"Tenders the skin, that is, achieves a firming effect."

After saying that, Su Beiqi suddenly realized something, looked up at Qin Tian, ​​and said, "Do you think there is a problem?"

Su Su also frowned and looked over.

Qin Tian smiled slightly and said: "I know that tannic acid ointment has analgesic, hemostatic and antibacterial effects."

"But you are making cosmetics now. Do you think too much tannic acid is appropriate?"

"Women regard softness as their beauty. I think they don't want their skin to become hard, right?"

Su Su's eyes lit up: "What do you mean?"

Qin Tian smiled and said: "Biology includes plants and animals. Your biological cosmeceuticals are too obsessed with plants."

"Why not consider animal elements? For example, use pearl powder or silk powder instead of gallnuts."

"Pearl?" Su Su slapped the table: "Yes!"

"Why didn't I think of this?"

Su Beiqi also said excitedly: "If we want to reduce costs, we can use silk."

Su Su smiled and said: "Second Grandpa, let's follow this recipe and make some samples as soon as possible!"

After she finished speaking, she remembered, looked at Qin Tian, ​​and said, "You not only know acupuncture, but also Chinese medicine?"

Qin Tian smiled and said, "I just thought of it when I saw some pearl silk masks on the market."

"What do I know? Wife, you and the second grandfather are the real masters."

Su Su took a sip and said, "Don't flatter me!"

"The pearl silk mask is only for women. You can't tell. Qin, you know women very well."

"The prodigal son!"

"I——" Qin Tian looked confused.

Su Su laughed and was about to make samples with Su Beiqi. Suddenly, the door of the laboratory was kicked open, and Su Beishan appeared at the door with a cane.

Behind them are Su Wencheng and Su Nan.

Su Su was stunned for a moment, and her face darkened.

She thought that after what happened yesterday, Su Beishan and the others were here to apologize.

At the same time, she shamelessly requested to join the medical consortium led by her mother.

She secretly made up her mind that this time, she would not forgive them easily.

Now, she has thought clearly about the reason why the Su family was so good to their mother and daughter before anything happened to her.

On the one hand, it's because Yang Yulan's company is very profitable, so it subsidizes them a lot.

On the other hand, they hope to sell their beauty at a good price so that they can climb high in the future.

And when their mother and daughter have no use value, their performance is their true face.

Unexpectedly, Su Beishan said loudly: "Su Su, I will give you one last chance to return this factory to me!"

Su Su said excitedly: "This is impossible!"

"For my father's sake, I don't want to argue with you!"

"Now, please leave!"

Su Beishan said angrily: "Evil obstacle!"

"In that case, don't blame me for being unkind!"

"I now officially announce that because you are rebellious and betrayed the family, I will use my status as the head of the family to expel you from the Su family!"

"From now on, the Su family has nothing to do with you."

"What did you say?" Su Su was stunned.

Being expelled from the Su family did not cause any real harm to her. However, I have to say that this was a very big humiliation!

A person, even her family does not recognize her, what will others think?
