Is stem cell skin injection suitable for people with thin skin?

I'm interested in stem cell skin injections, but since my skin is on the thinner side, I'm worried the marks might last a long time.

I'm also curious if people who bruise easily show more visible marks after the procedure.

It seems stem cell skin injections are often used to improve skin elasticity or texture.

I'd also like to know if the injection depth or location can vary depending on skin condition. ㅠㅠ

For those who have received stem cell skin injections, how long did the marks last?
