Works very well, very expensive.

This is a great brand all around. I have never bought anything I have not kept using. Great serum, great brand!
Elize –
Truly the best. It’s expensive, but does for my skin what nothing else had been able to do- even at the tone and make it incredibly soft and glowing. I use it as a daily moisturizer and that might be why. But it’s still worth it.

Best night serum, really concentrated. It does’t sting at all though.

Very nice oil-based serum. Really expensive, though.

I thought all Vitamin C products were pretty much the same until I tried this. One bottle, and I see a noticeable improvement in my facial skin. So glad I happened onto this in my friend’s bathroom and asked about it – it is making my skin and skincare ritual so much better!
Angela –
Well worthy the money! The only C product I need.
Patricia H. –
I just have to say how great this product is! More commercial C products do not do nearly the job this has done in evening out my skin. Love it!
Gianna V. –
This goes on so smoothly and actually ‘feels’ glowy! The percentage of vitamin C is really high but, like others have said, it doesn’t irritate at all. I use it over the Elixir essence every day. Its expensive, but again, you only need a few drops so it does last.

What can I say? This seems to be fading my brown spots very well. Highly recommend!

This oil is one skin care product that is worth the price! My sisters and I all use it religiously. People think we are a decade younger. I’m not saying we don’t have good genetics to start with, but this absolutely helps!

People ask me all the time what my skin secret is, and it’s THIS product. Instant glow, long-term evening of tone, smooth texture, healthy ‘bounce’. Easy to apply and effective! I have lost count of how many people I’ve turned on to this serum. And, i admit, I love the compliments!

Quality really does matter. This oil works better and faster than any other vitamin C product I’ve tried, ever. I can see why its so expensive – the percentage of C is the highest I’ve ever seen in a product, and its the most active, stable kind of C available. As an esthetician, I know this is true although I’d never tried this brand until recently. It is very, very effective, and the texture and weight are perfect for creating an instant glow together with nice absorption. This Tai-C serum is worth the price, and my clients happily pay it!

Never seen a serum with a C concentration this high. I figured it must be irritating, but it absolutely is NOT. It is the silkiest, glowiest C serum I have ever used, so I keep buying, even though its on the expensive side. All my little brown spots from the sun have disappeared in the 6 months I’ve been using this, and I get compliments on my skin every. single. day. I feel beautiful all the time! You can’t put a price on that.
Ella Beth –
The formula on this C serum is incredibly silky and well-absorbed, but still leaves a glow. I notice a huge improvement in my skin since using it. All Qi Formularie products I have tried are highest-quality. I recommend highly!

I find this ‘serum’ (actually an oil) to be the absolutely perfect weight and texture to use as a daily face oil. I just wear it alone, during the day, and get compliments on my skin daily.
Reginna Robins –
I use this as a multi-tasker product – it seals in moisture, acts as an oxidant barrier, and delivers a really high-percent vitamin C concentration all at once. It doesn’t irritate my face at all, though. I wear it most days all by itself.
Lianna J. –
This is the perfect C serum. I cannot believe it took me this long to find it! I wish they made it in a larger size, but the owner said she wants to keep the packaging small in order to minimize room for air and oxidation once it is opened. that makes sense to me, but still…I go through this pretty fast and I would hate to run out even for a day…
Denise Yardy –
This is the best C-serum I have ever used. It just takes a few small drops to brighten/ smooth your skin and works to keep it that way. Excellent product, no irritation and great results!
Karaline A. –
This stuff has faded my brown spots in no time flat. I have never seen a Vitamin C concentration so high in a skin care product and I was skeptical, and worried it would be really irritating, but it isn’t AT ALL. It smells great too, and my skin has never never NEVER looked better. Thank you for this!!!
Gennifer F. –
Absolutely the best out there! This C serum does so many things at one, moisturize, even my skin tone, give me an instant GLOW that is not to be believed, on top of everything else! Many days I don’t use anything else.
Ana G. –
I use this every day with the Primary Serum. I don’t need anything else, and my skin looks amazing!!
Angela –
I just logged on to say this is the best vitamin C serum ever, and saw that a lot of people already said the same. It’s true! Not surprised I am not alone because this serum is amazing!
Michelle –
You only need a LITTLE bit of this and your skin is instantly dewy! Aftet 2 bottles, used regularly, I definitely see results in the longer term too – more brightness, even tone, smoother. Thats about 4 months worth and I defimitely plan to keep buying.
Brett L. –
My very most favorite vitamin C oil!
Anonymous –
My skin thanks me for buying this serum every day.

The best Vitamin C product I have ever tried. Instant results, way above any I have seen from anything else! I am a devotee for life.
Caroline C. –
I swear this product saved my skin! It’s so healing and brightening. I get so many compliments about how glowing my skin is
Ama C. –
Could not believe how quickly my dark spots went away. Only a few drops are needed, if you use regularly. LOVE!
Carol C. –
This gives such a glow! It is really concentrated, so a little goes a looooong way. Otherwise I would think it were too expensive, but it is a 30% solution, that does not irritate at all, and it shows on my skin!
