Hello,
Facial flushing is a known side effect of using Accutane especially when you do not avoid the sun. Using tacrolimus often resolves the itch, redness, and tenderness but it should be taken after a dermatologist’s guidance. Avoiding caffeine, spicy foods, and alcohol, also may help clear the skin. But if the symptoms persist then IPL treatment and alternate IPL with Nd:YAG 1064 laser may also be required.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
Do use photoprotection since retinoids are known to induce photosensitivity, albeit rarely.
