Thinking of this, Qin Jian thought of another thing.
When she was in the secular world, she was a member of the component party, but she particularly liked a component, what was it called, she forgot it at the moment.
That’s right, it’s called niacinamide.
This ingredient was relatively well-known among skin care ingredients at the time, and it was the best in terms of comprehensive efficacy.
Niacinamide is a form of vitamin B3 with a small molecular weight and is easily absorbed. Many major brands use it, and it's particularly popular with those with oily skin types, who often experience oily skin, dull complexion, enlarged pores, and rough skin.
Overall, niacinamide is very good, but it is not very friendly to sensitive skin, and some people are intolerant to it.
The amazing thing is, if you want niacinamide to achieve a certain effect, you must reach a certain concentration.
For example, oil control.
This needs to reach a concentration of two percent. After a few weeks of use, the effect will be more obvious. Niacinamide will regulate the oil secretion of the skin to a reasonable level and will not cause any disturbance. With less oil secretion, the pores will appear smaller.
For example, brightening the skin tone.
This also needs to reach a concentration of two percent.
Niacinamide is not just for whitening. Its whitening method is different from arbutin. Conventional whitening ingredients inhibit tyrosinase, preventing the basal layer of the skin from producing new melanin. After the old skin is replaced, it looks white. However, niacinamide cannot prevent the production of melanin. Instead, it prevents melanin-containing cells from metabolizing upwards, allowing other cells to move upwards, making the skin look whiter.
When some melanin escapes, niacinamide accelerates the renewal of skin cells and promotes the shedding of melanin-containing cells. After several skin metabolism cycles, the skin tone becomes brighter.
Then there is oxidation and glycation, both of which can cause yellowing of the skin. At this point, because niacinamide is an antioxidant, it can effectively prevent cells and cell membranes from damage by free radicals and eliminate free radicals. It can also inhibit yellowing of the skin and inhibit protein glycation.
For example, acne treatment.
For acne treatment, a 4% concentration of niacinamide is required. A 4% niacinamide gel is more effective than clindamycin in removing acne. It also has anti-inflammatory properties, and long-term use won't cause bacteria to develop drug resistance. Because of its whitening and anti-inflammatory properties, niacinamide is also very friendly to new acne scars.
Such as anti-aging, improving skin quality, and repairing skin barrier.
Anti-aging generally refers to both antioxidant and anti-glycation properties, both of which niacinamide possesses. Improving skin texture is achieved by accelerating epidermal renewal and providing gentle exfoliation, ensuring that the old doesn't go away before the new arrives. A damaged skin barrier can lead to acne, and an oily exterior and dry interior are also signs of a damaged skin barrier. Niacinamide can increase the synthesis of ceramides, fatty acids, and cholesterol in the epidermis—the three essential components of the skin barrier.
It is worth mentioning that the higher the concentration of niacinamide, the more irritating it is. Start with a low concentration and gradually increase the concentration after building skin tolerance.
If she remembered correctly, these things existed in the secular world in her memory, such as the 4% niacinamide gel at the Nanjing Chinese Academy of Medical Sciences Dermatology Hospital, and the compound niacinamide gel at the Guangdong Provincial Dermatology Hospital.
What’s interesting is that at that time, the same ingredients, added flavors and pigments, etc., sold for hundreds of dollars in big brands, but the concentration was not as good as the eight yuan sold in the hospital. Although the concentration was not as high, the price was reasonable, and there was no need to worry about the hormones, heavy metals, lead and mercury in small brands.
Qin Jian put the food down after he was full. The two guys seemed a little restrained and didn't even eat the side dishes, so he simply asked them to pack up and take it back.
"Really?"
"real."
"Then I'm not welcome. I really am not welcome."
"Okay, I understand."
This conversation and the act of sharing food moved Qiu Haoyan so much that his eyes were filled with tears.
At this moment, no words can express his wonderful mood.
He rushed over and said, "Okay, okay, good brother, we will be good brothers for life!"
Qin Jian, who escaped the tiger's embrace: ...
Who the hell is this, brother!
Chu Yuan was not polite. After he tidied up the things quickly, he handed something to Qin Jian. Before she even looked down, the two men left.
Uh, military emergency rescue device.
So generous.
However, Qin Jian didn't really need it. She just wanted to destroy it to prevent it from dropping accidentally and hurting someone in the hands of others. But when she was about to do it, Qin Jian paused, and finally put it away carefully. After all, this was someone else's gift, so she had to keep it carefully.
In fact, Qin Jian had a good impression of Chu Yuan. Although he was a cold and quiet person, he always felt familiar with him.
She remembered that she was actually quite stupid when she was young.
One time her soul mistakenly entered another place and she forgot who she was. She cried like an ordinary child, looking for the little brother in green clothes. Then the little brother, who looked like he had just graduated, was busy coaxing her all day long and even took her to buy food.
Unfortunately, I never saw him again.
As soon as the thought passed, Qin Jian began to pack up and prepare to rest.
I have to say that the scenery here is quite good.
The other side.
Chu Yuan also had a good impression of Qin Jian, but before he could figure out what was going on, the two of them were knocked down by their teammates who suddenly appeared and were supposed to be on patrol.
"Ahhh, give it back to me--" Qiu Haoyan screamed.
"We're all brothers, don't be stingy! It's not good to be stingy! Tsk, it's really delicious! You can't eat alone..."
"It smells so good, it smells so good, it's absolutely amazing, let me try it first..."
"I saw you guys sitting over there eating a while ago. Do you know how long we resisted rushing over? It smelled so good, and yet I was able to hold on and not go over. I'm really impressed by my own willpower."
"Hey, hey, hey, don't run. I'm still here. Leave some for me, you bastard..."
The minority cannot beat the majority, and in the end Qiu Haoyan only managed to snatch back a few strips of meat and stuff them into his mouth. He looked at those guys depressedly as they ate the meat crunchily, sometimes doing this, sometimes doing that, simply showing off. But the key point was, the things being shown off were his!
So angry!
Chu Yuan was fine. He ate quite a bit during the melee, so it was still okay.
college.
When Chen Ying discovered that Qin Jian had left him and gone off to play somewhere, he was furious like a little baby and exploded with rage...
