4 months post facial nevus removal I now have cysts, grains and encysted hairs. What can I do? (photos)

Thank you for your question and photographs. Unfortunately, it's difficult to evaluate and diagnose your skin through this type of forum. Cysts, acne, ingrown hairs could be possibilities but an in-person evaluation is needed. I highly recommend you consult with a board certified dermatologist to have your skin evaluated and to discuss treatment options that best suit your needs and skin. Take care and good luck.
