Skin is probably the funniest organ in our bodies. A lot of people don’t even know that skin is an organ, for starters. It’s the only organ that’s readily exposed to the environment. And then, it’s the only organ we might think of more in terms of how it looks than whether it performs its function properly.

The two actually go hand in hand – there’s nothing more beautiful than healthy skin which performs all of its duties properly, and it being that way has to do with some necessary vitamins.

You’ve probably heard of chemical compounds called antioxidants, which play an important role in preventing and fighting damage caused by free radicals. There is a theory that this damage is one of the causes of aging, hence a lot of anti-aging creams have antioxidant compounds in them.

Well – vitamins A, C and E are antioxidants. These vitamins also help skin deal with sun damage, apart from the fact that they have a role in the regular maintenance of the cells that make up our skin. Vitamin C, for example, plays a vital role in collagen formation. Vitamin A, on the other hand, helps the skin cells develop and grow, and it keeps sebaceous gland activity under check. Vitamin E, well, it’s just an anti-oxidizing powerhouse.

And then there’s vitamin K. Vitamin K has several roles in the body, most important of which is probably regulating blood clotting. However, the best known benefits skin gets from vitamin K are those gained when applying it topically. So, vitamin K has been used to treat everything from rosacea, bruising and scarring to stretch marks, and even eye puffiness.

You probably get most of the vitamins you need through your diet, however, supplements are readily available if you think you’re deficient in one or several of them. And while using skin care products with vitamins probably won’t harm you, taking too many oral supplements can be bad for your health, so make sure you discuss your vitamin intake with a doctor.
