The Ordinary Ascorbyl Tetraisopalmitate Solution 20% in Vitamin F by The Ordinary


An oil solution for use for night and day, The Ordinary Ascorbyl Tetraisopalmitate Solution 20% in Vitamin F contains a high concentration of Vitamin C that acts as an effective antioxidant, brightening the skin tone and reducing signs of ageing. This serum is rich in Ascorbyl Tetraisopalmitate, an oil-soluble derivative of Vitamin C that can be used in higher concentrations without drawbacks.

It is one of the most stable derivatives of Vitamin C but, being a derivative, its potency will not be directly comparable to pure L-Ascorbic Acid.

It is provided in this oil-format formula in combination with Vitamin F, also known as essential fatty acids. Aside from the general benefits of pure Vitamin C, Ascorbyl Tetraisopalmiate has been shown to offer specific skin brightening benefits. The Ordinary Ascorbyl Tetraisopalmitate Solution 20% in Vitamin F is ideal for dry skin-types, mature skin, or those who are showing signs of premature ageing through sun damage.

Good vitamin C - 11-01-2019 by

This product is easy to put on and feels great on my face. It has definitely dulled down the red tones in my skin.

Great Vitamin C - 09-01-2019 by

This is a nice thin oil that is absorbed quickly and skin looks instantly brighter.
I prefer this consistency to their other vitamin C options too.

Skin is clearer - 31-12-2018 by

I'm in my fifties with good skin. This product has made my skin slightly more clear and bright. No reaction. I may try the stronger vitamin c next time.

Great! - 15-12-2018 by

It really works well! The oil is super thin and non greasy and is really nice for my dry skin! Helps my hyperpigmentation especially because I can use it night and day.

Lacklustre - 10-12-2018 by

Initially I thought this was AMAZING, but then I went a few days without using it, and my skin seems to have deteriorated even further. It feels more rough and damaged than before I had begun using the product.

So I reapplied myself to the regimen, and again, skin felt amazing when I was using it daily, but as soon as I stopped (late nights out/holidays), then my skin seems to not retain any of the benefits of this product whatsoever, and actually feels worse than before I had started.

Will not be buying this product again.

Too early for results but I do like it - 28-11-2018 by

This product was recommended to me in Chat on the Adore Beauty site as I was looking for anti-ageing products and had heard about The Ordinary. I have used this product for just over a week so far and although it's too soon to really see results, I do like how it feels. It's a really light oil infused with the ascorbyl additive and it feels luxurious going on. You don't need much so use sparingly. I look forward to seeing how my skin looks as time goes on.

Ordinary - 12-11-2018 by

This product I used in addition to other The Ordinary products to help brighten my skin. I am unsure how much of a difference I saw however it is quite gentle for people who have sensative skin. I personally prefer something more stronger such as the VItamin 23% as I felt like this really worked well. This however is very strong so it maybe good to start off with something like this product first.

A great product - 30-10-2018 by

I tried this product as the VITAMIN C SUSPENSION 23% + HA SPHERES 2% did not work for me. I absolutely love it! It aborbs quickly and leave my skin feeling soft. And it works well under other face creams and suncreens. Will definitely re-purchase.

Great - 26-10-2018 by

I use this as a serum before my moisturizer in the mornings.... early days yet

Just repurchased - 24-10-2018 by

This was the first higher potency vitamin C serum I've tried and I was pleasantly surprised to notice a difference! I cannot compare it to using pure l L-Ascorbic but I have dry skin so I've just repurchased this along with the powder to try because I just love the way it doesn't dry my skin out at all. If you have dry, sensitive skin I would recommend.

Best ! - 22-10-2018 by

Love this so much ! The feel on my skin is great and absorbs so quickly

LOVE this product - 18-10-2018 by

It takes a while to notice a difference for brightening products but now, a month later after using this product every night, I can really see a change in my skin. I have combo skin with issues with redness and my skin has become so much more even after using this product, a little goes a long way too. I like the 'dry oil' kind of consistency and wear it underneath my serum before bed. Definitely will be ordering more!

Good for dry skin - 10-10-2018 by

This very light texture helped keep my skin moisturized during cooler weather and the Vitamin C really lightened! No side effects and my acne scars started fading after 2-3 weeks. This light jojoba oil-based Vitamin C also has tomato extract which is an excellent antioxidant against sun exposure!

Yes! - 24-09-2018 by

I would recommend! Skin looks brighter. Texture is little bit oily.

Skin looks brighter - 17-09-2018 by

I have only been using this roughly 2 weeks, before my moisturizer at night.
my skin looks brighter.

I have very clear skin anyway, however get spots on my chin.

I haven't had a spot while using this product, which i usually would when using a new product.

I will definitely be slowly moving my beauty routine over, i have just purchased the caffeine serum.

Improved skin tone - 05-09-2018 by

I have started using this with a few other the ordinary products a couple of months ago. My skin seems more even toned and clear now. So I will keep using. One bottle goes a long way too!

A bit too runny... - 27-08-2018 by

I have dry skin and want to get rid of my sun spots and blemish scars. I use 2 other The Ordinary products before this one: Buffet and Niacinamide + Zinc. I find that the ATS pills after using these products and the consistency is just like water so it is very hard to get it even around my face. I try to get it mostly on my sun spots and just pat it in with my fingers, not rubbing around as this will make it pill. It leaves your face looking oily so I recommend using a setting powder after. Overall, I can't see any visual differences but will persist as I know scars take a long time to fade.

not the best vitamin C the Ordinary has to offer - 24-08-2018 by

I've tried quite a few different vitamin C brands and products and found that this was my least favourite! I found the oil interacted with other skincare I had on my face and created a weird texture. I also hated the smell. However I did purchase this as it's one of the more stable and therefore effective formulas of vitamin C. It does work however I would not be buying it again.

Works! - 16-08-2018 by

Skin definitely seems brighter. Texture is great! No reaction with my sensitive skin and a little goes a long way!

Love this Vit C oil - noticeably brightens and feels wonderful on skin - 14-08-2018 by

To be honest I was a bit reluctant to try this product as I already use about 6 skin care products and was trying to simplify my routine. But I couldn't resist giving this a try as I had been using TheOrdinary's Arbutin for hyperpigmentation and wanted to give my 40+ skin a bit of a boost. It's only been a few weeks but already my skin looks clearer, brighter and more even toned, better than I expected. The oil is very light and a little goes a long way. This would probably rank as one of favorite TheOrdinary products because it's so effective and feels so nice on my skin. If you're older and looking for that little bit extra moisturizing and brightening, I highly recommend this.

Very good hydrating and brightening product - 13-08-2018 by

This has been great as a combination hydrating and brightening product. The ascorbyl solution is really gentle. I haven't notice dramatic brightening since using it, but I do think it is gradually contributing to more even skin tone.

Great Product for Price! - 13-08-2018 by

I purchased this to see how it went as I am a big believer in vitamin c in your skin care routine. It is a light oil and easy to apply, I apply it at night before my moisturiser and can certainly see the difference again after not using something similar for a month. I think it a great product for the price and works well, especially considering the vitamin c I previously used but still prefer is close to $200. But The Ordinary does offer other vitamin c products so you may have to play around with them depending on your skin type. I have sensitive skin.

Not for me - 01-08-2018 by

I am a fan of the Retinol 1% bottle from The Ordinary and decided to try out this vitamin C product as it is a price catch. However, I don't think this product works for me. When I applied this oil on my face, it seems like it also rubbed off former skin care products (my skin care routine is cleansing gel, lotion, water-based serum and this oil) and it's worse in the morning when I applied sunscreen after this oil, it came out like dead skin all over my face. I'm still using the first bottle and have not seen anything better yet. I'm going back to Skinceuticals Vitamin CE Ferulic after finishing this bottle.

Love it!! - 24-07-2018 by

I added this product into my the ordinary routine to give my skin a boost and this surely did. I use it over the top of buffet and I am loving the result. This is a quarter of the price of the last vitamin c serum I was using and I would prefer the results this one has given me. Another product in the range that gives fantastic results for a fraction of the price compared to other active skincare ranges. This range is seriously addictive.

What a great item - 24-07-2018 by

Silken feel and absorbs really quickly. Have only been using for a week and while I haven't noticed any anti-ageing effects, it is certainly a welcome addition to my slightly dry skin care routine. Will continue to use for sure.

Really light dry oil - 20-07-2018 by

This is a really light dry oil that spreads really well and absorbs nicely intense your skin. I use it in rotation with other serums and I would say there’s been a noticeable difference in my skin since using it.

Awesome - 20-07-2018 by

This product is amazing due to the fact it is so cheap and works exactly the same (if not even better) then other Vitamin C products that I have used that are 3 times the price.
I use it in the Morning either on its own or mix into my moisturiser to keep my skin fresh and bright and its also helped with acne scarring.
Love all the Ordinary products.

Excellent serum - 18-07-2018 by

I had originally used the "ascorbyl glucoside" vitamin C by the Ordinary, but found that that balled up my makeup/ any other skincare I put over it, so I mainly used it at night.
I prefer the texture of this by a mile. It's such a light oil (which is not "oily"), sinks in so quickly. My only complaint is the slight smell which doesn't linger at all.
I noticed brighter and more even complexion as soon as the next day.
I can't wait to keep using it, and have bought it for a friend who loves it too.
Such a great formulation of vitamin C, highly recommend!

SO. GOOD. - 05-07-2018 by

I have never, seriously never, used a product that has made such a huge difference to my skin. I've always been willing to spend money on good skincare because I have pale, sensitive English skin, and I know I'm going to age badly if I don't actively care for my skin. I'm 45 and this product has dropped years off my skin in under two weeks. I use it morning and it has taken the place of Estee Lauder's Advanced Night Repair at night -- and it is completely out-performing it. The light oil-like texture is beautiful to apply and excellent if your skin is on the dry side. I'm using The Ordinary's Natural Moisturising Factor over the top, and the results are astounding. My skin is brighter, softer, firmer and a couple of pigmentation spots are already fading. This is not my first use of vitamin C but it's by far the best I've tried. And the price is so insanely reasonable, there's nothing to do but love this product. Five big gold stars.

Great Vitamin C - 25-06-2018 by

I purchased this product so that I would incorporate a vitamin C into my skincare regime and this product did not disappoint! I use it before T.O. rosehip oil and find my skin to be super soft, smooth and makes my skin it!

Instant results - 21-06-2018 by

Love love love this vitamin c formula. I use it at night and the first morning after use my skin looked so much brighter and my acne scars looked lighter too! It'll will need continued use to get more benefits, however it's a favourite of mine. It does smell a little weird, but that goes away after a minute or two so I don't mind. Love the pricing of this, as I could get about 5 bottles of this compared to my drunk elephant one!

Amazing & affordable Vit C - 13-06-2018 by

Love this product! After spending months (and significant amounts of $$) purchasing Aspect Vitamin C I eventually swapped to this product to help with my acne scarring.

I use it in the evenings around my chin & cheek around (plus some under the eyes as it's supposed to help w. plumping); can't say much for my under eyes BUT the skin around my cheeks and chin is mostly free of scars.

This is the BEST product I have found for scarring to date - would highly recommend.

A little goes a long way - 13-06-2018 by

Loving this product. I have relatively normal skin and from day one using this product my skin looked brighter. A little bit goes a long way with this one, I use it at night onto of my other products inplace of a night cream. The smell doesn’t bother me as it’s clearly not fragranced

Amazing product! - 11-06-2018 by

I have used this product for 2 months regularly now, mostly before I go to bed and sometimes in the mornings as well if I feel like it ( happens more regularly now that its getting colder ) In the first couple weeks I have not noticed much in my skins appearance but then all of the sudden my skin texture got so much better, my skin is much more even and I don't have to worry about my skin not being moisturised. It is very watery, but it spreads much more evenly and a little goes a long way.
I will definitely repurchase this as soon as I run out :)

Undecided. - 08-06-2018 by

It seems to absorb well. The smell is okay and I like the texture (thin and spreads evenly). The downside is that I don't notice much of a difference in my skin. Vitamin C products seem to take a long time to show their benefits though, so I will keep using this.

Works for me - 18-05-2018 by

I can see this product won't work for everyone it's quite runny but it works for me I use it daily in the morning, it dries quickly and light enough to layer with makeup. I feel it's improved my skin texture

Not sure about this - 05-04-2018 by

I have combination oily skin and this is a oil. My skin usually likes oils but this one sits on top of my skin. I haven’t noticed any effects from using it either. Not a huge fan of the smell either. I love lots of other products from this line but it’s a no for me on this one

Fabulous serum - 19-02-2018 by

I love this serum, it is a little oily however I find this texture fine. As with all Ordinary products - the price is fantastic for serums that really work.

No more $$$$$$ serums for me including Sisley which set me back hundreds.

Good serum if you can handle the texture - 31-01-2018 by

I have combination skin, and love oils and vitamin c, so thought that I would love this product; however, I found the texture and smell off-putting. This product is a thin oil, which never properly absorbed into my skin, causing issues when I tried to layer products on top of it. Despite its flaws, this product does have great brightening benefits.

Like a dry oil - 19-12-2017 by

I love this. Well, I hate the smell. But i love the texture and effect. Helping with my post-ance hyperpigmentation, and helps my skin glow. I use in the morning with marula oil, the natural moisturizing factor and my spf.
Don't be afraid of using oils if you are oily. One of the biggest improvements to my skin has been using oils and oil-based products, including two to five oil skins everyday, and an oil cleanser. Properly moisturising my skin with oils has helped reduce my oiliness.

Skin brightening and very hydrating! - 14-12-2017 by

As someone under 25 with sensitive/oily/dehydrated/acne-prone skin, I was skeptical of whether this would be effective or disastrous considering this product is oil-based. To my delight it has done wonders for my face and has helped brighten and hydrate my skin without leaving me an oily mess, in fact I think I'm less oily now than before I incorporated this in to my skincare routine. I use it both day and night after washing my face and I think with continued use the quality of my skin will only improve.

My first Holy Grail product! - 22-11-2017 by

This is the very first review I've every been motivated to write about any skincare product.
I have used many Vitamin C formulations in the past - from Skinstituit, Medik8 & Ultraceuticals to name a few.
This is the first time my skin has responded so well - it is softer, firmer and pigmentation is gradually lightening. I'm extremely surprised and pleased that such an inexpensive product works so well.

It is an oil which surprised me, but it doesn't leave any oily residue and is great under makeup, even in 30 degree days.
I'm definitely a fan of The Ordinary!

Oils are oily - 16-11-2017 by

In my quest to try one of the Vitamin C serums from The Ordinary, it seems I bought the wrong one. Easy to get Ascorby Tetraisopalmitate confused with Ascorbyl Glucoside, right? I have oily skin so this oil-based product didn't work wonders at all. I'm now using it on my hands and arms before bed in a desperate attempt to defy ageing in other parts of my body. Those parts seem happy. No oily residue. Waste not, want not.

Hidden gem! - 02-10-2017 by

I think this is the underdog of the ordinary skin line.
I much prefer it over the other vitamin c product as it's less irritating to the skin.
Brightening and hydrating :)

One a week after applying the Buffet works a treat for over 50 skin - 03-09-2017 by

The Ordinary is far from it. This is a must have

Love it! - 20-07-2017 by

This product makes my skin glow! It's made a huge difference in my skin and will definitely repurchase.
