Cold Pressed Vitamin C Oil™


Rated 5.00 out of 5 based on 18 customer ratings
(18 customer reviews)

Our best selling Vitamin C Oil combines cold-pressed plant oils rich in “master antioxidants” with next generation (THD ascorbate) the gold-standard vitamin c ester  to rapidly correct dark spots, skin imperfections and to boost collagen production. This antioxidant formula instantly plumps and hydrates the skin for a radiant and glowing complexion. Can be used alone or mixed into your favorite serum or moisturizer.


There is a lot of buzz about the breakthrough ingredient Tetrahexyldecyl ascorbate – a lipid soluble form of vitamin C. Tetrahexyldecyl Ascorbate is able to penetrate the epidermis and move to the layer underneath called the dermis. Using tetrahexyldecyl ascorbate means your skin benefits more from the use of vitamin C products without the common irritation associated with L-Absorbic Acid.


Perfect For: All Skin Types – especially sun damage and aging skin types, devitalized complexions that need brightening and collagen boosting.


“This serum incorporates 10% tetrahexyldecyl ascorbate (THD), which is more lipid soluble than other forms of Vitamin C. (Translation: it penetrates the skin better and faster.)” – Forbes Magazine


“Mary makes the purest, most extraordinary oils for the face” – New York Magazine


    Tetrahexyldecyl Ascorbate 10% (Vitamin C Ester): 10% THD is equal to 18% L-Absorbic Acid - A superior and highly stable form of vitamin c ester, clinical studies have shown Tetrahexyldecyl Ascorbate to stimulate collagen production as well as clarifying and brightening the skin by inhibiting melanogenesis (the production of pigment) thereby promoting a more even skin tone. Unlike ascorbic acid, it will not exfoliate or irritate skin and will remain stable in formulations.

    I found out about this vitamin c oil from an article that I read so I decided to try it. OMG! I love this oil. It makes my skin so soft and smooth. It has a really beautiful light scent that smells like citrus, I love the ingredients and that I can wear it under make-up and moisturizers. This is my new favorite!

    I read an Article that mentioned this product so I decided to try it. This is so pure and powerful, I have already seen a change in my dark spots which have started to fade. I have been using it for 3 months now. This is so high quality and the aroma is light and uplifting!

    THIS IS MY NEW FAVORITE VITAMIN C SERUM! I read an article by Suze Orman who loves this oil so I decided to give it a try. After I did alot of research I realized this oil contains the very best form of vitamin c called: THD Absorbic – a next generation highly stable form of vitamin c that can boost collagen production. I was so tired of using L-Absorbic Acid which tends to dry my skin out and cause redness – not the case with this oil. It has faded my dark spots and leaves my skin so smooth. I use it Am and PM and also add a couple of drops after my foundation to give a little glow. I’m obsessed with the scent. Really high quality, will be purchasing again!

    I have been using this for about 3 months now and I have definitely noticed a reduction in my sun spots. I purchased this after searching out Tetrahexyldecyl Ascorbate and really love that is not only helps with my pigmentation issues it also gives a beautiful radiance to my skin. I use it in the AM and PM after cleansing and my essence. So beautiful, will repurchase!

    This is hands down the best vitamin c booster I have used. I have dry sensitive skin and had read about THD Absorbic so was looking for a product that contains this ingredient. I have a lot of sun damage so I have been using this to help with my dark spots. I apply directly to the sun spot and have already noticed a difference in the 8 weeks since I have been using this. The quality is so high and I love that it contains natural plant oils instead of silicones. So happy to come across this, a true find!

    This is my new favorite vitamin c treatment. I have been using this for about 3 months now and have seen a huge improvement in my dark spots and overall hydration in my skin. I have been a long time user of vitamin c serums and found most of them just dried out my skin. I love that this is an oil based serum and I have had no irritation at all from this. I love the light citrus scent, so uplifting and pleasant to use. BTW – I also use a few drops onto of my foundation to give a little extra glow.

    Seriously the best vitamin c serum I have come across so far. For years I have been on a quest to find the best L-Absorbic Acid on the market only to be disappointed over and over again with a vitamin c serum that does absolutely nothing for my skin. I read an article about (THD) Ascorbic and decided to try this after searching out the ingredient. I have now been using this oil for about 3 months and thrilled with my results. First off it does not dry out my skin or cause any irritation and I can already see my sun spots look a bit lighter. I have been using this day and night after cleansing. Will repurchase again. And by the way also want to mention how incredible the customer service is. I filled out the on-line questionnaire and received excellence advise back from the in-house esthetician. So helpful and knowledgeable.

    Love the results I’m getting with this vitamin c oil. I have been using this for about 4 months now and just reordered this. It is so gentle yet effective exactly what I was looking for! Highly recommend!

    I decided to purchase this after I did some searching for THD Ascorbate and so far very happy with the results that I’m getting. I have been using this at night for the past few months and starting to see my sun spots are getting a bit lighter. I really love that this in an oil form as my skin tends to be on the dry side. I will be re-purchaing my second bottle.

    Amy – Verified Buyer


    I have never had much success with vitamin c serums as most of them either leave my skin really dry and or irritated. I decided to try this one because I had read that THD Ascorbate was a more powerful yet gentle form of vitamin c. I have been using this for 8 weeks now and so happy to say that my dark spots are starting to fade and I have seen an increase in hydration. I use this at night after my cleanser, I don’t find I need a moisturizer but may add one overtop in the cooler months. I will be repurchasing this again!

    I’m really impressed with this vitamin c serum. I have oily congested skin and this is the first time i can use an oil on my skin without any breakouts. I love that this is the THD form of vitamin c and I also like the results I’m getting. This sinks into my skin with zero greasiness, such high quality ingredients that I noticed the first time I used this. Will repurchase again!

    This is such an amazing vitamin c oil and perfect for my dry skin. I love that I can combine a vitamin c plus beauty oil into one product! I have been using this day and night and so happy with how smooth and hydrated this makes my skin. I have noticed a slight reduction in my sun damage, will repurchase!

    I have tried so many vitamin c serums and none work as well as this one. I love that this is an oil so that I get both my vitamin c and beauty oil in one. My skin feels so soft and radiant after I use this, I never want to run out!

    THE BEST!!!!

    This is by far the best vitamin c treatment oil I have ever tried. I was searching for THD Absorbate when I came across this treatment oil. The ingredients are so pure and effective! It leaves my skin feeling so smooth and radiant and the light citrus scent is divine!

    Ava Daniels – Verified Buyer

    I’m on my second bottle of this vitamin c oil and never want to run out! It helps with my sun damaged and hydrates my skin better then any beauty oil I have tried. I love that this is a vitamin c and treatment oil in one and I don’t have to use L-absorbic acid which always left my skin dry and red. Such a great find! Very helpful and knowledgeable customer service, I highly recommend filling out the on-line questionnaire.

    I recently discovered Mary Allan skin care and filled out the on-line questionnaire (highly recommend) and her in-house esthetician emailed me back with a few suggestions including this vitamin c oil. I have sensitive / dry skin and have found L-absorbic acids too strong for my skin and now so thrilled that I can use a potent form of vitamin c that doesn’t cause irritation and actually hydrates my skin. I use this in the AM and PM, my skin feels so smooth and hydrated – will be repurchasing.

    So happy to come across this vitamin c oil at the SoHo beauty lounge. This has worked so well for me, better then any vitamin c oil I have tried. I use it in the AM under my make-up and just love how hydrated my skin looks.
