If you’re looking for a way out, then vitamin C serums can be a very useful tool for you in maintaining your oily skin. Today we’ll be answering some of the common queries regarding vitamin C serum and how to use it in the right manner.

Should you use vitamin C serum for oily skin?

First of all, knowing vitamin C serum benefits will help you make your decision firmly. If you are using a good quality vitamin C serum, you will be pleasantly surprised to the see the results we can assure you on that! The list of vitamin C serum benefits can go quite long. Here we have tried to discuss some of the notable ones:

Healthy skin

Vitamin C serum indirectly increases the production of collagen fibers suitable for healthy and firm looking skin. Pollution and wrong food habit can lead to a decrease of collagen production in the skin. This makes your skin lose the firmness and rigidity that it’s supposed to have. A healthy skin requires at least 70 percent of collagen. Vitamin C serum ensures that your skin is enriched with the right proportion of collagen to keep it firm and fresh.

Sun damage protection

With oily skin, finding an ideal sunscreen is the toughest job. Most of the sunscreen creams or lotions make the skin even oilier which can make you quite uncomfortable when going outside.

Vitamin C serum actually provides sun protection for a minimum of 24 hours. In fact, if you have scars due to sun damage or harmful UV rays, vitamin C serum helps in removing those as well. The anti-oxidizing feature of vitamin C serum actually protects your skin from prolonged sun damage.

Skin hardening prevention

Skin hardening is often termed as skin ‘glycation’. The condition occurs due to the reaction of various carbohydrates in the skin, it decreases the important nutrients required for your skin making it hard and susceptible to skin problems. As we’ve already mentioned vitamin C creates collagen.

Collagen content neutralizes the effect of glycation and helps in making your skin look beautiful as ever. Here’s a pro tip: you can keep your skin smooth and fresh for a long time if you avoid nicotine and caffeine in your food habit.

Lengthens younger looking skin

It is quite natural that once you start to age, your skin does not remain the same anymore. Our skin loses its glaze and signs of ageing appear in various forms of wrinkles and pigmentation. In fact, even if you at your prime age, pre-mature wrinkling is a great problem for oily skin if not managed properly. The reasons behind it could be pollution, smoking, unhealthy food habits and many more.

Vitamin C serum can help mitigate the aging skin hazards. How? Well, it produces the right amount of collagen content that your skin requires. The anti-oxidant properties help to keep the skin firm for a longer period of time making your skin look younger naturally.

How to use Vitamin C serum?

Does vitamin C serum really work? A common query among people who want a solution to their oily skin. We can assure you that the product will work out for you if you use a good quality product and more importantly, use it in the right manner.


You should always keep in mind how often to use vitamin C serum to get the desired results. For oily skin, the frequency of usage can be twice a day, although we would recommend that you use the serum at night right before going to bed. Consistency is the key here if you really want to see visible results.


washing face

You need to exfoliate your skin first so that the serum can penetrate into the skin easily. Wash your face with a gentle face wash, face scrub or your regular cleanser. We are not recommending any specific product for washing your face because everyone is unique.

But in general, we do suggest you use a mattifying deep cleansing face wash and exfoliate thoroughly to remove some of the excess oil. Wash the skin thoroughly and let your face stay wet for a while before you gently pat off.


Use your regular toner to tighten down the pores of your skin. Since you will be using the serum afterward, a non-alcoholic toner is better to use in this case. Pro tip, toner that has witch hazel present in it will accelerate the process of vitamin C serum benefits.


After the toning, apply the vitamin C serum on your face and massage all the areas slowly with your fingertips. Keep the serum on the face for a period of 5 to 8 minutes. You need to give enough time to the serum to get into the skin pores and do their job. Removing the serum before the completion of 5 minutes might not be a wise task to do.


Next you apply your moisturizer, face cream or night cream and you are good to go. The process is actually quite simple and would take you a maximum of 30 minutes. We feel if it can make your skin look healthy, it’s a wise decision to make.


You should store the serum in a cupboard or fridge to sustain the anti-oxidant properties for a long time.
