Vitamin C Serum: What is it and Why Should I Use It?

There are so many different serums on the market today that it’s hard to know which to buy. They all promise to be the best at anti-aging, or reduce breakouts- but do they really? When it comes to serums, it’s crucial to look at the ingredients. With Kristyl Skincare, I offer several powerful serums made of high quality ingredients. While I am passionate about each of them, I have a confession to make - the Vitamin C serums are by far my favorite! Vitamin C is such a powerful vitamin that can do everything from increase collagen to fade dark spots. Here is a bit more information on why a Vitamin C serum is a must in your skincare routine:

Vitamin C Serum Benefits

  • Anti-inflammatory - especially acne prone skin

  • Anti-aging - reduces oxidative stress and regulates melanin production to effectively reduce both wrinkles and age spots.

  • Increase collagen - plumps and smooths the skin

  • Increase hydration

  • Protects skin from free radicals

What is Vitamin C?

Vitamin C, in its purest form, is known as ascorbic acid and is an antioxidant naturally found in the skin’s epidermis. Vitamin C can be applied topically to the skin and has amazing results! There are different types of Vitamin C found in skincare products, which all have slightly different effects. For example, some forms of Vitamin C are better at brightening skin, while others forms are better at reducing inflammation.

Be Aware!

Not all forms of Vitamin C are created equal so make sure to read your labels! Always look for ‘Active Ingredients’ on your serums and look for the percentage used. If you do not see a percentage amount, this usually means the active ingredient is below 1%.
The three most common forms of Vitamin C are;

  1. The most potent form of Vitamin C with the best results is Ascorbic Acid but make sure your serum with ascorbic acid has NO water present! As this makes ascorbic acid unstable.

  2. The best Vitamin C for brightening the skin and fading sun spots is Tetrahexyldecyl Ascorbate (THDA).

  3. The most common form of Vitamin C used in most serums, suncreens and moisturizers (also the cheapest form of vitamin C) is Sodium Ascorbyl Phosphate which usually comes in a high percentage because its not as potent and therefore needs more to have a result. Serums with this ingredient are usually cheaper in cost.

Our bodies only absorb between 10% - 15% of ascorbic acid at any one time. So choosing a higher percentage doesn’t always make your Vitamin C Serum better.
