It's called the skin vitamin for good reason—doctors love it, it is a vital part of any conversation about bright skin, and without a few (or many) drops of it, flawless skin might just be a distant dream. Vitamin C is that wonder vitamin that not only fights cold and flu from the inside, but also defends skin against dark spots, signs of ageing and sun damage when applied topically. It also boosts glow and evens out your complexion. How does it do all this? We asked celebrity dermatologist Dr Geetika Mittal Gupta, founder and medical director of ISAAC (International Skin & Anti-Aging Centre) in Delhi to tell us more about the miracle vitamin that can make your skin cross over to the bright side.

## What exactly is Vitamin C? How does it work on your skin?

[Vitamin C](https://www.vogue.in/content/skincare-alphabet-v-vitamin-c/) (L-ascorbic acid) is a water-soluble vitamin. It's a powerful antioxidant present in both the epidermis and dermis of the skin. As it's water soluble, it's not stored in your body in significant quantities and the excess that is consumed gets eliminated through the body. This is also why regular replenishment is important. As an antioxidant, Vitamin C neutralises free radicals in the skin. It is anti-inflammatory, so it heals and hydrates the skin too. It also has an anti-ageing effect as it boosts collagen production, which in turns helps to reduce the formation of wrinkles.

## Why should I use Vitamin C?

Vitamin C application has been known to improve fine lines and reduces both pigmentation and inflammation. The vitamin also empowers skin with potent antioxidant activity, which helps neutralise the oxidative stress developed due to various environmental stressors and pollution. You can use it for photo protection as well—it's equally effective against both UVA and UVB damage and to ward off pigmentation. Vitamin C works beautifully on pigmentation and uneven skin tones as it inhibits the tyrosinase activity (oxidation), thus decreasing the melanin production.

## What role does it play in correcting sun damage?

If retinoids are the gold standard then Vitamin C is the silver standard for reversing photo-ageing of skin. Although Vitamin C in itself is not [sun protective](https://www.vogue.in/content/everything-you-need-to-know-about-protecting-your-skin-from-the-sun/), topical application protects you against the photo damage. The vitamin works by deactivating UV-induced free radicals.

## What's the best way to store and preserve Vitamin C?

Vitamin C is water-soluble and oxidises easily when exposed to air (oxygen) and loses its effectiveness. Store it away from light in a dark corner. When buying a Vitamin C serum, look for ones with additional antioxidants like [Vitamin E,](https://www.vogue.in/content/benefits-of-vitamin-e-how-this-magic-ingredient-works-for-your-skin) ferulic acid or alpha lipoid acid, these help in stabilising the formula.

## Is there an order in which Vitamin C should be applied?

After gentle cleansing, pat toner on the face. Let it dry and then apply Vitamin C with fingertips on the face and neck. Let it get absorbed and lock it in with a moisturiser, followed by a [sun block](https://www.vogue.in/content/sunscreen-lotion-how-to-use-sunscreen-your-ultimate-guide-to-sun-protection/) before stepping out in the sun. You can use it only during the day if photo damage is your major concern or you can use it at night, if restoring the skin and anti-ageing is on your agenda. Always use it before you apply any makeup.

## What ingredients are safe to use with Vitamin C?

— Vitamin E: It increases the effectiveness of Vitamin C fourfold by acting on different compartments of the skin cells when used together. This combination is also good because Vitamin C can regenerate oxidised Vitamin E, which acts as the front-line defence against UV-radiation-induced free radical damage.

— Ferulic acid: Some studies indicate that it can increase the effectivity of Vitamin C and E by eight times, and it also helps in stabilising the antioxidant effect of a mix of Vitamin C and E. This triple antioxidant combination is available in C E Ferulic, a product by Skinceuticals.

## Which ingredient should never be mixed or worn with Vitamin C?

Retinol and Vitamin C should not be mixed together because retinol is best absorbed at a pH of 5.5-6 and vitamin C at 3.5 or lower. Therefore, the efficacy of both ingredients decreases when used together. They should preferably be used at different times of the day.

## Should I be popping a Vitamin C pill too?

Vitamin C plays an important role in our body. It's needed to maintain the health of skin, cartilage, bone, and blood vessels. It also protects body cells from damage due to its powerful antioxidant nature. It is necessary for collagen synthesis, and higher intake is associated with better skin appearance. Normally people get enough Vitamin C in their diet; however, a low dose of Vitamin C can result in a medical condition called scurvy which can present itself as a rash, muscle weakness, tooth loss or [joint pain](https://www.vogue.in/content/the-oil-thats-being-used-for-everything-from-joint-pain-to-cancer/), among others. I recommend a 500 mg dose twice daily.
