Detailed answer

Constant exposure to dust mites or indoor allergens can potentially aggravate hyperpigmentation. Dust mites and indoor allergens can trigger inflammation and increase the production of melanin, which can lead to further darkening of hyperpigmented areas. Additionally, allergens can disrupt the skin barrier function, making it more vulnerable to pigmentation issues. It is important to minimize exposure to these allergens and maintain a clean and allergen-free living environment to prevent exacerbation of hyperpigmentation.
