Follow the steps for your skin type or skin concern.
Allergic reactions occur when our skin encounters a particular ingredient or combination of ingredients, and it could be any allergen, from dust to mites and plant pollen. At that point the immune system decides whether or not it should accept, reject, or ignore the substance. If the body determines that the substance is unwanted, even when no allergic response existed before, all of a sudden it produces histamines to get rid of it.
Reactions can be subtle, such as a little itching, minor redness and swelling, or small, rashlike pimples. They can also involve a full-blown flare-up that causes intense, but temporary, discomfort and an unsightly appearance, and can even trigger a chronic condition requiring medical attention. If you have a tendency toward allergic reactions, your skin’s condition can be greatly affected and you will have to pay close attention to what you use. Someone with allergy-prone skin needs to use fewer products, and the products should have shorter ingredient lists.
