What the gurus are saying

The packaging is a genuine dealbreaker for some gurus, even as they praise the formula itself. The vitamin C derivative sits at a solid 2-3% (within the active range), backed by niacinamide, allantoin, and green tea for soothing and anti-inflammatory support, and the enzyme blend works well for those who struggle with chemical exfoliants. However, the open bottle design exposes the formula to air and light, which matters for vitamin C stability. Those concerned about oxidation may want to decant it into an airless pump or use it quickly.

"This formulation has 3-O-ethyl ascorbic acid pretty high up in the ingredient list, so we know it's in there at a pretty high amount. That derivative is only shown to be functional between 2 to 5%, but it's nice to know it's in there at a really good amount, at least it's not below that 1% line. There's also niacinamide and allantoin for soothing the skin, and tocopherol and folic acid to increase the potency of that vitamin C."

"They've gone in for 30% ethos scoring acid beautiful vitamin C and it's a ingredients so you're looking at a good 2 to 3% this in the therapeutic index again great percentage. I would say I love this formula but I hate the packaging and if Innisfree put this into an Airless pump I would recommend it for you but as it is as it stands as beautiful as the packaging is this is not one I would use for my face or recommend to my global skin of color family."

"But again I don't like the packaging in terms of the best formulas on niker for vitamin C it would be these three it would be minimalist dermo and deconstruct but my advice for all three would be to change the packaging to LS pumps"

"This is the Green Tea Enzyme Vitamin C Brightening Serum from Innisfree, a new release sold at Sephora, with suspended oil droplets in it, made with 3-O-Ethyl Ascorbic Acid. Since it's a new release I don't have long term thoughts on it yet, but it did kind of jump in and become my primary vitamin C for these past few days. It's really easy to use, and I like the enzyme ingredients, those seem to work for me even though I struggle with a lot of chemical exfoliants."

"Innisfree Green Tea Enzyme Vitamin C Brightening Serum is $32. This has 30% ethyl ascorbic acid, which is also an ester form. It also has green tea for anti-inflammatory properties. It is a serum and it has no HA, and I love that."

"It's okay for sensitive skin. I put it at intermediate, but it's definitely good. The texture is a little different because it's slightly transparent and has little capsules, and when you rub it in it feels amazing, like a primer, and it doesn't tickle at all. It also has a toning serum, so I recommend it for young skin who want to try vitamin C too."

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.

Niacinamide

Niacinamide has evidence behind it for redness, uneven tone and supporting the skin barrier, and it is usually well tolerated even by skin that reacts to most things.

Tranexamic acid

Tranexamic acid has a growing body of clinical evidence for melasma and the stubborn patches of pigment that other ingredients struggle with.
