Hello,
It can be due to dermatitis or rosacea. Rosacea is a cutaneous disorder primarily of the central part of the face , such as forehead; cheeks ;nose; and chin.
Treatment options vary from antibiotic creams, antihistaminics, sun screens to laser treatment. A dermatologist’s evaluation will be the best.
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.
