Skin lightening products are cosmetic formulations designed to reduce the pigmentation of the skin, often targeting dark spots, uneven skin tone, or hyperpigmentation. These products typically contain active ingredients such as hydroquinone, kojic acid, or arbutin, which work by inhibiting melanin production in the skin. While many people use these products for cosmetic reasons, it's important to note that some skin lightening agents can have side effects, including skin irritation or increased sensitivity to sunlight. Users should consult with a dermatologist before starting any skin lightening regimen to ensure safety and effectiveness.
