Is the white jade injection effective?

I noticed that my acquaintance purchased a package of nearly 20 sessions of the white jade injection and received it every week.

But does the pearl injection really have a good effect of making the face whiter?

Is it really good to get vaccinated consistently every week??

They said it's for administering with an IV in the arm.

I am very hesitant.

I have to get injections every week...

It feels like my blood vessels are about to burst ㅜㅜ
