Neem might help you get a more even skin tone. The antioxidants in neem aid to level out your skin tone by lowering melanin synthesis in your skin. It also lightens dark spots, blemishes, and redness on your skin. Neem's anti-inflammatory properties can also help reduce the appearance of fine lines and wrinkles. Using neem oil regularly can help lighten your skin color. Just like any other medication, there are risks involved with using neem oil so it is important to understand these risks before use. There have been no reports of anyone being harmed by using neem oil but it should not be used by pregnant women or those who suffer from allergies or asthma. The only negative effect of neem oil that has been reported by scientists is contact dermatitis (skin irritation). This has been reported by some users of neem oil after they have been exposed to the pollen from plants that contain high levels of histamine. People who are allergic to pollen may experience this problem when using neem oil on their skin. However, most people report that neem oil is safe for use even by people who are sensitive to other oils and chemicals. If you do encounter problems with neem oil causing skin irritations or allergies, then consider avoiding it.
