What the gurus are saying

A stable form of vitamin C that doesn't oxidize is what wins gurus over, and it's less likely to sensitize than a sibling formula, so it suits skin that's touchy in winter. Praise centers on brightening and pigmentation, including under the eyes. The catch: quick results didn't show up for everyone, it's a water-free serum, and a skeptical camp found the formula disappointing.

"So I think it's on the brands to really explain it in more detail. This is great, and I'm really going to miss this one. I tended to use it in the winter when my skin was a little bit more sensitive, but I didn't want to forgo my vitamin C. This was perfect, and so I will definitely stock up with a couple of units, because it's so stable and you'll get a great shelf life on it. My skin just loves this one."

BEST VITAMIN C SERUMS - My Vitamin C Favourites
"It still gives you great results, and you still get a long-term... [...] I prefer this one to the NIOD one because I think it's more suitable for everyone and less likely to sensitize, but I still didn't get the really quick results I maybe was expecting from a 15%. I think I would rather buy a fresh, pure form of vitamin C than rely on ethylated ascorbic acid, which lasts longer, but I still don't think you get quite the potency."
THE ORDINARY VITAMIN C DISCONTINUED - What You Need To Know
"This is great because it's in a super stable form of vitamin C, which means you don't have to worry about it oxidizing, and it has a super long shelf life. So if you are stocking up during the November sale period, this is a product you can buy multiple units of and not worry about it oxidizing and going out of date before you can use it. That's definitely a benefit for people like me who don't always store vitamin C in the best way possible. I leave mine on my counter."

"Now, the ethylated ascorbic acid 15% solution is still wonderful. It can still help to brighten up your skin, address signs of aging, and protect your skin from everyday pollution. But this is a waterfree serum. It's an anhydrous serum, so it might feel a little oily because there's no water in the formula. If you like that and you don't mind that type of texture, you might really enjoy this serum."
✓Yay
"The ordinary's Ethylated Ascorbic Acid is actually very low, at about 2%, so this is an easy one. We have The Ordinary on one side and Kiehl's on the other, and of course the winner is The Ordinary again. The next one is an ingredient all of you are crazy about, especially on TikTok: hyaluronic acid. The hyaluronic acid from The Ordinary is 7 pounds, and I had to find an equivalent, and it was 111Skin."

"With Ethyl ascorbic acid, in my opinion this one was a pass. I wish I wouldn't have purchased it. I wish [...] I wouldn't have spent the money on this. That's four or five bottles of something gorgeous I could have had instead, which is much better on so many levels. With a 10 being a perfect score, I give this one a five. It's terrible. And this one I won't even hand down to anybody, because I [...] question many things about this formula, and that's really it."

Top Amazon Skincare Product Sale Picks for Amazon Prime Day Feat. Tatcha, Avene, Bioderma and More!
"They're Vitacy Glycolic Serum, which is fragrance free and combines vitamin C as well as glycolic acid, which are both really wonderful topical ingredients for rebuilding collagen in your skin. It's really hard to rebuild collagen through topical products, but vitamin C and glycolic acid AHAs have been shown to help do that. This serum is pretty expensive when it's not on sale, but if it's on sale for 30% off, that makes it a little bit easier."

"Yes, this can help with brightening, it can help with pigmentation. It works really great under the eyes if you tend to have a little bit of pigmentary issues down here, but this can also help with fine lines and wrinkles if it can get into the skin and help you stimulate collagen over time. We have these special little skin cells in our faces and the rest of our skin, they're called fibroblasts, and they are a blast to hang out with."

What the evidence says.

Independent of what the gurus think, this is what the published research supports about the main active ingredients here.

Vitamin C

Topical vitamin C is an antioxidant with reasonable evidence for dullness and uneven tone. It breaks down in light and air, so how a product is formulated and packaged matters as much as the percentage on the front.
