"Hahaha……"

"We must separate the essence, eyes, face, neck, hands, feet, and body."

Several people nodded.

"Just like pork is sold separately, the price is still different!"

Several people laughed crazy.

"Teacher Qin! If you want to spread these words, Yunhua doesn't want to sell them anymore, right?" Qing Xiang said.

Qin Kong smiled and said, "No, I mean that although the skin on the human body is similar, the skin covered on your body may be good. If the exposed skin is contaminated and damaged, then more protection is needed."

Several people nodded, their words were rough and not rough!

Du Fangzhou said: "It is normal for cosmetics not to absorb. Cosmetics are used to evaporate. Big-name cosmetics pay great attention to the skin feeling. You will feel refreshed after applying it, thinking it has been absorbed. No, it just adds alcohol and silicone oil to accelerate its evaporation."

"Hahaha..." Liang Ange said, "Dr. Du has made me lose confidence in cosmetics again."

"No need." Du Fangzhou said, "The function of skin is defense, not absorption. Moreover, skin cannot distinguish what is good and what is bad. If everything is absorbed, what will the person be like?"

Everyone nodded.

"The skin is provided with nutrients from the inside of the body and blood, rather than absorbed from the outside. Most skin care products only act on the epidermis to help the skin resist damage.

It is necessary to use it, but you don’t need to pursue the claimed effects too much. Moreover, the ingredients that really work are mostly like hormone drugs, penetrate into the skin and interfere with the skin’s own regulation function.

But cosmetics will not label each ingredient, nor will they prompt you the consequences of long-term use. Some ingredients will not be detected."

Qin Kong nodded, and some of the ingredients he measured using the divine principles were not written on the packaging.

Du Fangzhou looked at him, "Teacher Qin! I really admire you! But because the unmarked ingredients you wrote really exist and are really useful, I don't doubt you!

But how did you detect it? The instrument can't detect some ingredients!"

"Well..." Qin Kong couldn't explain, so he quickly turned on his chopsticks, "Eat vegetables, eat vegetables."

Qingxiang laughed and said, "Anyway, I don't care how Teacher Qin detected it, but when President Maggie brags to me that they have 3,000 recipes, I laughed."

Du Fangzhou didn't bother Qin Kong, and ate some food for a while, and said: "Although most skin care products cannot be absorbed, fat-soluble ingredients are indeed more likely to penetrate the skin. Essential oils are fat-soluble."

"Wow!" Liang Ange and Qingxiang's eyes were shining.

"So Yunhua still has an advantage."

Everyone nodded.

"But you can't do whatever you want, and what amount you use. It's not that the more you absorb, the better. Excessive amount also destroys the skin's own function. This is what the R&D and formulators need to do!"

Liang Ange looked at Dr. Du in admiration.

Du Fangzhou looked at Qin Kong, and Qin Kong lowered his head as if he didn't see it. He was really a little scared. This person was too serious!

After dinner, the secretary also came to pick Qingxiang up. Several people said goodbye, and Du Fangzhou grabbed Qin Kong, "Wait!"

He pulled Qingxiang back to Kongfayi, so he asked Qin Kong to come and ask for scissors, and cut off a small strand of hair.

Although Qingxiang felt distressed, she still gave her hair to research and development and said, "Dr. Du, I have 60,000 yuan, how much do you calculate if you continue to take this knife?"

Liang Ange smiled, but Qin Kong was very nervous.

Du Fangzhou also asked seriously: "Is the R&D center still open tonight?"

Qingxiang nodded, "Everyone is busy until late during this period."

"Then I'll go to the test now."

Qingxiang asked the secretary to send Dr. Du to the R&D center first and left together.

Qin Kong watched Dr. Du leave with his hair, but he could not stop him, so he could only wait until he could study it and explain it.

Grab your head and drive home.

Liang Ange looked at him worriedly, "What's wrong?"

“I was wondering how I would explain it?”

"What did you do to be sorry for me?" Liang Ange stared at him fiercely.

Qin Kong was speechless, turned his head to look at her, raised his hand to rub her head, "Okay, I don't want to, you have successfully dispelled my troubles!"

The generals come to block the water and cover the soil. When Dr. Du finishes testing and comes to ask him, he will perform on the spot!
