What should I do for facial skin allergy with redness and swelling?

It is recommended to immediately discontinue the use of any cosmetics or skincare products that may be causing the allergic reaction. Try the following measures to relieve symptoms: cleanse the skin with a gentle, fragrance-free, non-irritating facial cleanser. Avoid washing with hot water, as it may worsen skin allergy symptoms. Apply an ice pack or a damp, cool cloth gently to the affected, red, and swollen areas to help alleviate discomfort. Avoid contact with substances that may trigger allergies, such as cosmetics, perfumes, and cleaning agents. Antihistamines may help reduce allergy-related symptoms such as redness and itching. If symptoms persist or worsen, seek medical attention promptly.
