Your diet contributes a great deal towards making you beautiful.  
To improve your skin with healthy eating a wholesome diet is essential. It is important to get enough proteins, vitamins and mineral; lean meat, fish, poultry, eggs, fresh vegetables and fruits; avocado, cucumber and cabbage are particularly recommended.  
Poor health habits, too many fats and sugars, too many stimulants like coffee, are bad for your skin: so is smoking.
