Detailed answer

Cleansers are primarily for removing dirt, oil, and makeup from the skin's surface. Dark spots, also known as hyperpigmentation, are caused by an overproduction of melanin in certain areas of the skin. To effectively treat dark spots, it is necessary to use products that target the underlying cause of hyperpigmentation, such as serums or creams containing ingredients like hydroquinone, niacinamide, or alpha hydroxy acids. These products work by inhibiting melanin production, promoting cell turnover, or reducing the appearance of dark spots over time. While a cleanser can help maintain overall skin health, it is not specifically designed to address dark spots.
