How does vitamin C serum work?

It is a challenge for the manufacturers to maintain vitamin C as we can lose it due to air, heat, and light.

Nature of vitamin C

Ascorbic acid is a natural form of vitamin C, and the skin absorbs it well, but it does not work well when mixed with some other solutions.

On the other hand, Ascorbyl palmitate shows more stability, when we combine it with other solutions. But the skin absorbs it less effectively.

That is why companies prepare it in the form of serums. And serums contain concentrations of vitamin C that are absorbed by the skin quickly.

Formation types

Mostly serums are water or oil-based products that the skin can absorb quickly.

Dermatologists recommend vitamin C serum after cleansing and before using moisturizers to get better results.


Sometimes, companies combine vitamin C serum with other antioxidants like vitamin E or ferulic acid to get more effective results. These combinations help reduce and reverse the signs of ageing.

A tip for the first time usage

Vitam C serum is very acidic sometimes and can cause skin irritation, so when you are using it for the first time, apply a thin layer and gradually increase it every other day.

A combination of vitamin C with retinol can cause skin irritation. You can alternate the usage timing if you want to use vitamin C and retinol serum. Use a retinol at night and vitamin C serum in the morning.

It will increase the effectiveness of vitamin C as a sun-protective. And will also reduce the retinol’s ability to increase sun sensitivity.

How to use a vitamin C serum

Vitamin C is generally used for all skin types and is considered safe, but some skin products can cause side effects.

Always do a patch test before using a skin product to check whether it causes an allergic reaction or not.

It is best to use vitamin C serum twice per day. For this

  • Cleanse your skin

  • Apply vitamin C serum

  • Then moisturize

Method to do a patch test

  • Select an area of skin like the forearm

  • Apply a small amount of product and wait for 24 hours

  • If no side effects occur, then you can use it. Otherwise, avoid using it in case of redness or rashes.

  • Follow all the instructions on the label for safe use.
