Fresh batch, arrived in perfect condition!
Set name: Vitamin C15 (Full Size)
I was honestly nervous to order this online because pure Vitamin C oxidizes so easily if it sits on a shelf too long. Fortunately, it arrived securely packaged and completely fresh—the serum is a very light, pale yellow, exactly as it should be. Relieved to know I received a fresh bottle. Definitely recommend! ... show more

So far, so good
Set name: Vitamin C15 (Full Size)
Kylie skin vitamin C serum is my favorite, but it is not available right now, so I took a stab at this product since AI told me it was good! So far, I have no issues. It is not creamy and silky like Kylie skin vitamin C. It is more of a clear gel type of texture and it's slightly sticky but not bad at all. I like it, and I think it is having a brightening effect after only a couple of weeks. ... show more

My favorite Vit C serum
Set name: Vitamin C15 (Full Size)
Definitely recommend! I've been using this product for maybe 2 years and it's done wonders for my skin. I had a different vitamin C serum before this and this one is by far my favorite. (After adding a gentle retinol into the mix it's even better.) The one thing I will say is that it's basically like water so I usually hold a hand up to my face and rub/dab it in as I go so it doesn't run all down my face. It doesn't bother me though since it actually makes it easier to apply all over the face with very few drops. I would say a bottle lasts me anywhere between 2-3 months. I see some reviews talk about issues with packaging and spills but I've personally never had an issue with any of that so, it might depend on location or how far the package is being sent. And for anyone concerned about the product being different colors when you order a new replacement, that's just how this product works! Visit Paula's Choice website or google about the product. There's actually a variation of different colors this product can be and still be safe to use. Vitamin C is finicky like that. Another warning is be careful what else you mix this with and how you layer it with other products. Looking at all the reviews I am curious how many novice skincare folks are buying this product not realizing that vitamin C is an acid. If you don't know what you're doing then you might end up seriously damaging your skin's acid mantle which can causing irritation, burning and/or breakouts. Most of what I'm seeing in the photos looks like that's what happened too so, proceed with caution if you aren't familiar with how to mix skincare products or have especially sensitive skin. And if you use physical exfoliants (which, really no one should be but that's a separate topic) then definitely do not apply this for at least 24 hours. (Again, it's an acid. The pH is 3.1–3.5 according to their website and most retinol's are around 5-6 pH levels.) ♡ ... show more

I'm happy with the product thus far
Set name: Vitamin C15 (Full Size)
I'm happy with the product thus far. Only time will tell if it is effective. I found the packaging to be less than I would expect from a Paula's Choice product. The clear plastic "stopper" that is supposed to help prevent oxidation is not attached to either the dropper mechanism or the bottle. I have no idea if that is the way it is supposed to work (pretty much free floating), but it makes screwing the top back on to the bottle more difficult. I had ordered a second bottle which hasn't been opened yet. If the same apparently faulty assembly exists with the yet unopened bottle, it will be the last bottle I purchase. Sorry to say that, but the quality of the container is not what I expected from Paula's Choice. ... show more

Set name: Vitamin C15 (Full Size)
I love other Paula's Choice products (I exclusively use PC AHA/BHA and retinol), so I was both surprised and disappointed to find this product consistently abysmal. I have now ordered this product three times (in the sample size each time, as Vitamin C in L-AA form degrades quickly following exposure to light/air)-- once directly from the PC website, and twice through Amazon. Each time, this product was already bright amber in color (including the time I ordered directly from the PC website), indicating late stages of oxidation. This also smells bad, as other reviewers have noted (kind of like hot dog water)-- some of that is just because vitamin C smells, but some of that is due to the fact that the product was spoiled. L-AA, of course, degrades quickly, and some oxidation is more or less inevitable unless you're formulating your own vitamin C products at home. However, this is theoretically stabilized by ferulic acid and tocopherol, so I don't understand why the product was at such late stages of oxidation each time I received it, and as a result I'm concerned they're not doing effective quality control or tracking sell-by dates. Moreover, it's fairly damning that this is packaged in an eyedropper bottle, especially since part of the Paula's Choice Gospel is packaging, and this packaging is dreadful. Bottom line: this product is either worthless or actively harmful. At this price point, that's ridiculous. ... show more

Working great

Loving it! No issues with oxidation on the skin. Feels good and not to sticky and most importantly works great reducing dark spots.
