Detailed answer

Yes, hyperpigmentation can be caused by allergies. When the skin is exposed to allergens, it can trigger an inflammatory response which can lead to an increase in the production of melanin, the pigment responsible for the color of our skin. This increased melanin production can result in patches of hyperpigmentation. Allergies such as contact dermatitis or allergic reactions to certain skincare products or medications can contribute to the development of hyperpigmentation. It is important to identify and avoid the allergen causing the reaction in order to prevent or minimize hyperpigmentation. Additionally, using sun protection and seeking appropriate skincare treatments can help reduce the appearance of hyperpigmentation caused by allergies.
