Detailed answer

When someone has an allergy to a specific ingredient in skincare products, their immune system reacts and triggers inflammation in the skin. This inflammation can disrupt the skin's barrier function, leading to moisture loss and dryness. Common allergens found in skincare products include fragrances, preservatives, dyes, and certain types of chemicals. It's important to read product labels and avoid using any products that contain known allergens if you have a history of allergies or sensitivities. If you suspect an allergy to a specific skincare product, it's best to stop using it and consult a dermatologist for further evaluation.
