The Ordinary Ascorbyl Glucoside Solution 12%  by The Ordinary


Vitamin C is an effective antioxidant, brightens the skin tone and reduces signs of ageing. In its pure form, Vitamin C is unstable in water. Ascorbyl Glucoside is a water-soluble derivative of Vitamin C. It is much more stable in water but it is less potent than direct L-Ascorbic Acid.

Being more compatible with water allows for a very pleasant serum texture. The Ordinary Ascorbyl Glucoside Solution 12% is considered a gold standard of Vitamin C derivatives due to its high stability and comfortable use, but it's impossible to achieve extremely high L-Ascorbic Acid potency with this solution.

Aside from the general benefits of pure Vitamin C, The Ordinary Ascorbyl Glucoside Solution 12% offers specific skin brightening benefits, leaving the skin tone more even and unified.

Gentle and brigthening - 12-11-2018 by

I was a bit worried about starting to use this, as my combination skin is quite sensitive/reactive and I've heard vitamin C can be somewhat active, but I've had no reaction to it whatsoever. I apply this in the mornings usually (but alternate with The Ordinary Niacinamide) as the first step after cleansing and then apply my other more heavier products like moisturiser, sunscreen etc. It's great for in the morning as it helps protect your skin from free radicals too.

High strength - 12-11-2018 by

Evens out skin and brightens. I like the high strength of vitamin c.

No adverse effects - 05-11-2018 by

My skin (oily, no pigmentation issues) has reacted just fine to this Vitamin C serum, however I've found it can ball a little under oily products like my bb cream.

Great Texture - 29-10-2018 by

I switched over to this from the vit c suspension cream from the ordinary – love the texture and how quickly it absorbs, leaving my skin feeling super fresh after. I have oily sensitive skin and it has not caused any irritation whatsoever!

not for complicated skin - 22-10-2018 by

I have being using a different brand for over 12 months and thought i would try this one for a change. I found it really harsh and sticky on my skin and woke up with welts and sore pimples all over my face. I persevered and kept using for a week to see if my skin was just adjusting, but make it worse everyday. Be careful if you have sensitive/complicated skin. Love this brand but not this product

It’s ok - 22-10-2018 by

I wanted to try the serum for a vitamin c fix rather than the powder so I gave this one a go. It’s non irritating however haven’t really noticed any changes to my skin. I also have troubles when applying in the morning as it doesn’t sit under my makeup well so now only use at night. Very cost effective , no major complaints but will probably go back to powder

Part of my daily routine. - 19-10-2018 by

I have used so many vitamin c serums in the past, this is by far my favourite. It is high strength so you know it's doing the best job to combat free radicals in the skin.
This variant doesn't irritate my skin like L-Ascorbic Acid, and I've definitely seen better results with this than with any other vitamin C.

Before this product I used the Mesoestetic Energy C Complex, which is a 10% L-Ascorbic Acid, which felt really nice, smelt really nice, but oxidised quickly and upset my skin. This is a 12%, and doesnt irritate. My skin is definitely brighter thanks to this vitamin C.

Perfect skin fixer - 11-10-2018 by

This is the third bottle of Ascorbyl Glucoside Solution I have purchased, I added it into my routine about 8 months ago, using it daily, and have seen great results. I bought this because I was concerned about my skin texture, signs of ageing and reducing my redness. This product has really helped my skin glow and although 8 months probably isn't enough to know if it's stopped me ageing, I feel firmer and look fresher. I use this along with the Niacinamide + Zinc from The Ordinary, and I feel that together they fight all my skin problems. I am confident in my skin for the first time.
I have very sensitive, allergy prone skin and haven't had a reaction to this product at all, in fact it has a very soothing feeling to it.
The only downside to this is it can feel a little tacky and you definitely have to wait close to 15 minutes for it to absorb before applying makeup or moisturiser over it.

Good - 10-10-2018 by

Seriously, this has done wonders for my skin. In just 1 week it faded my hyperpigmentation from previous breakouts and evened out my skin amazingly. 3 weeks later I don't even wear foundation out just a little cover up and I'm good to go. It has brightened and evened my skin with no reaction or flakeyness.

See I've definitely seen a difference - 01-10-2018 by

My skin is brighter, clearer1. I do mix this with the recommended product that the ordinary has and my moisturiser I love it

Light and Brightening! - 27-09-2018 by

With dry and sensitive I’ve been slowly introducing The Ordinary Serums into my skincare routine, and this is the fourth; AM & PM. Definitely lighter, more clarified skin.

not for everyone - 26-09-2018 by

Skin: combination.

I used to have mad hippie Vit C serum which i absolutely loved. However, decided to try something new as this brand on hype at the moment. I pulled off other serums (acids, retinol) to see if there is effect of this particular product within 4 days, used it pm only followed by the night cream.
I got the opposite effect from brightness and even skintone. A few nearly healed red spots from breakouts got inflamed and my glowing smooth skin became dry and flaky., and i got more blackheads on the nose. i also found cream was absorbing very quickly (as never before) as if i am extremely dehydrated. Even after reach bobby brown cream, i had to apply second layer to look nice and glowy.

Yes, i used to react with dryness to my retinol serum (Aspect) (for instance)as a part of build up process but despite it, it also cleared up the face, tone and smoothed wrinkles. after which it started hydrating the skin, i even use several pumps now.

Will come back to Mad Hippie for the summer, and introduce my skin to aspect C formula during the cooler season for the stronger clinical formula. As for ordinary, the whole brand seems to have low grade concentrate/low quality, purple peel also very average and works worse than other acid products (although those i've tried were 3-4 times more expensive).

as the result, i need to have a restorative measures to bring back smooth structure and moisture to my face.

No hate here, just an opinion from the experience i had with 2 products from this brand.

Great for acne redness and scarring! - 25-09-2018 by

I have combination to oily skin and often experience breakouts on my forehead. I have been using this after I apply my moisturiser with just 2 drops on each cheek. Over the past few days I have noticed the redness and scarring from acne on my forehead has definitely improved! My overall complexion is alot brighter and even, and will be purchasing another bottle when I run out!

Works great - 25-09-2018 by

I was previously using the Paula's Choice Vit C serum, and have since switched to this due to cost and convenience. The first 1-2 months of using Vit C did most of the lightening, so now the freckle fading process ifs slower. The Ordinary solution does a great job and I use this most nights with good results. Will continue to purchase.

Instant glow - 21-09-2018 by

Dullness has never really been something i worried about, but after seeing the results of this serum, i won't be going back!

nice consistency - 17-09-2018 by

I really like the consistency of this product. It makes it easy to apply and soaks in nicely. However, after trying out other vit c products I feel like this actually doesnt do much for my skin compared to other brands.

Flawless application, perfect results!! - 17-09-2018 by

I have fair olive skin in winter and range from dry to combination skin. Honestly, this is PERFECT for me! My routine consists of alternating between morning and night with the The Ordinary’s Niacinamide + Zinc solution and moisturize each time after. I had intense break-outs and scars (I picked a pimple... or two) and within DAYS the majority of scarring cleared and left skin feeling supple again! Not turning to any other skin-care range, how could I?! Recommend that you pair with the said other product above alternating and make sure you exfoliate twice a week (no more), it’s worked for me!!

Great texture! - 12-09-2018 by

I have dry, sensitive skin and concerned with some hyperpigmentation on my cheeks. The serum absorbs well on my face. I mostly use it in the mornings. My complexion is evened out and the serum layers well with my BHA lotion and sunscreen lotion. However, I don't quite like the slight chemical scent but it goes away rather quickly once absorbed by the skin.

Overall, I do like the product!

Beautiful Serum - 10-09-2018 by

This serum is just beautiful. It doesn’t irritate my skin what so ever and I have sensitive/acne prone skin. I find it to be hydrating, brightening and smoothing. It is a little tacky, so I find it best to apply a moisturiser over the top or another serum that isn’t tacky.

Fav The Ordinary Vit C product - 06-09-2018 by

I have tried the vitamin c powder and vit c cream from the ordinary as well. This product is by far the most convenient, easy to use product. I normally use 3 dropped in the morning followed with niacinamide in the evening routine. This product helps keep my skin bright and clear.

Gentle vitamin c serum with results - 22-08-2018 by

I have dry and a little bit sensitive skin. This is a beautiful serum and it works well mixed with niacinimide. Using these two together I definitely noticed a brighter skin tone. There was zero irritation for me and it was lovely to use. I’ve since moved up to the Vitamin C 30% but I think the Ascorbyl Glucoside is the ideal first vitamin C to use before moving on to the pure L-Ascorbic acid serums.

Wouldn't use if skin is breaking out - 21-08-2018 by

I had been looking for a vitamin c serum. I purchased this as a review said it was similar to the drunk elephant serum which it is. Unfortunately at the moment my skin is breaking out due to stress and it aggravated my break outs the first time I used it. I'm just waiting for my skin to clear up to use the product again. I would recommend this to anyone seeking a vitamin c serum. The product has a good consistency and is a good price.

this works! - 16-08-2018 by

my skin is brighter and more even

Good reliable vitamin C - 07-08-2018 by

I've found this to be a good vitamin C hit - i've had similar results to Drunk Elephant's vitamin C serum which is much more expensive.

Good - 09-07-2018 by

My understanding of this product is that it, when applied, your skin converts it to Vit C. It is a mild, but effective product. I use 3 drops after Niacinamide am & pm. I find this combo evens skin tone & lightens red marks left by acne. It has not been in stock for months, so am forced to purchase elsewhere. My skin is acne prone/ mature/ oily/ dehydrated. This is the only vit c from The Ordinary, that I can use - the others are too strong or cause breakouts. It would be great if The Ordinary offered just a simple VitC + ferulic serum - I find the range unnecessarily complicated. My second choice would be Ascorbyl Tetraisopalmitate Solution 20% in Vitamin F, in terms if ease & effectiveness, but I find the jojoba oil breaks me out. I will continue to purchase Ascorbyl Glucoside for the benefits it provides my skin & affordability.

Absorbs quickly with no residue - 02-07-2018 by

Love this bit c. I use it every morning before the reservatrol and ferulic combo, and it supports the good work my apt does. Absorbs quickly, too :)

Love this vit c. I use it every morning before the reservatrol and ferulic combo, and it supports the good work my spf does. Absorbs quickly, too :)

10/10 - 27-05-2018 by

Amazing product! Leaves my skin feeling and looking radiant. For me this one is a must have.

Really good - 18-05-2018 by

This was the first Vitamin C serum I'd ever used, and I had no issues or side effects at all when using it over a couple of months. I then though I'd "graduate" to The Ordinary's Vitamin C Suspension 23% + HA Spheres 2%, which gave me a bizarre breakout on my very first use! Consequently, I have come back to the Ascorbyl Glucoside Solution 12% and am very happy with it. No burning, no itching, no blemishes. It is totally gentle and unnoticeable upon application, yet gives a lovely brightening effect to the skin.

Nice and comfortable - 16-05-2018 by

This product is very nice to apply and sits comfortably on the skin, I like to use this as my last step in my skincare routine a few days a week. This looks beautiful and glowing when applied, however it does not sit well under makeup for me as it pills so I wear this on my makeup free days.

LOVE LOVE LOVE!!! - 14-05-2018 by

I've tried most of the Vitamin C derivatives in the Ordinary's range, and this is my FAVOURITE (along with the magnesium ascorbyl phosphate 10%).
What i love about this is how well it sinks into skin (remember, less is more, you really do just do need a few drops, not a whole pipette full!).
I use it in the day to boost my antioxidants, and sometimes at night under my Marula oil. Brightening effects definitely showing, and I like the smell, it's kind of nutty.
No sensitivity on my very sensitive skin, unlike some of the harsher options.
You must try this!!

Easy to fit in routine not gritty - 07-05-2018 by

I liked TO 23% vit c but found it hard to fix in my routine because of the texture and more greasy feel. I find this one much easier to use even under make up which makes a nice mix with sunscreen for my skin. It soaks in fast, gives a nice glow and i feel it's lightening up pigment, old acne scars and under eyes.

LOVE IT - 07-05-2018 by

Great product! Highly recommended

Glowing skin without being oily - 29-04-2018 by

I really like this product, I have been using it in the mornings and find it gives a really nice glow without being oily or sticky. I haven't had an issue using it underneath makeup, but as with most of their products I only use a little bit at a time (2-3 drops) .

Good & well priced - 11-04-2018 by

I'm a fan of the ordinary products and this is part of my ordinary skincare routine. Like all their products, it's very well priced yet still packs a punch
It smooths and brightens my skin and I really believe that this product assists with fine lines.
I only use at night however as the "feel" of the product isn't great and feels a little tacky on my skin. I still use however because it's worth the results

A great vitamin c serum - 29-03-2018 by

I bought this as a way to introduce some vita in c into my skincare. This is a really nice serum, it feels great on the skin and leaves skin looking smooth and bright. I would definitely recommend this to anyone wanting to use some vitamin c as a very nice and affordable serum

High-powered vit-C product - 26-03-2018 by

I love this and highly recommend it for a daily vit-C product. I use this every evening and wake up with amazingly refreshed and brightened skin. I have a small amount of sun damage on my cheeks and this is helping to reduce it. I've just had a couple of weeks of not using it (ran out and it was out of stock) and seriously missed it.

Glowy skin in a bottle - 19-03-2018 by

The only other vitamin C product I have used is the Flash facial by REN which was water activated.

I have noticed after I use this that my skin is more glowy and bright, however I can only use it at night as it balls up under my makeup or any other skincase, which is annoying.

I generally put this on on a clean face and wait for 15 minutes or so, before using any other skincare. The texture is a little gloopy and sticky but I don't mind if I use it before bed. I also keep this in the fridge to stop it going off as quickly. I would probably try another vitamin C- maybe the Clinique one - before buying this again.

My fave Vit C - 13-03-2018 by

Ascorbyl Glucoside is a stayer in my routine. This was the first product I ever bought from The Ordinary and I'm now on my second bottle. It brightens and smoothes. At first I had a a little sensitivity to it, so I took my time, layered it in gradually and now I use daily..I have sensitive pale complexion, rosacea prone. Blue eyes, blonde hair.

Plump skin - 05-03-2018 by

I have dehydrated skin and read up on which products to use. This was recommended as was The Ordinary Squalane. I bought both and the combo worked well for me. I used this in the morning with a 50+ sunscreen then my make up and my skin felt moist all day but not oily.

Best Vit C Product - 25-02-2018 by

This is the best vit c product I have used. I do not like the silcone one in this range but this one is great.

brightening with a great price - 25-02-2018 by

This is an amazing price for this product- other comparable products would easily be double the price. It is a good, stable Vit. C product. Brightens skin, helps my acne and dark spots fade.

IN LOVE - 06-02-2018 by

Fantastic product. Makes my skin glow and has reduced the size and redness of a large keloid scar on my chest. I’ve repurchased three times and my friends have started using it too. Love it!

Great product - 23-01-2018 by

Not entirely sure what this product does but whatever it is it makes your skin glow!
Love this brand so much - all their stuff is amazing.

Acne scars has almost gone - 23-01-2018 by

This is amazing, after using this my acne scars have really started to fill out more and become less depressed. I love this!!!

Visable difference in a matter of days. - 13-11-2017 by

This vitamin C serum does what it says! Within 2 weeks of regular use my pigmentation is noticeably reduced and skin tone is clear and even. I'm impressed with the results at such an affordable price! I'm looking forward to exploring more of The Ordinary products and will be re-purchasing this one.

Love this serum! - 19-09-2017 by

I have oily skin and a lot of hyperpigmentation from my teenage years and early 20s spent without proper sun protection. Been meaning to try a vitamin c serum for years! The serum feels light on my skin and most importantly after only 2 weeks of using this product my pigmentation is visibly improving- no laser necessary - sceptic no more! And for such an amazing price.

Fantastic product - 02-08-2017 by

If you are looking to even your skin tone I suggest you try this!

After using this product for about a week I have already noticed a difference in my completion including
- reduced redness
- reduced visibility of scars

I personally hate the feeling of products on my face so when I tried this for the first time I was pleasantly surprised it sinks in instantly!
(I follow this product with The Ordinary Natural Moisturizing Factors and my skin feels amazing)

I want to be confident in my own skin and this product has definitely put me on the right track!
