Detailed answer

Certain skincare products may contain ingredients that can disrupt the skin's pH balance and strip away its natural oils, resulting in a dull appearance. Harsh cleansers, exfoliants, or products with a high concentration of alcohol can be particularly damaging to the skin's moisture barrier, leading to a lackluster complexion. Additionally, some skincare products may not be suitable for your specific skin type or may cause irritation or inflammation, which can also contribute to dullness. It is essential to choose products that are appropriate for your skin type, avoid over-exfoliating, and ensure you are adequately hydrating and moisturizing your skin to maintain its healthy glow.
