I have used a lot of vitamin C serums from different brands, just to put them to the test, to see for sure how they react on my skin, while I give a well tailored and honest review about my experience with them.

Timeless, SkinCeuticles, Geek & Gorgeous C-Glow, and Cerave Skin Renewing vitamin C  serum has been one of my most loved brands of L-ascorbic acid-based vitamin C serums. 

While The Ordinary Ascorbyl Glucoside SerumThe Ordinary Ethylated Ascorbic Acid Serum and FaceTheory Regena C20 Serum has been one of my best serums when it comes to vitamin C derivatives. And this time, I have decided to give my honest review on an oil-soluble vitamin C derivative which I have been using every day for four (4) weeks — The Ordinary Ascorbyl Tetraisopalmitate — a 20% vitamin C derivative solution in Vitamin F.

For the sake of this content and to provide a precise and honest review, I used this oil-soluble vitamin C serum diligently for four (4) weeks, both morning (AM) and night (PM). 

So if you’ve been longing to use this serum but want to read an authentic review about it before plunging ahead to purchase, then you’re on the right page. 

Oops, this is where the confusion sets in about The Ordinary Ascorbyl Tetraisopalmitate Vitamin C Serum.

The product title says “Ascorbyl Tetraisopalmitate“, while on the ingredients list, it says “Tetrahexyldecyl Ascorbate“. 

I mailed Deciem (The Ordinary), asking them for clarification to clear the confusion regarding their Ascorbyl Tetraisopalmitate Vitamin C Serum, and below was their response: 

Ascorbyl Tetraisopalmitate and Tetrahexyldecyl Ascorbate refer to the same ingredient. Tetrahexyldecyl Ascorbate is the INCI name our supplier has chosen to identify their material by

This got me more bemused, because after a thorough research, I came to discover that although both Ascorbyl Tetraisopalmitate and Tetrahexyldecyl Ascorbate shares the same similarities in several ways, but their molecular structures differ, (They have the same number of elements. but are arranged differently).

But because Tetrahexyldecyl Ascorbate was listed on the ingredients list, I assume that’s the ingredient contained in this product.

What Is Tetrahexyldecyl Ascorbate?

To cut it short and sweet, tetrahexyldecyl ascorbate is a very stable and oil-soluble derivative of vitamin C. By oil-soluble, it means, it can dissolve in oil and also be used or found in oil-based skincare formulations. 

According to research study, tetrahexyldecyl ascorbate penetrate deeper into the skin dermis than other forms of vitamin C derivatives, due to its oil-soluble nature which gives it a good delivery system to penetrate the skin.

Oil penetrates the skin better than water. Therefore, oil-based skincare products tend to penetrate the skin better. That also implies that anything water-based needs oil for better penetration. 

This form of vitamin C isn’t acidic in nature and therefore won’t cause any sort of exfoliation (like L-ascorbic acid does) and won’t cause skin sensitization or irritation. That’s why it’s recommended for people with sensitive skin who can’t deal with the L-ascorbic acid form of vitamin C.

Also contains jojoba seed oil and squalane for increased skin hydration. 

The prominent ingredients used in this formulation will be briefly explained below:

  • Tetrahexyldecyl Ascorbate: A stable and oil-soluble form of vitamin C, which penetrates deep into the skin (more than other forms of vitamin C) to establish its skin benefits by fending-off external aggressors, diminish skin aging-signs and Improve skin appearance. It can be used in a high percentage without drawbacks and won’t cause increased skin sensitivity or irritation unlike the L-ascorbic acid form of vitamin C. 
  • Vitamin F: A skin conditioning vitamin and fat which helps soothe skin irritation and inflammation such as dermatitis and psoriasis as well as regulate healthy cell function. In skincare, vitamin F is used to represent linoleic acid, an essential fatty acid that is rich in omega-6. Fats are also known as lipids, and they’re incredibly important when it comes to maintaining a strong, healthy stratum corneum (the protective outer layer of the skin).
  • Jojoba Seed Oil: Jojoba oil is a humectant ingredient. This means that it works to seal your skin with a protective barrier to keep it from losing moisture, thereby increasing hydration and moisture retention [1].
  • Squalane Oil:  Squalane is a plant derived or hydrogenated oil which is used in its pure form or in cosmetic formulations for moisturizing, hydrating and soothing the skin.

Possible Questions & Answers

Q: How did you use The Ordinary Ascorbyl Tetraisopalmitate?

A: I apply the serum after cleansing and hydrating, before my moisturizer. I simply apply 2-3 drops on my face (a little goes a long way), gently massage till fully absorbed before sealing in with my moisturizer. 

On the days I apply it with tretinoin, I apply the serum first, after cleansing and hydrating, before applying a pea-size amount of tretinoin, then follow up with my moisturizer.  

Q: Can people with oily skin use The Ordinary Ascorbyl Tetraisopalmitate?

A: Though this is oil based, I think this will work for a variety of skin types. It will add extra hydration for dry skin types and if you are oily, it helps to replenish your skin without greasiness. But if you’re concerned it may aggravate your oily and acne-prone skin, you can use other vitamin C derivatives from The Ordinary brand, I recommend The Ordinary Ascorbyl Glucoside

Q: Can this serum be applied morning and night?

A: Yes. The Ordinary Ascorbyl Tetraisopalmitate vitamin C serum can be applied both morning and night. Vitamin C helps protect the skin against free radicals (while you explore your outdoor activities) and also helps strengthen the barrier protection of your sunscreen (during the day). While it delivers antioxidant and skin repair potentials to your skin at night while you sleep.

Q: Why can’t I use tretinoin everyday and also during the day?

A: Using tretinoin everyday increases chances of incurring inflammatory irritation, while using during the day increases skin’s sensitivity to the sun which can be deleterious if sun protection measures aren’t taken. Therefore, it’s best advised to use tretinoin every-other-day (to give skin time to get used to it) and limit use at night time only.
