What the gurus are saying

Waking up with plumper, bouncier skin is what gurus keep coming back to with this mask, and they credit the high concentration of collagen in the formula. It's thick and creamy enough to work as a standalone nighttime moisturizer, though gurus suggest skipping a separate moisturizer underneath to avoid pilling. Apply it after any active like retinol, and you'll want to give it time to absorb before bed.

"In here you've got collagen, panthenol, vitamin E, and a little retinoid which will over time naturally increase collagen, plus niacinamide too, so it's quite a nice comprehensive formulation. You use this as a rich moisturizer in your evening skincare routine, you put this on the skin and you'll wake up with the juiciest bouncy skin of your life, which I love. [...] If you look at the ingredients, collagen is sky high on it, which is why I think it works so well."

"This is thick and creamy. I like to use it alone after you finish using your retinol or your peptide, whatever you're using at night, instead of a moisturizer. Just use this product, don't use a moisturizer on this, it will tend to pill. This is going to literally make your skin look like you got a facial and woke up like that."

What the evidence says.

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

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.

Humectants and emollients

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

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.
