Skin brightening serums are designed to reduce dullness and discoloration, promoting a more even skin tone. They work by targeting pigmented lesions or skin discoloration, often utilizing ingredients like vitamin C and beta arbutin. However, it's important to note that these serums don't actually "whiten" the skin in the sense of changing its natural pigment. They simply improve the appearance of the skin by reducing unevenness and hyperpigmentation.
For example, vitamin C helps to inhibit melanin production, which is the pigment responsible for skin color. Beta arbutin works by interfering with the transfer of melanin to the skin's surface.
It's crucial to remember that using unsafe or unproven ingredients can lead to serious health problems. Always choose products from reputable brands and consult with a dermatologist for personalized advice.
