There are many natural options available to treat hyperpigmentation and uneven skin tone. Licorice extracts, such as liquiritin and glabridin, have been shown to be effective in treating uneven skin tone. Niacinamide is another common ingredient used to even out skin tone and brighten skin. Niacinamide is a B vitamin that prevents pigment from being transferred into skin cells. Like Niacinamide, soy prevents pigment transfer and is very well established as a treatment for uneven skin tone. Vitamin C is another well-known vitamin to help with uneven skin tone and dark spots. A natural fruit extract, called emblica (also known as Indian gooseberry), has been shown to improve hyperpigmentation and even the skin tone. Other natural agents, including pomegranate extract, acerola fruit extract, and aloesin (derived from the aloe plant), have been shown to have some efficacy in improving skin tone. This is an extensive list and I am sure you must be wondering which works best. Well, a combination of these ingredients seems to be the most effective. When combined, these ingredients are significantly more effective than when used alone. The best approach is to look for multiple ingredients in products, and to look for studies that show that a treatment actually works. With this approach, you can be more confident in choosing a skin brightener.
