What is the most effective way to minimize pores or eliminate the look of large pores?

It really depends on the size of your pores and your expectations. Micro needling is one on the many treatments one can use to decrease pore sizing. 
Microneedling has come a long way over the past few years and can help skin via several methods. Firstly it releases cytokines and growth factors in the epidermis and dermis- the top and bottom layers of your skin. This in turn remodels scars and the dermal layer of the skin. Additionally needles can break up scars themselves. This leads to new collagen formation.

 
Microneedling is both user dependent and method driven. Simple needles can be used, growth factors can be added after the procedure, including PRP, or controlled heating during the procedure. This controlled heating is delivered via RF, and is called RF microneedling. RF can then be delivered via insulated or insulated needles. Even the energy level, depths, density, pulse duration and so many other variables can be controlled. This together with the added benefits of growth factor infusion makes this one of the most complex procedures in procedural dermatology. I use everything from Dermapen, though to newer generation insulated and non-insulated devices including INFINI micro-needling radiofrequency, Intensif and others. Newer generation devices can provide an added advantage in some, but not all patients. Like most procedures, its 80% skill level of the specialist and 20% dependent on the brand of the energy device- microneedling system. 

Thanks for the great question. Microneedling is very safe at your age and the results can be impressive. The recovery time with micro needling is very fast with very little social down time. Most people could get the procedure done at lunchtime and with Oxygenetix post procedure foundation go back to work, or the grocery etc with out it being extremely noticeable. Most people say it looks like a sunburn or wind burn. Within 3 days most people are almost back to normal and the results are on going for about 6 months. Good luck.
