Microneedling + Hands Q&A

I would like to know if microneedling can be a solution for repairing skin in my hands and neck. What other parts of the body can it be used on.

Thanks to a monster known as early menopause, Ive rapidly aged in just a few short years. Im feeling 10-15 years older than my actual age and want to know, if I can use this, where and how often? How soon for results? Should I get a shorter needle? I found his on a whim and it was the only size available. Thanks

I was wondering if the face is only place that Micro-needling can be done? I was wondering since it produces collagen & thickens up the skin can it be done under chin in the neck area for firming? & also can it be done on back of hands for thinning skin & crepiness or would veins in hands be a problem? I'd also like to know if when used around eyes does it help at all with diminishing dark circles? Thank you

If micro-needling can build up collagen on the face to resurface the skin, can it also be used on thin skinned, aging hands, and lower arms, especially for those who bruise easily in these areas?

After years of sun exposure and cortisone shots for arthritis, the skin on my hands and forearms is very thin and tears easily. I only wear long-sleeved shirts at this point. I've tried every cream, lotion, retinol product, and vitamin protocol available to no avail. Do any doctors think that microneedling and selphyl might help with collagen renewal and thickening of the skin? Thanks.
