4. Vitamin H

You might not be so familiar with the name, but you will know Vitamin H as biotin. You probably also associate biotin with hair and nails because indeed, it does promote keratin health, but it is also good for your skin. This is because biotin assists in the production of new cells and helps oil glands function properly. Getting enough biotin definitely help with the healthy condition of your skin. The richest source of biotin is liver but other biotin-rich foods are egg yolks, nuts, seeds, salmon, and dairy.
