Liu Liping said dejectedly: "Then it's useless to use cosmetics at all?"

Xu Yi said with a smile: "I didn't say that, I just said that cosmetics and skin care products can't achieve the fundamental purpose of improving the skin at all, at least these things can still do the basic purpose of covering up skin blemishes or moisturizing, and it's like anti-ultraviolet cosmetics If used correctly, this can also reduce the impact of ultraviolet rays on the skin." ”

"What's more, this makeup can also reduce the stress of the girls and make them more confident or something. However, these things are always foreign things, and contain various chemicals and even harmful substances, it is difficult to say that this thing is not harmful to the skin, or it has to be done in moderation, it is better to use less, this cosmetics will undoubtedly change the pH of the normal skin and the sebaceous film on the surface of the skin and even the integrity and thickness of the stratum corneum cells, if you use it for a long time, it is difficult to say that it will not cause harm to the skin, if you want to encounter the kind of substances such as adding hormones to it, I am afraid that it is not only harmful to the skin, which will inevitably affect the health of the whole body。 ”

"It's impossible for ordinary people to look like a star all day long and need to appear a lot, although it doesn't have to be plain, but heavy makeup is always unnecessary, it's good to use a little moisturizer or something when necessary, and if you have oily skin, use a slightly alkaline soap to properly wash the oil on the lower face, as for other things, it's not necessary at all. ”

"The properties of the skin are affected by a variety of factors, and you don't have to think that you can have any improvement and beauty effects on the skin by eating one or two things, after all, the human body needs dozens of trace elements, and there are thousands of compounds in the body. Even if your skin can absorb these things completely, it won't be replenished by your small bottle of makeup. What's more, this skin can't absorb these things at all. ”

"Everyone's skin is a reflection of their nutritional balance, and it's impossible to see it at a glance. It is impossible to distinguish what additional nutrients you need to supplement, but what the skin lacks, which is also the lack of nutrients in your whole body, properly adjust the food structure, which is far more economical than applying cosmetics, and the potential benefits are more, after all, people do not live by just a stinky skin. ”

"But that's not all, it's like you put a big table of delicacies on the table. The old man just ate some vegetables and put down his chopsticks, after all, their gastrointestinal tract has degenerated to the point that they can't bear the big fish and meat. The same goes for skin cells, even if your body has enough nutrients to transport to the skin through the capillaries, you still have to consider the level of division and proliferation of skin cells, as well as the anabolic capacity. Even if you eat more nutrients, you can't grow an inch and a half taller when the epiphysis is closed, and it can't change the change of cell division and synthesis ability due to aging, which is the root cause of skin laxity and wrinkles. ”

Liu Liping asked: "That's what it looks like." Can't you change it?"

Xu Yi smiled and said: "From the theoretical perspective of medical cosmetology, there is indeed a way to improve this problem, that is, to activate the telomeres of cell chromosomes. This allows the cell to maintain its vigorous ability to divide. ”

Liu Liping pursed her lips and said, "It sounds so profound." ”

Xu Yi nodded: "This research is still in the real room stage, and it has not yet progressed to the stage of clinical application, after all, this splitting ability has been enhanced." It is also characteristic of cancer cells, and this method was tried in mice. It was found that the mouse's skin cells maintained a vigorous ability to divide, and it was found that this did make it possible to have a youthful appearance. However, this also has a fairly high risk of carcinogenicity, so it is impossible to enter the clinical application stage for a while. ”

"In addition to these most important factors, there are other factors, such as the effect of sex hormone levels on the skin. ”

"Increased levels of androgens tend to lead to sebaceous glands, sweat glands and hair hyperplasia, which accelerates fat burning, while estrogen has an antagonistic effect on it, but you can't use drugs and other ways to change the hormone levels in the body for the sake of good skin, so I'm afraid it will outweigh the losses." Even the effect of hormone levels on fat also affects the surface of the skin, speaking of which, you see that the skin of a few fat people will be very poor, and which person who is as thin as the fourth child will have good skin?"

"Coupled with the living environment, as well as the influence of chemicals, mood and other influences, this together creates a person's skin surface, it can be said that the beauty and care of this skin is also a very complicated science, far from the little things you can grasp by relying on the Internet and hearsay. ”

"It can be said that even those sales ladies who sell all kinds of cosmetics like you can't really have advanced theoretical knowledge, they just sell you all kinds of things for sales performance and sales commissions. Strictly speaking, the most reliable way to use cosmetics is not how much money you spend on what kind of things you buy, but what you buy that is more suitable for your skin, which has little to do with the price. A person who has worn makeup has good skin, and it is likely that her makeup looks more suitable for her. ”

"If a girl without makeup still has good skin, then you have to consider whether she is younger and more comfortable without heart and lungs. There is no pressure and regular work and rest, plus the diet is relatively balanced all day long, and there is no serious disease, which naturally ensures that her skin condition will be very good. ”

The fat man interjected again: "Actually, in addition to these, I also know a secret to skin care, try it all out, do you want to know?"

Liu Liping said with a straight face: "You'd better not say it, the third child is talking about knowledge, where is it like you running a train with your mouth full, what you say is not serious." ”

The fat man laughed: "Look, Xiao Liu is smart, I don't have to say it to her to understand!"

"Expression and gravity are a woman's greatest enemies. The best way to be afraid of wrinkles is to put on a dead face all day long. The tomb of the living dead in Jin Daxia's pen looks like a holy place for beauty and beauty, there is no daylight, and there is no interpersonal communication, so naturally there are no seven emotions and six desires, if you want to beautify, you will lead the fourth child there, and raise a bird. ”

Liu Liping was not annoyed, and sneered at Yu Hangsheng: "Dead fatty, you only have a dead face, I recruited you to provoke you, just be angry with me if you have nothing to do!

"Xiao Liu, don't be so ruthless, you really dare to ...... like this" The fat man jumped up from the sofa and said viciously.

Liu Liping sat there and squinted at Yu Hangsheng. "Why, you still want to kill people, come on, hurry up. ”

I saw the fat man put his hands together, then bowed deeply, and said, "Sister, I was wrong, please spare me!"

"Hmph, I'll spare you this time, see if you dare to mess with me next time!" Liu Liping smiled triumphantly, then turned her head and asked Xu Yi: "Third child, you thin skin and tender meat, tell me about your maintenance experience, your skin is whiter and more tender than more than half of a woman." ”

Xu Yi couldn't cry or laugh, where is this, if it weren't for the space, although he wasn't black, it was just the unhealthy white with less sun. "I'm a big man, and I don't rely on this face to eat, what do I maintain, you have forgotten that I am about to become a full-time night shift in the Chinese medicine hospital, I just have less sun exposure. How can I have the heart and money to buy any cosmetics, if I go home, if you see it in two years, maybe I will be darker than your Yan Peimin. ”

"You're a typical angry young man, I finally know why you can't find a girlfriend. ”

"Why?"

Liu Liping raised her hand and pointed at a few people, and said: "If the water is clear, there will be no fish, and if people are observed, there will be no friends." Not to mention girlfriends, apart from your fox friends and dog friends, you don't have many male friends. Anyway, you're talking about these things as useless, what will I use to put on makeup in the future?"

Xu Yi smiled, this friendship will naturally cost money, how can I have spare money for recreation before, and I can make a few friends with this nod. "It's so easy to have a shadow? I didn't think about it, it was an accident, but I was really curious what it was. ”

Liu Liping looked up at Xu Yi and asked, "Do you think this is not collagen?"

Xu Yi smiled and said, "Yes, I don't think this thing can be gelatin, you wait for me to make a real yàn." Let's take a look outside, Xu Yi walked directly to the terrace and picked up a piece of paper on the ground.

Seeing that several people were a little suspicious, Xu Yi raised the napkin in his hand and said: "This is the small piece that Xiao Liu pulled off before, I put it here to dry it, and it looks like this." ”

A few people took it and looked at it, and saw that a small piece of paper was covered with a thin transparent film.

Liu Liping asked, "What does this mean?"

"I can't explain anything, but we should know if we burn it on fire. Saying that, Xu Yi tore off the small piece of paper, lit it with a lighter, and then smelled the faint smoke coming out, and then explained to Liu Liping: "This thing can't smell the smell of burnt hair when it is burned, so it can be determined that this thing is definitely not collagen, and it may not even contain protein in this thing."
