2, facial skin allergies If it is only mild erythema and itching, you can apply anti-allergic ointments locally, such as weak and medium-effective glucocorticoid ointments, such as Alesone and hydrocortisone cream.

You can also use some non-hormonal drugs, such as tacrolimus ointment and pimecrolimus cream. The effect is also good.
