and lower limbs) [2], and is also affected by acquired factors such as ultraviolet radiation.
But the ass is wrapped in clothes all day, how did the two lumps of black come from? If the fart can talk, maybe it can't help but accuse: the pear is too big!
Complaint I:
Whether human beings are lying or sitting, basically rely on farts to support, this part of the skin for a long time in the sciatic nodules and chairs between the survival, skin blood circulation becomes worse, peach-like farts slowly become "black farts", really too difficult!
Complaint 2:
Rub repeatedly! Especially those who wear tight clothes, it is inevitable to rub with the outside world. In the long run, the cuticle of the fart is getting thicker and thicker, and the black fart will follow!
Complaint III:
Too half a month! Obesity can lead to uneven distribution of the skin cellulite underneath, increased skin folds, and thicker cuticles, so black farts are coming again!
Want to make the black fart disappear, the little fairies don't sit all the time, walk around more, lose weight. You can also prepare a comfortable cushion for yourself, use some exfoliating skin care products, practice hip movements, etc., you can try it.
If you think these methods are too troublesome, there is a way to "once and for all", that is, to break the mirror, the eyes are not pure, and the invisible is not!
Life is always strange, socks are always lost, knees are always inexplicably blue and purple, I can't remember how it hit, but it really appeared, and sometimes even suspected that it was beaten in a dream...
There are bruises on the knees, wearing skirts is not good, even if it is not good, walking on the road, always let some boys have misunderstandings. I just want to say that if you want to be crooked, you have to face the wall!
Girls always have bruises on their knees, and the truth is actually very simple!
Compared with boys with thick skin, girls have weaker subcutaneous capillaries. A little external force may cause it to be injured and ruptured and bleeding, platelets and coagulation factors are too late to repair, and the blood is dispersed in the subcutaneous tissue of the body, so from the appearance, there is bruising.
In addition, estrogen has a dilating effect on blood vessels, which is not conducive to vascular repair [3]. Therefore, girls are really too difficult, and girls with bruises on their knees are really angels with folded wings in the previous life!

Although the bruises are not good-looking, they do not have much impact on physical health, and if they are not treated, they will generally dissipate in 1 to 2 weeks. If you want to make the bruise disappear quickly, you can apply cold compresses for 2 days to relieve pain, and after 2 days switch to hot compresses to promote blood circulation.
It should be noted that some diseases can also cause platelet abnormalities and bruises. For example, leukemia, purpura and so on. If bruises often appear on your body and can not be dissipated, it is best to find a professional doctor to check it.
The color of the nipples and areolas is determined by genetic factors.
In general, the body is not fully developed before puberty, the level of sex hormones is low, and the areola is pink. After puberty, as the level of sex hormones increases, pigmentation occurs, and the color of the nipple areola deepens to brown.
During pregnancy and lactation, hormone levels change, the nipples and areola become larger in diameter, and the color deepens to a dark brown color.
Therefore, the color changes of the nipples and areolas, which are related to normal changes in sex hormone levels, are characteristics of healthy women. It has little to do with the abundance of sexual life, and the same is true for the "private parts" to turn black.
There are also people who suspect that long-term friction wearing underwear will lead to deepening of the color of the areola, in fact, the areola part of the skin is low and not easy to accumulate, so even if it is often rubbed, the impact on the color change of the areola is not very large.
As for friends who want to change the color through "coloring" and "bleaching" products, don't waste your efforts, save the money to buy delicious and not fragrant?
