Swollen face with itching sensation is actually a skin allergy that may be caused by the application of special items on the face, such as skin care products and cosmetics, or during the change of season, due to pollen, or due to an allergic condition caused by ultraviolet stimulation of the skin after sun exposure. With the swelling and itching of the face, it may continue to develop, some patients may spread from the face downward, and localized skin may also appear like a distinct wind-blown tissue, or the symptoms on the face may continue to worsen, such as the occurrence of significant dryness of the skin, or even the appearance of swollen skin bumps, accompanied by significant oozing of fluid. In this case, anti-allergic drugs such as loratadine, cetirizine, and oral or intravenous glucocorticoids should be applied immediately to provide a clear relief.
