What the gurus are saying

This serum earns praise as a multitasking hydrator that goes beyond simple moisture. Dermatologists found it can help soften fine lines and wrinkles when used alone or to complement treatments like Botox, and the formula's blend of proxalin (which may stimulate the skin's own plumping compounds) and ingredients that encourage natural hyaluronic acid production showed benefits in clinical skin biopsies. One reviewer noted it works well as a nighttime moisturizer alongside tretinoin to ease dryness and irritation, though one take flagged the formula may yellow slightly over time.

"Normally I would spend this much money on a vitamin C serum because I love the one from Geek and Gorgeous this one I got in the space NK Advent calendar"

"It's a hydrating serum that I think kind of goes beyond just basic hydration. It's really a plumping hydrating serum that contains Proxalin, which is a molecule that's unique to L'Oreal and it's a sugar molecule that's been shown to basically help reduce glycation on collagen and elastin that occurs with aging and that basically damages and makes them less effective. The Proxalin helps to support collagen elastin production along with hyaluronic acid and lactose root that's been shown to help brighten and support skin matrix building, helps to plump and reduce appearance of fine lines and wrinkles. You can use it all over as a hydrating serum with additional benefits or you can apply it and target it to specific areas on your face that you want extra plumping and smoothing, like the nasolabial folds or crow's feet. Highly recommend checking this out."

"I think of this as beyond just a hydrating serum. You can certainly use it like that, but it's a multitasking serum. You can use it to spot treat areas that have fine lines and wrinkles to help soften those areas locally, or to complement your neurotoxin injection, AKA Botox injections, to further improve those fine lines and wrinkles, or maybe even help to prolong the effects of your Botox. The ingredients are really fascinating. First of all, it contains 10% proxalin, which is a birch tree derived ingredient that basically has been shown to stimulate our skin's own internal glycoproteins and glycosaminoglycans that basically help to plump the skin and support the extracellular matrix, which helps to give our skin that elasticity and is what we tend to lose over time. In addition to hyaluronic acid, it also contains 2% licorice root along with purple rice extract that helps to stimulate our skin's own natural production of hyaluronic acid. And it's really fascinating because they actually did clinical studies performing skin biopsies on the forearm of patients before and after use."

"SkinCeuticals H.A. Intensifier is a good product with peptides and lipids, though it contains essential oils which some people may find irritating."
Mixed
"Skinceuticals has a product that combines three percent azelaic acid, which is slightly too light so kind of useless in my book, with two percent arbutin which is actually a sweet spot. I would use this more for the arbutin effects than the azelaic effect. It is greenish so if you have redness it can slightly help, but I don't think three percent azelaic acid is going to be enough. I would not buy this for redness. I would buy this if you have more pigmentation issues."

What the evidence says.

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

Salicylic acid

Salicylic acid dissolves in oil, so it can get into a pore rather than just working on the surface. That is why it has long-standing evidence for blackheads and milder acne.

Source: DermNet

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.
