I'm 38 years old, generally look good for my age. I've been interested in exploring ways to rejuvenate my face (minor sun damage, fine lines) beyond basic skincare and I've seen some impressive results with microneedling. Noticed a switch from Dermapen to Procell Stamper- which is more effective with less downtime? Also I'm seeing conflicted views about how deep needles need to penetrate to have a true impact on stimulating fibroblast and collagen synthesis. Would love your thoughts! Thanks.
