The skin, the outermost layer of the body, is the first line of defense against external factors like the weather, dust, or harmful microbial agents. For it to function smoothly and efficiently, it requires a steady supply of a number of essential nutrients and vitamins.

Vitamin A
It is an essential vitamin that prevents the breakdown of collagen present in the skin due to the harsh rays of the sun. By interrupting this process, it offers protection against sunburns and is also an antioxidant. Vitamin A also plays an important role in the functioning of the oil glands present around the hair follicles. It is also known to be beneficial during the healing process of lacerations and wounds. Depletion of these skin vitamins in the body causes the skin to feel dry and irritated.

Vitamin C
This vitamin is crucial in the stabilization of the protein called collagen in the skin. Since it is an extremely powerful antioxidant, it protects the skin from free radicals and lowers the chances of developing skin cancer. Deficiency of this skin vitamin can slow down the process of healing cuts and sores on the body and can even lead to bleeding gums.

Vitamin E
Vitamin E is an important and multifaceted class of vitamins. It works in conjunction with Vitamin C to strengthen the cell walls of the skin. Being a powerful antioxidant as well as a potent anti-inflammatory agent, it can prevent harmful ultraviolet radiation from the sunlight. In the absence of these skin vitamins, this UV radiation can cause damage to the skin and lead to the formation of wrinkles. In extreme cases, it can even lead to skin cancer.

While not exactly classified as vitamins, there are a few other components that help the skin. They are:

Proteins
The protein obtained from the food we eat is broken down into amino acids, which are then evolved into more proteins. These secondary proteins are essential for the skin as it helps in the functioning of the skin cells, and keratin, which nourishes the hair, nails, and protects the skin. They are also beneficial in the disposal of old skin cells and protects the skin from harmful ultraviolet rays.

Zinc
It is an important mineral that helps with the healing process of the skin. While playing a major role in the stability of cell walls in the skin, it is also an essential component for the cells to divide and specialize as they grow. Zinc acts as an antioxidant and also provides a modicum of protection against the sun’s harmful ultraviolet rays. A deficiency of this mineral can cause skin rashes that are red and irritated.

There are a lot more vitamins and minerals that aid the functioning of the skin and help protect the body. You can usually get your daily requirement of vitamins to help your skin from foods like fruits and vegetables. However, some foods can have a combination of these vitamins, like eggs, legumes, and extra-virgin olive oil. Fruits and vegetables are filled with essential nutrients for the skin and are the best foods for skincare.
