When it comes to skincare, we mostly tend to focus on external aspects such as cleansing, toning, moisturisation etc. But just like the other organs of your body, your skin is also affected by your internal health.
Vitamins play a vital role in cell renewal, DNA damage repair, utilisation of other nutrients, boosting the immune system etc. Thus, if your body is low in supply of these essential nutrients, it may show up on your skin as dehydration, wrinkles, or in worse cases, infections.
Here’s the list of vitamins that you can add to your diet to attain healthy and glowing skin. Vitamin A This fat-soluble vitamin is commonly found in the form of beta-carotene in foods as well as supplements. A potent antioxidant, it is one of the most commonly used ingredients in sunscreens, anti-aging serums, moisturisers and so on. Vitamin A not only helps you get well-hydrated, youthful skin but can also help to fight skin issues such as acne.
Benefits Facilitates cell growth and cell renewal which rejuvenates both the upper as well as the lower layers of your skin (dermis and epidermis). Boosts collagen production which smoothens the skin, minimising fine lines and wrinkles. Scavenges the free radicals on your skin thus minimising damage due to the harmful UV rays of the sun. Stimulates the sebaceous glands in your skin to secrete oil thus keeping your skin hydrated. Promotes faster wound healing and boosts the innate immune system of the skin. Recommended Dietary Allowance (RDA) The RDA of vitamin A for a healthy adult is 700mcg for men and 900mcg for women per day.

Benefits Vitamin C is crucial to the proper functioning of the immune system and helps to reduce inflammation. It is also a powerful antioxidant and may help in preventing skin cancer.

The deficiency of these essential nutrients can make your skin dull, itchy, prone to breakouts and infections.
