14 experts · Strong agreementWhat the gurus are saying
The mix-it-yourself format is what gets experts talking: vitamin C powder meets liquid right before you use it, so you're not gambling on how long a bottle sat on a shelf. Fans love that stability and the rich feel, while others found the 15% L-ascorbic acid too irritating, and some said it mixed up gritty. Best patch-tested first, especially if your barrier is cranky.

What they flagged
The concerns the experts tie this product to, in their own words. Paid and founder takes don't count.
“The catch for me with this type of pure vitamin C serum is I have to have my barrier in a good place, when my skin is doing well I can handle vitamin C, when my skin isn't that's when I cannot, [...] because vitamin C needs that lower pH which can be irritating [...] on already irritated skin.”

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

Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.

Vitamin E is an antioxidant, and it is often in a formula to keep the other ingredients stable rather than as the active itself. It pairs well with vitamin C, though on its own the evidence for visible change is limited.
