Vitamin C is a water-soluble vitamin found in citrus fruits, green and leafy vegetables, and other foods. It is known to protect the skin from ultraviolet B (UVB) damage and enhance collagen synthesis, making it a popular ingredient in cosmetics as a whitening agent, especially in Asia. Vitamin C is also an effective reducing agent that can momentarily retard the melanin-biosynthesis pathway in skin, which can lead to a lightening effect. However, vitamin C tablets do not lighten skin permanently.
There are several other ingredients that are effective in skin brightening supplements, including:
-
Glutathione: An antioxidant that is naturally produced by the body. It has been shown to inhibit melanin production and reduce the appearance of dark spots and hyperpigmentation.
-
Citric Acid: A skin-restoring alpha-hydroxy acid (AHA) that exfoliates and brightens the skin.
-
Zinc: A mineral that is essential for healthy skin and can help reduce inflammation and redness.
-
Ceramides: A type of lipid that helps to strengthen the skin barrier and retain moisture, leading to a brighter and more even complexion.
It is important to note that skin brightening supplements should be used with caution and under the guidance of a healthcare professional, as some ingredients may have side effects or interact with medications.
