A whitening set typically refers to a collection of products that are designed to help lighten or whiten the skin. These sets often include multiple items such as creams, foam, serums, toner pad , or cleansers that work together to improve the complexion and reduce the appearance of dark spots, hyperpigmentation, or other skin discolorations. Whitening sets may also include additional skincare products such as toners or moisturizers to complete the skincare routine. It is important to note that the term "whitening" in skincare often refers to brightening or evening out the skin tone, rather than permanently altering the natural skin color.
