We have to take food supplements in Pakistan such as vitamin A, omega, and vitamin C (key ingredients for the beauty of the skin), because their intake is insufficient in our daily diet. You can always try to eat fish at every meal, raw (not) liver two to three times a week and squeeze oranges at every meal, you might get the number of nutrients you need, only these won't necessarily be absorbed by your body. Whose fault is it? lifestyle, intestinal problems, alcohol, caffeine, and smoking, which can damage the quality of the nutrients you ingest. By taking food supplements you ingest all the necessary needs for your skin in one go. Smart no?
