Hello, I was out in strong sun the 3rd day after microneedling with spf 30 (I forgot about the no sun rule..:(). I am fair skin and freckled. I don't have redness (I am prone to sunburn) but I do have a strange tightness on the right cheek and forehead. What are the concerns of sun after microneedling? Just sunspots hyperpigmentation? Thanks a lot!
