Vitamin C is essential to our very survival, yet it is a vitamin we are unable to produce ourselves. We must therefore introduce the vitamin to our bodies regularly through fresh fruit and vegetables, certain meats or in supplement form.

Vitamin A is found in nutritious foods such as sweet potatoes, spinach, apricots and liver, and plays an essential role in night vision, bone growth, reproduction and skin health. Skin suffering from vitamin A deficiency falls prey to photo damage, destruction of collagen and elastin - all of which result in dry and ageing skin. By boosting vitamin A levels, the rate of skin turnover is increased and collagen production promoted, lending a more supple, youthful appearance to the skin.

Vitamin C is essential to our very survival, yet it is a vitamin we are unable to produce ourselves. We must therefore introduce the vitamin to our bodies regularly through fresh fruit and vegetables, certain meats or in supplement form. Vitamin C is necessary for the production of collagen, the essential building block of skin. Collagen fibres riddle our bodies, providing firm but flexible structure, and their health is one of the most important factors in determining the appearance and integrity of our skin.

Vitamin E, as discussed above, helps promote clear and flexible blood vessels that allow the passage of oxygen-rich blood to the heart and throughout the body - especially the skin. Vitamin E protects the skin from sun damage, reduces the appearance of fine lines and generally improves skin smoothness.
