How painful is the skin booster that relieves internal dryness?

Perhaps because of the dry weather, my face feels tight even after applying plenty of basic skincare. So, I am considering getting a skin booster treatment, which is said to hydrate the skin from deep within. However, I tend to be a bit of a wimp, so I am worried about how painful it will be when the booster is injected. I am wondering if the treatment will be bearable if I apply numbing cream thoroughly. I would appreciate it if you could recommend a type that doesn't cause severe pain or leave an embossing effect. I look forward to hearing valuable answers from those who have experienced this firsthand. I am also curious if I can return to my daily life immediately after the procedure. They say you get prettier the more it hurts, but less pain is definitely the best!
