It sounds like allergic contact dermatitis. Avoid using any lotions and creams over the face for the meantime. Wash your face with a mild cleanser with moisturizing properties like Cetaphil. Pat your face dry. Then apply a good hypoallergenic moisturizer over the area and see if this improves.If the symptoms still persist then you can apply mild steroid like dermacort.For the itching you can take some antihistaminics like Benadryl or Claritin.Also check your scalp for dandruff as it may clog the pores and cause folliculitis and itching.
If the symptoms persist then it will be best to get it evaluated from a dermatologist. I hope that helps. Please do keep me posted on how you are doing or if you have any additional queries. Kind regards.
