Vitamin C is an essential nutrient that helps our body perform basic everyday functions and our skin stay firm and supple, preventing against the effects of aging.
It's quite common to hear false beliefs about this very important vitamin. For example, you often hear that vitamin C is associated with the consumption of oranges... but it's found in many other foods, too. Remember the human body does not produce vitamin C, which is why we need to get it from external sources, basically through foods that contain it to cover our body's requirements.
Vitamin C, also known as ascorbic acid, is an essential nutrient, i.e., something the body cannot synthesise. That's why we have to ingest or absorb it to be able to use it in many metabolic reactions and physiological processes.
It’s also important to mention that it is a water-soluble vitamin and is heat-sensitive. Lack of vitamin C causes a disease called scurvy.
It plays numerous functions within the body and helps in many processes, engaging in immune system processes and energy cycles during physical exercise, helping to reduce muscle tiredness. It also aids in iron absorption. Plus, it plays an important role in the skin, helping to synthesise collagen and delivering a powerful antioxidant effect.
Vitamin C applied topically to the skin is a very effective antioxidant in the prevention and treatment of the aging process. It helps protect our skin from oxidative stress by neutralising free radicals.
It shouldn't be associated with sun exposure because vitamin C is unstable to sunlight, when its antioxidant properties decline. If you enjoy sunbathing, we recommend you use a sunscreen suitable for your skin type and avoid products that contain vitamin C.
