Inquiry about the skin booster effect

hello!

It's so cold these days, so I'm curious about the effects of skin booster, so I'm asking~!

My skin is thin and dry ㅜㅜㅜ I don't like things that are irritating and painful

I've never received skin booster treatment before.

How effective is Skin Booster? How long does it last?

I'm curious about information like how many times and at what intervals I should get it periodically.

And for those who have tried the skin booster, which season would you recommend?

I'm also curious about the aftercare laws!!!
