Seborrheic dermatitis is a common condition in facial areas that may present with similar symptoms, as noted by the National Institute of Health 2
Possible secondary bacterial infection should be considered if crusting is present, according to the Centers for Disease Control and Prevention 3

For mild to moderate inflammation, the American Academy of Dermatology recommends hydrocortisone cream 1% applied 3-4 times daily, with a strength of evidence rated as high 3, 5
The use of medium-potency topical steroids like prednicarbate cream 0.02% may be considered for more severe cases, with a strength of evidence rated as moderate 3, 5
Limiting the use of topical corticosteroids on facial skin to short periods (1-2 weeks) is advised to avoid skin atrophy, as recommended by the British Association of Dermatologists 4

Polidocanol-containing lotions may soothe pruritus, according to the European Academy of Dermatology and Venereology 1

Non-sedating oral antihistamines (cetirizine, loratadine, fexofenadine) may be used during the day to relieve itching, as recommended by the American Academy of Allergy, Asthma, and Immunology 1
Sedating antihistamines (diphenhydramine, clemastine) may be used at night to break the itch-scratch cycle, with a strength of evidence rated as low 5

Using the fingertip unit method for topical medication can ensure the appropriate amount is used, according to the British Association of Dermatologists 4
