For you acne scars, use a 1.5 mm dermastamp with 35 needles.
Use the 1.5 mm dermastamp also for the wrinkles around the mouth.
For the wrinkles around the eyes and for the overall skin texture, buy a regular 0.5 mm dermaroller.
Please read my reply #2 to see how to mcironeedle around the eyes:

Pores are ducts in the skin and their size is genetically determined. There
is currently no method that can reliably and permanently make pores smaller.
Very few of our customers managed to make their pores smaller through
microneedling. You can try a regular 0.2 mm or a 0.5 dermaroller to thicken
the epidermis or a 0.5 mm dermastamp. A thickened epidermis could make pores
look smaller because the pore size is the smallest on the skin's surface and
as you go deeper into the skin, the pore channel widens. Some of our
customers improved their pore size with the single needle but always try
just one pore to see if it is not making it worse. Do not expect results too
soon.
Dermarolling and the use of Retin-A is perfectly OK when you have Lyme disease and scientific principles disagree with the notion that "inflammatory products" are to be avoided with Lyme disease, just like the misguided idea that mushrooms are to be avoided when one has Candida:
