In life, I often hear girls say this to boys:
“Hello oil, you are the machine of the oil press”
“How can you be so shameless, your skin is thicker than the city wall”
“Stinky man, can you stay away from me”
…
Not found, these quotes girls always seem to blurt out naturally, and have even become an established concept. “greasy, cheeky, smelly man“, these tags seem to be exclusively for men.
Actually, this is all evidence-based, not groundless. This starts with the “skin”, the largest organ in the human body, because these differences do exist in males compared to females.
Men’s stratum corneum is thicker than women’s
It is said that when chasing girls, boys need to be thick-skinned, but they are really “cheek-skinned“.
Studies show that men have thicker stratum corneum and dermis than women at all ages.
Because men’s dermis contains more water, matrix, and elastic fibers than women’s, all of which help increase skin thickness.
Interestingly, men’s skin thickness starts at age 20 and decreases with age; After the age of 50, it begins to decline rapidly, and the signs of aging are visible to the naked eye.
This is why some girls spend a lot of money to buy skin care products to smash their faces, but the results are not as good as boyfriends who don’t take care of their skin, because they are
Talent, Gifted, Unique, Gifted
So being “thick-skinned” is a good thing? There is a word “skin rough and meat thick” that also makes sense.
Men with thicker skin are more likely to have a relatively strong skin barrier that can withstand the sun, sun and sensitive stimuli. But at the same time, the texture is relatively rough, and it doesn’t feel so smooth and delicate to the touch (if you don’t believe it, you can randomly grab the man next to you and feel it, or touch it yourself).
Men are more oily than women
I found no, there will always be a pool of yellow stains on the collars and pillows of boys, as if they were poured over with peanut oil. This is because boys really like to be oilier than girls.
Our scalp, forehead, cheeks, chin have 400-900 sebaceous glands per square centimeter, sebaceous glands secrete sebum, sebum It is composed of glycerol and free fatty acids (57%), wax esters (26%), squalene (12%), cholesterol esters (3%) and cholesterol (1.5%).
The pool of yellow on the boy’s pillow is not something indescribable, it is purely “colored” caused by sebum.
The sebum composition of men and women is the same, but men are more prone to acne and other skin because of their higher androgen levels and sebum production, as well as larger pores. question.
Boys are more prone to breakouts during oily puberty.
However, with age, sebaceous gland secretion in both sexes decreases, and the difference in oil production increases.getting smaller.
Men are more likely to be bald than women
Hair loss is everyone’s nightmare, and the most often ridiculed is the bald programmer. Is this a stereotype of boys or is it true?
In fact, both men and women suffer from hair loss, but men suffer more than women because men have higher androgen levels.
The most common type of hair loss is androgenetic alopecia (baldness), which accounts for more than 90% of male hair loss. Men do not pass on women.
In China, the prevalence rate was 21.3% in men and 6.0% in women.
In males, the hair on both sides of the forehead is slender and sparse, gradually extending to the top of the head, and the hairline on the forehead recedes back, The forehead becomes high and M-shaped, and finally forms “Mediterranean”.
Women’s disease is relatively mild, mainly characterized by sparse hair on the top of the head, significantly wider hair seams, and rarely receding of the forehead hairline.
Men are smellier than women
Girls talk about “stinky men”. You think it’s a petty fight and the sour smell of love is recklessly diffused, but in fact, it may be really harassed by the smell.
The production of body odor is a hodgepodge of sebum, sweat, and bacteria. We have already said that the sebaceous glands of men are a more productive oil well. Under the influence of androgens, the perspiration rate will be 30-40% higher than that of girls.
Sweat is originally colorless and odorless, but when sweat and sebum are mixed together, there is a milky white mass in areas that sweat a lot, and bacteria break down Under the action, the mixture of bacteria + sweat + sebum will produce a delicious taste like fermented sauerkraut.
Boys, as “big owners” of sebum and sweat, naturally stink more than girls.
In addition to physical differences, most women will be more delicate in their daily lives. After all kinds of skin care products, perfumes, shower gels, etc. are marinated, everyone can be a “fragrant concubine” .
Although there is the skin structure of men and women is different, you can still get rid of the “greasy” as long as you pay attention to personal hygiene and change your clothes and bedding frequently “, “smelly man” and other titles, as long as you are not lazy
