Dark spot corrector is a skincare product designed to reduce the appearance of dark spots or hyperpigmentation on the skin. These spots are usually caused by sun damage, aging, acne scars, or hormonal changes. Dark spot correctors work by inhibiting the production of melanin, which is responsible for the pigmentation of the skin. They typically contain ingredients such as vitamin C, retinol, hydroquinone, kojic acid, arbutin, and licorice extract, which can help to brighten and even out the skin tone.
