Detailed answer

If you have an allergic reaction to a skincare product, the most important step is to stop using the product immediately. Carefully wash your skin with a mild cleanser to remove any traces of the product. To alleviate discomfort, apply a cold compress or take an over-the-counter antihistamine. Keep an eye on the reaction for any worsening symptoms, such as difficulty breathing or swelling, which may require immediate medical attention. It's also important to identify the ingredient that caused the reaction to avoid similar products in the future. If the allergic reaction persists or worsens, consult a dermatologist or healthcare professional for further guidance and treatment options.
