When it comes to dealing with sensitive skin, we know how difficult that can be. You need to be careful about what kind of makeup you are using starting from concealer to lipstick. And not just that, when it comes to using any type skin care products, you have to extra careful with the ingredients since even one odd component might end up being the cause of severe irritation.

So what makes our skin sensitive? Well, our skin has a natural barrier. For some the barrier is strong, but for others not so much. The barrier function may get damaged due to many reasons, starting from extreme sun exposure to stress, dehydration and chemicals from our skin care products. The nerve endings act up when irritated and we see redness or rashes. But these symptoms vary per person.

Common Questions Regarding Vitamin C Serum Usage

We hear plenty of confusions regarding the vitamin C serum usage. Here we have tried to answer some of the common FAQs.

Frequency of vitamin C serum usage

Not just for the sensitive type of skin but for all types of skin, usage rate is important to know. So, how often to use vitamin C serum? With sensitive skin, the best way is to use it once a day only. You can also choose to apply on alternate days. Using more than once is a strict no from dermatologists for the sensitive skin. That will actually cause you more harm than good. We would recommend that when the serum turns brown, you should discard it and get a new one.

Results of using vitamin C serum

Does vitamin C really work? The problem with sensitive skin is that you don’t have the liberty to test any type of new product unless you are absolutely sure about it. Fortunately, the answer to the questions is yes. Vitamin C serum works wonders with sensitive skin if the right application method is used and used at regular intervals. Within months of usage, you will find that your skin is younger looking and becoming firm each day.

For soft and sensitive skin, premature wrinkling is an issue. With using vitamin C serum, you can actually stop that. The serum also fades away dark spots and makes the skin clear and brighter. This will also provide protection from UV rays.

Application method for sensitive skin

How to use vitamin C serum is something that you should be well aware of when it comes to applying this. You can’t simply just apply it to the skin, knowing the right procedure is important. We provide a step by step approach on the application process to make you understand better.

washing face

Before applying the serum, you need to wash your face with warm water, clean cloth and some good quality cleanser ideal for sensitive skin. Make sure that you keep your skin moist.

Next, apply the vitamin C serum in the face and over the neck area if required with your fingertips. Some prefer to use cotton or brushes but it works best if used with just the fingers.

After that, gently massage the skin area and wait for around three to five minutes. Leave it there for the skin to dry for a while.

Finally, you apply the regular moisturizer and can repeat the process once a day or between alternate days.

How to Choose The Best Type of Vitamin C Serum

Ascorbic acid

With oxidized serum, it is better to avoid too much of ascorbic acid. Lowest possible concentration is better for sensitive skin. The safest choice would actually be to use it in the form of a cream. Skin care products use derivatives of ascorbic instead of natural acid. But in case of derivatives, the results will go slower. With natural ingredients, the result is faster. But for sensitive skin it’s better to avoid strong acid content.

Ascorbyl phosphate

Two important ascorbyl phosphate compounds include magnesium or sodium. For sensitive skin, you should opt for sodium ascorbyl phosphate. This is a water soluble derivative of vitamin C and is a useful content for providing skin care solutions. For those who have sensitive skin, you should use products that provide sodium ascorbyl phosphate other than ascorbin acid.

Ascorbyl palmitate

Palmitates are fat soluble derivative with vitamin C. This is a more stable form of the serum and it works better with sensitive skin. With sensitive skin, your skin can feel irritated at times by the use of ascorbic acid. Therefore, using this stable derivative is a better option for you.

Derivatives of ascorbic acid

Other than the two derivatives that we discussed about its better to avoid other new derivatives of ascorbic acid. Specifically if you are looking for instant results, new derivatives are not the right choice for you. For sensitive skin we would definitely recommend you avoiding new derivatives.

pH level

For sensitive skin, the pH level should be within 5.0 to 7.0. This should not impact your sensitive skin at all. With oily skin however, the pH level could be lower.


For the concentration, the percentage needs to be 5 to 10 percent of ascorbic acid in the product. With derivatives, the concentration can be 1 to 20 percent in the product. For sensitive skin, our recommendation would be option two. If you are still worried about does vitamin C serum really works with derivatives, you can rest assured that you get results.

Additional content

The idea of additional content is important when you need to know how to use vitamin C serum. Sometimes you can add those on your own to get the best results or you can simply find them in skincare products already available. Antioxidants can be a great additional content with your vitamin C serum. With the combination of vitamin C serum and antioxidants, you might want to re-evaluate your decision on how often the vitamin C serum should be used. It’s better to use the serum on alternate days if you plan on using it with additional content.


With regard to products, it is highly recommended that you avoid colored products and use white or off-white serums only. The chemicals in the colorful ones might adversely impact the sensitive skin.
