Detailed answer

Certain makeup products contain ingredients like heavy oils, silicones, or fragrances that can clog your pores, causing your skin to look dull. Additionally, some makeup products may dehydrate your skin, leading to a lack of moisture and a dull appearance. It is important to choose makeup products that are non-comedogenic and labeled as suitable for your skin type to avoid clogged pores and dryness. Regularly exfoliating your skin and properly cleansing your face before bed can also help remove any leftover makeup residue that may contribute to dullness.
