When experiencing an allergic reaction to cosmetics, once symptoms such as localized redness, skin itching, rashes, or blisters appear, discontinue use of any cosmetics that may be causing the reaction immediately. Gently wash the affected area, avoiding hot water and harsh cleansers to prevent further skin irritation.
During the allergic reaction period, reduce outdoor activities and avoid re-exposure to allergens. Diet-wise, consume more foods that help combat allergens, such as broccoli and citrus fruits, and avoid cold foods. Choose skincare products containing soothing ingredients (e.g., aloe vera, oat extract, glycyrrhizic acid) to help alleviate skin discomfort.
Before using a new cosmetic product, perform a patch test on a small area of skin, such as the inner wrist or behind the ear, and observe for 24–48 hours for any adverse reactions. Opt for products with simple formulations, free of fragrances and alcohol, to minimize the risk of allergic reactions.
If the allergic reaction is severe, such as extensive swelling or difficulty breathing, seek immediate medical attention. A physician may recommend antihistamine medications or topical corticosteroid creams to manage the symptoms.
