What they flagged

Vitamin C smell lingers on skin

What the gurus are saying

This propanediol-based vitamin C serum feels lighter than expected for a non-water formula, though it carries a lingering vitamin C smell. Gurus found it performs decently as a vitamin C treatment, but note it lacks the ferulic acid and vitamin E pairing that makes the classic trio so potent. The airless packaging means you'll want to refrigerate it and start using it right away to protect the formula from oxidizing.

"It seemed to do the trick, it seemed like a decent vitamin C serum, although I do love the combination of vitamin C, ferulic acid and vitamin E, a proven trifecta, which this doesn't have. [...] A bottle lasts a long time since I just use it on a couple areas like my nose and chin, [...] so it's a more high end brand but it still lasts a long time."

"It has centella asiatica leaf extract, Asiatic acid, the whole plant, and it adds this calming sensation to the serum. They triple collagen in here, you have hydrolyzed collagen, soluble collagen, so this is a really good firming, aging, skin tone reviving and brightening serum that just adds this radiance to your skin. I'm not usually into such high percentage serums, but with its calming action, I'm tempted. I have two of them."
