Received secret RF twice, the second time left me with pin/grid marks on my right cheek bone five months later. What now?

You need an in person evaluation by a board certified cosmetic dermatologist. There are a multitude of treatments that could help you with this including peels, skin care, medical grade facials, and more. See an expert. Best, Dr. Emer. 

Just based on your two photos, I would suggest treating the area with an antifungal cream to see if you can get some improvement. Your pores look thickened which micro-needles alone should not do. You can also try a small amount of castor oil massaged into that area at night.

Indeed with this type of reaction, a real time examination is best. Many safe ways to reduce the effects from microneedling RF including optimal topicals, small beam lasers like 1927 Fraxel or diode driven 1927 Clear and Brilliant overpass technique, or pico lasers. All the best, Davin S. Lim. Brisbane. Australia.
