Detailed answer

Constant exposure to indoor dust or allergens can exacerbate hyperpigmentation. Dust and allergens can trigger inflammation in the skin, leading to an increase in melanin production and worsening of hyperpigmentation. Additionally, these particles can clog pores and hinder the natural exfoliation process, causing uneven skin tone and making hyperpigmentation more prominent. It is important to maintain a clean indoor environment and minimize exposure to dust and allergens to reduce the risk of aggravating hyperpigmentation.
