Detailed answer

When makeup applicators are dirty, they can accumulate bacteria, dirt, and oil. When you apply makeup using these contaminated tools, the debris can clog your pores and mix with sebum, leading to the formation of blackheads. It is important to regularly clean your makeup applicators to prevent the buildup of impurities and maintain good skincare hygiene. Using clean and sanitised tools will minimize the risk of blackhead development and promote healthier skin.
