5. Vitamin B12
In case you suffer from chronic skin problems or in case you get a dull and unhealthy complexion, you may experience a deficiency of vitamin B12. Vitamin B12 also helps in controlling the skin oil, healing damaged skin and maintaining skin tone. This is because it helps to manage the skins pigment, thus preventing hyper-pigmentation, which leads to excess darkening of the skin. Besides, one of the features of vitamin B12 is its possibility to maintain a youthful skin. We all love the smooth skin, but a deficiency of vitamin B12 can result in premature lines and wrinkles. Vitamin B12 is found in liver, eggs, meat, shellfish, muscle meat, cheese, and fish.
