Finding the Perfect Vitamin C Product

Finding the Perfect Vitamin C Product

Which Vitamin C serum is right for me?

Ask any physician or skincare expert what your skincare routine should include, and you will hear many different opinions. All or most of which will include some sort of Vitamin C product.  Why is that?  The benefits of a well formulated Vitamin C product are immense. These range from correcting your skin by firming, lightening, and brightening to preventing future damage by neutralizing free radicals.

Vitamin C comes in many different forms. There are extensive (and complicated) debates over which form of topical Vitamin C can best penetrate the skin and therefore reap the best benefits. The two top forms used in medical grade products are L-Ascorbic Acid and Tetrahexyldecyl Ascorbate. Which is better? Well that depends on who you ask. Every company will say their Vitamin C ingredient is superior. As for the scientific evidence, the jury is still out. Here is a concise version of the debate between the two. 

L- Ascorbic Acid is Vitamin C in its purest form. All other forms are derivatives and must convert to L-Ascorbic Acid after entering your skin. But L- Ascorbic Acid has some problems. Mainly it is incredibly hard to stabilize and is only able to penetrate your skin at a pH lower than 3.5. Since your skin’s natural pH is 5.5, the low pH of stable L-Ascorbic Acid can cause some irritation. All products containing L- Ascorbic Acid are not equal, and you need to be wary when choosing an L-AA product.

Tetrahexyldecyl Ascorbate (THDA) is a oil-soluble derivative of Vitamin C. With a neutral pH of 7, this product is less irritating and much more stable than L- Ascorbic Acid. Although the fat solubility of this ingredient can make it easier to penetrate the skin, the debate lies in how much is actually converted to L- Ascorbic Acid once it enters the dermis. Lastly, THDA is a much more expensive ingredient than L-Ascobic Acid, therefore products containing Tetrahexyldecyl Ascorbate are typically pricey as well.

So which form should you choose? Choose a reputable medical grade Vitamin C product that is right for your skin type. Both of these ingredients have benefits, and you want to choose one best suited for your specific skin type. Medical grade products are backed by clinical trials or data proving their efficacy. Considering Vitamin C products can be pricey and useless if unstable, you only want to use one that has been scientifically backed and proven to be effective.

    What do you think of the product Isdin Flavo-C by Isdinceutics?

    It’s substantially cheaper than others so am wondering if you have any experience with it.

    Thanks,
    Linda

    Hi Sarah,

    I’m glad that you received your skinbetter Alto. Please let us know your thoughts on the product. It is by far one of our favorites!

    I will actually write another article on Vitamin E so I can give you a deeper understanding. But in short Vitamin E is typically thought to clog pores and be a greasy and “oily” oil. For this reason it is not recommended for patients with extremely oily skin or some patient who are prone to breakouts. Look for a up and coming blog post that will take a dive deeper into this questions. Any any topics you would like to hear us talk about please let us know! We would love to hear what you want to read/know about.

    Thanks,
    Courtney Broder

    Loved this article and looking forward to starting my Skinbetter Alto defence.

    Really interested to understand why vitamin E needs to be avoided on blemish prone skin if you could kindly provide an explanation that would be great.

    Many thanks,

    Sarah
