For those of you searching for instant gratification, you might be tempted by Renee Rouleau's Instant Line Filler
($62.50 for 1oz). Hyaluronic acid in the form of 'filling spheres' (whatever that means) create that just airbrushed look.
I wonder.... I do have a bottle on my desk should anyone be curious enough to give it a try and responsible enough to tell us whether it works (without subduing the lights). Just leave a comment.
I strongly suspect that filming agents such as acryloyldimethyltaurate/acrylic acid copolymer might have more to do with instant line filling than hyaluronic spheres. Nevertheless and regardless of whether or not you look younger in seconds, sodium hyaluronate is a good ingredient for retaining moisture and clinical trials have shown it to promote cell growth. Instant Line Filler also has a stable and effective form of vitamin C and squalane. Glucosomine HCI is an interesting amino acid derived from shellfish and there is a carageen from seaweed.
The squeamish should be advised that this product does contain ethylhexyl methoxycinnamate. There is some evidence that it can cause cell death and one study found it to be an allergan.
